Product Description

Thermal oil heater is designed for process temperature control up to 350℃, which is custom designed for each application, using synthetic heat transfer fluids. TOH series is the most compact temperature control system. The system include an electric heater, centrifugal pump, expansion tank, control panel, strainer, stop valves, platinum resistance thermometer sensor, pressure gauge with electric contact, alumina silicate fibre insulation and connecting piping mounted in a welded steel frame.

Normally a pump transports the thermal oil into the heater, which is then heated. The thermal oil will then flow out of the heater at a fixed flow rate decided. The heat generated is evenly distributed and the efficiency of the heater is high. Temperature sensors can be used with control to achieve the desired temperature range.

The heater could come with a shell and tube cooling exchanger and valves for processes that require heating AND cooling.

► APPLICATIONS

• Reactor,  Distillation still, etc.

► SAFETY PROTECTION

• Over Temperature Alarm, Automatic Interlock Protection
• Pressure Detection: pressure gauge with electric contact which show real pressure of entire system was equipped on the piping. Control system will alarm immediately when pressure below a certain value, meanwhile the Heater stop too.
• Oil Low Level Detection: Expansion tank is equipment with a ball float level controller, Control system will alarm immediately when pressure below a certain value, meanwhile the Heater stop too.
