Commercial Refrigeration Maintenance Tips

refrigeration service in MissouriAmerican Services refrigeration maintenance service near Chesterfield knows that commercial refrigeration is considered the center of any food service business and can create major problems for when the unit breaks down because of poor maintenance. While no refrigeration unit lasts forever, there are several things you can do to extend the life of your refrigeration system.

Commercial Refrigerator Cleaning Tips:

NOTE: Insure that your refrigeration unit is unplugged before you begin any cleaning of your unit.

By keeping all of the mechanical parts of your commercial refrigerator wiped clean daily, you are taking the first step to keeping your unit operating efficiently and adding longevity to your system. There are several parts of a unit that should be cleaned regularly with warm soapy water and a cloth, be sure to rinse and dry thoroughly.

Condenser Coil

The condenser coil location on a unit can vary, located inside or outside, and can be found by checking the owner’s manual or asking the installation technician to point the unit out to you. This part should be cleaned at least once a month to keep it free of dust, dirt and lint. This is a critical component, if not maintenance properly this element could potentially shut your operation down.

Clean the condenser coil with a commercial condenser coil cleaner, which can be purchased at most kitchen equipment retailers. CAUTION Brush the condenser fins from top to bottom and never side to side. Once you have completed cleaning the fins, straighten any bent fins with a comb, this will ensure proper condenser coil performance.

Fan Blades and Motor

Fan blade and motor units on commercial refrigeration systems should be cleaned a minimum of once a month. Using a soft cloth run over both the motor and the fan blades. If it is necessary to wash the blades, cover the motor with another dry cloth so that the moisture does not cause damage to the motor.

Inside Your Unit

It is important to remember not to use any abrasive agents/cloth, steel wool, caustic cleaning chemicals or bleach when cleaning the interior of your refrigerated unit. These products can not only cause damage to the finish of the refrigerator, they can also leave behind strong chemical scents (poisons) that can adversely affect the flavor of the food. Use a solvent of warm water and mild soap to clean the inside of your unit, and be sure to rinse thoroughly.

Alternate Heating Sources for Commercial Greenhouses

industrial heating system in MOAmerican Services industrial heating equipment repair in St. Louis knows that the type of fuel that is best for commercial greenhouse heating depends on many factors such as; price, convenience and availability.

Some fuel sources put out a higher heating value than others.   A good method for comparing the cost of fuel is by utilizing the million Btu basis. In other words what is the cost of one million Btu’s of heat? By definition, one Btu equals the amount of energy required to raise a pound of water 1ºF. It takes 8.3 Btu’s to raise 1 gallon of water 1ºF.

Gas Vapor Fuels

Natural gas is one of the most economical and clean fuel sources available today, although it is not always available to industrial greenhouse owners in all geographic areas of the country.  Natural gas requires no on-site expensive storage equipment as it is piped directly from transmission lines. Natural gas burns cleanly, requires little equipment maintenance, and may be used in central boilers or remote unit heaters. Some suppliers include an “interruptible clause” which allows them to interrupt the supply in time of extreme need, usually during cold spells when fuel is needed to heat homes. Locating and securing a backup fuel supply and equipment to burn it is essential under these conditions.

For larger volume users, it is best to buy “direct purchase” from one of the large suppliers. Adding the transmission cost through the pipelines will give you a total fuel cost.

Propane (Liquefied Petroleum Gas) is a clean, gaseous fuel similar to natural gas. It is derived from a byproduct of oil refinery manufacturing or by stripping natural gas. It is liquefied by a moderate pressure process at normal temperatures. Even though propane is more expensive than natural gas it can be readily obtained where natural gas in not available. Maintenance is minimal, but a storage tank, preheater, and pumping network costs must be considered.

Propane is best purchased by the transport load which requires a 30,000 gallon tank.

Fuel Oil #2 #4  #6

No. 2 oil is usually comparably priced with natural gas but may be more expensive in some locations especially where it has to be transported a long distance from the supply point. It is a relatively clean fuel that demands slightly more burner maintenance than gas. Oil requires on-site infrastructure; above ground storage tanks that must have a containment in event of a leak or spill. Oil stored in outdoor, above-ground tanks may become difficult to pump in environments where temperatures can hover near 0ºF. Insulated tanks or additives to the fuel protect against this hazard.

No. 4 and 6 oils possess a higher heating value than No. 2 but because of low sulfur emission restrictions, they are usually similar in price. These oils require a preheating and greater attention to equipment operation. They are subject to the same storage and temperature limitations as No. 2 oil

Maintaining Indoor Air Quality for HVAC Systems

HVAC industrial maintenance service in MOAmerican Services industrial HVAC preventative maintenance service in Saint Louis knows that one of the most important issues that cannot be ignored when scheduling the priority of HVAC maintenance is indoor air quality. The operating condition of HVAC components plays a critical role in producing indoor air quality. A well scheduled preventative maintenance system program will not only protect occupants from poor IAQ, but also protects the organization from law suits, adverse publicity and potential code violations — all of which can have an impact on the HVAC operating system.

The facility executive is responsible for allocating to budget managers how maintenance impacts IAQ. The budget funds earmarked for HVAC system maintenance are very small in comparison to the potential costs related to poor IAQ issues and their related fallout.

Inspect and identify areas where the facility is experiencing possible IAQ issues. Implement a maintenance plan for dealing with those issues, including both on the spot corrections and long-term preventive measures, and what that plan projection may cost. Facility managers can identify other similar organizations that have experienced similar IAQ issues and the impact that those issues have had on those organizations, including corrective costs, downtime, fines, and litigation.

Present documentation on the condition of HVAC components, its maintenance operating requirements, the budget allocated for those maintenance activities, and the consequences of not performing that maintenance. Without documented support, facility executives run the risk of being perceived as crying wolf, resulting in HVAC upgrades and installation requests being turned down.

The tone and theme of every funding request should be tied to cost avoidance and value. Avoid request based solely on opinion, dollars and cents will be the overall indicators.

Commercial Cooking Equipment Available for Restaurants

restaurant equipment for cooking in MOAmerican Services restaurant equipment for cooking near Clayton knows that today’s restaurant owner has the choice of gas or electric when it comes to cooking ranges, which now come in a wide range of options.

Some very popular cook top ranges are inserted into a countertop and have a matching wall oven that is installed separately. There are free-standing models–range and oven combos–that have panels on both sides and can stand alone in the kitchen and can be moved around conveniently. There are also slide-in models, which have side panels that can fit between two cabinets. Then there are drop-in units, which are powered by electricity, and are installed between cabinets on a pedestal. Here’s an overview of the types of ranges and combos you’ll find on the market today:

The Cook top and wall oven set

This style of cooking equipment offers more flexibility in terms of placement because the cook top and wall oven aren’t connected. However, it requires more custom installment preparation/carpentry expertise in many cases than a freestanding range. Estimated Price: $200 to $1,000 for cook tops; $200 to $2,000 for wall ovens.

Freestanding ranges

The range and oven are molded all-in-one. These typically cost less than cook top and wall oven combos. They are normally easier to install in most cases, but the oven and range height are fixed and some allowance for height must observed. Price: $700 to $2000

Gas fired Stoves

These fire up quickly and are a favorite of chefs and housewives alike. They are powered by clean natural gas or liquid propane, which you have to buy, usually on a monthly basis. They can come with unique burners for very fast high-temperature heat and for gentle low-temperature heat for simmering. Look for sealed burners for easier cleanup. Price: $250 to more than $21,000

Dual-fuel

Gas cook top for quick response with good temperature control, including an electric oven for more even heating Price: $850 to more than $6,000

With electric ranges you have less control over heat output–for example, water can take longer to boil. However, you can get better overall performance from the oven. Models are slightly less expensive than ranges but also cost a bit more to operate from month to month. Estimate Price $300 to $2000.  Most commercial-style ranges have at least four and sometimes up to eight burners. They generate high heat output (typically 15,000 Btu/hr.), which requires more cooking finesse. One downside of these ranges: They sometimes have a high-repair history.

Care for Commercial Refrigeration Systems

commercial refrigeration service in MOAmerican Services commercial refrigeration repair near Overland knows that performing regular preventative maintenance can significantly increase the life and efficiency of your commercial refrigeration components and system.

According to the latest information from a consortium called Focus on Energy, “commercial refrigeration can account for as much as 50 percent of a restaurant’s total energy bill.” Further, the consortium stated; ”implementing routine preventive maintenance, restaurant operators can save between 5 and 10 percent on refrigeration energy costs.”

In most cases, the maintenance required is simple, easy tasks that could be performed by the business owner or staff, preventing costly service and repair bills.

Basic Refrigeration Preventive Maintenance
Formulating a daily, weekly and monthly preventative maintenance checks and services schedule will allow for proactive system maintenance and familiarity with your system.

Some common maintenance checks include:
1. Clean evaporator and condensing coils every 30 days. Some professionals suggest that only soap and water be used, harsh chemicals should be avoided. Another method is to use three parts water to one part de-greaser mixture with a soft-bristle brush. Be sure to rinse thoroughly with water when you are done cleaning. Keeping a spray bottle convenient for flushing, and the residue is easily mopped away. NOTE-when cleaning condenser coils, be sure to always scrub with the coils-up and down. Never, scrub side to side, as it will  damage the coils.
2. Clean fan blades to reduce drag and excessive wear. You will need to disassemble the fan cover and wipe it down as well. A common de-greaser solution is fine for this. Be sure to rinse thoroughly when done. Have a service technician perform calibration checks to insure the fan motor is running at an optimum RPM level.
3. Insure all condensing units are clear of all trash and weeds that may be wrapped around the  condensing unit intakes located outside in order to maintain adequate airflow and optimal performance.
4. After cleaning, be sure to lubricate door hinges annually. Cooler doors that do not operate properly can cause a vacuum causing the unit to have to work harder to maintain the proper temperature. Spring hinges that automatically close are ideal for high-traffic walk-in coolers and freezers.
5. Inspect for decay in the insulation on suction lines between the condensing unit and evaporator coil. This can cause condensation and water damage. Replace decayed section immediately.
6. Check door sweep for tears. Periodically have a professional inspect electrical control connections to ensure they are tight. Loose wires can result in high amperage, which will increase the amount of energy used by the unit and may also pose a fire risk.
7. At least once a year, get a professional technician at American Services to check to ensure that drain lines are clear of debris.

Industrial Warehouse Heating Systems

industrial heating service in MOBased on the major improvements in high energy efficient infrared heating, warehouse application of infrared heaters can now be considered cost effective and environmentally sustainable-even when heating large enclosed structures.

Infrared heat can be described as long electromagnetic waves located near the visible section of the electromagnetic spectrum which characteristically radiates energy outward. An electrically operated infrared heater consists of an element or filament (the orange wire you see) – composed most often of tungsten – which gives off heat.

A radiant gas heater uses the heat from a flame produced by fossil fuels like propane or a natural gas to create infrared energy. The radiant heat waves produced from the element or gas-flame are then reflected off of a polished surface and channeled in the direction where the heat is needed. Infrared energy can be absorbed by objects, surfaces and people as heat.  Air molecules are not important for the transportation of heat energy. Very little energy is lost due to either convection or conduction because it is not a critical part of infrared wave movement. Radiant waves are able to flow thru materials more quickly and more effectively than less efficient convection heat methods or UV lamps.  This enables the infrared heating system to be a far more efficient process for large areas such as warehouses, garages and sheds Large installations like warehouses are often used in manufacturing processes and for industrial purposes, as well as storage of goods, and agriculturally for livestock and greenhouse activities. In regions where the climate changes rapidly during the winter months, or for temperature-sensitive manufacturing processes, drastic changes in temperature can and will cause costly damages and result in malfunctions of equipment.  Maintaining a consistent temperature could prevent some of this damage and save costly repairs and replacements.

Warehouses are typically large areas and therefore the process of heating the space may require more than one heater to be effective.

Industrial heating service requires a high level of technical experience.  At American Services industrial heating equipment service near Maryland Heights, we are proud of our ability to service our industrial clients in a professional manner for service and repair of industrial heating and cooling equipment.

HVAC Made Easy

HVAC service in MOThe term HVAC is an easy way to say Heating, Ventilation, and Air Conditioning. This is a combined network of building systems that regulate the inside temperature of the buildings structure, and, in some applications, the ventilation and air quality as well.
Understanding the principles of HVAC design will allow you to maintain system efficiency. It will also include the basic layout of system functionality and the contributing factors that determine the size and capacity of the components installed within the system.
Once you have a working knowledge of the basics, move on to information concerning the air conditioning systems. It will help you to learn about the various components that make up an HVAC system. An example might be, the air conditioning portion of an HVAC system requires a refrigerant coolant to effectively cool the air inside the installation, and this means the various refrigerants that can be found in air conditioning systems need to be understood. You will also learn about the important details of HVAC system installation, including the configuration of compressor and condenser unit placement, in addition to heat exchangers, zones, and controls.
Basic Principles of HVAC System Design, Operation and Determining Capacity Requirements

When upgrading a current HVAC system or getting ready to build a new system in a commercial building, one of the most important design considerations is correctly calculating the heating and cooling loads that the system will support.
