In our last blog we suggested incorporating IPLV (Integrated Part Load Values) into your cooling tower lifecycle cost analysis. Next, we need to fill in wet bulb temperatures that correspond with the part load conditions we’ve identified and already added to our lifecycle worksheet. …Read More
Every cooling tower design requires a strategy for supplying make-up water to replace water that is lost due to evaporation, drift or blowdown. This is necessary to maintain the condenser water volume and keep dissolved minerals sufficiently diluted. There are two basic make-up water strategies…Read More
We recently introduced the part load efficiency value (PLEV) aspect of the Bell & Gossett online pump selection tool. PLEV for pumps is based on flow rate while the Integrated Part Load Value (IPLV) for chillers is based on load. This final segment on PLEV will look at the difference.
Let’s begin by examining....Read More

Gone are the days of optional air or waterside economizing. Gone also are the days of waterside economizers piped in parallel. In other words, the “either/or” operation of the chillers and economizers that we’re all accustomed to will soon be a thing of the past.
