WAZZLE Modular Walk-in chambers

Without compromising ACS's high standards of quality and reliability, we wanted to reduce delivery times to twelve weeks or less and avoid the costs of design and engineering normally.

The solution is the WAZZLE a cost effective modular design compromising the four basic elements of a walk in chamber that can be mixed and matched to provide a configuration to suit the majority of requirements:

• Plant Unit


• Air Handling Systems


• User Interface


• Vessel Construction

Plant Unit

Comprising of the refrigeration equipment and humidification systems required for the control of the temperature and air humidity inside the walk- in chamber. The basic version requires either mains water or tower water for cooling.

Air Handling Systems

Powerful fans draw the chamber air across the heat exchangers for cooling and dehumidification, heaters and control sensors before reticulating the conditional air back into the chamber. A Pt100 sensor (temperature) and a capacitive probe (humidity) is used for control.

User Interface

The control system interface is placed near the door for all the versions of the walk-in chamber. It comprises of :

• Emergency STOP push button


• Touch panel programmer/controller


• Serial Interface RS 232/422


• Software + personal computer ( optional)

Vessel Construction

Vapour tight prefabricated panels suitable for multiple assembly and take down operations, AISI 304 interior, blue plastic coated zinc or steel exterior. Insulation thickness: 120 mm.
