Air Conditioning Gas Monitoring Systems

Gas Detection Solutions for all Air Conditioning Environments

Air conditioning gas monitoring has a diverse application range. Most public areas that have a positive HVAC supply will require gas monitoring by regulation. One of the most common applications is to monitor an air supply to make sure that CO2 levels are identified at dangerous exposure levels
Our HVAC gas monitoring systems identify refrigerant leaks in the pipework and ducting of the HVAC unit. We can mount in situ and continuously monitor an air supply given to a required area such as class rooms, shopfloor and laboratories as an example. We can monitor all the major refrigerant gas types such as R123, R410, R404, R407 and R134a however this list is not exhaustive.

HVAC Areas Monitored

  • Classrooms
  • Offices
  • Shopfloor
  • Laboratories
  • Marine Vessels
  • Hospitals
  • Compressor Rooms
  • Apartment Blocks
  • Supermarkets
  • Shopping Centres

Flammable Gas Detection

There are also possibilities that other flammable gases can be present in HVAC systems such as Propane, we can monitor these types of flammable gases in low concentrations to allow an instant shut down of a problematic HVAC system, using any of our many output protocols such as digital, analog and RS485 signals.
Contaminants such as Particulates, Carbon Monoxide CO, Volatile Organic Compounds VOC’s can cause issues in a consumed air supply so it is important to continuously monitor for these gases and integrate our system with your new or existing ventilation system.
Our aim is to ensure a safe working environment by creating a fully monitoring gas system to your specifications and requirements

Various Control Panel options are available

Control panels are also available that cover small 4 transmitter systems up to more sophisticated 250 transmitter systems. All our control panels have internal memory to retain alarm history for trend diagnosis. All our control panels and transmitters can be connected to audio/visual indicators such as sounders and beacons which can also supply as part of a solution.

Typical question answered by our expert

There are few ways you can tell if your AC unit is low on refrigerant gas, the first is usually that the air supply from the unit will be a low flow. This then could lead to the AC unit blowing warmer air, as the refrigerant gas will not be present to absorb the heat. Generally, as the efficiency of the AC drops, you may notice a higher electrical supply consumption.

You mainly 2 types of gas detection technology to monitor for refrigerant leaks, these are semi- conductor sensors or Infra-Red inserts. Both have merits, semi-conductors are lower cost and will give you an indication of refrigerant gas in the atmosphere, but semi-conductor sensors can have cross sensitivity issues and low sensitivity at low ppm refrigerant levels. Infra-Red merits are that you can’t over saturate the sensor at high levels and accuracy at low level ppm refrigerant levels. One Infra- Red sensor negative is the slightly higher cost and gas type specific.

A refrigerant leak detector is a sensor that will detect refrigerant gas in the atmosphere, to ensure that you are alerted to rising or current alarm levels of gas which can cause headaches, nausea, skin irritation and difficulty breathing.

Refrigerant freon gas can cause severe lung issues, skin irritation, headaches, however these symptoms aren’t exhaustive. It is important that refrigerant gas is monitored to ensure you stay below the max level exposure limits.

Refrigerant gas leaks can occur from pipe degrading over time due to acid corrosion, this then allows the gas to escape the gas pipe path within the AC system. Another issue that can cause refrigerant leaks are loose fittings to the supply pipes or regulators for example.
