Circulating coolers

Available with cooling capacities of up to 2000W and temperature ranges of -30°C to +40°C:
Our circulating coolers can be used throughout scientific and industrial laboratories for various cooling applications due to their universal properties. The compact, space-saving design and the very quiet cooling unit allows users to place our coolers directly on the desk in the workplace.

Circulating Cooler DLK 402

The smallest in its range. The DLK 402 circulating cooler serves as a universal cooler for the entire laboratory. A new method of casing construction provides for modern design, low weight and guarentees innovative technical features. Due in particular to the compact space-saving design with low-noise cooling unit, the freezer unit is suitable for direct use on the desk in the workplace.

Circulating cooler to 2000 watts cooling capacity

FRYKA circulating coolers are mainly used by our customers where cooling systems have so far been operated with industrial water. Some examples are the removal of process heat, stabilising of the temperature of laboratory equipment such as centrifuges, analysers, rotary evaporators or reaction vessels. All DLK circulating coolers can be used as closed or open systems.
