Oil is a critical component in screw compressors. Its condition is the key element in determining the service life of the machine, and by the nature of operation, it is constantly exposed to contamination.
The Berusynth range of synthetic oils with performance additives provide long service life for screw compressors. The PAO based oil with excellent thermal stability and ageing resistance extend draining intervals to 8,000 to 10,000 working hours. The special formulation does not impact paints or seals of the equipment while superior anti-wear and anti corrosion additives enhance equipment life. Berusynth H1 series also extends life of air-oil separator depending on operating conditions of the equipment.
Berusynth 46 H1 and Berusynth 68 H1, that is viscosity grades of 46 cSt & 68 cSt are suitable for Screw compressors. Berusynth H1 range is recommended for compressors in various industrial sectors including Cement, Power, Steel, Textiles, Mining and many more. Berusynth H1 range is NSF H1 approved and is recommended for compressor applications in Food, beverage and Pharma processing industries as well.
NSF H1 approved, high performance synthetic oils with high load carrying ability. Berusynth H1 series provide superior corrosion protection and offer wear resistance to the contacting surfaces. Halal and Kosher approved, Berusynth H1 are available in varying viscosities for industrial requirements.
Applications: Ready to meet the lubrication requirements of air and screw compressors, circulation systems and hydraulics, fans and pumps etc. Suitable for requirements of food, pharma and feed industry.

Frequently Asked Questions
Short bytes for queries on lubricants that always bothered you
Emulsifiers help in increasing solubility of the cutting oil in water by breaking down the oil into smaller globules and thereby maintaining a stable and uniform emulsion. A stable emulsion provides longer tank life and also ensures lower carry over loss resulting in minimum top ups.
The basic function of a cutting fluid is to provide adequate lubrication to the tool and work piece friction zone as well as remove heat generated by cooling the deformation area. Some additional properties that are desired in the cutting fluid are,
- Ability to rinse away the metal debris from the friction zone
- Provide adequate protection against corrosion to the machine and work piece
- Compatible to machine paint and ensure stain free machines
- Easy to handle and comply to safety and environmental regulations
Intense amount of heat is generated between the grinding wheel and work piece due to friction and cutting process. Uncontrolled heat can lead to structural damage of the work piece and increase in wear rate of the wheel. Fine dust and metal debris are continuously generated and needs to be cleared out from the wheel, work piece interface. The cutting fluid for Grinding process should possess the right amount of lubricity and cooling property to reduce friction and manage temperature rise. Additionally the cutting fluid should also possess the right amount of detergency and flushing property to clear the fine machined debris.
With a higher dosage of lubricity to reduce friction and temperature rise, the coolant should also contain EP additives that can protect the tool by forming a thin layer between the tool and work piece. Additionally, the cutting fluid should possess the right amount of flushing property to clear the machined swarf from the machined area
Ideally, de mineralized (DM) water with neutral pH of 7 and hardness less than 50 ppm is recommended. The chloride level should be less than 25 ppm with no bacterial and fungal presence. Usage of hard water leads to increased conductivity, hence poor rust protection and lower sump life.
‘Oil into water’ or ‘oil in last (OIL)’ is a recommended practice for better solubility of the coolant in water. Water in oil would result in large size oil globules with the oil loving ‘oleopphilic’ ions of the emulsifier being ineffective. This would lead to a unstable oil water emulsion.
- Keep a regular check on the concentration of the emulsion, maintain recommended concentration
- Remove any tramp oil from the coolant tank thoroughly
- Measure pH regularly
- Avoid all sorts of dust near the tank, remove the machined debris from the tank regularly.
- Follow the prescribed procedure while changing the coolant.
Including the effectiveness of ‘cutting fluid’, tool life is impacted by a host of other parameters including cutting speed, feed rate, depth of cut, tool and work material, nature of cut and machine rigidity. Cutting fluids with high amount of EP additives would insulate the tool from frictional wear and ensure longer life. Studies have shown that with all other parameters remaining the same, cutting fluids with good EP properties can increase tool life by 20 to 40%.
Aluminum alloys which contain Copper and Zinc as alloying elements are susceptible to chemical reaction (black stains) with cutting fluids that contain Amines as ingredient. For machining such Aluminum alloys, amine free cutting fluids are recommended
Colour change of the emulsion is notable during machining of Cast Iron with the Fe ions dissolving with the emulsion. However with all other parameters such as pH, conductivity, concentration and microbial behavior remaining within the specified limits, colour change does not impact performance of the emulsion.
Operators handling components with bare hands and in constant touch with the emulsion could feel irritation and itchiness or develop rashes as well. As sensitivity of the skin is subjective, operators need to handle machined components with proper gloves and other protective gear with the objective of avoiding direct contact with the emulsion. Barrier creams could also be considered where direct contact is unavoidable.
Ensuring a stable emulsion with regular check on pH levels and microbial growth by removing chips, swarf and tramp oil from the tank will also help in reducing possibilities of such concerns. Encourage operators to maintain good personal hygiene, recommend regular laundry of their work dress, avoiding wet rags into pockets, usage of mild soaps etc.
