Description
This multi-compressor condensing unit is composed of piston compressor, condenser (water cooled, air cooled or evaporation cooled), frame, oil line system, electric control system, protective devices, high pressure (low pressure) gauge, liquid reservoir and gas liquid separator. The piston compressor condensing units can be divided into air cooled units and water cooled units which are suitable for different occasions. The multi-compressor condensing unit is applicable to agriculture, forestry, fishery, medicine, chemical and refrigeration industries.

Features
1. Piston compressor condensing unit has superior properties. It saves more electricity compared with similar products.
2. The power unit of multi-compressor condensing unit is supplied by the world-famous brand BITZER. It can suit all kinds of working conditions. Its quality is trustable.
3. The condenser has large volume and higher energy efficiency ratio.
4. We remain a good relationship with the supplier, therefore the good quality of the raw materials is ensured.
5. Air cooled condenser has passed air-tightness testing under 3.0MPa air pressure. It is has good air-tightness performance.
6. Multi-compressor condensing unit saves more than 20% of energy than using stand-alone units.
7. Piston compressor condensing unit is running safely. All parameters are constantly monitored. It also has fault early warning functions.
8. This product has a compact structure. It saves space and construction time.
9. The multi-compressor condensing unit has a broad application scope. Its total power ranges from 6 HP to 420 HP and refrigeration temperature ranges from 12.5℃ to 50℃.
10. Oil level controllers are set independently for each piston compressor in order to avoid oil deterioration pollution between compressors.
11. This machine is reliable and long-distance control is available.

1. In order to ensure the refrigeration effect and keep the multi-compressor condensing unit in the best state, the condenser, evaporator and filter should be washed regularly.
2. Cooling water tower and the cooling fin should be cleaned regularly to maintain good heat dissipation effect.
3. The chilled water pump shouldn’t run when water tank is empty.
4. In order to prevent the evaporator from freezing, the temperature switches should not be set to below 5℃.
5. Clients should lubricate the multi-compressor condensing unit regularly. As long as it is running well, the unit can be lubricated every 20000 hours or four times a year.
6. When the temperature of the chilled water reaches the set value, the compressor would stop automatically.
7. Once the refrigerant part is in water, the water chiller should be stopped immediately. Clients should remove the water from the water tank and inform maintenance man in order to prevent the compressor absorbing water into the unit and cause great damage to the multi-compressor condensing unit.

Package and Delivery
This box type condensing unit is delivered through freight transportation in wooden packages. This product can be delivered in time.
