LSB Semi-hermetic Cold Water Unit

Product Introduction:
·LSB water chilling unit is a refrigerating plant providing chilled water. It is able to provide chilled water or chemical solution of -30~20°C according to the demands of customers and is especially suitable for the production processes, needing cooling water, of medicines, chemicals, plastics, food additives, electroplating, electrophoresis, etc..

· The company designs and manufactures water chilling units of different kinds and specifications according to the actual demand of users, with the lowest temperature of -120°C.

Unit Characteristics:

Efficient and Energy-saving

Through the computer control of PLC and singlechip, automatic adjustment is available, cold energy output of more stages can be provided, and dynamic and automatic matching with cold load is realized, so that the unit always runs stably with high efficiency and the technical aim is fulfilled.

Stable and Reliable

Main parts adopt famous-brand products at home and abroad, and the system working is stable and reliable.

The automatic control system of the unit adopts the control of PLC programmable controller or singlechip and is able to realize automatic safety protection of default phase, overvoltage, under-voltage, overcurrent, oil pressure, high voltage, low voltage and electronic type motor overload.

PCL control realizes the automatic balance running time of the compressor to prolong the service life of the compressor. Remote alarming and monitoring interface can be reserved according to user requirement.

Impact Mechanism

The unit adopts impact design philosophy so that the installation floor space is small.

Provide “Modularized” installation, reduce the installation period, reduce pipeline consumable items and shorten on-site construction period.

Cost Reduction

Realize the automatic control of the refrigeration system and lower the daily operation and management costs.

Reduce the investment costs of equipment and machine room.

Improve the safety performance of automation and reduce the investment costs of affiliated safety equipment.

The equipment system is simple and is easy to operate. It has lower operation and maintenance costs than the traditional ammonia system.

Explanation:

1. Normal condition: condensing temperature of 40°C, evaporating temperature of 2°C, subcooling degree of

5°C, and superheat degree of 5°C;

2. Power system: 3P/380V/50Hz. Allowable voltage fluctuation of ±10% and allowable voltage difference between phases of ±2%;

3. The above data take R22 as the performance parameters of refrigerant. Please contact us if other working mediums such as R134a and R407C are needed;

4. The contour dimension is only for reference because it may change due to technical improvement. Please ask for the installation size map at any time.
