Environments don’t get any harsher than this. Nordic Air’s Military ECUs are designed to take the most severe abuse. Heavy duty, but lightweight aluminum construction. This versatile compact dual capacity 18K / 9K ECU is designed for easy handling and hook up. The dimensions of Nordic Air 18K / 9K is the same as the existing 18K equipment found in the field. This allows for easy change out. This versatile compact ECU will operate in (2) cooling modes merely by turning a switch. High Cool: 18,000 BTU. Low Cool: 15,000 BTU. A canvas cover is provided for the condenser for transport or storage. A liquid sight glass is visible from the outside of the enclosure so refrigerant level can be determined without opening up the ECU. Access ports for reading system pressures and refrigeration charging are located outside the enclosure. There are four handles provided for lifting. An hour meter is provided for preventive maintenance planning. Easily accessible circuit breakers for power and control voltage are provided. A phase monitor is provided to prevent damage because of an improper power supply connection. Most spare parts i.e. compressor and electrical components are COTS. Front or side power hook up points.


Mil-Spec and COTS designs for cooling and heating Tents, Shelters, Vans and ISO Containers.
