Greenheck’s new Fire Ready Hood, Model GRRS, functions as a standard ventilation range hood with the added capacity to suppress stove-top fires, addressing the challenge of protecting residential-style appliances used in commercial settings.
To meet the need for optimum efficiency and energy savings across all building loads, Armstrong Fluid Technology has announced that its Design Envelope pumps are now also available for use with single phase power up to 7.5 hp.
The new Greenheck Model EAD-635, an adjustable blade louver in a 6-in deep frame, incorporates a drainable head member and adjustable drainable blades to channel water to the jambs that guide the water through vertical downspouts for escape at the sill.
Paxton Corp. has introduced the V43 stainless steel control valve in sizes .5 in to 2 in NPT. The V43 has been tested by an independent laboratory and found to comply with the new federal, low lead law, ANSI/NSF 372-2011, maximum 0.25% lead.
Bitzer is now offering a range of compressor units for use with the natural refrigerant ammonia (R717). The Bitzer ammonia compressor packs (ACP) are available with a capacity range of 100 to 450 TR. The modular compressor units comprise up to three compressors. For higher capacities, as many as three compressor packs can be connected (up to 9 compressors) and connected to a single controller, increasing the overall capacity up to 1,200 TR. The company says this is ideal for industrial systems.
Telkonet Inc has released The EcoWave™ occupancy-based wireless unitary HVAC controller. The company says the controller is ideal for achieving the balance of energy efficiency and occupant comfort in fan coils, heat pumps, PTACs, and other unitary equipment used in spaces with unpredictable occupancy, such as hotel rooms, dormitories, residence halls, assisted living, public housing, and condominiums. It can be installed as a standalone controller or be networked with the ZigBee® based EcoSmart Intelligent Energy Management System for cloud-based total facility management.
For use with its commercial FHP heat pumps, Bosch Thermotechnology offers a DDC Controller option that is preprogrammed and factory installed to be jobsite ready. The optional FHP DDC Controller is installed with the unit’s Unit Protection Module (UPM) which controls the heat pump’s operations and monitors the safety controls that protect it.
