Crowcon F-Gas Fixed Gas Detector

Key Features

No consumable parts means the F-Gas provides many years of service with no requirement to replace to the sensor or any of its components.

Simple to test – This simplicity means the F-Gas requires only a bi-annual gas check re-calibration is only necessary if the readings are out of range.

Rapid gas leak detection provides an early warning that gas is leaking and therefor maintains systems efficiency and reduces expensive gas replacement costs.

The choice of output signals means the analogue signal can be set as 4-20mA, 0-20mA, 0-2V, 0-5V or 0-10Vdc for compatibility with almost any control system.

More F-Gas Features

  • Simple Operation – Tri-coloured LED’s indicate the operating status of the gas detector, and in combination with the function keys, facilitate simple adjustments such as zero and calibration. The analogue output signal can be set as 4-20mA, 0-20mA, 0-2V, 0-5V or 0-10Vdc for compatibility with virtually any control system.
  • Accurate & Reliable – Provides fast, stable and dependable performance with low maintenance and long life. Unlike cheaper semi-conductor type sensors the Crowcon F-Gas detector is not affected by other types of gas or changes in temperature or humidity
  • Long Life With Low Maintenance Costs – Provides many years of service with no requirement to replace the gas sensor or any other components. Requires a bi-annual gas check only. Re-calibration is only necessary if readings are out of range. Provides good protection from dust and water ingress in indoor environments.
  • Safe & Compliant – Enables F-Gas suppliers and users to comply with the mandatory European F-Gas regulations. Provides an early warning that gas is leaking and thus maintains system efficiency and reduces expensive gas replacement costs. Helps to reduce the risk of leakage of powerful ‘greenhouse gases’ into the environment

Crowcon F-Gas Gas Detector

Gas Detection For Non-Hazardous Areas

Crowcon F-Gas gas detector is suitable for use in non-hazardous areas such as plant and switchgear rooms. The Crowcon F-Gas is also suitable for protecting personnel from toxic gas risks and can help reduce the risks of powerful greenhouse gas leakage.

F-Gas detector is capable of detecting the smallest quantities of toxic gas reliably and report these findings reliably to a connected control system.

The gas concentration can be transmitted as a linear analogue current or voltage output and the following signals are available as analogue values:

      • (0) 4 – 20mA Linear; the desired operating mode can be set via a link
      • 0 – 2V Linear; the desired operating mode can be set via a link
      • 0 – 5V Linear; the desired operating mode can be set via a link
      • 0 – 10V Linear; the desired operating mode can be set via a link

How The Crowcon F-Gas Detector Protects Against F-Gases

See how Crowcon F-Gas detects F-Gases in commercial and residential refrigeration, air-conditioning systems (utilising hydrofluorocarbon gases as refrigerants or fire retardants) and high voltage electricity transmission and distribution networks (utilising SF6 gas insulated switchgear).

IR Infared Gas Detection Technology

Crowcon’s superior infrared (IR) sensor technology provides fast, stable and dependable performance with low maintenance and long life. Unlike lower cost, lower quality semi-conductor type sensors the F-Gas detector is not affected by other types of gas or changes in temperature or humidity.

F Gases & Detection

Fluorinated gases (F-gases) are a family of man-made gases that remain in the atmosphere for centuries contributing to the global greenhouse effect –  according to the European Commission the 3 groups of F-gases are hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

  • HFC 404A and HFC 134a gases are common in refrigeration systems.
  • HFC 23 and HFC 227ea gases are common in fire protection systems.
  • HFC 404A and HFC 410A gases are common in air conditioning and heat pump systems.
