A: Take a look at the list of factors below. The more that any of these factors increase in your facility or business, the shorter your payback period, and the greater your savings. You should consider a Freeaire® All Climate™ system if you have some of these things:
- Higher electrical rates for energy and demand
- A cooler of at least 500 cubic feet
- Equipment such as evaporator fans, door heaters, compressors, condensing fans
- High amperages, voltages, or power factors for your equipment
- Long runtimes for your equipment
- Utility incentive programs
You should consider a Polar Power™ package to your system if you also have:
- Outside temperatures often colder than your refrigerated space
- A higher temperature to maintain (more hours per year of outside air use)
- Shorter distance to and from the outside of your facility
- Easier walls to cut through to the outside (masonry is the hardest)
Q: My city’s air is polluted. How can I refrigerate with that?
A: Every Polar Power package comes standard with a high-capacity MIRV 8 pleated filter. For dirty outside air, or even loading dock exhaust, you can add a carbon filter for further filtration and odor removal of incoming air.
Q: How much money can I save?
A: While every installation is different, every Freeaire installation can mean significant cost reductions. Please call us for more detailed information.
Q: Why does Freeaire cost so much?
A: Ultimately, a Freeaire system doesn’t cost more. It saves more. After an initial up-front investment and a short payback period (often as low as 2 years), you’ll realize savings dividends for years to come. Freeaire provides the most technologically advanced refrigeration system of its kind. From our Permanent Split Capacitor (PSC) and Electronically Commutated (ECM) motors, to the sophisticated Cooler Controller™, we use the highest quality components to ensure years of effective, reliable, energy-efficient, low-cost refrigeration. Simply put, you’ll find no greater cost-cutting strategy in cooling technology.
A: They may be, and the list of efficiency utilities offering prescriptive rebates to offset the installation costs of Freeaire systems gets longer all the time.
Q: What about freezers?
A: Freezers can save even more with Freeaire!
The poorer efficiency of the typical freezer’s condensing unit means that your savings can be even greater. A typical freezer stops refrigeration about every six hours to defrost the evaporator coils. Large-wattage electric defrost heaters stay on for a fixed-length cycle several times a day, regardless of actual need. But the Freeaire‘s on-demand defrost cycle runs only as long as there is ice to be melted from the evaporator coils, and no longer. This saves much of the energy needed to run the defrost heaters as well as the wasted energy that would have been consumed by the condensing unit to remove the unwanted heat.
Q: You don’t really stop the evaporator fans, do you? My refrigeration serviceperson says that you should never do that.
A: Yes, we do!
Your serviceperson knows how much trouble can be caused by evaporator fans that don’t operate when needed. Conventional cooling systems take the easy way out, by simply making sure that even energy-inefficient evaporator fans are never switched off.
The Freeaire Cooler Controller makes sure that the evaporator fans are always on when needed, but never on when they aren’t. Instead of using evaporator fans as high-priced, electricity-guzzling air circulators, the Cooler Controller assigns this task to Circ™circulating fans, using a tiny fraction of the energy needed by evaporator fans. This ensures proper refrigeration with minimal energy use and demands on your equipment.
Q: How can a Freeaire system help me when it isn’t cold outside?
A: Even in warmer climates and warmer seasons, Freeaire can save you money. The fact is, conventional cooling technology is full of waste and inefficiency. No one has eliminated every ounce of waste from refrigeration, until now.
Freeaire saves you money by operating the various components of your refrigeration equipment only as much as truly needed.
Conventional systems run costly, inefficient evaporator fans at all times – an unnecessary use of equipment and energy. Freeaire’s Cooler Controller runs them only when the compressor is operating, and during on-demand defrost periods. When only air circulation is called for, you’ll save by using energy-efficient Circ™ fans. And here’s more savings: your condensing unit will operate less because of the reduced heat load from the now-silent evaporator fans. And reach-in door heaters don’t need to operate when the humidity is low, resulting in even greater savings.
