Frost-resistant diesel exhaust fluid (DEF) Defrosta – production has started

In the spring, we announced that we are developing a new type of solution for the market that improves operational reliability and provides an alternative method for reducing nitrogen oxide (NOx) emissions in SCR diesel vehicles, especially in cold conditions.

Defrosta is designed for use in urea-based selective catalytic reduction (SCR) systems by improving their frost resistance and operational reliability. Defrosta ensures efficient SCR system performance down to approximately -30 °C.

The product is intended for professional use only and will be tested in different vehicles and conditions during this winter season. Through testing, we aim to ensure the product’s functionality in the SCR systems of various types of vehicles.

If the SCR system includes a quality sensor that measures the properties of the product, its compatibility with Defrosta must be verified. A quality sensor malfunction may prevent the vehicle/machine from being operated. The sensors of the SCR system can be checked, for example, at the nearest service shop.

Defrosta is available through our commercial partner Arom-dekor Kemi Oy. Available only in 1000 litres IBC-containers.
