Heat recovery from cooling water of injection molds

No pre-filter necessary

FERCHER wastewater heat exchangers are highly dirt-resistant and can be operated without pre-filters in most cases, even for wastewater with a high dirt load such as plastic particles.

Can be installed indoors and outdoors

The heat exchanger can be installed both indoors and outdoors. For outdoor installation, only the intermediate medium needs to be frost-proof. If the wastewater side freezes, e.g., due to a production shutdown in winter, this poses no problem for the heat exchanger.

Use of thermal energy

If the production process has no need for warm water, the heat can be used to heat the factory facilities/offices or nearby buildings.

Due to the open, pressureless design on the wastewater side, the heat exchanger can be viewed at any time, even during operation, and can be cleaned if necessary (although this is not necessary in case of normal operation).

In summer operation, the waste heat from the machine cooling water can be used to preheat the boiler feed water. In winter operation, the company's production halls can also be heated, for example, by simply preheating the return flow of the heating water. Integrating the heat into existing systems is very easy.

Applications of this size can reach heat-transfer-powers in the Megawatt range and have a mean Return on Investment of approximately 1 to 2 years.
