RENOLIN THERM 320

RENOLIN THERM 320 is a high-performance heat transfer fluid based on selected, highly refined mineral oils for use in the liquid phase in closed heat transfer systems with forced circulation. RENOLIN THERM 320 (heat transfer oil Q DIN 51 522) can be used over the entire working range without pressure overlap.

Application

RENOLIN THERM 320 is optimally suited for use in the indirect heating of reactors, polymerization and distillation systems, processing machines and driers, as well as heat exchangers in processing systems, and in systems for heat recovery. The heat transfer fluid is best used at temperatures ranging from 200 °C to 300 °C. The upper limit for use is an inlet temperature of 300 °C. The film temperature should not exceed 320 °C.

Specifications

Heat transfer fluid Q according to DIN 51 522.
