FPSC Stirling Cooler – RIGID HVAC
FPSC-Free Piston Stirling Cooler (-160℃)
Medical field, Bio-science, Laboratory, semiconductor manufacturing, etc. Green power Stirling cryocooler brings us the cutting edge technology in ultra-low temperature applications.
RIGID Stirling Cryocooler
This is the Stirling Cooler, which we refer to as the FPSC. We’ve prepared a product lineup of Stirling coolers that can cool to minutes 120℃ using helium gas as the refrigerant. Stirling cooler which differs from a compressor, is a cooling system that continuously repeats gas compression and adiabatic expansion and uses naturally occurring helium gas as the refrigerant. Helium is a very safe gas that is entirely harmless to our global environment. The typical use of Stirling Cooler is in refrigerators, but we are also developing a product lineup for us in laboratory equipment and in equipment used for low temperature distribution of goods.
The RIGID company FPSC is hermetically sealed in a stainless steel casing. The helium gas is repeatedly compressed and adiabatically expanded as two pistons reciprocate 80 time per second in one cylinder. As this occurs the tip or heating absorbing area is cooled when a heat exchanger is installed on this heat absorbing ares. The item targeted for cooling can be cooled, and the temperature of the heat absorbing area can be lowered from – 53 to- 120 in just few minutes.

Stirling Cryocooler Models
A lineup of RIGID company Stirling cooler models include RS40 (40 watt), RS80 (80 watt) and RS100 (100 watt) models is available to meet a variety of application needs.
The standout feature of the RIGID Stirling Cooler lies in its ability to effortlessly create ultra-low temperatures of -100 degrees Celsius or even lower, a task often challenging for conventional compressor-type products. Astonishingly, it takes just 8 minutes to reach an impressive temperature of -120℃ after turning on the switch, showcasing its remarkable efficiency.
One of the striking advantages of the Stirling Cooler is its simplicity in design, resulting in a main body that weighs merely 1.7kg. This weight is only 1/5th of what conventional compressor cooling systems typically weigh, making it much more manageable and portable.

Summarize
RIGID company Stirling coolers represent the prevalent modern application of the Stirling cycle. In a typical Stirling engine, external heat is applied to a cylinder, and the expansion and compression of air or gas inside the engine drive a power piston. A lightweight “displacer” piston precedes the power piston, shuttling the air or gas between the hot and cold ends of the cylinder.
However, in a Stirling cooler, the cycle operates in reverse. An external power source, like an electric motor, compels the power piston to move ahead of the displacer. This reversal leads to gas compression and expansion within the cylinder, without any phase changes or liquid refrigerants involved.
Modern “free piston” Stirling coolers, like the one demonstrated in the video, use helium pressurized at approximately 400 psi and operate at a rate of about 60 cycles per second. These free piston Stirling engines/coolers were invented by William Beale of Ohio in the 1960s and are designed to operate at exceptionally high speeds without the need for linkages, lubrication, or frequent maintenance.
The specific 100-watt Stirling cooler – model RS100, showcased in the picture is a product of the RIGID company. These Stirling coolers are increasingly finding applications in various fields, including medicine, laboratory research, space exploration, defense, and scientific investigations. Their reliable and efficient cooling capabilities make them highly valuable assets in modern technology and research advancements.
