Low temperature storage of biological samples

The refrigeration system adopts a single compressor refrigeration and a two-stage cascade refrigeration method. And it is equipped with multiple protection functions to ensure the safe operation of the equipment. Through the refrigeration of the unit itself, the liquid low-temperature refrigerant is sent to the end evaporator for cooling, creating a low-temperature environment that meets the requirements of the process conditions.

Adopting single machine self stacking technology, it occupies a small footprint and can integrate two sets of systems for switching and use
Constant temperature range:
-60℃±1℃
-80℃±1℃
-120℃±1℃

Product recommendations

Non standard customization

It mainly consists 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. Ensure the safe operation of the equipment for external applications that require rapid cooling.

Ultra low temperature freezer

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

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!
