FAQ - Screw Compressor Chillers

Question 1

What is the difference between a screw compressor and a scroll compressor?

Accepted Answer

The screw compressor is ideal for high-capacity applications (above 50 TR) with 24/7 continuous operation, offering lower vibration and greater durability. The scroll compressor is better suited for smaller capacities (up to 25 TR) with intermittent cycles.

Question 2

What is the maximum capacity of a screw chiller?

Accepted Answer

Helioterm's screw compressor chillers reach capacities from 50 to over 500 TR in a single unit, and can be combined in larger systems for even higher demands.

Question 3

Can a screw chiller operate 24 hours a day?

Accepted Answer

Yes, screw chillers are specifically designed for 24/7 continuous operation. The continuous rotary motion of the screw compressor results in less mechanical wear and longer maintenance intervals.

Question 4

What is the energy consumption of an industrial screw chiller?

Accepted Answer

Consumption varies according to capacity and operating conditions. Screw chillers offer excellent efficiency at partial loads, with typical COP of 3.5 to 5.0, resulting in significant energy savings in large-scale operations.

Question 5

Which industries use screw compressor chillers?

Accepted Answer

They are widely used in large-scale industries, petrochemical plants, steel mills, metallurgical plants, shopping centers, large hospitals and any application requiring high continuous cooling capacity.

Question 6

What is the lifespan of a screw compressor?

Accepted Answer

With proper preventive maintenance, screw compressors can operate for 20 to 30 years. Helioterm offers preventive maintenance contracts and spare parts to ensure equipment longevity.
