Globaltherm HT350

Globaltherm HT350

PRODUCT DESCRIPTION

A superior synthetic heat transfer fluid that delivers outstanding performance and thermal stability at continuously high operating temperatures. With low vapour pressure, high thermal conductivity and oxidation stability, Globaltherm HT350 Heat transfer fluid offers excellent heat transfer properties over extended periods operating at temperatures up to 350 °C. Maximum heat transmission to the process vessel or equipment will allow the use of smaller circulating system pumps, valves and heating coils.

NOTE: When draining hot fluid a†er flUSHING, normal safety PRECAUTIONS SHOULD be taken to prevent BURNS and the RISK of fire.

APPLICATIONS

Globaltherm HT350 Heat transfer fluid is recommended for use in non-pressurized, indirectly heated, closed loop, liquid phase heat transfer systems operating at bulk fluid temperatures up to 350°C. The maximum recommended film temperature is 375°C. Globaltherm HT350 Heat transfer fluid has low toxicity

SERVICE CONSIDERATIONS

As with any heat transfer oil, certain precautions should be taken to ensure satisfactory performance of Globaltherm HT350

Heat transfer fluid in service:

• Before full temperature is imposed, all air and water should be completely vented;
• Hot oil is rapidly oxidised by air, causing thickening and deposit formation. At places where the oil is in contact with the atmosphere (e.g., the expansion vessel) oil should not exceed 70°C for prolonged times or the oil needs to be blanketed with inert gas. Copper and its alloys promote rapid oil degradation in the presence of air and need to be avoided at these places; and,
• Hot oil circulating pumps must be checked frequently to prevent air from entering.

An analytical routine check of the heat transfer medium, while it is hot and circulating, should be part of the routine maintenance plan. This check should be carried out at least once a year, preferably three to four times a year. Testing can be carried out by Global Heat Transfer lifecycle management programme - to all users of Globaltherm Lube Private limited. The thermal fluid parameters which are measured will allow our experts an accurate assessment of the condition of the fluid. This way, of testing and analysis programmes ensure prolonged and trouble-free operation of the fluid. Changes to the condition of the fluid are quickly detected and managed and can be avoided in time before more extensive damage (to both system and fluid) and further costs are incurred.

COMPATIBILITY

While unused GlobalthermHT350 Heat transfer fluid is compatible with most organic and synthetic heat transfer oils prior laboratory testing is recommended before topping-up the system with this product. Adding Globaltherm HT350 Heat transfer fluid as a top-up to used fluids may help to increase fluid life (i.e., aromatic types).
