EnviroSenze 2500 is an environmentally friendly proportioning test liquid with non-foaming properties. It is designed to be used when testing and commissioning foam systems. The proportioning test liquid has been designed to have similar flow behavior as traditional foam concentrate but has no foaming agents inside.
Use the proportioning test liquid instead of an ordinary foam concentrate to set-up and trim a foam system to the right induction ratio. The proportioning test liquid is non-foaming and, hence, easy to handle after use. The proportioning test liquid is fully biodegradable.
The proportioning test liquid can be used for 1% to 6% systems to check induction ratio by conductivity.
| Appearance | Clear yellowish liquid |
| Specific gravity at 20°C | 1,04 +/- 0,01 g/ml |
| Viscosity at 20°C | ≤ 2500 mPas |
| pH | 6,5 – 8,5 |
| Freezing point | -0°C |
| Recommended storage temperature | -0 - 55°C |
| Suspended sediment (v/v) | Less than 0,2% |
The proportioning test liquid 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 must 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.
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 Fomtec Technical Advices FTA 10 for storage and handling ensuring favourable storage conditions.
