Types of Commercial Heating Options

Types of Commercial Heating Options

commercial heating repair in MOAmerican Services heating systems installation in Missouri knows that installation of commercial heating systems using sustainable resources are a viable option that should be considered. These systems employ energy sources such as solar and geothermal power, leaving no footprint on our environment.

Heating, ventilating, and air-conditioning (HVAC) these systems are not only good for the environment, but over time they will perform more efficiently, generating energy cost savings and decreasing the carbon footprint that “traditional”options such as oil and gas leave behind.  Because of the relatively high initial installation costs, this type of commercial heating system is often reserved for the larger facilities.  Fortunately these costs are becoming more affordable as tax breaks and government incentive programs become more prevalent.

Oil or Gas Steam Heating Methods

Choosing an oil or petroleum steam powered commercial HVAC system, while definitely not the most efficient, is one of the oldest methods of commercial heating installations. The oil or gas is used to boil, manufacture and subsequently pass steam through the pipes-generally considered one of the least efficient processes, and at the same time, most harmful to the environment. Steam heating methods take longer than most systems to circulate heat because of the delay between the boiler being fired up, and the heat finally circulating thru a network of pipes, ending up in the radiator unit.

Gas or Oil Water Systems

An additional method for heating commercial property is using a water-driven HVAC system. Similar to steam heating in overall concept, the water heating method uses a boiler to heat water, which is then subsequently passed through a pipe network to radiators positioned throughout the facility. These water heating systems are some of the least productive heating methods and also less than ideal from an efficiency perspective. One reason for this is that you have to clear the air in the system each time the heat is engaged, causing delays in heating which results in inefficiencies.

Heat Pump Alternatives

Implementing a heat pump commercial heating alternative is the most favorable commercial heating option and is an efficient means of heating a building. This process is similar to the technology used in refrigerators, essentially extracting heat from cold. Because these types of systems do not require a fuel source (gas or oil) to function, they are very cost effective systems.

Tips for Buying a Used Commercial Range

Tips for Buying a Used Commercial Range

commercial restaurant equipment in PA Used restaurant equipment is a big temptation for anybody who wants to save money today, and with rising food and utility costs, who doesn’t want to save on expenses? A used commercial range is an attractive proposition for restaurant owners, especially new restaurant owners. However, if you are considering a used commercial range, be sure to properly setup a routine maintenance schedule to get the most out of your investment.

PURCHASING TIPS

Follow these tips when shopping for a commercial range:

– Go with gas. If you have made the decision to buy a used commercial range purchase one that runs on gas! Any piece of gas cooking equipment is pretty reliable if purchased used. This is because they’re designed simply with very few working parts, whereas electric ranges can have heating elements go out, and they’re expensive to replace.

– Top configuration and base type.
There are several different range top configurations to choose from. Be sure to read the product description and find a configuration that suits your needs.

– Inspect the unit. Physically inspect the used Range before you purchase it. This could be difficult if you are shopping online or at an auction. During your inspection check the burner heads and pilot ignition for clogs which is a common deficiency. Also if there is a cabinet or oven base,  check the hinges and seal. A bad seal will decrease cooking efficiency and increase energy costs.

– Call the manufacture with any questions. If you have any questions about the used commercial range, the manufacturer will be able to diagnose any potential problem you see  and provide repair estimates. If the potential repair is too expensive, or repairs cost more than the used price of the equipment itself,  go shopping elsewhere.

HVAC Upgrades

HVAC Upgrades

HVAC Services in MOAmerican Services commercial HVAC installation in Saint Louis knows that it’s feasibly possible to replace one particular component of an HVAC system and not have to repair or replace any other for the ten year life of an HVAC system. However it’s highly unlikely, Certified HVAC technicians at American Services will verify this thru vast experience. If upgrading one component is a consideration, you may want to take a look at the whole picture.

“You wouldn’t want to replace one piece and not consider the other pieces,” says a certified tech for a large west coast HVAC installer “If you have a chiller that’s reaching the end of its useful life, you have to consider the condition of the cooling tower. It’s a mistake to replace the component of a system that has an obvious problem and not have the foresight to take a holistic look at it and say, ‘the chiller’s 30 years old and it has a problem, what else is that old?'”

One of the first and most important places to start inspecting when looking for other areas that might be affected by an upgrade is the control system. If you are operating with a legacy control system, you’re running the risk of either limiting your upgrade options or not getting the most out of them. These old outdated control systems will keep your system running inefficiently even with an HVAC upgrade.

“I wouldn’t limit myself with an old BAS or energy management system and have that tail wag the dog, if you will,” another HVAC contractor says. “I wouldn’t say, ‘since the controls can’t handle certain types of equipment, let’s not go down that road.’ I would start with the main equipment and then work from there.” If you’re going to be there five years or longer, then I would be looking at upgrading,” he says. Stretching a system’s lifespan while repairing when needed becomes a more attractive option.

restaurant maintenance in Missouri” href=”http://www.as-stl.com/customizable-preventative-maintenance.html”>restaurant equipment maintenance  in St. Louis knows that maintenance managers have many options to reduce power usage and extend the life of commercial refrigeration units including coolers, freezers, and ice machines. Here is a short but extremely important list of suggested maintenance tips that you may want to implement at your facility;

– Gaskets: refrigeration systems work hard to achieve proper product temperature. Routinely inspect the door gaskets or seals on all coolers and freezers. Check for tears, rips, or missing magnetic strips in gaskets. If gaskets are found to be worn out replace them immediately. You’re losing cold air, and making your system work harder to replace that air. This increases power consumption and lessens refrigerator systems’ life span.

 

– Door hinges and closers: most doors and hinges on refrigeration units close properly utilizing spring cartridges.  Be sure to inspect these mechanical hinges insure proper operation. Larger cooler and freezer doors- especially walk-ins normally use hydraulic door closers. Doors that are not closed all the way in this matter contribute to excessive run time, inefficient use of energy; shorten the life of the equipment and causes evaporator coils to ice up.

 

– Calculate accurate internal food temperature: using a product sensing thermometer, is far superior to an air sensing thermometer in refrigeration’s units due to rapidly changing ambient conditions. Refrigeration systems using an air sensing thermometer only reveal how cold the air is in a refrigeration unit at the moment you open it. There are situations when it does not give an accurate picture of a product’s actual temperature. Product sensing thermometers are much more accurate.

To schedule maintenance on your walk in freezer, cooler, or refrigerator unit, be sure to contact American Services refrigeration repair service in Saint Louis MO today.  You won’t be disappointed!

 

 

Save Energy Costs on Commercial Walk-In Cooling Systems

Save Energy Costs on Commercial Walk-In Cooling Systems

commercial cooling service in MOAmerican Services heating and cooling services in Saint Louis MO knows that one of the best ways to insure energy efficient refrigeration performance is knowing when maintenance  issues are minor or major.  Hiring a certified cooling and refrigeration technician yearly to inspect your system can teach you a lot.

One way to save on energy costs is to purchase strip curtains for walk-in units to minimize the amount of hot air entering the cooler .Do not allow staff to leave cooler doors propped open for extended periods of time, this causes condensers to work much harder than normal.  In some instances a simple “Keep Door Closed” sign can be part of the easy solutions performed by the owner or staff saving additional energy costs on utility expenditures.

Another common infraction that can be an easy solution to fix is to remind employees to turn off the lights when they exit the walk-in. Not only do the bulbs waste energy when the cooler is empty, the lighting also produces heat which causes the condenser to work harder to maintain a cool temperature. In addition, try replacing regular bulbs with fluorescent bulbs in the cooler. They give off less heat and are more energy efficient and less likely thaw products in the walk-in refrigerator.

Train all managers not to set the holding temperature too low on units because that will overwork the equipment. Walk-in coolers should be kept between 35 and 40 degrees and freezers between -5 and 5 degrees. Inspect periodcally and make sure all cracks are properly sealed and replace worn gaskets. Do not stack anything around the coil; this restricts airflow and decreases the performance of your cooler and decreases condenser longevity.

Set defrost frequency at minimum requirements (every four to six hours for 20 to 40 minutes depending on the amount of traffic in your walk-in).

With a little direction, your staff can play a contributing role in properly maintaining refrigeration equipment. These simple preventative measures can save restaurant owners a great deal of money in energy and repair bills, a help to avoid costly breakdowns.

Tips for Maintaining Cooling Towers

Tips for Maintaining Cooling Towers

commercial cooling repair in MOAmerican Service heating and cooling maintenance in Wentzville knows that the hot summer and cold months place unusually large demands on cooling systems, so if your cooling tower and related equipment are not properly maintained, you can’t expect them to be in good physical shape, there could be a loss of process efficiency, damage to downstream equipment, resulting in loss of production. These are just a few of the malfunctions encountered when operating without a preventative maintenance checks and services schedule (PMCS).

Similar to overheating the engine in your car, the loss of cooling capability and subsequent dangerous rise in temperature in cooling towers during hot summer months can result in a number of serious consequential “systemic” problems. Some of those include; complete paralyzing of tower controls, destruction of equipment, and loss of product due to inferior quality issues.

“Like your car, when you run a cooling tower in the red, you are going to see consequential damage,” advises Tom Ryder, a longtime cooling tower customer support specialist. “When you continuously run a car in the red during the heat of summer, you are exposing yourself to a series of heat-related problems, including damaged gaskets and seals, premature cylinder wear, warped cylinder heads and even catastrophic engine damage. When a cooling tower is suffering from a lack of preventive maintenance, you could experience over-heating equipment, increase in scrap material, refrigeration losses, heat exchanger inefficiencies, and other severe operational consequences.”

Cooling towers play a critical role in cooling process equipment used in pulp & paper production, petrochemical processing, manufacture of plastics, metals and textiles, the processing and storage of food, beverage and pharmaceutical products, and many HVAC systems.

If cooling towers are not kept in good working condition with preventive maintenance, the additional ambient heat of the summer months will tax their cooling capacities, making them “fatigued”, which can in turn put a strain on system equipment and processes downstream.

HVAC Energy Consumers

HVAC Energy Consumers

commercial HVAC services in MOAmerican Services commercial HVAC services serving Jefferson County knows that many commercial and institutional facilities typically have more motors operating in their HVAC systems than most maintenance managers realize. Because these motors use so much energy, they are a great place for facilities managers to begin energy efficiency evaluations with a shift towards making a significant impact on facility energy use. By far the leading cause of energy inefficiency with HVAC system motors is a mismatch between the motor’s rated horsepower and the load it is driving. Most HVAC system motors are induction motors.

While these motors are efficient and reliable, their efficiency drops off significantly when they operate under part-load conditions. By properly matching motor horsepower to system load requirements and implementing a comprehensive monitoring system, operation managers can achieve major energy savings immediately, as well as adding to the longevity of HVAC components-in this case, internal motors.

Accomplishing this goal requires that facility managers conduct an inspection survey on HVAC system motors to identify those that are significantly oversized for the application. The goal of the process is to develop a comprehensive list of applications that use motors, including information on the motor horsepower, the load it is driving, and the age and rated efficiency of the motor.  Detailed documentation of HVAC components will insure energy efficient operation

The focus should be on motors that are oversized or have exceeded their operating life expectancies.  Replacing older, oversized motors with properly sized ones offers two benefits. First, matching the motor horsepower to the actual load improves the operating efficiency of the system.  Additionally, changes in motor design have resulted in a generation of motors that have operating efficiencies 2-8 percent higher than older, standard motors. Coupled with the improved operating efficiency that comes from matching the motor horsepower to the load, the improvement in efficiency can provide a relatively quick payback for facilities.

Maintenance of Restaurant Equipment for Pizza Kitchen

Maintenance of Restaurant Equipment for Pizza Kitchen

restaurant equipment repair in MOAmerican Services restaurant equipment maintenance service in St. Louis knows that used equipment is not the only thing that requires care in a pizza kitchen. The supplies are equally important, as they are what bake, transport, and serve your pizza to your customers.

Wooden Pizza Peels

Wooden Pizza Peels require routine maintenance in order to ensure longer service life. By following the steps below, you can extend the life of your peels;

  • Apply a light coat of mineral oil to act as a sealant for the wood and prevent it from splitting; it also acts as a water proofing agent. Only use mineral oil; vegetable or olive oil will become contaminated, violating health codes.
  • Keep all wooden kitchen equipment dry, water can cause damage to wood products. Moisture can also cause the board to warp.
  • Keep Pizza Peels floured when in use. When using the wooden peel to insert or extract pizzas from the oven, be sure to lightly dust some flour on the surface. It quickly absorbs any extra moisture and allows the pizza to slide easily slide on and off the wooden peel.
  • Brush it clean when not in use. By keeping it clean, you can retain the life of your peel. Food crumbs, melted cheese or pizza sauce can collect on the peel and will make the surface uneven.
  • Leaving your wooden peel on a hot surface will warp it very quickly. Once the wooden peel is warped balancing a pizza on it can be quite a feat. If your wooden board is already warped you can try to straighten it by laying it out overnight with the warp (curved side) facing upward. In most cases this significantly reduces the problem. If the problem isn’t resolved, it is time to replace it.
  • Pizza Screens and Pizza Pans require special cleaning to keep them from rusting or warping, wash in warm soapy water. These items should be hand washed and gently dried and placed in a safe flat area in the kitchen. Avoid abrasive chemicals or scrub pads.

 

Tin and Aluminum Pans

  •   Whether natural finish or hard coat anodize, these pans can scratch if scrubbed with abrasive pads. Once the coating is scratched the pan can rust once the pan is rusted discard it! Use a towel to dry your pans and screens before storing. This can keep them from rusting.
  • Tin and hard surfaces require a little more care than just cleaning. They require seasoning. This simple process can not only increase the life of your pan, but reduce your clean up time and improve the taste of your pizzas

Radiator Heating Systems

Radiator Heating Systems

heating installation in MOAmerican Services commercial heating service near Webster Groves knows that there are two commonly used types of radiator systems for heating commercial installations; steam systems and hot water systems, or possibly a combination of the two.  The type used in your workplace may vary based on needs, structure size and materials available when the structure was built. Construction methods and practices varied greatly over the years. Regional building differences may also play a role in what type of system you have.

Steam

Steam radiator systems use a boiler to boil water to create steam, which in turn moves through a series of piping without the need for pumps.  One of the problems with this systems is you must wait for the steam to warm back up after shutting down.  This is considered an inefficient method.  Steam generally moves around the heating system at pressures of around 1 lb. per square foot, allowing radiator temperatures to reach up to 215 degrees F.

Water

Hot water heating systems heat water in a boiler before pumping the water around the system to heat radiators within a building. Hot water heating systems are commonly used in newer built commercial installations and residential applications and the water temperature in the system is usually limited to 180 degrees.

Formula

If you’re interested in calculating the temperature of each radiator within a heating system, the equivalent direct radiation is multiplied by the amount of heat produced by a boiler per hour. The EDR is the square footage of the radiators within a home, while the heat produced by a boiler is measured in British thermal units. Steam boilers produce around 240 BTUs and hot water boilers produce about 170 BTU’s.

Extend the Life of Refrigeration Equipment part I

Extend the Life of Refrigeration Equipment part I

refrigeration service near St. LouisAmerican Services walk in freezer and refrigeration maintenance in St. Louis County knows that maintenance managers have many options to reduce power usage and extend the life of commercial refrigeration units including coolers, freezers, and ice machines. Here is a short but extremely important list of suggested maintenance tips that you may want to implement at your facility;

– Keep Condenser Coils Clean: this includes condensers located on coolers, freezers, and ice machines. The condenser coil acts as the heat exchanger on refrigeration units. The condenser coil is the coil located on the outside of the unit and it expels the heat from refrigerant by passing it through a coil with the aid of a fan. CAUTION-it is absolutely critical to keep this coil unit clean for proper operation of the unit. Failure to do so WILL result in expensive repairs including but not limited to complete compressor failure, fan motor failure, tubing restrictions, burnt wiring, and electrical connection/thermostat failure.

-Consult a certified refrigeration systems maintenance service company to evaluate your refrigeration system at least twice year: these certified technicians available at American Services, are a good source of preventive maintenance tips and suggestions that can be used between formal maintenance operations. Your routine inspections should be done frequently. A clean condenser coil is one way to GO GREEN by saving on power consumption and greatly prolonging the life of the equipment.

-Unit Clearances: in order to ensure proper air flow is maintained around the condenser coil, maintenance staff should keep a minimum of two to four inches of clearance around sides and back of self-contained units. Five to eight inches of clearance is optimal, though some commercial kitchens may not accommodate this. Jamming coolers against directly against the wall is a sure way to expand the most amount of energy and guarantee many maintenance problems.
