Project
Redlands Research Centre.
A compact, highly accurate system for injecting methyl bromide into six research chambers.
Separate test chambers, each dosed under control.
The size of each chamber. Small volumes leave no room for error.
Litres of boiling water. The heating is completely dry.
It used to take a vat of boiling water.
Methyl bromide has to be turned from a liquid into a gas before it is injected. Earlier machines did that in large, pressurised vats of boiling water. Scalding and pressure hazards were accepted as part of the job. We designed them out.
Previous designs
Large, pressurised vats of boiling water supplied the heat. Scalding and pressure hazards were believed to be unavoidable.
GasApps design
A custom integrated electric heater and heat exchanger. No boiling water and no pressurised vat, with better thermal efficiency and precise temperature control.
One controller. Six chambers.
Mass flow meters measure the gas going into every chamber, continuously, so each dose is controlled and every run is recorded.
Built in, not bolted on.
PLC programming
Custom control logic, written by GasApps, runs every sequence automatically, with safety interlocks built in.
Omron touchscreen
An industrial touchscreen shows every system parameter in real time and logs the history of each run.
Emergency stop and alarms
A clearly marked E-stop within reach, tied into an alarm system with visual and audible warnings for critical faults.
Mass flow meters
High-accuracy meters measure and control gas throughput continuously, for consistent dosing and clear consumption records.
We didn't just meet the safety requirements. We set a new standard for the job.
