History and development

The journey of Refex Industries began in 2002 as Refex Refrigerants Pvt. Ltd., focused on manufacturing and refilling eco-friendly refrigerant gases. Over the years, the company has established itself as a leading player in India's cooling solutions market, especially with eco-friendly alternatives to harmful chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). 

By 2006, the company converted into a public limited company, later listed on the Bombay Stock Exchange (BSE), and expanded its product line to meet the demands of the national industry. In 2012, the company was renamed Refex Industries Ltd., reflecting a broader industrial focus beyond refrigerants. 

Over time, Refex diversified into several strategic sectors such as ash and coal management, power trading, renewable energy (including solar and wind), and green mobility, and built a portfolio tailored to India's industrial and environmental priorities. 

Main Business Segment

1. Refrigerant gases

One of the fundamental business units of Refex is the production and distribution of environmentally friendly refrigerant gases used in HVAC (heating, ventilation and air conditioning) systems, industrial refrigeration, aerosol propellants.and foaming agents. These refrigerants are designed to replace older, ozone-depleting chemicals – in line with global environmental protocols on refrigerants. 

Refex's refrigerant offerings include a wide range of products such as R32, R134A, R404A, R407C and others, all manufactured with strict quality control and distributed through an extensive logistics network to ensure timely service. 

2. Ash and coal management

It has become one of the largest organized players in coal and ash management services in India. The company provides integrated solutions for thermal power plants, including sourcing, logistics, storage, handling and disposal of coal and fly ash – a by-product of coal combustion. 

Ash management is particularly important in India, where strict environmental regulations require power plants to dispose of ash responsibly and minimize ecological impact. Refex not only manages the ash, but also seeks sustainable repurposing solutions that support infrastructure development such as road construction and land reclamation. 

With thousands of metric tonnes of ash and coal being handled per day across multiple states, this segment has grown rapidly.

3. Power Trading

Through this segment, the company deals with both conventional and renewable energy sources, offering solutions for power exchange, bilateral contracts and banking arrangements between power producers, distribution companies and various energy consumers. 

Power trading enhances grid efficiency and allows stakeholders to balance surplus and deficit power, a key requirement in India's rapidly evolving energy infrastructure.

4. Renewable energy and green mobility

Challenges and recent developments

In late 2025, the company and its associated entities were subject to tax investigation by the Indian Income Tax Department, alleging significant tax evasion and suspicious financial transactions involving fraudulent purchases and unexplained investments. Refex said it would cooperate with authorities during the investigation process. 

Such developments highlight the importance of strong corporate governance and transparent financial practices, especially for growing conglomerates operating across different sectors.
