HAZcool®

HZ2 Rooftop Packaged

Air Conditioning Unit


This unit controls the internal temperature of a non-pressurised module where the external and internal areas are classified as hazardous.

This ATEX compliant unit is designed for use in hazardous, explosive areas (zone 1 / zone 2). Designed to be externally mounted on the roof, the unit is cased in stainless steel for corrosion resistance.


As the unit only requires a connection to roof penetrations or inlet / outlet ducts, this configuration requires no internal space within the module / cabin offering a versatile solution for various module / cabins.


There is no external piping and the units are supplied pre-charged with refrigerant and ready to run. Units are designed for easy installation and do not require specialist installation. The only client interface required is to bolt the unit in place, connect the ducting, power supply and external controls (in some cases). Once installed the controls are easy to use and maintain reliable automated room-temperature control.
