Highly biodegradable natural solvent

At Rochem we specialise in gas turbine compressor cleaning and have developed FYREWASH® F2 as part of our range of cleaning chemicals. It is highly biodegradable while extremely effective, making it perfect for environmentally sensitive locations.

This water base product contains a grease cutter and ultra-pure surfactants that are natural and renewable with no compromise on performance. Meanwhile, the low-foaming characteristic reduces off-line wash cycle time, allowing you to be economical on water.

  • Versatile Like the other products in the FYREWASH® range, the F2 can be used for both on-line and off-line gas compressor cleaning.  F2 mixes readily with most antifreeze agents to allow low ambient temperatures on-line/off-line cleaning.
  • EffectiveF2 meets the stringent requirements of manufacturers around the world and targets a wide range of foulants. In most cases cleaning as well as a petroleum solvent while maintaining its water based characteristics.
  • Rewarding Light, regular cleaning with FYREWASH® F2 combined with occasional off-line cleans will help maintain an efficient, reliable and productive compressor.
  • Biodegradable The unique quality of this cleaner is its high biodegradability, making it ideal for gas turbines in marine environments.
  • Safe FYREWASH® F2 is used at thousands of sites. It is not only safe to use but helps keep your compressor running safely, too.
  • Insured We are extremely confident in our product, which is trusted around the world, and back it with our unique high value liability insurance.

  • EC Hazard rating: Xn, harmful. US NFPA rating 1,1,0
  • Protective equipment required: Wear suitable protective clothing including gloves and eye/face protection and use in a well ventilated area.
  • Spill management: Anyone cleaning up spilled FYREWASH® F2 should wear appropriate protective clothing and eye/face protection. Collect spilled fluid using a non-combustible absorbent material (i.e. vermiculite, sand or earth).
  • Fire: In case of fire, use foam, carbon dioxide, dry chemicals, sand or earth. Do NOT spray with water as this may spread the fire. The chemical may produce carbon monoxide when burning.

What injection system can it be used with?

F2 can be used with any on-line and off-line injection system.

How to use F2 for on-line gas turbine cleaning?

On-line gas turbine cleaning is normally performed by mixing one part FYREWASH® F2 concentrate with four (4) parts of water into a stable solution. The volume of chemical solution needed per wash and the optimum cleaning frequency will depend upon engine size, operating environment, and fouling tendency. It is recommended that a post rinse is performed to ensure that the nozzle system is cleaned and ready for next operation.

How to use F2 for Off-line gas turbine cleaning?

Concentrated FYREWASH® F2 is normally mixed with four (4) parts of good quality water. The solution is injected at cranking speed, allowed to soak for 20 to 30 minutes then thoroughly rinsed off at cranking speed with good quality water acceptable to the engine manufacturer. This compressor cleaning chemical can be used without dilution for offline cleaning, providing a superb cleaning result for heavily fouled compressors.
