The new TED40x2 low-leakage, insulated control damper from Ruskin® features insulated airfoil blades, which the company says offers greater strength, produces less sound, provides greater sealing ability, and reduces static pressure loss.
Multi-Wing says its EMAX4™ Fans provides up to 77% total efficiency. The customized fan has a computer-optimized blade design for maximum performance. According to company officials, the EMAX4 decreases noise by 2 to 3 dB and reduces energy consumption in air-cooled condensers, commercial refrigeration, chillers, cooling towers, evaporators, and more.
A new critical environment damper series from Ruskin® is designed and manufactured to withstand the elements of coastal and corrosive applications. The CD50CE and TED50CE combine the strength of stainless steel and protection of anodized aluminum to combat salt water elements.
Greenheck’s new line of ceiling radiation dampers are UL classified for installation in wood truss floor/ceiling assemblies. Model CRD-1WT is designed with a plenum box for side inlet or outlet duct connections. Model CRD-2WT’s inlet or outlet duct connection is made on top of the damper.
Power management company Eaton announced the launch of its heavy duty safety switches with surge protection, the latest in its portfolio of switching devices. Combining Eaton’s safety switches with integrated surge protective devices (SPD) courtesy of the Eaton SP1 and CVX series, the company said this packaged solution provides endusers with better performance than externally mounted devices, resulting in a completely wired, UL®-listed solution and better protection for connected equipment.
Trane announced the availability of its XR16 low profile side discharge air conditioning unit for split ducted systems. This high-performance, low-profile unit features a side discharge, making it ideal for difficult-to-install applications or in tight space requirements where vertical discharge units prove less than optimal.
Ruskin says it new EME720 7-in horizontal louver features 56% free area and combines a continuous-blade architectural appearance with the performance of a wind-driven rain-resistant louver. The louver’s architectural mullion is recessed, notched in the blade, and utilizes drain pockets allowing water to drain away while contributing to an appearance of one continuous louver.
Multi-Wing launched ƐPS™ Fan Blade Extensions. With bristles on the end of each blade, the company says the ƐPS closes the gap between the shroud and the fan tip. This fan blade extension minimizes turbulence in the blade, improves fan performance, and reduces noise.
Ruskin model DFD-LP Low Profile, Low Pressure Drop Dynamic Fire Damper is designed for dual directional air flow. The damper is constructed with an integral sleeve/frame and an aerodynamic shaped blade for high-velocity applications.
Larson Electronics has released a 24-in explosion proof ventilation fan ideal for areas where flammable gases, vapors, or finely pulverized dusts may exist. The EPF-HPSM-24-480V high-pressure explosion proof ventilation fan from Larson Electronics features three spark resistant cast aluminum blades that move stale air at a rate of up to 6,860 cubic ft per minute. The frame is made of heavy duty 14-gauge steel that is completely arc welded with tubular supports. This unit is rated for use in Class 1 Group D and Class II Groups F and G hazardous areas.
Engineered Systems magazine’s June 2019 issue examines the role of HVAC systems and power in colleges and universities via the decentralization of a Missouri college’s central boiler plant, an examination of ventilation considerations in Group R-2 facilities, the steps engineers should consider when overcoming unanticipated boiler room setbacks, common calculations and considerations regarding NFPA 92, and much more.
