• Cold & Hot Therapy and Body Cooling for Athletes,

    Medical & Aesthetic Device.

    RIGID develops and custom made compact cooling units for an athlete's body recovery. The cooling unit is ultra-compact and lightweight, which is very easily integrate into your device. It circulates chilled water around all lower-body muscles while keeping you perfectly dry. Immediately upon wearing the pants and starting session, your skin temperature will drop to the optimal recovery range of 4ºC-20ºC. It can provide 24/7 continuous cooling for an athlete's body recovery after sports. No Ice, No Hassel.

    Cold & Hot Therapy and Body Cooling for Athletes and Patients Recovery

    Cold therapy reduces the negative effects of tissue damage on the Athlete and Patient. A bunch of lab reports shows that cryocompression can enhance recovery and performance following a heavy resistance exercise workout, especially good for Muscle damage, physical performance, strength training, fatigue, resilience.

    Recovery from exercise is an important factor in the performance of successful resistance exercise training programs. Thus, there was a need for athletes to take cryocompression technologies that may assist in the recovery from exercise and allow for better day-to-day training performances and therefore improve the effectiveness of the training program.

    RIGID custom mini cooling unit connects to, a reservoir, a water pump, and a customer's control unit and a garment with flow channels to circulate cooled water (10C) across the surface area of the legs and buttocks and to provide compression.


    Key points


    • The combination of circulatory cooling and compression technology enhances recovery from heavy resistance exercise.
    • Sleep quality is enhanced following the use of cyo-compression when compared to typical no-intervention control conditions following heavy resistance exercise.
    • Muscle damage markers, pain and soreness mark-ers are improved with cryocompression when compared to no interventional control conditions following heavy resistance exercise.
    • Recover faster – sequential compression to boost circulation, improve lymphatic function, release muscle tension, increase mobility and eliminate soreness.

    Liquid Chiller Series

    Small Refrigeration Systems for Chilling Liquid

    RIGID has developed the compact liquid chillers to satisfy the growing market segment of customers who want to microclimate cooling
    systems, but can handle the coolant circuitry and the system controls.

    RIGID liquid chiller is a circulatory cooling subsystem. It consists of a mini compressor (12V/24V/48V) with R134A coolant, the smallest
    condenser and radiator, copper coil evaporator (heat exchanger), filter drier, driver board and other refrigeration parts.

    The performance of the liquid chiller depends on the major components (compressor, heat exchangers, coolant). RIGID standard liquid chiller
    offers 100W~550 W of capacity and can operate in ambient environments as warm as 50°C.

    RIGID liquid chiller is a kind of heat transfer system. Its benefits include ultra-small radiator and high heat flux, it provides excellent
    cooling performance. The compact chiller is good for customers who are able to deal with system control. If you want a cooling subsystem
    module only to integrate or assemble with your machine or equipment, Rigid small chillers are better choices.

    We provide the drive board together accordingly. User’s control board can connect with our DC compressor drive board (included) to control
    compressor speed and get the best performance they needed.
