Product Profile New pressurization unit coming to North American market
At the 2022 AHR Expo in Las Vegas, Mikrofill Systems Ltd, Redditch, United Kingdom, introduced its Mikrofill 3 hydronic system pressurization unit for the North American HVAC market. The direct-type pressurization unit is available for sealed, low-pressure hot water and chilled water commercial and multifamily residential applications. Able to fill any heating or chilled water system from empty without the use of a pump, the product delivers commercial backflow protection with no RPZ valves, while providing electronic pressure management. It connects directly to the commercial building’ s incoming water supply (main or boosted). Precommissioned sensors monitor system inlet and operating pressure which automatically maintain system pre-sets. When a change in cold-fill water pressure is detected, the sensors open the Mikrofill 3 valves to top off the system. It also provides leak and flood protection. It has a fill rate of 3.8 gallons per minute, based on an incoming pressure of 30 psi. The base requirement is a water-supply pressure of 4.5 psi greater than the cold-fill requirement.

Commercial water heating system Rinnai, Atlanta, Georgia, unveiled its new tank replacement solutions for both contractors and end-users with their all-new non-condensing Demand Duo R-Series commercial water heating system. Its design connects to existing sixinch B-vent, allowing contractors to replace standard-efficiency atmospheric tanks. Sold in 80 or 119-gallon tank options, the Demand Duo R-Series eliminates the need for new vent penetrations and the pre-installed drip leg and 36-inch swivel-flex gas line reduces install time with a pre-installed electrical junction box and duplex outlet. The digital controller allows management of building recirculation without purchasing an additional aquastat. Rinnai u www.rinnai.us
Low GWP compatible compressor Emerson, Sidney, Ohio, introduced its new Copeland ZPSK7 two-stage scroll compressorlineupforresidentialandlightcommercialHVACapplications.The new CopelandZPSK7 is regulation-ready andwilloffer low GWP compatibility while beingoptimized for the R410A refrigerant. The compressors are available in 1.5 to five-ton single phase models, with three-phase compressors following in 2022. The new compressor platform will also help original equipment manufacturer (OEM) achieve additional efficiencies, making them meet new 2023 Department of Energy (DOE) regulations. Emerson u www.Climate.Emerson.com Flood prevention and backflow protection Watts, Burlington, Ont, introduced its LF909-FS with SentryPlus alert technology. Theintegrated flood sensortechnology is now standard on all large diameter (2-1/2 inch to 10 inches) Watts 909 backflow preventers. Flood sensors can be activated with add-on cellular or BMS kits. The sensors are designed to detect discharge from the RPZ backflow ’ s relief valve, so action can be taken to prevent flooding. An integrated sensor is pre-installed at the relief valve, directly before the air gap, on all large diameter 909s.

Low sound rating heat pump Bosch Thermotechnology, Mississauga, Ont, announced the availability of its new heat pumps for commercial spaces — the QV Series. Available in multiple sizes and both horizontal and vertical configurations, the commercial grade QV Series features a low sound rating of 53dB. It delivers a compact cabinet, making it ideal to fit into small spaces in commercial buildings. The systems includes a constant airflow ECM DEC blower to provide the same CFM of airflow as the Bosch LV model, but at a lower RPM. The QV Series features Bosch’ s patented compressor encapsulation, which includes high density mass loaded vinyl insulation material wrapped around the blower. Bosch Thermotechnology u
