  • Electric Vehicle Battery Cooling

    Electric Vehicle Lithium-ion Battery Cooling

    Superior Lithium Battery Cooling Solutions
    RIGID has developed a compact liquid chiller to satisfy the growing market segment of customers who want to microclimate cooling systems but can handle the coolant circuitry.
    Here we introduce you to the Best Electric Vehicle Battery Cooling System – Plate Liquid Chiller. It is designed to circulate chilled water or liquid throughout the tubing to get optimal local cooling performance. The mini and mobile liquid chiller is a circulatory cooling subsystem. Effective cold plate design typically leads to a higher pressure drop across the battery pack due to the long length and narrow coolant channels required. The application is to provide chilled glycol/water to a cooling system for a battery pack in an electric driveline vehicle.

    Medical Device and Chemotherapy Cooling

    Medical Device and Chemotherapy Cooling

    Scalp hypothermia is cooling the scalp with ice packs or cooling caps (cold caps) for a period of time before, during, and after each chemotherapy treatment to try to prevent or reduce hair loss.
    RIGID patent compact Plate Chillers are specially designed for hospital and medical devices and chemotherapy machines. They are temperature-control devices for cooling and thermal energy requirements. It moves energy in the form of heat by compressing a gas known as a "refrigerant," then pumping it through a system of coils and using the air around the coils to heat and cool spaces. It is an ideal small and portable cooling module for medical devices.

    Medical Lab Equipments

    Medical Lab Equipments Cooling

    RIGID Coaxial Chiller provides micro cooling solutions for world-leading manufacturers of laboratory and biopharma equipment. Plus, we also offer tailored compact refrigeration solutions that fit the needs of laboratories and medical & aesthetic devices.
    With our sophisticated engineers and technicians, RIGID contributes to meet the challenges of the 21st century by continuously innovating our products to support medical and lab small cooling requirements.

    Cryotherapy and Heat Therapy

    Cryotherapy and Heat Therapy

    RIGID 24V Liquid Cooler (LC3220E-H) is a perfect match for human body heat and cool, as well as water-cooled dog beds or mats! Hot summers are not comfortable for our pets. As one professional compact and mobile cooling solution provider, RIGID has tried different products and solutions, we found in the market they are all water and icy mixture, complicated and time-consuming, plus their performance isn't cooler than the concrete floor. So we invented a 24V compact cooler to provide 24/7 continuously chilled water. You only need to connect it to a pet's mat and dc power supply, then it works!
    LC3220E-H also can be applied to electronics and instrument cooling and thermal management.

    Hydrotherapy Treatment  Cryo Chill

    Hydrotherapy Treatment

    Cryo Chill

    Hydrotherapy, formerly called hydropathy and called water cure, is a part of alternative medicine (particularly naturopathy), occupational therapy, and physiotherapy, which involves water for pain relief and treatment. Hydrotherapy is the use of water, both internally and externally and at varying temperatures, for health purposes. Also known as water therapy or "water cures," hydrotherapy includes such treatments as saunas, steam baths, foot baths, contrast therapy, sitz baths, and colonic cleansing.
    RIGID Refrigeration Condensing Units (115V-60Hz; 220V-50Hz) are being used in a pain relief treatment that is increasingly being administered in athletes' clubs and hospitals.

    Vertical Smart Farming

    Vertical Smart Farming

    Chillers are vital to successful hydroponic growth because they keep the nutrient solution in the ideal temperature range. Active Aqua Chillers from Hydrofarm make it easy to maintain the perfect temperature in your hydroponic reservoir, which will help ensure that you bring in big, healthy harvests!
    RIGID 24V Coaxial Chiller DV3220E-C is specially designed for home farming and Small & Smart Hydroponic Farming. When the reservoir in a hydroponic system has an ideal solution temperature, the plants' roots are the first to notice. Cool solution temperature means more dissolved oxygen, which is great for creating healthy roots and, in turn, a bountiful harvest. Vertical farming is environmentally friendly and is getting popular recently.

    Medical & Aesthetic Device Cooling

    Medical & Aesthetic Device Cooling

    The demand for medical equipment cooling is expected to witness a continuous increase from the medical industry. Medical cooling systems are used to reduce the heat load generated by medical equipment during diagnostic procedures. By doing this, the medical cooling systems are able to maintain the life cycle of imaging equipment and help to achieve the goal of quality patient care.
    RIGID active thermal management is used in various applications such as patient core temperature management, skin cooling, medical device cooling, and laboratory equipment cooling. Medical equipment often needs internal cooling systems. MRI machines, X-ray machines, and home health air supplies all require some combination of air conditioning, refrigeration, and humidification or dehumidification.
