FOMTEC EnviroSenze 10
The foam mimic concentrate can also be used to determine induction ratio as measured by conductivity. The same foam mimic concentrate can be used for 1%, 3% and 6% systems. The lower detection limit is around 0,2% induction using ordinary tap water.
The viscosity of EnviroSenze 10 is set be around 10 mPas. This mimics a typical AFFF foam concentrate with low viscosity. The viscosity is approximate and can vary from batch to batch. Since viscosity also changes by temperature it is advisable to always measure the viscosity of the foam mimic solution before use.
Use the foam mimic solution instead of an ordinary foam concentrate to set-up and trim a foam system to the right induction ratio. The foam mimic solution is non-foaming and, hence, easy to handle after use. The foam mimic solution is fully biodegradable.
The foam mimic solution can be used for 1% to 6% systems to check induction ratio by conductivity.
|Appearance||Clear yellowish liquid|

|Viscosity at 20°C||≤ 10 mPas|

|Suspended sediment (v/v)||Less than 0,2%|
The foam mimic solution can be used to measure induction ratio over a wide range of mixing ratios. The figure below shows the conductivity and a calibration curve for 1%, 3% and 6% solutions in tap water.
Linear regression of the above curve gives a R-value of 0,9995 which is almost identical to a straight line for which the R-value is 1,000. If the linear regression gives a R-value below 0,9800 it is advisable to do new calibration solutions.
The lower mixing ratio limit in this case is about 0,2%. By using brackish or sea water the resolution will decrease. This has to be checked from case to case.
By measuring the conductivity of premix solution coming out from a system when released the induction ratio can be calculated by using the above calibration curve. The good R-value will give good precision in the measurement.

Disposal of premix solution
EnviroSenze 10 has been designed with ingredients suitable for discharge in sewers and drains as a premix from a system testing. The disposal in sewers and drains need to be checked with local authorities to obtain a permission for this before it is done. A special MSDS is available for a 6% premix solution of EnviroSenze 10 to present for authorities that represents a worst case scenario of the premix solution.
Storage / Shelf life
Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be dependent on storage temperatures and conditions. If the product is frozen during storage or transport, thawing will render the product completely usable.
Synthetic foam concentrates should only be stored in stainless steel or plastic containers. Since electrochemical corrosion can occur at joints between different metals when they are in contact with foam concentrate, only one type of metal should be used for pipelines, fittings, pumps, and tanks employed in the storage of foam concentrates. We recommend following our guidelines for storage and handling ensuring favourable storage conditions.
We supply this product in 25 litre cans and 200 litre drums. We can also ship in 1000 litre containers or in bulk.
