Climatic Chamber - Walkin

Home Appliances especially refrigerators are constantly under scanner to be more energy efficient, reliable and environment compliant. This has led many manufacturers to bring new innovations in their product line-up. Many such manufacturers are using CME chambers to test their new products for its cooling performance, energy efficiency and construction reliability under various environmental conditions.

The featured Walk-In Chamber has test space capacity of 25,344 Litres, temperature range of -15°c to 50°c and humidity range of 10%RH to 98%RH. The test chamber has two port holes for live product testing with rate of change of heating/cooling 0.2 °c (with mass) and controlled airflow rate of 0.5m/s. The energy efficient chamber is customisable as per customer’s requirement with 24X7 customer support and is available in 18 countries.

We ensure safety while you are testing your product. Safety systems like fire suppression system, gas monitoring systems and safety evacuation of the gases from the system.

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.
