Direct cooling refrigeration machine

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!

1. Customizable temperature range from -150 ℃ to 35 ℃
2. Overall foam insulation, good insulation effect, and no condensation on the surface
3. Control evaporation pressure and high stability.
4. Allow customization of non-standard control systems
