Modular Walk In Chambers - Wazzle

Without compromising our 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 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:

• Plant Unit.
• Air Handling System.
• User interface.
• Vessel Construction

Plant Unit

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

Air Handling System

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) 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:

• 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 zincor steel exterior. Insulation thickness: 120 mm.

Advantages

• Reduction in the lead-time for chamber production.
• Improved cost-effectiveness of the equipment.
• The facility to use the same combination of plant unit and air handling system on walk-in chambers which have:
  • Different geometry.
  • Different temperature rates.
  • Different minimum and maximum temperature limits.
  • Different thermal load.
• Easy to assemble on site.
• Easy to disassemble, relocate and rebuild the equipment, if necessary.
• Possibility to upgrade or refurbish existing facilities by using the plant unit / air handling system / user interface without requiring major reconstruction work.
