SWEP’s new 250AS model is specifically developed for high-efficiency air- or water-cooled reversible chiller applications. Large ports and asymmetric plate design enable an effective operating range of 80-250 kW (23-71 tons).
Danfoss has introduced the new Danfoss Turbocor® TT700 compressor — expanding to a larger capacity its existing range of Turbocor® TT series compressors. Designed for water-cooled chiller applications, the new TT700 compressors are oil-free, variable-speed, magnetic bearing centrifugal compressors that provide full- and part-load energy efficiency. The company claims the compressors also feature a small footprint, are light weight, and offer low vibration, very low sound, intelligent controls, and soft starting characteristics.
International Environmental Corporation (IEC) introduced its new Horizontal and Vertical (HDY/VDY) Direct Drive Blower Coil Series. Accommodating a variety of applications, these models are equipped with a direct-drive EC motor, eliminating belt-drive slips and other concerns associated with belt-drive systems. The company says the new line offers an alternative that is more reliable and efficient, resulting in increased energy savings, an extended motor life, easier installation, and less maintenance.
Franklin Electric’s new Little Giant VCC-20-P Series is designed for automatic collection and removal of condensate from air conditioning, refrigeration, and dehumidification equipment installed in air handling and plenum applications.
Viega introduced 12 new reducer and union options for the Viega MegaPress and MegaPressG systems for schedule 5 to schedule 40 carbon steel piping systems in sizes .5-in to 2 -in. The Viega MegaPress system uses modern cold press connections for pipe installation, ideal for hydronic heat, chilled water, compressed air, low-pressure steam, and more.
Twin City Fan & Blower announced availability of the new light duty (Class-L), direct drive, Utility Set- DCV. The new DCV Class - L is available with the GridSmart™ Electronically Commutated (EC) motor up to 3 hp applications.
RectorSeal® LLC has introduced AC Leak Freeze® Pro, a refrigerant leak sealant applicator for residential and commercial refrigeration and air conditioning systems.AC Leak Freeze Pro is an 11.5-in-long applicator that consists of a flexible, transparent refrigeration hose and an attached copper reservoir, which contain a total 1.46-ounces of the same ac leak sealant formula as the d syringe-based AC Leak Freeze injector. AC Leak Freeze Pro doesn't require a system pump down with R-410A systems and safely withstands all typical refrigerant pressures.
Why was one floor’s laboratory ventilation failing to keep up, when it was even the closest floor to the rooftop fans? Some system sleuthing led two engineers to a fitting conclusion. Read more stories in May Issue 2017.
