1. One to many: A single device can output multiple outputs, with multiple loads, and each path is independently controlled for temperature, saving space; 2. Customized explosion-proof: can be upgraded to positive pressure explosion-proof or explosion-proof explosion-proof

Product recommendations

Non standard customization

The DLS series low-temperature chiller is mainly composed of refrigeration system, circulation system, control system, box, etc. The refrigeration system adopts steam compression refrigeration, and the compressor and main refrigeration components are all from internationally renowned brands, with stable and excellent performance at the outlet water temperature. The temperature control accuracy can reach ± 0.1 ℃, and optional components can achieve multi-channel output and load, which is energy-saving and environmentally friendly, and easy to operate. And it can achieve multiple alarm functions such as overheating, overload, and water shortage, making remote control convenient. It can control various communication methods such as I/O, RS232, RS485, etc

Low temperature chiller

-135 ℃~+225 ℃, can meet the needs of different temperatures, and can be customized non-standard; Optional precise temperature control form, with a maximum temperature control accuracy of ± 0.1 ℃; Using an efficient heat exchanger, the cooling speed is fast, and it only takes 5 minutes to reach -80 ℃ at room temperature; Optional cooling capacity recovery device to improve energy efficiency and avoid low-temperature condensation water. Optional intake flow automatic control and detection

Low temperature air conditioner

The direct cooling refrigeration machine adopts refrigerant direct evaporation, and the cooling method is phase change refrigeration. Compared with the temperature difference cooling of liquid cooling, the cooling speed is faster, the energy efficiency is higher, the equipment has no circulation system, and the external dimensions are more compact!
