Immersion cooler ERK

Immersion cooler ERK

HOFFMANN Immersion Coolers ERK are entry level models for cooling all kinds of pre-filtered and slightly soiled fluids. They are mounted on a cooling lubricant tank, with no need for additional space. The Immersion Coolers are comprised of a housing and a stainless steel tube-coil evaporator (1.4301) underneath, which is immersed into the fluid to be cooled. The evaporator is low maintenance and easy to clean.

A circulation pump is standard with all immersion coolers allowing better heat transfer. Waste heat is vented into ambient air via an air-cooled condenser. The coolant temperature is adjustable, with accuracies of ± 1°C. Standard HOFFMANN Immersion Coolers are designed for ambient temperatures of up to + 40°C.
