List of refrigerants
An investment in gas sensors – a requirement or an unnecessary cost?
COST In refrigeration and heating installations, efficiency in the operation of the system depends on its gas charge, a leaking system will incur additional costs. Firstly, it needs to work harder to produce the same cooling / heating effect which…
Legal standards and directives
LEGISLATION 1. Safety at Work Occupational and ‘safety at work’ type legislation require that workers are not exposed to harmful gases, including refrigerants, above the recommended limits. These are normally policed by responsible bodies such as the Health and Safety…
Impact on the natural environment
ENVIRONMENTAL IMPLICATIONS Minimising leaks of damaging gases to the atmosphere has become increasingly important in the last 10 years. Research in the 80’s proved that man-made substances including CFC’s, HCFC’s, and halons cause severe depletion of the Ozone layer. Each…
Types of sensors
GAS SENSOR TECHNOLOGIES CATALYTIC Catalytic sensors (sometimes called a bead or pellistor type) have been mainly used for combustible gases including ammonia and are the most popular sensor for this application. The Gas Sensor functions by burning the gas at the…
