Free-cooler modules are heat exchangers equiped with a fan which are connected in series with the cooler. Installed outside the manufacturing hall. With respectively low ambient temperatures they release part of the heat being diverted into the ambient air. This unburdens the cooler and thus saves energy. If heat cannot be released to the area due to high ambient temperatures, the cooler must divert all of the excess heat.
For safety reasons, free-cooler modules are only operated with water.
Explanations and clarifications of some frequently asked questions and terms used in refrigeration technology.
The function of a cooling lubricant is to reduce the friction between tool and workpiece in order to generate less heat and thus improve the machining result.
In this design, the evaporator is designed as a cooling coil. The cooling coil dips directly into the liquid to be cooled.
If the heat is not to be released into the workshop, the condenser may be installed outside the workshop (e.g., on the roof).
