Portable 25 ton low temperature chiller 25 HP glycol chiller
Product Description
Portable25 Ton Air Cooled Chiller Glycol Water Chiller Low
Temperature Water Chiller Laboratory Low Temperature Circulation
Low Temperature Glycol Chiller
Low temperature glycol chiller is a kind of water cooling
equipment, it can provide a constant temperature, constant current,
constant pressure of a cooling equipment. The glycol chiller water
is between -5℃ and -40℃ and the chilled water will be transported
to the equipment or products that need cooling through chiller
pump.
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 COP efficiency of air cooled glycol water chiller is about
2.6-3.3. According to the industrial needs, it can be refrigerated
or heated, which is more used in general laboratories and small
production lines.
- The COP efficiency of water-cooled chiller is relatively high,
about 4-5.5, which is used in industrial process cooling and
large-scale construction projects.
- Compared with the high efficiency wate cooled chiller, the
air-cooled chiller is only different from the condenser. The
low-temperature air-cooled chiller dissipates heat directly through
the fan, while the water-cooled chiller takes away the heat from
the condenser through cold water and dissipates heat through the
cooling tower.
- The water cooled low temperature water chiller can only
refrigeration, if the need for heating, need other heating
equipment.
