EnviroSenze 2500

EnviroSenze 2500 is an environment-tally friendly foam mimic concentrate with non-foaming properties. It is designed to be used when testing and commission foam systems. The foam mimic concentrate has been designed to have similar flow behaviour as traditional foam concentrate but has no foaming agents inside.
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 2500 is set be around 2500 mPas. This mimics an alcohol resistant foam concentrate in the lower viscosity range. The viscosity will not be exactly 2500 mPas, but rather around this value. The viscosity can vary from batch to batch between 1500 and 3000 mPas. 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 concentrate instead of 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.

Induction Ratio

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 2500 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 2500 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, at least 2 years 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.
We recommend following our guidelines for storage and handling ensuring favourable storage conditions.
