• Wintron® additives are mixed with finished biodiesel. The biodiesel should be warm, and must be at least 5°C above the cloud point of the fuel i.e. it should appear clear

• Treat rate varies, and is largely dependent on the feedstock used to produce the biodiesel. Typically treat rate is 0.1% - 2% by volume (i.e. 0.5% would be equivalent to 5 litres of Wintron® additive made up to 1000 litres with biodiesel)

• Users must determine the required treat rate for their biodiesel

• Best results are seen with biodiesel produced from unsaturated oils such as Rapeseed oil, Canola oil, Sunflower oil, Soy oil etc. Results with used cooking oil are generally good. Wintron additives are least effective for biodiesel produced from highly saturated feedstocks such as Tallow and Palm oil.

• The Wintron® range of additives are viscosity modifying componds. These compounds achieve their effect by reducing the tendency of viscosity to increase as the fuel is cooled which alters cold temperature crystallisation. The freeze point (FP), pour point (PP) and cold filter plugging point (CFPP) are reduced.

The exact composition of biodiesel can vary, especially with biodiesel produced from used cooking oils. Users must determine the effectiveness and treat rate for their biodiesel.

When biodiesel is cooled below a certain point, some of the molecules aggregate and form crystals. The fuel starts to appear cloudy once the crystals become larger than one quarter of the wavelengths of visible light - this is the cloud point (CP) of the fuel.

As the fuel is cooled further these crystals become larger.

Wintron® additives affect cold temperature crystallisation and reduce the temperature at which these crystals become large enough to block the pores of a fuel filter (CFPP - cold filter plugging point)

The CFPP and CP can be further lowered by cold filtration of the fuel.

Longer chain saturated biodiesel molecules tend to crystallise first. Although these molecules generally have higher cetane values, the overall cetane value of cold filtered fuel will generally fall well within accepted standards.

Cold filtration will reduce the cloud point of biodiesel and reduce the CFPP and PP of biodiesel to lower temperatures that can be achieved using additives alone

To make ultra cold weather biodiesel it is best to produce the biodiesel from an oil that already has good cold flow characteristics such as Rapeseed oil

• Mix warm biodiesel with Wintron® additive(s) that maximally reduce pour point of biodiesel.

• Allow to cool to below the cloud point - the fuel must still be able to flow

• Filter the biodiesel to 1 micron

CFPP - cold filter plugging point: lowest temperature at which a sample can pass through a filter. Conditions specified by EN116, ASTM D 6371 & IP 309 – the lowest temperature at which a 20ml sample passes through a 45μm wire mesh under 0.0194atm vacuum within 60s
