Heating Circulator(Temperature range RT+5~250℃)
SY series Heating Circulator heat liquids effectively at working temperatures between RT+5 °C to +250 °C for chemical industry, petrochemical industry, laboratory research,

Introduction
This Heating Circulator is a water-cooled type heating circulator. The bath fluid is heated up by electricity and transferred to reactors by circulating pump, which can be applied to pharmaceutical plants, chemical industry, petrochemical industry, laboratory research, etc.
Main Features
1. Designed with exhaust valve, which makes it easy and smooth when filling in bath fluid.
2. Using oil as bath fluid will extend the service life of circulator.
3. Over-temperature alarm, overload protection, over-current protection.
4. Intelligent PID control with high precision.
5.Bath fluid tank is made of anti-corrosive stainless steel.
6.Heating bath fluid circulates in a closed system, which extends its service time.
7.Tap water cooling design can down the high temperature bath fluid rapidly.
