Fujitsu General America released its new Airstage J-IIIL heat pumps in the VRF system line for light- to mid-sized commercial applications. According to the company, the compact and slim design of the J-IIIL VRF line makes it ideal for low rise and urban buildings where limited installation space is a challenge. Front-facing fans and a compact chassis permit the outdoor unit to be installed in narrow spaces, whether ground- or wall-mounted.
Taco Comfort Solutions’ new PF Series plate and frame heat exchangers are ASME designed and constructed. According to the company, computerized product selection greatly simplifies the process of choosing the correct heat exchanger for the required application. The compact size of PF Series heat exchangers, make it an ideal for a wide range of commercial applications.
Johnson Controls has announced the release of its UL Certified TYCO® LFP™ Antifreeze. This third-party tested and evaluated solution helps fire protection systems comply with National Fire Protection Association (NFPA) 13, 13R, and 13D, which require the use of listed solutions in new antifreeze systems. Existing antifreeze systems must meet this requirement by 2022 under NFPA 25.
The SLX high output ultraviolet fixture from UV Resources disinfects HVACR airstreams, cooling coils, and drain pans. The SLX fixture, which stands for Single Lamp eXterior-mounted fixture, offers facility managers and building owners an option to disinfect air and surfaces that are typically inaccessible from inside the air handler.
FLIR Systems has released its FLIR VT8-600 and VT8-1000 voltage, continuity, and current testers. The testers troubleshoot and verify electrical installations or systems within commercial and light industrial facilities. The company says the electrical meters are compact enough to reach into cramped openings or crowded cabinets (51-millimeter width), while providing an open-jaw design for current measurements and large-diameter cables (up to 15.5-millimeter diameter).
Johnson Controls has released Metasys 10.0 for building management. The company says the latest Metasys aims to provide facility personnel with smarter building automation, faster responses to critical alarms, and new integrations with fire detection, security, and lighting systems – all with visibility from a single common interface.
On Demand Stricter refrigerant regulations combined with increasing demands for energy efficiency mean the systems of tomorrow must perform at superior levels, a lower cost, and with minimal flammability. Oil-free systems can help achieve these benefits and more. This webinar will give an overview of what oil-free systems can offer with a focus on water-cooled chillers, air-cooled chillers, and heat pump applications.
On Demand Using PEX in hydronic heating and cooling applications is a growing trend in the commercial building industry due to the product’s durability and ease of use. This webinar will focus on the benefits of PEX in hydronic applications, including fan-coil units, VAVs, AHUs, unit heaters, radiant manifolds, and more and explore the differences and similarities of using PEX compared to other piping materials.
Engineered Systems magazine’s June 2019 issue examines the role of HVAC systems and power in colleges and universities via the decentralization of a Missouri college’s central boiler plant, an examination of ventilation considerations in Group R-2 facilities, the steps engineers should consider when overcoming unanticipated boiler room setbacks, common calculations and considerations regarding NFPA 92, and much more.
