KALXCWG Chiller Selector and FEMP Compliance Check
Enter your design cooling load. Returns the matching magnetic bearing chiller model, its kW/ton equivalents, and whether it clears the U.S. DOE/FEMP efficiency requirement for its capacity band.

Multiple-unit plant required
A load of TR exceeds the 1,250 TR top of the KALXCWG range. The nearest single-machine building block is the KALXCWG 1250EVT; a plant of units would cover this load before redundancy is added.

DOE / FEMP compliance — part-load-optimized water-cooled centrifugal
| Metric | FEMP requirement | KALXCWG | Result |
|---|---|---|---|
| Full-load efficiency | ≤ kW/ton | kW/ton | |
| Integrated part-load value | ≤ kW/ton | kW/ton |
Ratings from the KALXCWG specification sheet, measured at AHRI 550/590 test conditions. kW/ton = 3.517 ÷ COP (full load) or 3.517 ÷ IPLV (part load); lower is better. FEMP thresholds are the U.S. Department of Energy Federal Energy Management Program minimum efficiencies for part-load-optimized water-cooled centrifugal chillers. This tool is a first-pass selection aid, not a substitute for a plant load calculation at your condenser water temperature.
