We take great pleasure in having manufacturing capabilities that are state of the art as well as an amazing workforce that is capable of continuously delivering outstanding results. In Bhiwadi, Neemrana, and Chennai, we have three prominent manufacturing sites that are dedicated solely to the production of HVAC and refrigeration components.
This is one of the largest factories for manufacturing of heat exchangers in the country. This plant was previously owned and operated by Lloyd Group and manufactures evaporator and condenser coils for air conditioners and HVAC applications using the most cutting-edge equipment from world-class companies like Burr Oak of the USA and Hidaka of Japan.
Our Bhiwadi plant is uniquely positioned in the mobile HVAC systems space as well as in the heat transfer industry due to its extended capability to design, develop, manufacture, and maintain highly engineered HVAC systems for the railway, metro and bus coach industry. This capability extends to our ability to design, develop, manufacture, and maintain these systems as well.
In addition to being the top Heat Exchanger manufacturer in India, this Bhiwadi facility has a long history of manufacturing HVAC systems and related components for:
- Indian Railways – Level 1 supplier
- Metro Trains
- Defense HVAC for rigorous usage
- Bus air-conditioning
- Refrigerated Vehicles
- Data Centres, Commercial Air-conditioning & Refrigeration
This unit was established in 2021 and is outfitted in accordance with the standards of the Japanese market. It possesses a youthful and energetic workforce that is responsible for the production of complex copper tube assemblies that are subjected to the most modern testing and leak detection.
Having a long association with Korean MNCs and other domestic players, the Chennai setup caters to air con and refrigerator tube components. The southern region of India is home to a large number of enterprises that specialise in air conditioning and refrigerators; as a result, the setup in Chennai is excellent and well-prepared to meet the needs of a wide variety of customers.

High Standards of Quality Testing
Heat exchanger manufacturing requires meticulous attention to every last detail across stages. Our condenser and cooling coils meet the stringent technical specifications and quality standards set by its HVAC&R clients globally from HVAC&R industry.The coils undergo rigorous leak testing. The coils are protected from moisture intrusion during storage and transportation by being dehydrated by hot, dry air and having their pressure adjusted by dry nitrogen. Modern coil design software and a cutting-edge facility for testing coils and AC systems up to 15 tonnes assure high-quality products that are ideal for their application regions.
Our state-of-the-art testing facilities include:
- Modern Helium Leak Testing Setup
- A facility for auto brazing
- Completely in-house U BEND production facility
- Inhouse copper and header shop.
- Sheet metal workshop that uses an Amada CNC turret
- The Psychometric Lab of 18 Tons, one of the biggest HVAC testing facilities in India
- Complex leak detection systems, including nitrogen flushing, manual and automatic dip tank processes, high-pressure testing, and dehydration ovens
Raw Materials And Processes
Quality is not just a corporate or management jargon, it is a way of life for us. From the acquisition of raw materials to the production processes, from R & D to post-sales support services, there is a strong emphasis on quality.
