Puritas Energy

Green Technology Distributor

Puritas Energy is a green tech company which distributes fuel polishing technologies featuring DieselPure filters. Created specifically to address the unique chemical properties of ultra low sulphur diesel (ULSD) and biodiesel blends, the DieselPure coalescing filter has a two stage single pass design. Fuel is circulated through DieselPure filters on a predetermined schedule and filtered down to 0.2 microns. DieselPure filters have 100% efficiency at removing emulsified water in ULSD and 96% in biodiesel blends containing up to 20% biodiesel (as proven by the Society of Automotive Engineers SAE J1488:2010 Emulsified Water/Fuel Separation Test Procedure). Governments in North America and the European Union have mandated the use of ULSD and biodiesel blends (by region) to reduce the environmental burden of diesel. These mandates have a dramatic effect on critical power applications, such as data centers, relying on diesel backup generators for emergency supplies. The process of removing sulphur from diesel to create ULSD required additives to be included in fuel which did not meet the required standards once the sulphur was removed. Certain additives included in diesel increase the fuels ability to absorb both freestanding water (a layer of water at the bottom of a storage tank), and emulsified water (tiny micro-droplets suspended within the fuel) leading to microbial contamination and associated problems. Biodiesel blends containing 5%-20% biodiesel also absorb more water and form stronger bonds to it. Fuel polishing technologies distributed by Puritas were created in response to these specific changes in diesel.
