Semiconductor thermoelectric cooler, also known as semiconductor chiller, semiconductor temperature control console, precision semiconductor cooler, is composed of semiconductor refrigeration system, circulating water cooling system, temperature control system, and measuring fixture platform. Widely used in semiconductor industry etching devices, CMP laboratory precision devices, high-precision testing instruments, etc

The PTCU series of Putek TCU temperature control units explores and utilizes various existing main energy sources, such as hot oil, steam, frozen saline water, and cold oil, for temperature control in mixing tanks, chemistry, pharmaceuticals, bioreactors, material testing research, and production. A TCU temperature control unit system can meet the temperature control requirements of different processes in multiple reactors. The purpose is to integrate existing systems and fully utilize existing primary energy sources.

It mainly consists of heating circulation system, cooling system, control system, box, etc. The heating cycle system consists of a circulation pump, an electric heater, an expansion vessel, an exhaust valve, a one-way valve, a thermal resistor, and a circulation pipeline. The cooling system consists of oil-water heat exchangers, oil-oil heat exchangers (some equipment), cooling water solenoid valves, high-temperature solenoid valves, etc. The control system adopts PID control technology, high-definition touch screen display, and is equipped with multiple protection functions to ensure the safe operation of the equipment. By heating and cooling the unit itself, the heat carrying fluid is transported to the outside world to meet the requirements of the process conditions.
