Central Plant Energy Control Systems

Optimized Variable Speed Solutions or New and Existing Chilled Water Plants

Kiltech provides self-learning and calibrating, real-time, automated central plant optimization called CPECS (Central Plant Energy Control System)., saving you thousands of dollars when your equipment is operating at part loads.

BAS Controls Cause System Over-pumping and Increase Energy Expenses

Typical building automation systems control equipment via fixed set points and schedules. If on one hand they help facilities management on a daily basis, on the other hand these systems have limited knowledge of the actual equipment being controlled and how their performance changes at different operating conditions.

For example, a BAS controls a cooling tower to a fixed 78°F, chillers are sequenced on once they reach full capacity, chilled water setpoint is adjusted based on a fixed time of day schedule, and chilled water pumps operated to maintain a fixed pressure.

Typical strategies such as above often result in over-pumping a system and have been proven to consume as much as 75% or more energy than necessary at part load.

ASHRAE studies conclude that air conditioning applications operate at part load over 96% of the time. Thus, any time a variable speed chiller plant operates at less than maximum capacity there is an opportunity for optimization of set points and flows without compromising occupant comfort or process temperatures.

The solution is in controlling and optimizing the central plant, and with that eliminate over pumping.

Stop Over Pumping and Achieve Efficient Chiller Plant With Cooling Tower Control and Optimized Total System Energy Approach

Kiltech CPECS is a central plant control system that optimizes any chiller and central plant orientation by staging and varying every component speed to prevent extra RPM in any motor at any time.

CPECS eliminates over-pumping in your cooling tower, chiller compressor, and pumping loops. It allows for variable flow optimization even when thermal storage, battery energy storage, hybrid absorption, and electric systems, and various types of chillers are in use.

It can be delivered as an overlay to the existing controls system or as a full automation solution. End users typically see over 20% of improvement in system performance as a result of advanced optimization sequences, which pays back very quickly.
