These Zhengzhou Greatwall SY series High Temperature Circulator is liquid circulating equipment which adopts electricity to heat, and provides high temperature circulation liquid. It is widely applied to heat reactors in pharmacy, chemical industry, petrochemical and other industrials.

Features of SY-50-250 High Temperature Circulator:

1. Over-temperature alarm protection;
2. PID control has high temperature control accuracy;
3. The circulation pump can output the heat transfer liquid inside the equipment to heat other equipments outside;
4. This system has vent valve which is convenient to add liquid into the system;
5. The circulation system adopts stainless steel material which can prevent corrosion, rust and high-temperature liquid pullution;
6. The circulation system is totally-enclosed type, so the service life of the heat transfer liquid will be much longer;
7. It can work continuously.
