HAZcool®

HZ6 3-Piece Split

Air Conditioning System


This system is designed to control the internal temperature of modular / containerised buildings where the module interior is separately maintained as a non-hazardous area by means of over-pressurisation.

This ATEX compliant system is designed and manufactured use in hazardous, explosive areas (zone 1 / zone 2).


The system's configuration offers versatility for various module layouts. The main parts of the system can be located to suit space requirements and availability of locations for positioning equipment.


The system consists of three main parts; a 1 off evaporator unit complete with thermostat, a 1 off compressor / control panel unit and a 1 off ATEX compliant 316L stainless steel marine condensing unit. The evaporator unit can also be supplied in stainless steel for corrosion resistance. This system is suitable for use with power supplies ranging from 380V to 420V at 50Hz and 440V to 480V at 60Hz via an integrated voltage selector switch.


The HZ6 systems are easy to install and maintain. Controls are easy to use and maintain reliable automated room-temperature control.
