Without compromising ATT's high standards of quality and reliability, they wanted to reduce delivery times to twelve weeks or less and avoid the costs of design and engineering normally associated with the customized walk-in chambers.

The solution is the WAZZLE; a cost-effective, modular design comprising 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:

The Wazzle line includes 4 models according to their useful capacity:

Each of these models is available in 6 versions according to cooling unit dimensions, except for Compact model which is available only in 4 versions (see the datasheet for detailed technical features of cooling units and performances).

Wazzle makes your life easier! Fast and Easy walk-in chamber assembly.

Cooling unit

Comprising 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 treatment unit

Powerful fans draw the chamber air across the heat exchangers for cooling and dehumidification, heaters and control sensors before recirculating the conditioned air back into the chamber. A Pt100 sensor (temperature) and a capacitive probe (humidity) are 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:

Test room

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.


WAZZLE chambers can also be equipped with MyAngel24™, ATT's remote tele assistance system: the chambers stay connected to the remote server 24 hours a day monitoring running conditions and any anomalies, in order to guarantee faster and more efficient service and maintenance activities. They are accessible whenever and wherever you are, from any device with an internet connection and a simple web browser.
