Oil Temperature Control Units
TT-407 Z
This 8kW heating and cooling unit is for use with temperatures between - 20°C to 240°C with a heat transfer liquid.
This 8kW heating and cooling unit is for use with temperatures between - 20°C to 240°C with a heat transfer liquid.
It is designed for use with double walled vessels and reactors and it has a two-circuit cooling system for operations below zero degrees.
• Self-optimizing temperature controller with digital display of the set and actual temperature. With high precision regulation in 1/10° range; can be adjusted to read °C or °F.
• Automatic temperature control – difference between set and actual temperature activates an alarm.
• Lime scale free heat exchanger.
• Digital flow indication with control of the minimum flow.
• All components in contact with water are made from corrosion resistant stainless steel.
• Heating with automatic cascade connection.
• Leak free high temperature pump with axial face.
The pressure is displayed by manometer.
• Hot oil circuit with by-pass, which ensures internal circulation if valves are closed.
• No oil cracking because of special construction of the heating elements.
