Advanced Cooling Technologies, Inc. (ACT) has launched its HSC, HPC, and LNC series of sealed enclosure cooler products. Sealed enclosure coolers are used to dissipate heat inside enclosures or cabinets that house and protect electrical/electronic equipment from harmful environments.
Designed with the needs of building owners and their specifying engineers in mind, Cambridge Engineering has introduced a new line of Blow-Thru® Direct Gas-Fired Space Heaters to heat smaller commercial and industrial facilities.
The Liberty Series by Ace Heating Solutions LLC is a fully condensing, commercial water heater/boiler. According to the company, the Liberty is designed with high quality materials, including a stainless steel heat exchanger, allowing for a long service life.
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.
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.
