This chiller plant retrofit team encountered challenging existing conditions and an-swered with savvy choices for piping and valves as well as the chillers. Good communication, accurate documentation, and a creative bidding idea you might want to borrow also contributed to bringing the mechanical work in effectively and on budget.
Pressure independent control valves proved to be a key in wringing the benefits out of smartly managed chilled water temperature, but that wasn’t all. Airside energy recovery, desiccant dehumidification to eliminate reheat in operating room environments, and upgrading to ECM fan systems have all contributed to this hospital’s fiscal wellness.
For use in a wide range of processing applications ranging from sanitary and food processing to water treatment and chemical operations, Matco-Norca now offers a range of carbon steel and stainless steel (CS & SS) valves.
Danfoss says it has developed the new TU with F-charge TXV to help OEMs meet the new U.S. Department of Energy commercial refrigeration energy efficiency standards. The new F-bulb charge delivers low superheat in low- and medium-temperature refrigeration ranges, includes asymmetric ballast material that is proven to deliver more stable temperature control and, like all Danfoss TXV bulb charges, is HCFC-22 free.
Uponor North America is launching a new stainless-steel manifold targeted for residential and commercial radiant heating and cooling applications. Made of corrosion-resistant stainless steel, the manifold is available in 1-in and 1.25-in sizes in two through eight, 10, and 12 loop configurations.
Flomatic Corp. introduced its new Model 80DICL-VFD, a special patent-pending submersible pump check valve for use with VFD control submersible pumps. According to the company, standard check valves will “chatter” and be noisy when a VFD goes to low flow, causing premature wear and eventual failure.
