New Environmental Sampling Unit


(Erlanger, KY) – The new Environmental Sampling Unit (ESU) from Crowcon is a cost effective device for monitoring high density, toxic gases such as chlorine and sulphur dioxide where positioning a conventional sensor is not practical. The ESU's chamber is fitted with an Xgard detector and an electric fan draws air into the chamber via a sampling pipe.

The ESU is ideal for monitoring large enclosed areas such as chlorine stores. One unit can monitor up to 36 feet (12 meters) of sampling pipe, eliminating the need for multiple sensors mounted at floor level. The device can monitor from a single point, along an entire floor space, or even areas subject to flooding such as wet wells. Its rugged design and high impact plastic enclosure makes the ESU particularly suitable for harsh environments.

The device is monitored using Crowcon's Gasmaster or Vortex wall-mounted control panels, which show gas levels and monitor the fan to warn if it slows or stops. If there is a gas leak, fan blockage or fan failure, a local sounder is activated, alarms are indicated and outputs are sent via relays and 4-20mA or RS-485 Modbus signals. Battery backup is provided as standard, ensuring continual protection even if the power fails.
