3. Where can I buy the race car cooling suit?Cooling suit link: https://www.rigidhvac.com/store/products/heavy-duty-cooling-suit
4. What gives the AlphaCooler so much power for its size?
The AlphaCooler has one of the most powerful and efficient rotary micro-compressor in the world. Cooling power equal to a compressor 5x its size - this is the core of our cooling system.
5. What kind of liquid or coolant Formula I should use?
For longer system life, the Coolant Formula includes propylene glycol and a subtle fungicide, and distilled water as well.
6. How cold can the AlphaCooler make a person while in operation?
At 110º F (43.3 ℃) ambient, the AlphaCooler is capable of chilling to 32º F (0 ℃).
Operating temperatures are adjustable from 35º to 70º. The recommended temperature setting is 50º F (10 ℃). We recommend this mid-range temperature because studies show that temperatures below 55º can shock the capillaries just below the surface of the skin and cause them to close, actually causing your body to hold heat. 50º - 60º around the torso and vital regions of the body is most effective, cooling your body from the core.
7. How long does the AlphaCooler operate before needing to be refilled?
The AlphaCooler functions on a continuous cycle. Your driving schedule and how often you use the system affect how often you need to refill the coolant reservoir. The AlphaCooler only requires about 5 oz (145ml). of a four to one coolant formula to distilled water mixture, so we recommend topping off before every use to prevent the system from running dry.
8. What are the dimensions and weight of the AlphaCooler?
The dimensions of the AlphaCooler are 11.8" x 6.7" x 6.7" inch and it weighs less than 15lbs. (10.0 lbs empty and 5 lbs with fluid, mounting plate and pins connected)
9. How are the AlphaCooler' driver cooling suits designed?
Purchasing link: https://www.rigidhvac.com/store/products/heavy-duty-cooling-suit
The cooling suit cools: 37℉ to 70℉
One size fits most: 110lbs ~220lbs
Quick coupling connector included
Vest weights: 4.5 pounds when fully loaded with water

10. How can I control the temperature of my Alpha Cooler?
A digital display on top of the AlphaCooler communicates the current temperature. You can control or adjust your temperature through the user interface, or through a dash-mountable wired remote control that displays set temperature is also available.
11. Can the AlpaCooler cool more than one person at a time?
Depending on the ambient temperature at the time, the car and installation, the AlphaCooler is designed to run up to 2 garments at a time.
12. What are the power requirements to power a AlphaCooler?
Take 12-volt Alphacooler as an example, the power draw can spike to 20A max, depending on your surrounding temperature, the average draw is 7A-12A amps. While for 24 volts Alphacooler, the amps draw is half of 12 volts.
Tested in extreme temperatures around 120º, our system uses around 330 watts at maximum.
We highly recommend adding an inline fuse within 6 inches from the power supply, utilizing an ACC trigger wire, 1"-1.5" spacers between your cooler and floor pan for air circulation, inline fans, and NACA ducting to prevent heat soak and high amp draw. Forcing cooler ambient air to the intake of the Alphacooler can significantly affect the draw rate.13. How to keep cool in your race car with Alphacooler?
The race car cooler - Alphacooler keeps you cool and focused in extreme temperatures by pumping chilled water or glycol coolant through a specially designed cooling suit.
Powered by a rotary micro-compressor, the Alphacooler requires zero ice to operate. It is plug and play, works continuously 24/7.
We have a cooling suit with a structured vein pattern that covers a greater surface area of the body, enabling our design to have a superior heat exchange rate than any other cooling system.14. What is the cooling capacity of the Alphacooler?
