Bhavani Industries India LLP
Product Supplied
5.5 kW Industrial Oil Chiller
Application
Oil cooling for ISO VG 68 hydraulic oil used in hydraulic systems and gear grinding machines
Background
Bhavani Industries India LLP operates precision hydraulic and gear grinding machines where oil temperature stability is critical. During continuous operation, hydraulic oil temperature tends to rise due to friction, load variations, and ambient conditions. This temperature rise directly affects oil viscosity, machine accuracy, seal life, and overall system reliability.
To overcome these challenges, Bhavani Industries required a reliable and compact oil chiller capable of maintaining oil temperature within the recommended range for ISO VG 68 oil.
Challenges
-
Rise in hydraulic oil temperature during continuous machine operation
-
Variation in oil viscosity affecting holding force and machining accuracy
-
Premature wear of hydraulic components and seals
-
Increased maintenance frequency and downtime
Solution Provided
Himalaya Refrigeration Industries supplied a 5.5 kW oil chiller, specifically designed for hydraulic oil cooling applications. The system was engineered to maintain oil temperature as per the ISO VG viscosity–temperature chart, ensuring consistent oil performance under varying operating conditions.
The chiller was integrated seamlessly with the existing hydraulic and gear grinding setup, ensuring stable cooling without disrupting production.
Key Benefits Achieved
-
Constant Oil Temperature Control
Maintains ISO VG 68 oil within the ideal temperature range, ensuring stable viscosity as per ISO VG temperature charts. -
Improved Hydraulic Performance
Consistent oil viscosity helps maintain constant hydraulic holding force, improving machining precision and repeatability. -
Extended Seal & Component Life
Controlled temperature reduces thermal stress on hydraulic seals, hoses, and valves, resulting in longer service life. -
Reduced Wear & Tear
Proper lubrication characteristics minimize internal friction, reducing wear on pumps, valves, and moving parts. -
Lower Maintenance & Downtime
Reduced component failure and oil degradation lead to lower maintenance costs and improved machine availability.
Conclusion
By installing the 5.5 kW oil chiller, Bhavani Industries India LLP achieved stable hydraulic oil temperature control, enhanced machine performance, and reduced long-term maintenance requirements. The solution ensures reliable operation of hydraulic and gear grinding machines, supporting consistent product quality and improved operational efficiency.
