autotherm temperature control unit AT: High-precision temperature control of thermal oils
Working principle
autotherm temperature control units use high-performance pumps to supply closed, semi-open and open consumer systems with thermal oil that maintains the specified temperature.
Heating is mainly electric, but hot water or steam can also be used. Cooling is achieved using cooling water, which extracts energy as required in heat exchangers.
All system elements necessary for operation are integrated into a single assembly and coordinated with each other to meet the highest requirements for control accuracy and dynamics.
