Application :               
Product working conditions: 20 to 30 degrees below zero
Applications: Electroplating, oxidation, leather, medicine, printing, machinery manufacturing
Product characteristics:
1. Compared with piston type, it has simple structure, fewer moving parts, no reciprocating inertia force, high speed, smooth movement and small moving.
2. The unit is light in weight and the cooling capacity of single unit is large.
3. Because there is no clearance in the cylinder and the suction and exhaust valve discs, it has high volume efficiency.
4. The screw chiller has fewer vulnerable parts and only one tenth of the piston parts. It has reliable movement and is easy to maintain.
5. Screw chiller and hot water unit is insensitive to wet stroke, allowing a small amount of liquid, without the risk of liquid shock;
6. Easy to adjust, the refrigeration capacity can be steplessly adjusted by sliding valve.
