150HP Air Cooled Screw Compressor Chiller Industrial chemical chiller 150Ton Air cooling machine for Sheet Extruder.

Using chillers to cool sheet extruders is one of the key applications in the plastics processing industry. Its stability and accuracy directly affect the quality of the sheet (such as thickness uniformity, surface gloss, crystallinity, etc.)

Common problems and solutions for chiller condensers:
1. Condenser is dirty and clogged: The fins are covered with dust, oil, catkins, etc., resulting in poor heat dissipation, increased condensation pressure/temperature, and decreased refrigeration efficiency.
Treatment: Clean the condenser regularly (clean scale/biological algae for water-cooled type; clean fins for air-cooled type).

2. Insufficient cooling water flow/too high water temperature (water-cooled type): water pump failure, filter blockage, valve not fully opened, low cooling tower efficiency.
Treatment: Check the operation of the water pump, clean the filter, check the valve opening, and ensure that the cooling tower is working properly (fan, water distributor).

3. Condenser fan failure/insufficient air volume (air-cooled type): The fan motor is damaged, the belt is loose, the fan blades are deformed, the ambient temperature is too high or the ventilation is poor.
Treatment: Check the operating status of the fan, replace damaged parts, and improve the ventilation environment.

4. Condensation pressure is too high: In addition to heat dissipation problems, it may also be too much refrigerant or non-condensable gas (air) mixed into the system.
Treatment: Check the heat dissipation and have professionals check the refrigerant quantity and system vacuum degree if necessary.

The benefits of using air-cooled chillers:

1. No cooling towers.
2. Better environmental stability-no water wastage.
3. Low maintenance costs.
4. Easier to operate and control-tower freezing and tower bypass absent.
5. Chemical costs avoided.
6. Water costs avoided, especially in cities.
