While there are a number of conditions that affect the amount saved by Frigitek in any particular installation, typical energy and cost savings are in the 25-35% range.

The Frigitek will not contribute to any tendency for the evaporator coils to ice up. Because it operates the fans at high speed whenever the system is in cooling mode, the evaporator heat transfer characteristics are unchanged. In fact, the Frigitek has an Ice Sensor feature, which will continue to operate the fans at high speed if ice is detected in the coils.

Extensive testing, and actual customer experience, verify that there is more than adequate air movement to prevent stratification with the fans running at low speed under Frigitek control.

For certain applications, other benefits can equal or exceed that of energy savings. The reduced air movement extends the shelf life of perishables such as meat, fish, produce, pizza dough, and flowers, by slowing the dehydration process. In addition, the reduced running of the compressor will add to its lifetime, putting off the day that this expensive unit will need to be replaced.  And, in large industrial warehouses, the reduced fan noise contributes to a safe work environment.

The Frigitek should outlast your refrigeration system. Properly installed, there is no reason for it to fail under normal operation.
 

Installation time is typically about 45 minutes to one hour for Single-Phase systems, and may average two hours for Three-phase equipment.  Only qualified persons, familiar with electrical wiring, should do the installation of the Frigitek.
 

For installation information, see the appropriate Single-Phase or Three-Phase manual elsewhere on this website.

A five-year warranty on all Frigitek equipment is found in the back of each owner's manual.

Officially it falls under the Magnasum-Moss Act passed by congress that states manufacturers can not void warranties on their equipment when after market product are added, provided they are approved by the governing body that approves such products. If it is electrical, it must be approved by UL or ETL, which the Airco Saver is. I personally never liked saying “the government says we can do it”, so here is the analogy I always use. A standard thermostat turns an A.C. on and off based on reaching the desired set point. A PROGRAMABLE thermostat does the same thing PLUS allows you to set a time table for on and off operation, in addition to, and/or regardless of, reaching the desired set point. The Airco Saver works much the same way as a programmable thermostat but is based on the time it takes to fill the evaporator with refrigerant. These timed amounts will vary based on the hotter it is, the longer it takes fill up and get as cold as possible. The Airco Saver only intercepts the 24 volt signal from the thermostat to compressor and does not interfere with the cooling ability, or modify the mechanics of the system in any way. When the evaporator is full, the Airco Saver shuts down the compressor and allows the fan to continue to pull cold air into the plenum that feeds the ductwork. If set point is still not reached during this time, the Airco Saver releases the compressor. The temperature sensor connected to the Airco Saver makes this decision when the temperature rises by 1.25 degrees and never interferes with the thermostat function or interfere with cooling. This same question also comes up when adding our Thermamax P.R.O.A. to any hvac/r systems. It is an ASHRAE approved additive although it would not be as easily removed from the system as the Airco Saver. This is why it is mandatory to replace the filter dryer.

 According the Copeland, who manufactures more compressors than anyone, a compressor has approximately 12,000,000 (yes, million) stops and starts in a 20 year life. During this lifetime, it is not as critical how many times it starts and stops in 24 hours but rather how long it is OFF before it has to re-start. The more extreme the conditions are, the hotter the compressor will be along with high head pressure. The longer it is off, the more the pressure dissipates and cools down, making it less stressful to re-start. The attached bulletin from Copeland recommends an OFF time of at least 3 minutes for optimal life of the compressor. The Airco Saver has a built in “default” at 3 minutes and will not allow the compressor to re-start. Most new programmable thermostats now also have a built in 3 minute delay.
