Upasani industrial cooling systems has manufactured a panel cooler which is exclusively designed closed circuit air conditioner for controlling the atmospheric temperature and humidity inside the electronic control panels and cabinets. These panel coolers are manufactured in crc sheets and adaptable to any type of cabinets for requirement of cool air to eliminate high temperatures generating inside the electronic components of higher density. These panel coolers find applications in cnc machines control box, communication equipments control box and all electronic control panels where heat sinksare to be eliminated. These coolers are available with salient features like slim design, ozone friendly refrigerants, automatic cut-out/cut-in with the digital temperature controller, noiseless working, efficient operation even at 46°c ambient, and spare parts available globally. These coolers have the advantages of avoiding ambient air contact with controls; performance of control cabinets is not affected; shut down time due to heat generation is eliminated; and eliminates noisy fans by which it deletes out any openings to ambient.
