Minimac Systems Raises Rs 30 Crore Pre-Series A to Scale Industrial Lubricant Circularity

Minimac Systems, an industrial deep-tech company focused on lubricant lifecycle management and industrial circularity, has raised Rs 30 crore in a pre-Series A funding round led by Rainmatter, the investment firm backed by Zerodha. The round also saw participation from other venture capital investors.

The fresh capital will help Minimac accelerate research and development across miniaturised treatment infrastructure, fleet automation and fluid analytics. The company also plans to expand its Recycling on Wheels model through regional hubs located across major industrial clusters in India.

Minimac Systems Raises Rs 30 Crore

Founded in 2012 by Anshuman Agrawal, Minimac Systems develops technologies designed to improve industrial reliability while extending the useful life of lubricants.

The company is working to move industrial lubricant management beyond simply purchasing and replacing fluids. Its approach focuses on monitoring lubricant health, restoring fluids that can still be used and recovering materials from lubricant that has reached the end of its useful life.

The new funding will also support Minimac's commercial, digital and operational expansion as it develops its Lubricants as a Service offering.

Tackling India's Lubricant Consumption

India is currently the world's third-largest lubricant market, consuming more than 5 million tonnes of lubricants and greases annually.

Minimac is building its business around reducing the need for fresh lubricant consumption by keeping existing industrial fluids in productive use for longer. The company says this approach can support both industrial efficiency and resource conservation.

Its technology platform is structured around three stages - NanoCircularity, MicroCircularity and MacroCircularity.

Three Layers of Lubricant Circularity

NanoCircularity focuses on monitoring lubricants while they are being used inside industrial machinery. The system combines condition monitoring, contamination control and fluid-health analytics to assess lubricant performance and identify potential issues.

MicroCircularity focuses on restoring recoverable lubricant directly at industrial facilities. Minimac's treatment systems remove contaminants, moisture and degradation by-products, allowing the lubricant to be returned to service.

MacroCircularity addresses lubricant that can no longer be restored. Such fluids can be sent to registered re-refiners for conversion into re-refined base oil, or RRBO.

Together, these stages are designed to cover the lubricant lifecycle from active use and monitoring through restoration and eventual recovery.

Scaling Recycling on Wheels

One of Minimac's key initiatives is Recycling on Wheels, a mobile lubricant treatment model designed to bring processing capabilities directly to industrial sites.

The company's miniaturised systems can process approximately 10 to 4,000 litres of lubricant per minute, depending on the system configuration. Instead of transporting large volumes of used lubricant away from a facility, the technology enables assessment and treatment at the industrial site.

Minimac plans to establish regional hubs across major industrial clusters to scale the Recycling on Wheels model.

The company aims to abate 860 gigagrams of CO2e emissions by 2034 through its lubricant circularity approach.

From Equipment Sales to Lubricants as a Service

Minimac is also developing a broader business model in which it manages lubricant performance throughout an industrial asset's lifecycle.

The proposed model can cover lubricant supply, monitoring, restoration, compliance and end-of-life recovery. Rather than relying exclusively on equipment sales, the company plans to structure contracts around outcomes such as equipment uptime and fluid health.

This shift could allow industrial customers to treat lubricant management as an operational service rather than simply another maintenance expense.

2,500+ Systems Deployed

Minimac Systems claims to have deployed more than 2,500 miniaturised fluid-treatment systems with combined installed processing capacity exceeding 300,000 litres per minute.

The company says its technology has been deployed across more than 2,200 industrial assets and has helped keep over 14 million litres of lubricant in productive use across India and international markets.

Its customer base includes large industrial organisations such as NTPC, Adani Power, JSW Steel and Tata Steel.

A Growing Industrial Circularity Opportunity

Lubricant circularity remains a relatively niche segment in India, but interest in used-oil recycling and resource recovery is increasing.

Companies including Santosh Petrochemical Innovations and ReVivo's LubeLoop are working on used-oil re-refining and resource recovery technologies. Meanwhile, partnerships between major energy companies and industrial players are also emerging around nationwide used-oil collection and recycling.

Rainmatter has also invested in adjacent circularity technologies, including chemical recycling startup PolyCycl.

For Minimac Systems, the latest Rs 30 crore funding round marks an opportunity to move beyond individual fluid-treatment systems toward a broader industrial lubricant lifecycle platform.

With investment going into technology development, Recycling on Wheels, regional infrastructure and commercial capabilities, the company is now looking to scale its circularity model across India's industrial ecosystem and international markets.
