Both versions can be used for temperatures ranging from -40⁰C to +40⁰C and are suitable for synthetic and natural refrigerants. The CDK model has a capacity range from 7.33kw up to 145.3kw (SC2), while the CDL version, with stainless steel tubes, offers a range from 8.9kw to 154kw. The fans are mounted to the outside of the cooler and operate at the optimal speed required for large production and working areas. They come as standard, not wired to a junction box. However wiring is available at an additional cost, if required. A comprehensive range of variants and accessories allow for a high level of customization. Thanks to standard hinged end covers and optional hinged drip trays and fans the air cooler is quick and easy to clean.The suspension brackets for the range are designed to allow the air cooler to be mounted either flush to the ceiling or with a 20mm clearance for deep freeze areas. This gap provides an insulating air cushion. When mounted in the center of the room, or between suspension rails, the CDK/CDL cooler provides the optimum circulation of cool air.
