NQV Series 5 To 30 Ton

Accuchiller NQV with Variable Speed Scroll Compressors

5 to 30 ton

Same great features as the NQ Series portable chiller with the addition of an optional variable speed compressor for significant energy savings!

Available from 5 to 30 ton

Overview

A conventional portable chiller uses a compressor running at a continuous speed, also known as a fixed speed compressor. Regardless of the requirements placed on it by the process load, the compressor speed remains at 100%. Fixed speed chillers employ a “hot gas bypass” to maintain the demand on the compressor to avoid wide fluctuations in the coolant temperature delivered to the process for consistent output.

Variable Speed Compressor Payback (Years)

Compared to a typical chiller with a fixed speed compressor, a NQV chiller with a variable speed compressor provides major power savings at partial loads. This is particularly important in process applications which run varying loads that rarely use full capacity of the chiller. Variable speed scroll compressor technology varies the compressor speed to match the process load. This means the compressor slows down under part load conditions for peak performance and reduced power use. 5, 10, and 15 ton units use one variable-speed compressor. A 20 ton unit uses a 10 ton variable-speed and a 10 ton fixed-speed compressor and a 30 ton unit uses a 15 ton variable-speed and 15 ton fixed-speed compressor.
