The Luxaire Eclipse rooftop replacement solution from Johnson Controls now offers 10-ton XX packaged heat pumps and 3- to 5-ton ZQ 14 SEER air conditioning units. Similar to other products in the Eclipse series, the units feature an exact-fit replacement design that matches the units to footprints of other manufacturers’ units. The company says this reduces installation time, cost, and complexity by eliminating the need for a curb adapter.
Lochinvar is introducing an addition to its Power-Fin line with the Power-Fin High Efficiency Commercial Boiler. This product expansion of the original line, which launched in 1986 and just celebrated its 30th anniversary, now offers an input capacity from 2.5 to 5 million Btuh, more than doubling its previous capacity. The enhanced performance comes from a heat exchanger that features a double row of swept fins that delivers more than twice the output of the original model.
Hydra-Zorb now manufactures Cushion Clamps specifically for metric pipe sizes. The Hydra-Zorb pipe clamps can be used with polypropylene piping and guards against shock, vibration, and corrosion. They are also made in-house in the U.S.
Pottorff introduced its new 5.5-in aluminum grille for buildings needing protection against violent weather such as hurricanes and tornadoes. The XAV-545 is FEMA 320 or FEMA 361 rated for storm shelters and safe rooms. It is AMCA certified and can withstand design loads of 300 psf produced by extreme wind phenomena. The XAV-545 has a free area of 49%.
Williamson has launched its new FreeStyle® 155k Btuh input Wall Mount Gas-Fired Condensing Boiler. The FS-155 has an AFUE of 94.4% and is available in combi and heat only models.
