The inputs and outputs (I/O) of VFDs are seemingly modest terminals and may initially appear intimidating. However, mastering their application unlocks a whole new world of possibilities for your pumping system.

By focusing on water quality, you can ensure the safety of water system users, increased life span of the equipment, and compliance.

Founded in 1821 with a focus on liberal arts, Amherst College has seen an 85% increase in enrolments in STEM classes during the past 15 years. Consequently, a new Science Center opened in the fall of 2018 that embraces sustainability. 
 

Today’s heat pump technologies provide a variety of ways to help building owners comply with regulations around decarbonization and meet their ESG goals. 

To enhance installation flexibility, the XCalibur line offers two- and three-inch dual pipe direct venting, ½- and ¾-inch gas line options and universal indoor/outdoor installation.

The built environment is not made up of the latest and greatest equipment that we see at tradeshows and greenfield construction sites. We're still using the old technologies, so can't we find some way to make them better?

The Hydraulic Institute (HI) recently announced the recipients of its prestigious awards which were delivered at the HI 2024 Annual Conference Awards dinner.

The Hydraulic Institute (HI) installed new leadership during the 2024 Annual Conference in Ponte Vedra Beach, FL.

This article explores how to refine and enhance the efficiency of pumping to match precisely to load, balancing the interests of pump experts — favoring primary-secondary piping — with those on the “boiler side” who prefer a variable speed/variable flow approach.  

Evaporative cooling towers play an important role in green buildings by significantly reducing energy consumption when they supplement or replace traditional air conditioning systems, thereby reducing carbon footprint and operating costs.
