Heating, Ventilation and Air Conditioning (HVAC) is the technology of indoor environmental comfort. The main functionality of HVAC is to provide safety, optimal wellbeing, and cost-efficiency. For this to happen successfully, determining the carbon dioxide and refrigerant gas content of the room needs to be applied to measure the air quality.

The iR-gas Flush Mounted Carbon Dioxide (CO2) is a 3 wire 4-20 mA Non-Dispersive Infrared (NDIR) Carbon Dioxide (CO₂) sensor. It gives a 4-20 mA o/p over the range of the sensor. Designed for applications where low-profile intrusion into a room space is required.
Our refrigerant gas detector with an infrared sensor, “iR-gas” functionality, is to detect the presence of the target refrigerant gas in the air surrounding it. This refrigerant gas detector with an enabled infrared sensor is designed to connect to a GDA gas detection controller or similar BMS system. This is to control alarm systems and/or ventilation to reduce gas loss and potentially harmful situations.
The refrigerant gas detector enabled with an Infrared Sensor, contains a Non-Dispersive Infra-Red (NDIR) gas sensor, operating via natural diffusion. This sensor is designed to give long service life under normal ambient operating conditions. Also, this sensor technology allows greater accuracy and lower cross-sensitivity to other gases, majorly reducing false readings when other gases are present.
Our iR-gas refrigerant gas detector has the following technical features: Range: 0-1000 ppm; NDIR Sensor, Output: 4-20 mA, 0-20 mA, 0-5 VDC or 0-10 VDC, Alarm Relay, Power: 24 VDC 3-wire powered, Factory set alarm: 250 ppm, Factory Calibrated Output set to 4-20 mA.
Range of Refrigerant gases: r134a, r410, r32, r123, r22, among others.
Our refrigerant leak detector with an infrared sensor functionality is to detect the presence of the target refrigerant gas in the air surrounding it.

Our flammable gas detector GTD-3000Ex has been developed to detect flammable gas leaks from industrial sites, factories, gas storage, and manufacturers that produce or use flammable gases to prevent accidents.
The GTD-3000Ex flammable gas detector is installed in areas where it is a risk for flammable gas exposure and is continuously monitored. It displays measurements on built-in displays (LCD) of the detector and provides an Analog 4~20 mA standard output signal. Also, for Analog 4~20 mA standard output, output signal transmission length between detector and receiver can be connected up to 2,500 m. The GTD-3000Ex flammable gas detector must be used at a height below 1,000 m above sea level.
