E Series industrial

immersion coolers

Cooling capacity 1.7 kW to 115 kW

Standard immersion / submerged recirculating chiller
for suspension in an on-site tank

The high-performance air- or water-cooled immersion chillers of the E Series not only increase productivity, but also reduce manufacturing costs. By means of an immersion cooler, the heat energy from production or process systems is removed from the system by an immersion cooler placed in the coolant tank.

Immersion cooling units have an extremely high efficiency and ensure constant temperatures of the coolants.

Individually configurable and expandable according to customer specifications.

Circulating media

Water Emulsion Oil

Flow temperature range

10 – 40 °C

Quality and performance features of E Series immersion coolers

Wide range of options due to flexible modular principle
Individual and application-specific configuration optimised for the most diverse customer requirements, e.g. multi-circuit systems, high ambient temperatures, special voltage etc.
High precision control
Automatic power adjustment
Standard temperature stability +/- 1 K
On request, flexible control and temperature precision with ACC precision control
Completely factory-assembled refrigeration circuit with all necessary refrigeration and safety components as well as with complete oil and refrigerant charge (CFC-free)
Stainless steel evaporator specially adapted to the application
Immersion part completely made of stainless steel
