KRA Cabinet condensing units are designed for used in direct expansion refrigeration and freezer systems, such as cockpit freezers/refrigerators or catch-box chillers (not holdover plate systems), and can also be used with built-in galley freezer/refrigerators. KRA units work in conjunction with evaporator plates installed in an insulated box, or a box wrapped with evaporator tubing. Box temperatures between -5° F and 40° F (-20° C and 5° C) can be achieved with the proper application.
KRA condensing units are housed in an attractive white aluminum enclosure, which can be mounted on a vertical bulkhead or a horizontal shelf. An integral drain pan allows any condensate to be routed to the bilge or sump.
Units are available with 1/4, 3/8, and 1/2 HP compressors, and 115V 50/60Hz or 220V 50Hz. All KRAs have a durable cupronickel water-cooled condenser. Units are available in two condenser configurations: Air/water-cooled or water-cooled only. This dual configuration will ensure that the unit performs efficiently in hot engine rooms, while also allowing full air-cooled operation when no cooling water is available.
New Low-Profile Models
The water-cooled-only models are available in a new, compact, low-profile design. At 11" (280mm) tall, these units are 4.75" (121mm) shorter and 10 pounds (4.5kg) lighter than before. In addition, the re-configuration of the terminal strip and additional access covers enable easier installation and maintenance.
