Larson Electronics has released the 15 KVA power distribution panel system that converts three-phase 480 volts AC to single-phase 120 volts AC. The MGS-15KVA-120X8O-2X208Y power distribution system is designed to provide a safe and effective way for operators in industrial settings to tap into and utilize power sources independently of the work area. This unit is designed to operate with 480 VAC which then steps down to 120 VAC single phase and 208Y three phase.
Sterling HVAC announced the commercialization of the Xcelon system, a rooftop make-up air unit that combines hydronic condensing boiler technology with advanced air distribution and heat recovery methods for levels of efficiency up to 98%. Conceptualized and developed by Sterling, the Xcelon’s engineering integrates hydronic technology, a new air distribution system, and an integrated control platform to produce ultra-high efficiencies.
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.
SpacePak has introduced AirCell, a new hydronic air distribution system for commercial and residential applications. AirCell is a modular and compact high-efficiency air distribution module that works in conjunction with any hydronic supply system including boilers, reverse cycle chillers, heat pumps, and geothermal systems.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
