The Chiller Wasn’t Failing. It Was Overloaded.
A Saturday night no-cooling call looked like a chiller problem. The machine was running but not making setpoint. The calculated load showed the real issue: the plant was pushing the chiller to 115% of design.   Read more...
One Extra Reading Exposed a BAS Error Costing Chiller Efficiency
A BAS value can look believable and still be wrong. This real-world example shows how one field-verified reading exposed a tower-control issue that was quietly increasing chiller lift, kW, and operating cost. Read more...
The Gap Between a Chiller Log and a Finding
A chiller log can be completely filled out and still not tell the team what matters. The log records the reading. A finding explains what deserves attention. Read more...
Why Chiller Diagnostics Still Depend on Senior Mechanics
Most chiller logs already have the readings, and the formulas have been around for years. The real gap is that the industry never built a repeatable workflow to turn those readings into trusted diagnostic judgment. Read more...
Evaporator Approach: A Measure of Inefficiency — and Why People Blame It Too Fast
Evaporator approach is a measure of inefficiency, but people blame dirty tubes too fast. This guide explains what the number means, what can move it, and how good techs use it without fooling themselves. Read more...
What Is a Good kW per Ton for a Chiller?
kW per ton is one of the fastest ways to judge chiller efficiency, but it is easy to misuse. This guide explains what the number means, what can distort it, and how to compare it the right way. Read more...
How to Estimate Chiller GPM Using Pressure Drop
Estimate chiller GPM from pressure drop using design flow, design pressure drop, and field readings. Learn where this method helps, where it can mislead, and why flow must be verified before judging tons, approach, or kW/ton. Read more...
