HAZcool®

HZ11 1-Piece Packaged

Air Conditioning Unit


This system is a self-contained, packaged unit, pre-commissioned and factory tested. Units are designed for a straight-forward installation and do not require specialist installation.

This ATEX compliant system is designed for use in potentially hazardous, explosive atmospheres (zone 1 / zone 2). The system is cased in 316L stainless steel for corrosion resistance and standard components are used to ensure spare parts are readily available.


The only client interface required is to hook-up the electrical and inlet/outlet ducting connection (by others). Once installed, controls are easy to use and maintain reliable automated room-temperature control.
