Bitzer
The Octagon Varispeed series is Bitzer’s first line of intelligent compressors. According to company sources, its highlight is the integrated suction-gas-cooled frequency inverter. This system significantly lowers operating costs and ensures reliable and effective performance, even at high ambient temperatures. The maintenance-free frequency inverter and the easy installation and configuration are just some of the many benefits offered by the Bitzer compressor series. Bitzer’s Varispeed series is UL approved and can be applied with R134a, R404A, R507A, R407C and R22. bitzer.de/    circle 153

Heatcraft
Kysor/Warren’s innovative distributed scroll system has been redesigned with serviceability and improved life cycle climate performance (LCCP) in mind. Sources say the distributed scroll system reduces refrigerant charge up to 40% compared to a traditional centralized rack system and features a 35% reduction in brazed joints, drastically lowering the potential for leaks compared to the prior generation product.  The space saving design maximizes merchandising space by eliminating the need for a machine room.  Additionally, the reduction of field brazing joints results in easier installation.  Hinged front doors provide quick access to scroll compressors.

Daikin AC
Daikin AC introduces the new 8-zone multi-split system (RMXS48LVJU) targeting light commercial and whole-house residential markets. The 4-ton 8-zone system is an energy-efficient (up to 18.8 SEER, and 11.3 HSPF) high-capacity heat pump system incorporating Daikin’s famed VRV technology, with the ability to connect from 2 to 8 indoor units with a single, compact outdoor unit. The inverter-driven compressor provides precise capacity adjustments for efficiency and accuracy in comfort control, and allows long piping lengths (up to 180-ft. to the branch provider, over 440-ft. total loop) for added installation flexibility. daikinac.com     circle 160

 

LG
LG Electronics USA introduces a multi-zone duct-free split heat pump system that provides heating and cooling for up to eight separate zones, while increasing overall capacity by up to 50% compared to previous LG multi-zone models.  
The new LG “Multi F Max” system (LMU540HV) increases capacity to a nominal capacity of up to 54,000 btuh, from the previous multi-zoned system capacity of up to 36,000 btuh.  Adding branch distribution to LG’s Mult F product family also effectively doubles the number of potential temperature control zones available, now offering up to eight individual zones for customized comfort.  lghvac.com      circle 161
