Maintaining the indoor air quality of your building has never been a more important. From allergens to mold to CO2, indoor air that contains unhealthy levels of airborne contaminants, gases or pathogens is a threat to human health, safety and productivity. But with the arrival of COVID-19, school, office and retail building occupants got an…

Trapped air in chilled and heating hot water systems is the biggest source of problems we see in the HVAC industry: it forces pumps to work harder, less efficiently and more noisily. Air also contributes to corrosion, which introduces rust particles and debris into the HVAC water flow. Dirt and air are both insulators so,…

Learn Why Vertical Inline Is a Better Option than Base-Mounted, Centrifugal Pumps In years past, centrifugal pumps operated horizontally and were bolted to the floor. These base-mounted, pumps were a maintenance nightmare – requiring the removal of the motor to replace seals and perform other repairs. At 10 pounds per horsepower, motors in base-mounted pumps…

With hydronics experience dating back to 1971, we frequently encounter people using condensing boilers in non-condensing applications. Why? In Chicago and other locations with cold winters, non-condensing boilers work well when it’s cold out and system temperatures are maintained at 160 to 180° F but are much less efficient when it’s warmer, from spring through…

For both duty/standby and multi-pump applications, sensorless technology in Armstrong vertical inline (VIL) pumps offers superior control and maximum energy efficiency. Sensorless Overview Sensorless control enables a pump to decrease or increase its speed to match system requirements without any external signal. In other words, sensorless pumps emulate the performance of a remotely mounted sensor…
