In a nutshell, the Rochem Gas Turbine Cleaning Product Range has been created to take the stress and worry out of industrial gas turbine cleaning. It can be customised to your specific requirements and is suitable for use in hazardous areas including gas platforms. With the option to choose whether you conduct an on-line or off-line clean each time, this tried and tested technology keeps you in control while enabling efficient and reliable cleaning. You can also choose a standard set up or opt for customisation to suit your specific requirements.

The Rochem Gas Turbine Cleaning Product Range is comprehensive and fully self-contained with the option for either a mobile or static set up. Simple to use, the system achieves exceptional results with very little effort.

This product range supplies gas turbine wash nozzles and the supporting hardware to enable on-line and off-line gas turbine cleaning. Once installed, these nozzles spray atomised water and detergent (if desired) into the compressor. This water then safely and effectively removes foulants which otherwise interrupt airflow and cause a drop-in efficiency.

The nozzles deliver a carefully measured, safe and effective droplet size which is large enough to ensure a thorough clean while remaining small enough to avoid erosion. Wash fluid is injected through the lowest number of injection nozzles possible while still fully wetting the compressor blades.

To keep the clean as cost effective as possible, we’ve also carefully calculated how to achieve the maximum wash fluid/blade contact time while keeping the volume of water/detergent to a minimum. This effective cleaning process can be conducted during normal use (on-line) to achieve a clean without interrupting productivity, or for a more thorough off-line clean at your discretion.

Finally, to ensure faultless installation and first use, each Rochem Gas Turbine Cleaning Product Range is fully factory tested before dispatch and designed for quick and easy installation at your facility.
