Johnson Controls has extended its TempMaster® line to include OmniElite™ single package rooftop units. Available in 50- to 65-ton cooling capacities, the company says its new units offer a footprint up to 20%smaller than competing units, double-wall construction, single-point power connection and efficiency ratings that exceed ASHRAE 90.1 standards.
Kohler Power Systems is launching an all-new line of large natural gas generators designed specifically for standby, prime, or continuous power applications in the North American market. The new line of large gas gensets, which will be available in nodes ranging from 425 kW to 1,300 kW, meet Environmental Protection Agency (EPA) operational requirements and offer advanced control and monitoring capabilities through the Kohler Decision-Maker® 8000 digital controller.
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.
