Crowcon Xgard ESU Environmental Sampling Unit

The Crowcon Environmental Sampling Unit (ESU) is a unique product that provides a cost-effective solution for monitoring high-density gases such as chlorine, sulphur dioxide, and flammable vapours in environments where conventional sensors cannot be placed.

The sampling chamber is fitted with an electric fan, which draws an air sample via a pipe.

Xgard gas detectors are fitted to the chamber to monitor for flammable or toxic gases.

Low purchase and maintenance costs

• The ESU is ideal for monitoring large enclosed areas such as chlorine stores. One unit can monitor up to 12 metres of pipe, eliminating the need for multiple sensors mounted at floor level.
• Fewer sensors mean lower maintenance costs.

Adaptable installation options

• The ESU is supplied with a range of accessories to suit any installation requirements. It can monitor from a single point, along an entire floor space, or even in areas subject to flooding, such as a wet well.
• The ESU’s rugged design and high-impact ABS enclosure make it suitable for harsh environments.

Wide range of sensors

• The ESU is used with Crowcon’s versatile Xgard detectors, which enable the monitoring of a wide range of gases.
• A hazardous area certified version is available for safely monitoring flammable vapours.

High integrity design

• The ESU is designed to connect to Crowcon’s class-leading Gasmaster or Vortex control systems. These systems display the gas level and monitor the ESU fan to ensure it has not slowed or stopped.
• An alarm is raised in the event of a gas leak, fan blockage or fan failure.
