The mobile generators have been validated and are now available to rental operators and customers.
Berner International Corp. has introduced a patented Venturi-style heater design, which the company says will offer a more aerodynamic, electric heated air curtain with improved air performance efficiency by up 40% The VTH electric heater combines a hemispherical heating element array with an innovative mounting strategy at the blower inlet. The patented design uses the Venturi effect to draw air through the heating element via the blower inlet before it enters the discharge airstream. The discharge airstream velocity remains unobstructed in a near 100% efficient heat transfer, full laminar pattern for an optimum aerodynamic performance. Company officials said that this creates a near perfect environment-separating air seal across any open doorway while providing auxiliary heat, as needed.
Danfoss says it has developed the new TU with F-charge TXV to help OEMs meet the new U.S. Department of Energy commercial refrigeration energy efficiency standards. The new F-bulb charge delivers low superheat in low- and medium-temperature refrigeration ranges, includes asymmetric ballast material that is proven to deliver more stable temperature control and, like all Danfoss TXV bulb charges, is HCFC-22 free.
Harsco Corp. announced a planned market introduction of its all-new NURO™ touchpad control platform for its Patterson-Kelley boiler product line. Developed exclusively by Harsco, the proprietary NURO™ is the latest in the company’s Patterson-Kelley line of customer-focused boiler product innovations, including the introduction last year of its energy-efficient SONIC™ stainless steel boiler and its MACH N’ROLL™ domestic hot water heating system.
FS-Elliott Co. recently launched their Polaris+ series. Building on the design of FS-Elliott’s original industrial compressors, the Polaris+ line incorporates several new product advancements aimed to increase reliability and efficiency while maintaining low cost of ownership. The new Polaris+ series consists of five models with flows ranging from 900 to 11,500 icfm, 250 to 3000 hp, and pressures up to 150 psig.
Rinnai says it has introduced the first tankless water heater in the industry that allows for both concentric or twin-pipe PVC venting from the same unit. These new Ultra Series models RUC98i and RUC80i feature a built-in system, which according to the company, allows for maximum flexibility because the unit specified or on-hand will be compatible with whichever venting installation is preferred or required when it arrives on the jobsite.
Daikin Applied claims its Magnitude WMC chillers with RapidRestore™ gives owners peace of mind during a power loss. The new RapidRestore feature gives the Magnitude WMC a compressor start time of 43 seconds and it fast loads to 80% capacity within 120 seconds after power is restored.
Greenheck introduced the Model AFL-501, a 5.5-in deep, severe duty aluminum louver that protects exterior wall penetrations on FEMA 361 or 320 compliant storm shelters or safe rooms. According to the company, the Model AFL-501’s design incorporates inverted V-style blades that lend high free area, excellent resistance to water penetration and very low airflow resistance, while providing maximum protection against extremely high wind loads and wind-borne debris.
