Technical Systems (TSI), a division of RAE Corporation, has announced the availability of its Series 35 Evaporative Cooled Chillers. The company says the chillers have been specifically designed to provide-highly efficient cooling for commercial and industrial-duty applications.
Greenheck’s new Model EVH-501D stationary vertical blade louver is Florida Building Code Approved for use in the High Velocity Hurricane Zone and Miami-Dade Approved for use where the room behind the louver is not designed to drain water penetrating into the room or the room will house non-water resistant or water proof equipment, components, or supplies.
Daikin Applied has developed its redefined Pathfinder. The company says this makes it the first air-cooled chiller with variable volume ratio technology, allowing for greater customization. Rivaling the efficiency of water-cooled chillers, officials claim the newly upgraded Pathfinder is also equipped with new variable speed technology, offering easier maintenance and improved part-load performance.
Titus HVAC has introduced the VENTUS LUX, an integrated chilled beam system that combines the efficiency of chilled beams with LED lighting. The company says the compact system is 30% more energy efficient than conventional overhead VAV systems and installation time is faster and more affordable. 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.
