HYDRINO Oil-Free Water-Injected Screw Compressor Launched by Kirloskar Pneumatic

The HYDRINO oil-free water-injected screw compressor marks a significant milestone in India’s industrial equipment landscape, as Kirloskar Pneumatic Company Limited introduced the new system in Bengaluru on 25 February 2026. Designed to meet stringent purity requirements, the HYDRINO oil-free water-injected screw compressor complies with ISO 8573 Class 0 standards, positioning it for critical sectors such as pharmaceuticals, food and beverage processing, and electronics manufacturing where contamination-free air is essential.

Commercial Launch and Institutional Collaboration

The HYDRINO oil-free water-injected screw compressor was commercially launched with support from the Foundation for Science Innovation and Development at the Indian Institute of Science. The initiative reflects collaboration between (Kirloskar) Pneumatic Company Limited and research-led innovation platforms aimed at strengthening domestic manufacturing capabilities in India.

Role of FSID and Pravriddhi Accelerator

Technical mentorship for the HYDRINO oil-free water-injected screw compressor was provided through Pravriddhi, a pan-India product accelerator operated by the Foundation for Science Innovation and Development. The program supports commercialization of indigenous technologies and aligns with national objectives focused on expanding India’s advanced manufacturing base.

Technology Architecture and Operating Principle

The HYDRINO oil-free water-injected screw compressor replaces conventional oil lubrication with water for cooling, sealing, and lubrication within the compression chamber and bearing system. This oil-free compressor technology ensures contaminant-free compressed air while maintaining operational stability in continuous industrial environments.

Performance and Efficiency Parameters

By integrating water-injected screw compressor architecture, the system achieves ISO 8573 Class 0 standards, the highest benchmark for oil-free air purity. The compact footprint, reduced noise levels, and optimized energy efficiency make the HYDRINO oil-free water-injected screw compressor suitable for modern industrial compressed air systems requiring reliability and low lifecycle costs.

Industry Applications and Market Relevance

Sectors such as pharmaceuticals, food processing, and electronics manufacturing demand industrial compressed air systems that eliminate contamination risks. The HYDRINO oil-free water-injected screw compressor addresses these requirements by delivering consistent, high-purity air compliant with ISO 8573 Class 0 standards, thereby supporting product integrity and regulatory compliance.

Indigenous Development and Strategic Impact

Developed indigenously by (Kirloskar) Pneumatic Company Limited with grant support from India’s Ministry of Heavy Industries, the HYDRINO oil-free water-injected screw compressor represents a shift in domestic capability. Oil-free compressor technology has historically been dominated by European and Japanese manufacturers, and local production reduces reliance on imported equipment.

With expanding demand for oil-free compressor technology across critical industries, the HYDRINO oil-free water-injected screw compressor strengthens India’s position in high-specification industrial compressed air systems while advancing manufacturing self-reliance.
