Mitsubishi Electric Trane HVAC US Introduces PEFY-OA Ducted Outside Air Unit

SUWANEE, Georgia – August 15, 2019 – Mitsubishi Electric Trane HVAC US (METUS), the exclusive provider of Zoned Comfort Solutions® and leading supplier of Variable Refrigerant Flow (VRF) heating and cooling systems, introduces the PEFY-OA Ducted Outside Air Unit.

The PEFY-OA is a high-performance indoor unit that improves comfort by pre-treating and filtering outside air before delivering it to each zone. Available in 36,000, 48,000, 72,000 and 96,000 BTUH capacities, the PEFY-OA has three modes of operation: cooling, heating and fan only. The PEFY-OA heats or cools incoming outside air based upon the ambient temperature and set point, and provides discharge air temperature control. Compatible with CITY MULTI® systems, including other indoor unit styles, the PEFY-OA helps building owners, engineers and architects increase indoor air quality and meet requirements for ventilation in a variety of commercial applications.

“We’re constantly researching innovative ways to help HVAC specifiers provide increased indoor air quality for their customers,” said Kevin Miskewicz, director of commercial product planning for Mitsubishi Electric Trane HVAC US. “The PEFY-OA is able to temperature control fresh, outside air and can be used in conjunction with other indoor units within a CITY MULTI® system, leading to a more seamless install.”

The PEFY-OA is an ideal choice for office buildings, schools, hotels, assisted-living facilities and other applications where ceiling plenum space is available.
