Future VENTUS LUX product enhancements will include other services and components such as smoke detectors and lighting controls.
Bitzer has modified all models of its 2-stage reciprocating compressors to enable them to run with R448A and R449A refrigerants. With low global warming potential (GWP) values of 1386 and 1397, both refrigerants are eco-friendly alternatives to R404A.The EU F-gas Regulation prohibits the use of R404A beyond the year 2020 in stationary areas.
Greenheck’s line of Model EQB mixed flow inline fans has expanded with the addition of five new sizes. Now available in eleven sizes, 9 through 33, Model EQB offers a performance range up to 26,000 cfm and static pressure up to 3 in wg. All Model EQB sizes are licensed to bear the AMCA Seal for Sound and Air Performance.
Big Ass Fans® unveiled the redesigned LED attachment for the Powerfoil®X2.0 ceiling fan. The LED produces up to 20,700 lumens, equal to the light output of 25 60-watt incandescent bulbs. For spaces that require less light, there are 9,050- and 14,500-lumen configurations available.
Daikin Applied’s new SmartSource™ Compact vertical water source heat pump (WSHP) is designed to help facility managers and engineers who need to maximize building floor space and budgets.
