Nowadays, many engineers are facing the biggest challenges of compact and precise thermal management. Conventional scroll compressor is too big which isn't suitable for small device and personal use. In the industry of compact and mobile refrigeration, there are no logical bits and bytes, nor industry qualification standards.


    AlphaCooler is RIGID 2 years ground-breaking research and invention fruit. It has a 40 dB(A) noise level at the high flow rate, which our customers are pretty satisfied with. More important thing is, no more ice, no time limits. It works continously 24/7. 250ml 26C deg water chilled down to 4C deg takes only 6 minutes. Now it has also been transferred to market for further development and commercialisation. They have also been covered in trade magazines. .


    For the past 10 years, Rigid Technology has stood the test of time for the highest level of performance, quality, safety and innovation. We have built a comprehensive knowledge base in compact and portable thermal managements, enabling us to provide customers with complete solutions. Besides standard small cooling units, RIGID accepts customized order and OEM production.


    If a change in physical dimensions, temperature requirements etc. is required for your application, RIGID specializes in volume manufacturing of refrigeration system tailored to your application. Feel free to contact ann@rigidhvac.com about your requirements, we will get back to you in 12hrs.

  • AlphaCooler - Creating Maximum Efficiency With Minimal Power Requirement

    The compact AlphaCooler works by pumping chilled fluid through a heat-transfer garment lined with a network of tubing, typically made from polyvinyl chloride. Metabolic heat is transferred to the circulating liquid, which is pumped back to a cooling unit where the heat is rejected. Since conduction is the primary mode of heat transfer in this type of system, the PCS garment should fit snugly in order to increase the skin-to-tubing contact area.


    The coolant fluid is chilled in the cooling unit, using more powerful vapor compression system (7 times cooling capacity more than thermoelectric cooling) and re-circulated back to the heat-transfer garment to continuously cool the user. The cooling unit must be located external to the user’s uniform since heat must be released to the ambient environment. The temperature of the liquid for the vapor compression system can be controlled by the user by varying the speed of the compressor.


    AlphaCooler is able to run on battery, DC power, car power, solar or an electrical outlet. AlphaCooler is able to maintain core body within +/- 14C deg for as long as desired.
