Enexio

What Enexio does

Enexio designs, manufactures and services air-cooled condensers (ACC), natural draft and induced draft cooling towers and hybrid cooling systems for power generation utilities and large industrial facilities. Its product portfolio rests on patented physical technologies: the ALEX Fin Tube Bundle (a self-supporting single-row finned steel tube with continuous aluminum cladding, metallurgically bonded via precision brazing, eliminating A-frame steelwork), the InAIR induced draft ACC (delivering up to 60% steel-structure reduction and 10-25% construction cost savings), Heller-Technology dry cooling inherited from 1940, the MinWaterCSP Hybrid Cooling Deluge ACC (cutting water consumption up to 95%), and the Circumix waste-management system. The firm conducts in-house manufacturing of tube bundles, fills, drift eliminators and nozzles across two ISO-certified facilities in Chennai, India, alongside a project reference base exceeding 1,000 installations across India, South Africa, Iraq, Morocco, Oman, the USA, Italy, Australia and Germany.

The company's business model combines large-ticket, project-based equipment sales (Classic ACC, InAIR, natural draft and induced draft cooling towers, plus cooling tower components) with a recurring after-sales service franchise covering maintenance, tube bundle replacement, spare parts, vibration measurement and performance optimization for any make of cooling equipment. It sells through direct enterprise field sales via regional offices in Chennai (headquarters), Mumbai and New Delhi, targeting state electricity boards (RRVUNL, TANGEDCO), central utilities (NTPC, NPCIL), private power producers, and EPC contractors with technical consultation through toll-free and direct sales lines.

Enexio traces its technology lineage to GEA Group AG (1920) and the 1935 invention of the Air Cooled Condenser; following Triton funds' 2014 acquisition of GEA's Heat Exchangers Segment, the Power Cooling Solutions division was spun off as the standalone ENEXIO brand in 2015. In May 2023, Chennai-based EPC group BGR acquired ENEXIO's global ACC business including the IP portfolio and manufacturing facilities, consolidating worldwide dry-cooling operations under Indian ownership. Governance is led by Swarnamugi Raghupathy as Chairperson and Managing Director.

Products and services

• Classic Air Cooled Condenser (ACC) Direct dry cooling system wherein steam is condensed inside fin tubes with aluminum-plated single-row condensing tubes brazed with aluminum fins, providing air-cooled steam condensation without requiring water for main cooling of power plants. Used for thermal, nuclear, and concentrated solar power plants worldwide.
• InAIR (Induced Draft Air Cooled Condenser) Next-generation air cooled condenser featuring induced draft fans with self-supporting ALEX bundles, offering reduced height, smaller footprint, and up to 60% reduction in steel structure quantities compared to classic forced draft ACC. Targets power plants needing compact dry cooling with reduced construction duration.
• ALEX-SYSTEM (Aluminum Finned Steel Tube System) Patented self-supporting finned tube bundle consisting of one-side aluminum clad carbon steel tube with aluminum finnings hard-soldered between flat ducts, requiring no A-supports and enabling quick ground-level preassembly. Used as core heat exchanger component inside ACC systems.
• Hybrid Cooling Deluge ACC Integrated hybrid cooling system combining traditional dry air cooled condenser fan cells with a small number of wet cells where steam is condensed inside tube bundles through external deluge cooling, part of the EU-funded MinWaterCSP program reducing water consumption by up to 95%. Targeted at arid region power plants needing limited supplementary wet cooling.
• Natural Draft Cooling Tower Large natural draft cooling tower with almost complete lack of moving parts for high operating reliability and minimal maintenance, featuring 2H cooling fills and thermal design based on in-house software. Includes the world's second-tallest (202m) Natural Draft Cooling Tower delivered for RRVUNL Kalisindh.
• Induced Draft Cooling Tower Engineered induced draft cooling tower with counter-flow designs and modular cell configurations for flexible, scalable operation across industrial, chemical, and power plant applications. Includes trickle and splash fill configurations manufactured in Chennai facility.
• ALEX Tube Bundle (ATBF) Single-row, flat-shaped steel tube with continuous aluminum cladding and finned aluminum elements metallurgically bonded via precision brazing, self-supporting without A-Frame steelwork. Produced in-house at Enexio's ISO-certified Chennai manufacturing facility for use in ACC installations and aftermarket replacements.
• Cooling Tower Components (Fills, Drift Eliminators, Nozzles) High-performance trickle grid fills, splash fills, drift eliminators, and nozzles manufactured in the Chennai facility with UV-stabilized, fire retardant, chemical-resistant polymers for extended service intervals. Used in wet cooling tower retrofits and new builds, including Modular NF-20 Splash Fills for NPCIL Kakrapar nuclear power plant.
