Tomoil Circulation Oils – A Reliable Lubrication Solution for High Industrial Performance

Tomoil Circulation Oils are specially formulated lubricants designed to ensure continuous, stable, and long-lasting performance of industrial equipment. These oils provide maximum protection under heavy load, variable temperature conditions, and extended operating cycles. Circulation oils are mainly used in:

  • generators and power production equipment

  • hydraulic units

  • compressors

  • turbines

  • pump and ventilation systems

The primary function of circulation oils is to reduce friction, minimize wear, prevent corrosion, and maintain a stable lubrication cycle. The oil flows continuously through the system, reaches all lubrication points via the pump, and returns to the main reservoir. Thanks to this uninterrupted circulation, equipment efficiency increases significantly.

Key Advantages of Tomoil Circulation Oils

1. Long-lasting and stable performance
Tomoil circulation oils are optimized for industrial systems that operate 24/7. Their high oxidation resistance helps maintain lubrication quality over long periods and extends service intervals.

2. High protection against corrosion and rust
Anti-corrosion inhibitors protect metal surfaces from oxidation and prevent rusting even when exposed to moisture.

3. High viscosity index

  • stable performance under varying temperature conditions

  • optimal fluidity in cold environments

  • no breakdown of the oil film at high temperatures

This is especially important for industrial systems operating under heavy load.

4. Water separation capability (demulsification)
Water contamination poses a serious risk in circulation systems. Tomoil formulations rapidly separate water from oil, which:

  • reduces friction

  • prevents metal adhesion, overheating, and rust

  • ensures oil stability

5. Low foaming and high stability
Thanks to anti-foam and anti-wear additive packages, Tomoil circulation oils minimize foaming and ensure safer and more efficient lubrication.

Application Areas

Tomoil Circulation Oils are suitable for a wide range of industrial sectors and are formulated for heavy-duty conditions:

  • Energy sector: steam and hydro turbines, high-speed rotary compressors

  • Industrial lines: high-precision control systems, bearings, fast mechanical components

  • General industrial use: fully compatible with Tomoil hydraulic oils, compressor oils, and other industrial lubricants

They perform effectively in both modern equipment and upgraded legacy systems.

Technical Specifications

Tomoil Circulation Oils are available in the following viscosity grades:

  • ISO VG 32

  • ISO VG 46

  • ISO VG 68

Key technical features:

  • high thermal and oxidation stability

  • consistent performance throughout the lubrication cycle

  • stability and long-term protection under heavy operating conditions

Selecting the right circulation oil extends equipment lifetime, reduces maintenance costs, and ensures uninterrupted production processes. Tomoil’s high-quality industrial lubricants meet all these requirements at the highest level.
