Tru-Temp DX Packaged Chiller Systems combine all components of a chilled-fluid system into a single enclosure, using direct-expansion refrigeration to absorb heat from water, glycol or brine.

Northern Air's DX (direct-expansion) PCA units are described as the most common PCA design in use today, delivering a constant 32-34°F (0-1°C) supply air to parked aircraft.

The AHU (air handling unit) PCA system is an extremely lightweight unit positioned as a replacement for centralized PCA systems.

Tru-Temp Packaged HVAC Units house all components (evaporator, condenser, compressor and heater) in a single outdoor cabinet built to operate in harsh, rugged environments.

Tru-Temp DX Split HVAC Units separate the system into an indoor cabinet (evaporator and heater) and an outdoor cabinet (condenser and compressor), designed to operate from -40°F to 131°F.

The CW+DX Hybrid PCA system combines chilled water with direct expansion and is positioned by Northern Air as the superior choice for hangar operation.

Northern Air's oil & gas HVAC systems are explosion-proof units built for hazardous environments in oil, gas, refining and petrochemical facilities.

Tru-Temp Mobile Medical Environmental Control Units provide critical equipment cooling and air conditioning for mobile medical applications, mounted on semi-trailers to serve remote and underserved communities.

Northern Air's military PCA units are high-pressure, self-contained systems configurable for hangar, shelter or remote operation.
