Operation under pressure using water up to 200 °C.

In the case when a relatively large amount of heat passes through a small cooling area, water, in comparison with an oil coolant, has a significant advantage. In order that, with the same average temperature difference between the wall of the mold and the medium, a constant amount of heat can be transferred when using an oil coolant compared to water, a 4-5 times larger cooling surface is needed, i.e. the number of cooling holes. Just with small molds, this is often impossible to implement in practice. The use of water as a coolant has such an advantage in the future that the amount of pumping compared to an oil coolant can be reduced by 2-3 times.

GWK heated water thermostats of the eco wh model range are designed for special use in the temperature range up to 200 °C. Pumps with magnetic connection, control and limitation of recirculation temperature, built-in condensing device, prevention of evaporation, level control is provided by means of a built-in high-pressure recharge device and a serial step-by-step temperature change function for strong heating of the mold at the end of the technological process in a gentle mode and guarantees high reliability of production. Modular design heaters and cooling systems make possible a specific application for any task.
