Amana (www.amana-ptac.com) introduced its B Series package terminal air conditioners (PTACs) and heat pumps with bent coil technology. Conventional slab-coil designs sling condensate mostly onto the condenser shroud, while the bent coil technology curves around the slinger ring, adding 25 percent more primary coil surface area, the company said. This maximizes condensate evaporation and minimizes the chance of water overflow. The company said this is why the new PTACs have higher EERs; for example, the 9,000-Btuh unit has an EER of 11.5. The units are said to be easier to service, as well, as the entire top of the bent coil shroud is easily removed, so the whole condenser coil can be cleaned. The new pull-out filter is also designed to be easy to clean or replace.

American Power Conversion (www.apcc.com) introduced the NetworkAIR FM Series of air cooling systems. These modular, floor-mount precision air-conditioning systems are designed to offer economical cooling for a variety of data environments, including computer rooms, data centers, and technology spaces.
