Engine Coolants and Adblue

Engine Coolant Analysis

ALcontrol’s engine coolant analysis programme allows you to monitor the condition of your cooling system, detect corrosion inhibition properties of the coolant and detect signs of corrosion or incorrect glycol (anti-freeze) levels. It may come as a surprise that although coolant is often referred to as anti-freeze its role in preventing the coolant freezing at low temperatures is only half the story. In fact, just as important role is the prevention of the coolant boiling when at high temperatures, in which boiling can cause pinhole sized bores through an engine liner and lead to a coolant leak. Therefore, it is  important to regularly check your coolant with ALcontrol to best protect your machinery. Our typical categories of customers include:                                                                                                             

Vehicle owners & Warranty (Automotive, construction, Marine etc) - Coolant analysis is often requested as part of a complete engine health check of engine oil, fuel, coolant and Ablue analysis and all are sampled routinely on warranty cases to ensure only valid warranty claims are paid out. It is not uncommon for Adblue and coolant to be mixed up by an operator filling the vehicle tanks, which can lead to a corroded coolant system and poisoned Catalyst brick; therefore, if any failure in these systems both the Adblue and coolant should be sampled.

 

Adblue/DEF Analysis

Adblue is an extremely pure 32.5% solution of urea in water and is injected into the exhaust system to remove Nitrogen oxide compounds such as NO and NO2 (commonly termed NOx ) which are a large contributor to acid rain. Many truck and agricultural engines are now fitted with NOX sensors to monitor emissions and require the Adblue system to deliver Adblue to remove these compounds.

A regular testing programme is necessary to monitor poor quality, as contaminated Adblue can poison catalytic converters. Leading to illegal emissions of NOX gases ALcontrol Laboratories test Adblue to the full ISO 22241-2 and DIN V70070 specifications related to Adblue/DEF. products Our typical categories of customers include: Suppliers – As a relatively new technology Adblue is very prone to contamination, which can damage catalysts. It is critical for all Adblue suppliers to have an independent laboratory continuously verify the quality of their product to build customer confidence and gain OEM approvals.

Vehicle owners & Warranty (Automotive, construction, Marine etc) – With recent updates in regulations agricultural and road haulage equipment now require Adblue on certain tiers of engine requests for Adblue analysis increase continuously. It is not uncommon for Adblue and coolant to be mixed up by an operator filling the vehicle tanks, which can lead to a corroded coolant system and poisoned Catalyst brick; therefore, if any failure in these systems both the Adblue and coolant should be sampled.
