Total Lubmarine’s new coolant reduces operating costs and pollution

05 Feb 2020

Total Lubmarine on Tuesday (4 February) launched its WT SUPRA Coolant – a coolant that claims to be an environmentally friendly inhibitor concentrate that delivers extended service life and corrosion protection using its patented carboxylate technology. 

“We offer a solution to help increase operating performance and protection for both engine manufacturers and operators alike, and which gives complete assurance on their engine performance,” says Stuart Fuller, Global Brand Manager at Total Lubmarine.

Formulated using organic technologies, the product has been specifically designed for use in marine 2 stroke, 4 stroke and stationary engines as well as smaller, high speed auxiliary engines. 

“WT SUPRA, contains none of the inorganic ingredients, such as phosphates, nitrates, amines, boron or silicates, typically found in other coolants,” says Fuller. “We have been careful to develop an advanced solution that reduces the need for frequent waste disposal and provides added protection to the environment with non-polluting properties. It uses the latest organic technology, delivering high performance and extended service life to equipment, reducing overall maintenance costs.”

The science behind WT SUPRA provides:

  1. enhanced protection of wet cylinder liners at increased temperatures
  2. exceptionally low inhibitor depletion rate ensuring long term system protection
  3. excellent protection of engine materials against corrosion and cavitation, including aluminum, brass, copper, solder, steel, and cast iron
  4. outstanding service life – at least 32,000 hours in engines with just a 5 vol.% concentration.

“With WT SUPRA there’s no need to introduce supplementary additives when using WT SUPRA because there is minimal depletion of the coolant’s active ingredients,” says Fuller. “It is in essence a ‘fill-for-life’ product, which saves on regular maintenance and costly downtime especially when correct top-up procedures are followed.”

“As part of this analysis we carry out aging tests that are conducted under more severe conditions compared to those commonly used in the industry. Results have shown that the organic inhibitors used in WT SUPRA provide optimal results even at high running temperatures due to its strong anti-corrosion and anti-cavitation protectors.”
