Mitsubishi's commercial 24,000 BTU hyper-heat wall mounted single zone heat pump (PKA-AK24NL & PUZ-AK24NLHZ) is part of Mitsubishi's P-series. This single zone unit is perfect for server rooms, daycares, churches, small offices, and other business and commercial applications. This system can heat down to -13F.

Mitsubishi Electric created the P-series systems for commercial applications. P-series systems like the PKA-AK24NL & PUZ-AK24NLHZ are built with more durable materials, meant to survive through dirtier, high trafficked environments. This system uses the new R454B refrigerant.

This 24,000 BTU wall mounted single zone heat pump is super efficient and built to make sense for your business. It provides low ambient cooling down to 0 degrees Fahrenheit, and can cool continuously for 24 hours in the harshest conditions.
