Many chiller owners plan to keep their equipment for the long run. Our retrofit chiller control system lets existing chillers run to the latest standards of control performance, reliability and productivity.
Payback
Modern digital controls come with energy-saving options such as zero-error control, chilled-water reset and chiller soft loading. These savings can pay for the controls retrofit.
Smarter controls
With traditional chiller controls, safety protection is all-or-nothing. In the same situation, a smart retrofit controller unloads the chiller to avoid losing operation. Traditional controls are also notorious for refusing to restart a chiller after it shuts down, a real problem in plant rooms that are not manned round the clock. With a smart controls retrofit, built-in timers can restart a chiller within seconds of a trip.
Replaces obsolete components
Chiller control parts do become obsolete. Upgrading to a complete new retrofit control system means new controls are installed, removing obsolescence concerns.
A more reliable chiller
A chiller compressor has few moving parts, but its controls are complex with many moving parts, so after 10 years or more their reliability can become erratic. With a smart controls retrofit almost all of the existing controls are replaced, giving you a more reliable chiller.
Better information
Traditional controls give the operator minimal information. An advanced retrofit controller displays all relevant performance data, such as heat-exchanger fouling calculations, so problems can be anticipated or prevented rather than simply reacted to.
Building automation integration
A smart retrofit chiller controller is a gateway to the wider capabilities of a building automation system. If your facility already has one, the retrofit controls integrate your chiller into it.
