Project Description

98Water Temperature Control Unit

— LRD Series

About the unit

The water temperature controller LRD series is designed to work with a wide range of high temperature application up to 98 ºC, which are used for controlled heating of products, mechanisms and factory machinery in a wide range of industries, including chemical reaction and casting industry etc.

High temperature water from the mould is returned to the unit and pressurized by high-pressure pump, sent to the heating tank and finally to the mould with a constant temperature.
