Mono and Multi layer Coolant/SCR tubing is manufactured to DIN 73378 tolerances

Valpar manufacture a range of mono layer (HIHL) and multi layer tubing (PVDF) for use as standard coolant lines, details of which can be provided on request.

In response to customer and regulatory driven demand which has spurred a move towards restricting road vehicle emissions, Valpar have on offer a range of SCR lines.

Selective catalytic reduction is a process involving a catalyst for the means of converting nitrogen oxides (NOx) into natural components found in the air we breathe. These systems use a reducing agent in order to set off this chemical reaction which is most commonly automotive grade Urea, also known as Diesel Exhaust Fluid (DEF) / AdBlue.

SCR is one of the most cost and fuel effective methods currently available that help reduce diesel engine emissions. Systems which use a SCR will have an onboard tank containing the reducing agent which are subject to replenishment. The reducing agent is a critical factor in the SCR system and must be present in the tank at all times in order to ensure the continued operation of the vehicle equipment.

Working closely with our customers and raw material suppliers, Valpar have produced SCR coolant lines designed to meet the specifications necessary to deliver DEF/ AdBlue around the SCR system. These lines are available in multi layer polypropylene and sizes are available on request.
