Air Cooled Glycol Chiller System Glycol Air Cooled Chiller Low Temperature Air Cooled Chiller Plant Brine Chiller
Glycol Chiller Low Temperature process chiller
Glycol chillers are industrial refrigeration systems that use for glycol mixed with water for anti-freezing, to lower the freezing point of the circulation water in the cooling system.
Air-cooled chiller is built-in insulation water tank and water pump, no need to add another cooling tower to heat. It is very easy to install and move. But it has high requirements on the working environment. It is cooled by hot air circulation, so if the ventilation effect of the installation workshop is not good, it will directly affect the refrigeration effect of the chiller.
Application
Industrial glycol water chiller unit is used to cool the hot parts of the equipment, so that the equipment can work normally at low temperature. Used in Beverage filling, spindle cooling, CNC machine tools, grinding miller, reaction system, welding machine, cutting machine and other equipment, temperature adjustment range can be 40 degrees below zero.

Features of glycol cooling system
- The glycol small water chiller use semi-closed piston compressor, high refrigeration efficiency, excellent performance.
- Glycol solution can be used as a secondary refrigerant.The industrial glycol chiller outlet temperature of chilled water can reach -40 ℃.
- The air cooled glycol chiller design is very compact and made by high-quality copper tube fin condensers, high efficiency plate heat exchanger, stable performance, low noise and long service life.
- The glycol chiller with low temperature water has high pressure, low pressure, overload, water level, phase sequence and other protections to ensure the safe operation of the chiller unit.
- The chiller water tank contains a floating ball automatic water replenishment device which is used to measure and control the water level, so as to effectively save time for customers and improve work efficiency.

How to ensure your product with good quality?
- We are specialized in producing industrial chiller since 2004, located in Shenzhen China and give top priority to our quality. All products pass strict multi inspection process which gives customers multi guarantee, most of the accessories use world-class brands, such as Danfoss, Copeland, Schneider electrical components and so on.
- After industrial chiller assembly, we will charge nitrogen for pressure maintaining testing for 24hrs, to check whether there is leakage in the chiller cooling system.
- We will provide testing videos, pictures during chiller testing.
- After the chiller testing commissioning, cleaning and labelling the chiller unit, then go for pre-delivery inspection before packing with plywood cases to to ensure that the chiller can be in good condition during transit.
How to select the model of the chiller ?
- We need to know the heat load of your process or chiller cooling capacity.
- Required water temperature, water pressure and flow rate.
- Application and power supply in local.
- Max. Ambient temperature in summer day
