Danfoss says it has engineered a solution that safely controls hot gas injection with the ICSH Dual Position Solenoid Valve. Complying with the latest IIAR safety recommendations for soft gas applications, the ICSH Dual Position Solenoid Valve provides a gradual, time-controlled opening for a smooth pressure build-up in the evaporator before it opens the flow to 100% for full defrost.
Baltimore Aircoil Company (BAC) says it has introduced the first transcritical CO2 TrilliumSeries Condenser that can be applied throughout the United States.
STULZ has added chillers with a stepless capacity control (EC compressor) and an output from 20 to 100 kW to its portfolio. Chillers from the CyberCool Indoor series have been designed for indoor installation. The new version was specially engineered to precisely adapt to low or fluctuating heat loads. With a maximized temperature range from 4ºC to 18°C at the chilled water outlet, the CyberCool Indoor is suitable for a broad range of applications including data centers, medical technology, and process industries.
Armstrong Fluid Technology will introduce a new line of Stainless Steel Vertical In-Line pumps for plumbing applications in residential and commercial buildings at AHR Expo 2018 in Chicago.

As the use of CO2 gas increases in popularity as a natural refrigerant due to its low environmental impact and increasing HFC (Hydrofluorocarbon) regulations, Bacharach is offering a CO2 leak detection monitor for industrial and retail refrigeration applications. This instrument is selective, taking into consideration both response times and operating temperatures in these applications.
LG Electronics USA Air Conditioning Technologies has expanded its line of vertical air handling units (VAHUs). The new VAHU units feature a number of upgrades, most notably four-way installation capabilities. With four-way installation, the new LG VAHUs can be installed vertically, horizontally from the left and right, or inverted with a down flow conversion kit.
Danfoss has released its new RX1200 controller for electric de-icing applications. Designed to complement Danfoss RX de-icing cables for roof and gutter applications, the RX1200 controller helps to extend the life of an outdoor electric heating system and prevent damage and leaks. By sensing both moisture and temperature conditions, the company says the RX1200 can activate or de-activate the cables as needed, reducing energy consumption by up to 75% compared to a controller that measures temperature alone.
