Project Description

330℃ Thermal Oil Temperature Control Unit

— LDDC/LDDM Series

About the unit

The oil temperature controller LDDC/LDDM series is designed to work with a wide range of high temperature application up to 330 ºC, which are used for controlled heating of products, mechanisms and factory machinery in a wide range of industries, including chemical reaction,casting and machineries industry etc.

High temperature oil from the mould is returned to the cooling tank and cooled by indirect cooling. It is the pressurized by the high-pressure pump, sent to the heating tank and finally to the mould with a constant temperature.
