Danfoss has launched new models for its Turbocor® TG series for low global warming potential refrigerants. The compressors enable chiller manufacturers to build climate friendly and sustainable solutions that support refrigerant regulations for reducing the direct and indirect CO2 emissions such as the European F-Gas Regulation and the US Environmental Protection Agency’s SNAP regulations.
Schaffner EMC introduces the ECOsine® Active 3420, a harmonic filter which provides harmonic compensation in real-time for industrial and commercial environments. With a capacity of 30 to 300A, operating at 200-480VAC (+/- 10%), the connection-ready 3420 (3-wire) cabinet models include forced air cooling and internal liquid cooling (200-300A), for the power electronics.
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.
EVAPCO, Inc. launched the eco-LSWE and eco-LRWB series of closed circuit coolers. The coolers feature EVAPCO’s Ellipti-fin™ spirally-finned coil and CROSSCOOL™ internal tube enhancement for energy and water efficiency.
Johnson Controls has expanded its YORK line of YLAA Air-Cooled Scroll Chillers up to 200 tons. The company says the extended capacity of the YLAA offers a more cost competitive solution to 200-ton opportunities without sacrificing size, quality, and efficiency.
Lochinvar is introducing an addition to its Power-Fin line with the Power-Fin High Efficiency Commercial Boiler. This product expansion of the original line, which launched in 1986 and just celebrated its 30th anniversary, now offers an input capacity from 2.5 to 5 million Btuh, more than doubling its previous capacity. The enhanced performance comes from a heat exchanger that features a double row of swept fins that delivers more than twice the output of the original model.
SPX Cooling Technologies, Inc. has introduced the Recold Vector™ Adiabatic Cooling System, for halocarbon refrigerant condensing or CO2 gas cooling applications in supermarket refrigeration systems. According to the company, the Recold Vector provides lower energy usage and a smaller footprint than an air-cooled condenser and up to 60% or more reduction in site water usage compared to an evaporative condenser. Designed as a once-through system, the Recold Vector Adiabatic Cooling System minimizes water treatment requirements.
Para Systems Inc. has released the Minuteman Entrust LCD Series of UPSs. The company says this new line of uninterruptible power supplies (UPSs) offers complete power protection designed to protect valuable equipment.
The model 14359 UL/C-UL Listed Class 2 Transformer from Foster Transformer accepts line voltages of 120, 208, 240, and 480 V, 50/60 Hz, allowing near universal application. Its 24V, 75 VA rating provides ample capacity for most low voltage control applications, and its integral wiring compartment simplifies field installations, according to the company.
Trane has expanded its ductless portfolio to include the new Trane® Water-Source VRF Ductless Systems. The company reports that the new systems provide energy-efficient climate solutions for multi-tenant and diversely occupied buildings, including commercial real estate, and K-12 and higher education facilities.
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.
