EnviroSenze 800 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.

Features

  • Proportioning test liquid
  • Non-foaming
  • Environmentally friendly – 100% biodegradable
  • Measure induction ratio

Description

The proportioning test liquid can be used to determine induction ratio by conductivity measurements. The same proportioning test liquid 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 800 is set be around 800 mPas. This mimics a typical pseudoplastic foam concentrate with viscosity around 800 mPas. 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 proportioning test liquid before use.

Application

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.

Typical data

  • Appearance – Clear yellowish liquid
  • Specific gravity at 20°C – 1,04 +/- 0,01 g/ml
  • Viscosity at 20°C – ≤ 800 mPas
  • pH – 6,5 – 8,5
  • Freezing point – -0°C
  • Recommended storage temperature – -0 – 55°C
  • Suspended sediment (v/v) – Less than 0,2%

Induction ratio

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 an 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 an 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.

Disposal of premix solution

EnviroSenze 800 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 800 to present for authorities that represents a worst-case scenario of the premix solution. For more detailed information please consult Fomtec Technical Advices FTA 40.

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 Fomtec Technical Advices FTA 10 for storage and handling ensuring favourable storage conditions.

Packaging

Fomtec supplies this product in 25 litre cans and 200 litre drums. We can also ship in 1000 litre containers or in bulk.
