Eaton Compressor has released its all-new 1,200 cfm refrigerated air dryer, an energy-efficient air dryer system that comes with an aluminum refrigerated air inner cooler. The refrigerated compressed air dryer purifies compressed air by chilling to condense moisture. It has a design condensate which is drained and carries out oil and dirt particles away from the air.
Rotobrush® International LLC has launched the BrushBeast, which was designed with a 90% increase in vacuum power. The company said that the BrushBeast allows for easy maneuvering into tight areas such as attics and crawl spaces.
Lennox has expanded its Energence® rooftop line with new ultra-high-efficiency models. Lennox’ ultra-high-efficiency Energence units feature efficiencies of up to 21.5 IEER and 13.9EER resulting in overall lower operating costs and service, which the company says contributes to the lowest total cost of ownership. Energence ultra-high-efficiency units are designed to offer customers energy savings with features such as the Advanced Cooling System and the DirectPlus™ blower system. In addition to sustained savings, the Energence ultra-high-efficiency lineup exceeds ASHRAE 90.1 minimum standards by 92%, exceeds CEE Tier 1 and 2 efficiency minimum requirements, and qualifies for many potential utility rebates and incentives, while also providing additional options to meet California Energy Code Title 24.
