Electronic Door Lock

Chamber door is locked using an Electro-Magnetic door lock. During testing, the chamber may contain hazardous gases released from the batteries and the lock prevents users from accidentally opening the door.

Status Indicator and Alarm

A visual status indicator can be used to monitor the chamber’s status from a distance. A red lamp flashes during any faults in the system along with an audible sound which can quickly alert operators.

Retaining Clamp for Port Hole Plugs

Due to pressure differential that may arise between the chamber test space and the ambient atmosphere during testing, the port hole plugs are secured using a retaining clamp.

Temperature Limited Heaters

Heater surface temperatures are maintained below the auto ignition temperature of the combustible gases that may be released from the batteries, thereby preventing ignition.

Mechanical Door Latches

Chamber Door is secured with sturdy mechanical latches on both sides. Any increase in pressure inside the chamber is safely contained.

Gas Monitoring

Concentration levels of Carbon Monoxide (CO) and Hydrogen (H2) are monitored using a sampling system with electrochemical sensors.

Fire Detection and Alarm System

Fire detection is possible by monitoring the carbon monoxide levels or by a sudden increase in chamber temperature. Once fire is detected, an audio-visual alarm can be triggered for alerting the operator.

Fire Suppression/ Extinguishing

When a fire is detected inside the test space, it is extinguished by flooding the test space with carbon dioxide (CO2) or Nitrogen (N2).

Chamber Inertisation

After the completion of a test, the chamber may be intertised with nitrogen (N2) in order to flush out any hazardous or combustible gases and reduce the oxygen concentration before opening the door.

Oxygen Measurement

Oxygen measurement is used in conjunction with the chamber inertisation to monitor the concentrating levels and control the nitrogen flushing.

Pressure Relief Vent

A pressure relief vent is provided to equalize the pressure in the chamber during inertisation or flushing of CO2.

Burst disk

In the case of an explosion, there is a sudden release of gas and increase of pressure inside the chamber. A Burst disk is provided to release this pressure into an exhaust duct.
