Danfoss Partners with New AB-QM(TM) Sales Representative for Oregon/Washington

Danfoss has announced its partnership with Johnson Barrow, which will serve as its newest sales representative organization for Danfoss’ line of AB-QM™ pressure independent control valves (PICVs) in Oregon and Washington.

With offices in Portland, Ore., and Seattle, Wash., Johnson Barrow has been serving the Pacific Northwest for more than 50 years. The company represents more than 40 HVAC manufacturers and is committed to providing quality service and cutting-edge system technology.

“AB-QM™ PICVs are precise control valves that enable improved efficiency and indoor comfort, and lower installation and balancing costs - important benefits for today’s energy- and cost-conscious market,” said Jim Hoctor, national sales manager for Danfoss. “We’re pleased to now have Johnson Barrow’s expertise and service behind the valves in the Oregon and Washington HVAC markets.”

Ben Iwen, sales engineer at Johnson Barrow, commented: “We are very excited to form this partnership with Danfoss. The AB-QM™ is an ideal complement to our current lines of VAV boxes and fan coil units. Danfoss is changing the market for PICVs and we’re happy to be joining the team to provide this energy savings opportunity to the Northwest U.S.”

About Danfoss AB-QM™ valves

Danfoss’ comprehensive line of AB-QM™ pressure independent valves directly control the water flow required by the coil, and are not affected by pressure fluctuations in the system. By precisely controlling the flow, PICVs eliminate the need for balancing valves, thus reducing the installation and balancing costs.

As an all-in-one balancing valve and differential pressure controller, the Danfoss AB-QM™ pressure independent control valve (PICV) provides 100 percent valve authority, accurate flow limitation, and precise control of hydronic systems, contributing to substantial energy savings, improved overall system efficiency, and enhanced indoor comfort.

In fact, the AB-QM™ has been third-party verified to offer balancing and control accuracies of ±5% of setpoint - leading to increased energy savings of 20 to 50 percent. And, compared to traditional balancing valves, the Danfoss AB-QM™ PICV eliminates the need for authority calculations and will save time on installation and commissioning.

Available in a full range of sizes from ½“ to 10” with a compact design able to handle any size application, the AB-QM™ is ideal for small spaces such as fan coil units and VAV boxes, as well as large buildings like offices, universities , hospitals, and buildings where accurate temperature control is critical, such as laboratories and research facilities.
