  • Fast Therapy Recovery Liquid Cooler

    The 24V Liquid Cooler LC-3220E-H (heat or cold) can be applied directly to a part of the body. Both cryotherapy (cooling) and superficial heat help with pain control. Cryotherapy is used after acute injuries or surgery to decrease pain and to help reduce inflammation and swelling. If a patient has severe tissue injury, a circulating cold-compression unit may be used. This has a sleeve that is wrapped around the affected area to compress it while distilled water (sometimes glycol mixture) is circulated within the sleeve.


    No Ice

    Therapeutic cooling technology without ice, easy handling.


    Fast & Safe

    Not invasive, not aggressive, contact with undamaged skin.



    Advanced technology of real-time temperature parameters.



    It allows cold/hot on the areas to be treated and allows to optimize the therapy where you need.

  • Liquid Cooling Application Examples

    Dogs and other animals are benefited from cold liquid therapy, but the most dramatic improvements are seen in people who normally operate in a heat-stress environment. This involves the military, surgeons, firefighters, construction workers, oil and gas workers, and professional athletes.
