Specialty refrigeration oils manufacturer Extol has launched a new semi-synthetic lubricant, especially formulated for vac pumps. Using highly hydrocracked and isodewaxed oil and combined with an additive package, Extol VP is designed to withstand the toughest conditions encountered in recirculating systems with a range of features and benefits:
- Excellent oxidative stability – Longer system life
- Rust and Corrosion protection – Enhanced system reliability and reduced down-time
- Traction properties conserve energy – reduce internal fluid friction
Synthetic Oils Vs. Mineral Oils
Mineral Oil
Mineral oils are poorer quality and are merely a very basic conventional oil, which are not beneficial to the lubrication process. These have many impurities which cause poor flow in cold temperatures and produce by-products which reduce lubrication, efficiency, and wear resistance.
Synthetic Oil
Synthetic oil or semi-synthetic oils are highly refined, with many impurities removed through the process of chemical synthesis, ensuring they can circulate quicker. Semi Synthetic oils have been further refined, distilled, purified and broken down through a process of chemical engineering.
Why choose Synthetic
- Excellent viscosity/Temperature properties and shear stability for improved wear protection
- Low oxidation at high-temperatures and good thermal stability reduce deposit formation
- Good cold-temperature flow reduces energy consumption at low temperatures
- Significantly longer service life than the best mineral oils when stressed by temperature
- Low volatility reduces consumption
- Traction properties conserve energy reduce internal fluid friction
Features and Benefits:
- Excellent oxidative stability – Longer system life
- Rust and Corrosion protection – Enhanced system reliability and reduced down-time
- Demulsibility and excellent lubricity – increased efficiency and reduced cost of operation
- Low volatility – Reduced maintenance and top offs
