Efficient Oil Cooling for Gearbox in the Cement Industry. How a High-Performance Plate Heat Exchanger Ensured Thermal Stability and Operational Continuity.

Contributed by: Narendra Joshi and Sourabh Mishra

Application: Gearbox Oil Cooling
Objective: To maintain optimal oil temperature in high-viscosity lubrication systems for gearboxes in cement plants, ensuring uninterrupted operations and minimizing production losses due
to overheating.
Challenge: A prominent cement manufacturing company’s conventional cooling systems were failing to maintain the oil temperature within the optimal range, jeopardizing equipment performance and leading to avoidable downtime.

Background with the Existing System
In heavy-duty industrial applications, particularly in the cement industry, gearboxes are critical components that must operate under high mechanical loads and harsh conditions. These gearboxes rely on lubrication systems where oil plays a dual role, lubrication and heat dissipation. A recurring challenge in such setups is managing the temperature of the gearbox oil. When oil heats beyond a critical limit, its viscosity drops, reducing its ability to form a protective film. This leads to increased friction between components, heat generation, and eventual damage to gearbox components — directly impacting plant uptime and production output.

Delivering Sustainable Heat Transfer Solution with HRS FUNKE High Efficiency Heat Exchanger
This system was selected for its:

  • Excellent thermal performance, ensuring rapid and efficient oil cooling even with high-viscosity fluids.
  • Leakage-proof operation, with no cross-contamination between cooling water and lubrication oil.
  • Robust design, capable of withstanding high operating pressures and variable flow conditions.

The plate exchanger was custom configured based on the oil’s properties, desired outlet temperature, and ambient heat load, ensuring that the oil remained within the specified viscosity range necessary for maintaining gearbox operation and lubrication integrity.

Performance Benefits Delivered

  • Oil temperature control and maintained consistently within target range
  • Viscosity stability and prevented breakdown of lubrication film
  • Equipment reliability and reduced risk of gearbox overheating or failure
  • Production continuity and eliminated unplanned stoppages
  • Long-Term savings and lower maintenance costs and extended oil life

Solution: To address the problem, HRS Process Systems Ltd recommended the installation of a Funke Plate Heat Exchanger a compact, high-efficiency thermal solution engineered specifically for industrial lubrication oil cooling.

Conclusion: The customer achieved precision oil temperature control, ensuring that the gearboxes operated at optimal conditions. This not only safeguarded the mechanical integrity of the gearbox but also directly contributed to higher plant uptime and improved production efficiency in heavy industries like cement manufacturing.

Nuvoco Vistas Corp. Ltd., one of India’s leading building materials companies, has reported its highest-ever second-quarter consolidated EBITDA of Rs 3.71 billion for Q2 FY26, reflecting an 8% year-on-year revenue growth to Rs 24.58 billion. Cement sales volume stood at 4.3 MMT during the quarter, driven by robust demand and a rising share of premium products, which reached an all-time high of 44%.

The company continued its deleveraging journey, reducing like-to-like net debt by Rs 10.09 billion year-on-year to Rs 34.92 billion. Commenting on the performance, Jayakumar Krishnaswamy, Managing Director, said, “Despite macro headwinds, disciplined execution and focus on premiumisation helped us achieve record performance. We remain confident in our structural growth trajectory.”

Nuvoco’s capacity expansion plans remain on track, with refurbishment of the Vadraj Cement facility progressing towards operationalisation by Q3 FY27. In addition, the company’s 4 MTPA phased expansion in eastern India, expected between December 2025 and March 2027, will raise its total cement capacity to 35 MTPA by FY27.

Reinforcing its sustainability credentials, Nuvoco continues to lead the sector with one of the lowest carbon emission intensities at 453.8 kg CO? per tonne of cementitious material.

Jindal Stainless Limited has announced an investment of $150 million to build and operate a new wet milling plant in Jajpur, Odisha, aimed at doubling its capacity to recover metal from industrial waste. The project is being developed in partnership with Harsco Environmental under a 15-year agreement.

The facility will enable the recovery of valuable metals from slag and other waste materials, significantly improving resource efficiency and reducing environmental impact. The initiative aligns with Jindal Stainless’s sustainability roadmap, which focuses on circular economy practices and low-carbon operations.

In financial year 2025, the company reduced its carbon footprint by about 14 per cent through key decarbonisation initiatives, including commissioning India’s first green hydrogen plant for stainless steel production and setting up the country’s largest captive solar energy plant within a single industrial campus in Odisha.

Shares of Jindal Stainless rose 1.8 per cent to Rs 789.4 per share following the announcement, extending a 5 per cent gain over the past month.

Vedanta Limited has received approval from the Competition Commission of India (CCI) to acquire Jaiprakash Associates Limited (JAL) for approximately Rs 17,000 million under the Insolvency and Bankruptcy Code (IBC) process. The move marks Vedanta’s strategic expansion beyond its core mining and metals portfolio into cement, real estate, and infrastructure sectors.

Once the flagship of the Jaypee Group, JAL has faced severe financial distress with creditors’ claims exceeding Rs 59,000 million. Vedanta emerged as the preferred bidder in a competitive auction, outbidding the Adani Group with an overall offer of Rs 17,000 million, equivalent to Rs 12,505 million in net present value terms. The payment structure involves an upfront settlement of around Rs 3,800 million, followed by annual instalments of Rs 2,500–3,000 million over five years.

The National Asset Reconstruction Company Limited (NARCL), which acquired the group’s stressed loans from a State Bank of India-led consortium, now leads the creditor committee. Lenders are expected to take a haircut of around 71 per cent based on Vedanta’s offer. Despite approvals for other bidders, Vedanta’s proposal stood out as the most viable resolution plan, paving the way for the company’s diversification into new business verticals.
