Heat exchanger
Our heat exchangers are ideal for cold and cooling water applications and are used in particular in plants where cooling water networks are available.
The units extract heat from the oil and transfer it to the cooling water or cold water. This water can be collected by the operator at a central point and disposed of in a targeted manner. This makes it possible to efficiently use the generated heat for other purposes, such as heating domestic water.
With this solution, we help our customers to optimize their energy balance whilst also increasing the efficiency of their systems. The targeted use of process heat ensures that energy is not wasted but put to good use, offering a clear benefit for both the environment and operating costs.
A BIT OF COOLING TECHNOLOGY KNOW-HOW
Explanations and clarifications on some frequently asked questions about cooling technology and terminology used.
HOFFMANN coolers are designed as compression refrigeration systems. This version which can also be found in refrigerators, for example, has the best efficiency of all common cooling techniques in the room temperature range.
According to DIN EN 378-1, the working medium is a "fluid used for heat transfer in a refrigeration system which absorbs heat at low temperature and low pressure and releases heat at higher temperature and pressure, with changes in the state of the fluid usually taking place."
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.
