HAZcool®

HZ10 4-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. This system is intended for facilities with two or more separate rooms with individual temperature control requirements. These are controlled by individual thermostats, linked to a single compressor which modulates to meet the real-time system heat load requirements.


The system consists of four main parts: 2 or more internal evaporator units, 1 off compressor/control panel and 1 off ATEX compliant 316L stainless steel marine external condensing unit. The evaporator units can also be supplied in stainless steel for corrosion resistance. Once installed, controls are easy to use and maintain reliable automated room-temperature control.
