The refrigeration and heating equipment is commonly referred to as the TCU system in the chemical industry. This mainly utilizes existing energy sources (steam, circulating water, and chilled water), integrating primary energy into a single flow system or secondary circuit for accurate temperature control of process equipment. The medium of the integrated cold and hot temperature control machine continuously conducts heat to the jacket of the reaction kettle, instead of directly controlling the temperature of the reaction kettle through steam, cooling water, and ultra-low temperature medium. The refrigeration and heating equipment automatically adjusts the temperature required for the overall reaction through big data calculation.

The PTLD series low-temperature freezer mainly consists of a refrigeration system, a circulation system, a control system, a box, and so on. The refrigeration system adopts steam compression refrigeration, and the compressor and main refrigeration components are all from internationally renowned brands.

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

In the product development and production processes of the chemical and pharmaceutical industries, temperature control is crucial for safe and high-quality reaction products. Putec's PTHC series is suitable for process industry and process engineering, and is applied to dynamic constant temperature control of cold and heat sources such as jacket reactors, microchannel reactors, reaction devices, combined chemistry, as well as low-temperature distillation, distillation, extraction and other equipment in the pharmaceutical industry.
