Modular Walkin Chamber

CME’s Modular Walk-In chamber offers unmatchable flexibility in installation. The panelised construction is engineered to perform at demanding testing conditions offering highest reliability and performance. Besides modular construction, we also offer Walk-In chamber made from welded rigid panels.

Overview

CME’s Walk in chambers are designed for simulating, monitoring & control of environmental conditions like temperature & humidity. All these chambers are double walled & modular in construction, easy to assemble at site. They are available in standard sizes & can also be tailor made to suit specific requirements. Forced air circulation with the help of fan blower maintains uniform conditions. Use of intelligent control systems & dedicated software requirements greatly enhances the performance. These chambers can be provided with standby refrigeration & humidity systems (optional) for uninterrupted functioning.

Types of Flooring

Step-In Flooring

The Walk-In chamber is built on an existing floor with insulation of 150 mm – 200 mm. Step-In flooring is ideal for those testing applications where the test specimen is light in weight and offer easy mobility in placing it inside the test space.

Step Less Flooring

For the whole vehicle testing or to conduct test on a heavier specimen, the Step Less flooring is used as it will be easier to drive them from the ground to the test space. The floor is seamless made by inserting wall panels into it and is insulated from underneath.

Got Technical Question!

Controller

Communication

Web Server

Built-in web server allows remote view or control from any internet connected PC, tablet or smart phone

NI Lab view

The communication which used is MODBUS RTU protocol, which is an international standard for communication in process instrumentation and automation. Necessary changes to be made in the user’s software to communicate this in MODBUS RTU universal protocol. This feature can be used manual mode only.

Hardware

Enhanced with modular controller integrating multi-zone PID control and data acquisition. SIMATIC programmable logic controller. Touch screen controller, PLC and other controller components are of a generic make with an OEM software. Free software upgrades up to one year.

Memory

SD card of 2GB memory will store all the test program data and also the diagnostic data. This card is accessible by USB and Ethernet.

Digital Events

1 digital output for switching test specimen via potential free contacts, load max. 24 VDC, 5A

Programming & Report Generation

Programs

99 independent programs can be stored with name and number. Each of these programs have segments which can be looped to a previous segment and repeated up to 999 cycles, creating almost unlimited number of segments The chamber can be operated in manual mode, where the set point can directly be changed in the home screen The ramp rate can be set as a value in °C/min or ramp time Graphical representation of the temperature program The time is logged only when the set valve is within the band.

Trend Graph

Real time trend graph for temperature set value, temperature process value, humidity set value and humidity process value. Options of zoom in/out, pan and individual plot selection

Safety & Security

Security

Multi level security of guest, user, admin and factory level users with individual password protection All settings can be reset to factory defaults using admin login

PID

6 zone based PID’s with auto recall of PID based on type of program, segment and zone can be set. Each of these PID’s can be set by using the auto tune feature or manually based on user’s requirements.
