In recent years there has been a rising trend in the outbreak of Legionnaires' Disease, associated with wet cooling systems (cooling towers and evaporative condensers), water storage tanks etc., resulting in serious cases of infection, fatalities and considerable public concern.
The Health & Safety Executive provides an 'Approved Code of Practice and Guidance' on the control of legionella, part of which includes the implementation, management, monitoring and recording of the precautions to significantly reduce risk - and this is where Hanwell Instruments excel.
We provide invaluable monitoring for water facilities and storage ensuring, for example, that the temperature is maintained below 20 degrees C for cold water and above 60 degrees C for hot. Further, fluid flow levels, chlorine levels and ultra violet (UV) irradiation water treatment can be monitored and effectively maintained via online reporting and archival storage of conditions, utilising imported colour CAD drawings providing easy-to-read displays.
Maximum accuracy is maintained by affixing telemetry monitoring units on to carrying pipes and placing sensors directly in the waterflow. However, where an installation is within an underground conduit or subterranean walkway, we would first complete a radio survey to determine the appropriate action; it may be necessary to mount the sensor remotely from the telemetry unit.
