Firmly grounded in Daikin’s oil-free, magnetic bearing compressor technology, the Magnitude® WME Generation 2 builds on its performance with a redesign of the single compressor WME models from 400 to nearly 800 tons. The company says the Magnitude WME Generation 2 offers improved performance (especially in harsher climates), lower operating costs, and improved first costs.
Roberts-Gordon LLC recently reintroduced the GORDONRAY® DF two-Stage, unitary low-intensity infrared heater. Due to the ability to fire at two distinct rates, the company says its GORDONRAY® DF provides energy efficient heat that can effectively adjust to sudden high heat-loss conditions or economically maintain steady comfort levels.
