DLSB series low temperature Cooling Liquid Circulating Pump adds the circulating water pump on the basis of the refrigeration. The new design is elegant and the circulation system is made of stainless steel, with anti-corrosion, anti-rust, anti-cold liquid pollution and other properties.
What are the Types of Chillers?
There are several types of chillers, including the water-cooled chiller, air-cooled chiller, and evaporation cooled chiller. These different kinds of chillers have different characteristics, advantages and disadvantages. Water-cooled systems can offer a high efficiency and environmental impact advantages over air-cooled systems.
How does a Chiller Work?
A chiller consists of the usual evaporator, condenser, compressor, and expansion device set up. The working process of a chiller can be simply described below. A chiller can cool water or oher fluids, which are used to cool equipment. After absorbing heat from what is being cooled, the water or other fluids can go through the chiller. In the chiller, the heat is transferrred from the fluid to the ambient air.
Some Tips on Using a Chiller
1. All operators should read this specification before proceeding;
2. If it is not specified as “explosion-proof” type, this equipment is not suitable in flammable and explosive workplaces.
3. This equipment is not used in places where the environment is rotted seriously;
4. Strong magnetic fields may affect the normal operation of the machine, so the device is not suitable for environments with strong magnetic fields;
5.This equipment allows the working environment temperature range of 5 ° C ~ 30 ° C, humidity ≤ 85%, beyond this range will affect the safety and usage performance of the equipment.
Next, I will introduce the latest Low Temperature Cooling Liquid Circulating Pump:
