Industrial cooling and heating

DELTATHERM Hirmer GmbH Industrial cooling and heating
Central cooling systems

Immersion chiller for water, oil or emulsion

Standard immersion / submerged recirculating chiller Series E for suspension in an on-site tank Cooling capacities from 1,7 kW to 115 kW Efficient immersion coolers from DELTATHERM 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. 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 - Complete electrical control cabinet with all necessary control and monitoring equipment, - completely wired with digital temperature controller - Easy integration into the production layout due to individual colour selection - Stable profile frame construction with easily removable cover plates - Maintenance-friendly arrangement of all components Main application: coolant filtration The emulsions and oils in cooling lubricant filtrations, which are often heavily contaminated, are kept at a precise temperature and cooled by DELTATHERM® immersion coolers.

Main applications of DELTATHERM® continuous-flow coolers


The high-performance DELTATHERM® compact refrigeration units of the DK Series ensure precise temperature control of tanks in filtration processes, among others, but also in the plastics industry. Continuous-flow coolers are used wherever tanks or containers heat up during operation.

Excess heat from production or process systems is removed from the system by targeted cooling with cold water.
