Manufacturing Excellence Since 1931
We’re gearing up for AHR Expo next week!
AHR Expo is the world’s largest HVACR event. It provides a unique forum where manufacturers can come together to share ideas and showcase the future of HVACR technology. Dwyer has had the privilege of participating in this show for several decades.
Stop by Booth #943 for several exciting new product demonstrations and to meet the Dwyer team. Continue reading “See You Next Week at AHR Expo!”
The W.E. Anderson Series ACT Actuators are available in either pneumatic or electric models. The wide range of torques and voltages means there is an actuator for almost any application. The standard ISO 5211 mounting configuration makes installation to any valve or damper quick and simple. W.E. Anderson pneumatic ACT models are a compact rack-and-pinion design with a symmetrical structure that ensures fast and steady action, high precision, and high output power. The corrosion-resistant anodized aluminum body is designed to withstand harsh, abusive industrial environments and provide reliable service. We offer double acting and spring return models in a variety of sizes to fit any application. Continue reading “[Product Highlight] Series ACT Pneumatic and Electric Actuators”
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.'”[1]
— 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).
