Frequently Asked Questions

What is a scroll compressor?

It's a positive-displacement technology using two interfitting, rotary-like movement of spiral-shaped scroll members.

What are the main advantages of scroll compressors in HVAC applications?

They offer excellent efficiency, high reliability, continuous compression with almost no pulsation or vibration, and very few moving parts.

Does a single compressor failure affect a chiller using multiple scrolls?

No, if there are multiple circuits, a single compressor failure allows the chiller to remain in service.

What makes scroll compressors efficient?

The involute shape of the spiral elements allows opposing elements to mesh, and precise machining permits sealing vanes with little oil friction.
