Alternative Heating Sources

Alternative Heating Sources

solor heating in MOAmerican Services Heating and Cooling installation service in Missouri knows that there are many options when it comes to commercial heating systems.

One such option is for heat transfer fluids.  If you are considering solar heating heat transfer systems, be sure to consult the local authority in your area to find out what exactly is required for your geographic area.

Water is one type of substance that is effective as a heat transfer fluid, particularly with its low viscosity property which makes it easy to pump. Drawbacks are its low boiling point and high freezing point, and the fact that water can be corrosive and cause mineral deposits.

Glycol and water mixtures are made up of a 50/50 or 60/40 glycol-to-water ratio. Ethylene and propylene glycol make up the properties of antifreeze.

Hydrocarbon oils have a higher viscosity and lower specific heat than water meaning they need more energy for circulation.  With a low freezing point, these types of oils tend to be relatively less expensive than some others.     The basic categories of hydrocarbon oils are synthetic hydrocarbons, paraffin hydrocarbons, and aromatic refined mineral oils. Synthetic hydrocarbons are relatively nontoxic and require little maintenance. Paraffin hydrocarbons have a wider temperature range between freezing and boiling points than water, but they are toxic and require a double-walled, closed-loop heat exchanger. Aromatic oils are the least viscous of the hydrocarbon oils.

Refrigerants are commonly used in refrigerators, air conditioners, and heat pumps as the primary heat transfer fluid. They generally have a low boiling point and a high heat capacity which enables a small amount of the refrigerant to transfer a large amount of heat very efficiently.

If you currently own a refrigerant-charged solar system that requires maintenance, contact us today at American Services and we will sent out a qualified technician.

Active solar heating uses solar energy to heat transfer fluid or air, which then transfers the solar heat to an interior  storage system for later use. Solar heating systems can be implemented as a supplement to other heating systems such as radiant heating, boilers, heat pumps, or forced-air heating systems.

Active solar heating systems are actually most cost-effective in cold climates that have good solar resources.  Liquid and air systems are good choices for forced air supplemental heating. Note that commercial systems usually come with warranties of 10 years or more and usually last much longer.

Choosing Restaurant Equipment- Draft Beer Beverage Dispenser

Choosing Restaurant Equipment- Draft Beer Beverage Dispenser

missouri restaurant equipment repairAmerican Services restaurant equipment installation near Edwardsville knows that if you run an establishment that serves cold draft beer, there are some choices in the type of machine you can purchase.  You always want to make sure that the dispensing system you choose matches the type of restaurant that you run and fits in with the work load that you want to have.

The first system owners should take a look at is the direct draw system, which is the simplest and one of the most common systems out there.  This system uses a tube to draw the beer from the keg that is in close proximity to the dispensing unit.  The system is pressurized with CO2 and it allows the beer to be dispensed easily and simply.  While it is simple, there are some inherent problems with this type of draw.  One issue is that the keg can be cumbersome to move especially if the space is tight.  Another issue is the space itself to keep a keg, especially right at the bar or underneath it,  where space can be at a premium and having employees maneuver in tight quarters isn’t always ideal.

An air cooled system is another option and allows owners a little more flexibility as far as space is concerned.  Since this system is air cooled a greater length of tubing can be used, thus giving owners the option of storage further away from the dispensing unit.  This system uses ducting to house the dispensing tubes and uses a large fan to keep the lines cool.

The final system to look at is the Glycol cooled system.  This system uses propylene glycol that is recirculated through tubing in order to maintain a consistent temperature.  In these types of systems a mixture of CO2 and Nitrogen are used in order to keep the beer properly carbonated but also to move the beer through the tubing.

All of these systems have pluses and minuses and a lot of the choice is dependent on the space that is available and how much money is budgeted for the system.  The important thing to remember is to choose a good quality system that fits your space because serving stale, warm or overly carbonated beer is a surefire way to send your customers packing.
