Frequently Asked Questions
What are the advantages of the semi-hermetic screw compressor?
The semi-hermetic screw compressor offers highly efficient operation, smooth running with low noise levels, suction motor cooling to maintain low temperatures, and a long service life with premium bearings designed to last at least 40,000 hours.
Which refrigerants are compatible with the LS-WSCS screw chiller?
These chillers are designed to be highly adaptable and are suitable for R22, R134a, R404A, and other common refrigerants depending on your specific cooling requirements.
How does the energy regulation program save power?
The chiller features an adjustable energy regulation range (either 0-33-66-100% or 0-25-50-75-100% depending on the model), allowing the system to match the actual load demand precisely and maximize power resource savings.
Can the chiller be integrated into a building control system?
Yes, the system can be connected to building control systems or remote controls using an optional control module, and it supports chain control for chilled water pumps, cooling water pumps, and cooling towers.
What safety protection devices are built into this screw chiller?
The unit is equipped with comprehensive security features including compressor motor overheating protection, overload protection, high/low pressure protection, frost protection, power reverse phase/phase protection, exhaust over-temperature protection, and flow switches.
What is the main difference between the Single head and Double headed models?
The Single head models (WSCS) utilize a single compressor configuration for standard load requirements, while the Double headed models (WSCD) feature dual compressors for larger refrigeration capacities, higher airflow, and enhanced redundancy.
