Mitsubishi Electric Trane HVAC US (METUS) has expanded the S-Series (PUMY) air-source heat pump outdoor unit to include Hyper-Heating INVERTER® (H2i®) technology in select models. Part of the CITY MULTI® family of products, the PUMY is a single-phase heat pump suited for light commercial or large residential applications.
Fujitsu General America has introduced new medium static pressure duct indoor units for their single-zone Halcyon mini-split line. This new RGLX line features sufficient static pressure to heat or cool a whole house. Units are available in seven sizes ranging from 12,000 to 48,000 Btuh, with efficiency ratings up to 21.3 SEER.
Cambridge Engineering has further expanded into commercial cooling with the availability of the E-Series and ESC-Series evaporative cooling. The company also made enhancements to its M-Series make-up air units.
Modine Manufacturing Company announced the latest addition to its gas-fired power vented unit heater, the Model BTP. The company says the Modine Model BTP offers the same functionality as its PTP unit upgraded with factory installed blower assemblies. The addition of the blower assemblies allows customers to add duct work onto the unit to better distribute heat and air.
The Rittal Blue e+ cooling units are now available in a roof-mounted version. The units, suitable for enclosures from a size of 800 mm by 600 mm (W x D) upwards, have a cooling output of 1.3 kW. The company says this means that cold air can also flow from above around the devices installed inside the enclosure, such as frequency converters. Alternatively, cooling can also be provided in combination with the new VX25 large enclosure system as a complete integration solution.
Cooper&Hunter added a new series to its current heat pump line-up with single-zone applications. The new Dakota series aims to ensure consistent warm comfort during extreme climate and the condenser heat output capacity allows the unit to work efficiently as a primary heat source even if the temperature drops to a sub-zero level of minus 22ºF.
Danfoss has added new 8.5-ton and 11-ton variable-speed compressors with intermediate discharge valves to its VZH range. The new inverter scrolls are ideal for data center close controls and rooftop units for energy-efficient cooling.
Trane announced the availability of its XR16 low profile side discharge air conditioning unit for split ducted systems. This high-performance, low-profile unit features a side discharge, making it ideal for difficult-to-install applications or in tight space requirements where vertical discharge units prove less than optimal.
