According to Johnson Controls, its York LX Series packaged units set a higher standard to heat and cool residential and light commercial buildings, featuring a contractor-friendly design, reliable technology, and an advanced manufacturing process. The units are 29% more efficient, earning a 14 Seasonal Energy Efficiency Ratio (SEER) rating and exceeding U.S. Department of Energy efficiency standards.
Bosch Thermotechnology will introduce a new sealed combustion, high-efficiency stainless steel boiler line with condensing technology. The SSB family will consist of a total of eight models in four separate housing sizes with inputs ranging from 85 MBH up to 1,024 MBH, applicable for use in small studio units all the way up to commercial buildings.
Johnson Controls recently unveiled its new York VRF solution, a benefit of the company’s recent Hitachi joint venture. The ductless and modular HVAC solution heats and cools multiple building zones to increase energy savings, improve occupant comfort, and lower construction costs. VRF features Hitachi’s high-efficiency compressors and is complemented by energy modeling and selection tools to measure and compare VRF to other HVAC technologies.
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.
AMETEK Rotron has released a 19-in rack mountable liquid cooling heat exchanger assembly. The unit is one of a variety of similar heat exchangers that are designed to dissipate over 10kw of heat in demanding operating environments. The heat exchanger assembly is enclosed within a ruggedized 6U (10.5-in) aluminum chassis. The company says the unit is designed for years of reliable service in harsh and demanding applications, including military and commercial equipment racks.
Chromalox says it has introduced a new extreme duty model of its blower heater line. Called the CXH-XD blower heater, the new unit is designed to withstand corrosive and wet environments and is ATEX certified.
Daikin Applied has added natural gas heating as an option to its Skyline™ commercial outdoor air handler line. The gas heat option provides lower operating cost and increased energy saving solutions for building owners and facility managers, while maximizing HVAC system performance, according to the company.
Marlow Industries Europe GmbH has launched the Climatherm range of Air to Air heat exchangers. The new Climatherm range from Marlow brings increased heat power transfer while remaining within the industry standard footprint, according to company officials. Using thermo electrics at its core, these compact designs provide increased efficiency compared with existing designs. Using the latest heat sink technology and ducted air flow, Climatherm was thermally modeled from its concept to optimize all aspects of the design.
