ETK Immersion Coolers

Cooling using the LAUDA immersion cooler ETK 30

LAUDA through-flow coolers and immersion coolers are used as add-on devices to cool heating thermostats or any type of bath below ambient temperature. The preferred use of through-flow coolers is the use in conjunction with heating thermostats and integration into the cooling circuit. LAUDA immersion coolers provide a quick way to extend the temperature range downwards when used in conjunction with heating thermostats, water baths and cooling traps. The thermostats work on the classical principle of direct evaporation, and the flexible hose connection means that they can be used without any problems. The ETK 50 even has adjustable temperature control.
