WZH – WZT

Modular design is the solution. 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:
  • Cooling Unit.
  • Air Treatment Unit
  • User interface.
  • Test room
The modular walk-on line includes 4 models according to their useful capacity: Compact (10 m3), Medium (16 m3), Large (30 m3) and Extra Large (40 m3).
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).
Cooling 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 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) 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).
Test room.
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.
CONTROL SYSTEM: an innovative software 
ACS modular walk-in chambers are now equipped with the new all-in-one software MyKratos™ allowing to manage, monitor and assist the chamber through mobile and desktop devices, using WiFi, Ethernet, or mobile network. No additional hardware or software required.

The chamber is equipped with a PLC (Programmable Logic Controller), used to manage all chamber functions and safety interlocks. A special device is used to control the chamber via “mobile” devices, such as Tablets and Smartphones, or to establish a remote Internet comnnection. The HMI system consists of an on-board panel  and a Remote connection control (MyKratos™ and MyAngel™). The system can connect several chambers in cluster mode at the same time and can provide a common supervision from a centralized point (option: MY KRATOS MULTICHAMBER S/W FOR MULTICHAMBER REMOTE CONTROL BY PC) MyKratos™ includes MyAngel24™, our remote teleassistance 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.
