Automotive Material & Coolant Monitoring System

In the automotive industry, temperature control is mainly used in inspection benches and material testing. Most parts are tested under extreme temperature changes to ensure normal operation and reliability in use before they can be put into practical use. Simulating extreme ambient temperatures in a very wide temperature range is an important part of material testing.

Coolant is a vital part of the engine cooling system. With the continuous improvement of engine design, the cooling system must be better than before to prevent the system from malfunctioning. It is important to monitor the use of coolant additives and ensure that the cooling system is operating correctly. Due to the extreme temperature, the coolant may often be contaminated, the coolant is diluted, mixed and oxidized.

Touch screen digital display, the device is equipped with a communication interface, all data can be exported by U disk; the liquid filling indicator clearly shows the location of the heat transfer medium.

Emerson Copeland / Danfoss scroll flexible compressors, all refrigeration controls are international brands, high temperature control accuracy, fast cooling speed

Multi-channel temperature and flow control, one device can realize multi-channel output, and each channel can control different flow;
The device can choose not only to control the flow, but also to control the pressure;
At the same time, it is equipped with a powerful circulation pump to ensure the delivery of high-viscosity liquids and can provide high flow rates under stable pressure
