We met with an original equipment manufacturer (OEM) last year, who was working on a new design for rooftop air handling equipment. Part of the their design utilized water flow for cooling in a loop.
Low or no-flow conditions can cause major damage to expensive pumps, motors, and other equipment, which could result in extensive downtime and repair costs. In order to prevent this, the customer needed an inexpensive, but reliable and robust method for proving water flow. Continue reading “Proving Water Flow in Rooftop Air Handlers”
“In the real estate industry you always hear this phrase, ‘Location, location, location.’ I think for energy management systems the key is ‘Execution, execution, execution.'”
— Sara Lisauskas, Energy Management Systems: Maximizing Energy Savings
What comes to mind when you think of the phrase “energy efficient?” Perhaps you think of LED light bulbs, electric cars, Energy Star appliances, or LEED-certified buildings. But energy efficiency isn’t limited to “green” products or certifications. Continue reading “The Key to Energy Efficiency”
Electrostatic discharge (ESD) is a unique phenomenon that can be seen in everyday life. The effects of ESD can be seen by rubbing a balloon on your head, resulting in your hair sticking to the balloon, or by touching a doorknob or a pet in a dry building and receiving a static shock.
In irrigation, well water pumping, and pressure boosting applications, ESD can cause larger issues than just a small shock to your finger. Because plastics used in PVC pipes are insulators, the moving water builds up static electric charges. Eventually, this static electric buildup will discharge through an ungrounded pathway (e.g. instrumentation or sensors used to control a pump). Continue reading “ESD and Surge Issues in Pumping, Pressure Boosting, and Irrigation Applications”
As the year comes to a close and we celebrate this time with our families and friends, all of us at Dwyer want to give a big thank you to the customers and teammates that we’ve depended on the year through. We certainly couldn’t have done it without you. Continue reading “Happy Holidays | Year in Retrospect”
A daisy chain is a wiring strategy where multiple devices are wired together in sequence. This is similar to the way in which flowers can be linked together to form chains or rings, using flower stems as a chain to connect each flower to one another.
In this example, a pressure transmitting cell is the “daisy” and a circuit loop is the “chain.” Continue reading “The Basics of Daisy Chaining”
