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.
Desert Aire has unveiled its new Q-Pump Inverter + that uses a variable speed driven compressor. The Q-Pump Inverter + is incorporated into DOAS that are being installed on a geothermal, hybrid or tower/boiler loop, and delivers conditioned air to a building optimizing the performance of its heating and cooling systems. The Q-Pump Inverter + replaces Desert Aire’s Q-Pump.
FS-Elliott Co., LLC has released the R1000, the newest addition to the Regulus® control system line. The R1000 introduces new features that together enable plant operators to deal with energy costs.

Lennox has expanded its light commercial Raider® rooftop unit line to include new 7.5- to 12.5-ton models, adding to its existing offering of 3- to 5-ton units. Designed for compatibility with many replacement installations, Raider units are built to fit the most curb sizes virtually eliminating the need for an adaptor curb on many replacement jobs. Available in gas/electric and electric/electric models, 3- to 12.5-ton units offer efficiency levels of up to 13 SEER, 11.5 EER, and 13.2 IEER.
Bitzer is now offering a range of compressor units for use with the natural refrigerant ammonia (R717). The Bitzer ammonia compressor packs (ACP) are available with a capacity range of 100 to 450 TR. The modular compressor units comprise up to three compressors. For higher capacities, as many as three compressor packs can be connected (up to 9 compressors) and connected to a single controller, increasing the overall capacity up to 1,200 TR. The company says this is ideal for industrial systems.
Johnson Controls introduced the Luxaire® Ovation™ Ultra High Efficiency Packaged Unit. The combination of the unit’s two-stage compressor, VFD, high-efficiency indoor/outdoor coil, and premium-efficiency indoor/outdoor motor, delivers up to 18.1 SEER and 14.35 EER.
