Walkin Test Chamber

CME's Modular Walk-In chambers provide unparalleled flexibility during installation, with panelized construction engineered for optimal performance under demanding testing conditions, ensuring the highest levels of reliability and performance. In addition to modular construction, we also offer Walk-In chambers made from welded rigid panels.

Overview

CME's Modular Walk-In chamber provides unparalleled flexibility in installation. The panelized construction is engineered for optimal performance in demanding testing conditions, offering superior reliability and performance. In addition to modular construction, we also offer Walk-In chambers made from welded rigid panels.

CME's Walk-In chambers are designed for simulating, monitoring, and controlling environmental conditions such as temperature and humidity. All these chambers feature double-walled, modular construction that is easy to assemble on-site. They are available in standard sizes and can be customized to meet specific requirements. Forced air circulation, facilitated by a fan blower, ensures uniform conditions. Intelligent control systems and dedicated software enhance performance. These chambers can be equipped with optional standby refrigeration and humidity systems for uninterrupted operation.

Types of Flooring

Step-In Flooring

The Walk-In chamber is installed on an existing floor with 150 mm – 200 mm insulation. Step-In flooring is suitable for applications where the test specimen is lightweight and requires easy mobility within the test space.

Step Less Flooring

For testing entire vehicles or heavier specimens, Step Less flooring is used for easier access from the ground to the test space. The seamless floor is created by embedding wall panels and is insulated from below.

Got Technical Question!

Controller

Communication

Ethernet

Ethernet capability to remotely monitor and control the chamber.

USB

USB Type-A host port to connect a keyboard or mouse or download CSV data via pen drive [max 2GB] USB Type-B data port for connection to PC for software upgrade and access memory card storage

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.

Process Mimic

Graphical representation of the working of the chamber, with live status of all the components, including the current temperature/humidity process values, compressor suction/discharge pressures and return gas temperature
