Subros Auto Air conditioning Systems, manufacturer of thermal products for automotive applications claims that it is the only integrated manufacturing unit in India for auto air conditioning systems whose products could be designed, evaluated and tested on all grounds indigenously. This positions them unique amongst fellow combatants. Subros in collaboration with Japan based Denso corporation, a global leader in thermal products, manufactures air conditioning systems for auto vehicles inputting the machines with latest technological gadgets.

Speaking to Auto Components India, on the innovation and technology revamping in the air conditioning system Pawan Sabharwal, Director, Marketing said that, “Technical adherence is mandate on each component as we do not have all the components lose its market value in one shot. We have now compressors sitting in the hood occupies less space. As a company we are now working on 2 principles like reducing the size of the machine and reducing the weight of the machine by means of which we would be able to place ourselves in the league of light weighting initiators in auto segment. In addition to compressors, we have achieved weight reduction and size shrink in evaporators which act on the cooling coil. By means of all these we would be able to reduce the noise level of the ac systems and in turn the vibration of the system goes down.”

As light weight achievement is mentioned else where in the story, it is an obvious clue that the company has contributed its portion towards increasing fuel efficiency through the consumption of less power by the machine. Speaking on the eco friendliness Sabharwal pointed that, “Refrigerant is the major substance or mixture which contributes for eco friendly environment. Choice of refrigerant varies across countries and unfortunately we do not have control over that. In India last change in refrigerant has happened in 2002 and another replacement is likely to happen soon.”

To highlight, prototypes are in place for truck segments. “Indian auto industry starts to bounce back from its lean period. Though we would not be able to expect a double digit growth instantly, the growth curve will at least scale up to 6-7%. As the market experiences oasis now, we would definitely capitalise on the same,” underlines Sabharwal.

The company has its products carrying the best brand image in the world. To act on the promises and to safeguard the reliability as a partner who delivers efficient and effective range of thermal management systems, the company takes care of the complete operations. “Starting from simulation of heat load computations till the delivery of machines, we are taking care. The machines are tested and validated under simulated climatic conditions and the inputs are measured and checked for its accuracy against calibrations,” said Sabharwal. The company uses CAD, CATIA software for design generation and claim that the possible issues could very well be captured and fixed prior to investing in tools and equipments. Further more the company is constantly involved in VAVE (Value Analysis/Value Engineering) activities for product cost optimisation and design changes.

The company caters to clients like Maruti Suzuki, Tata, Mahindra, Renault Nissan and Daimler. It also has initiated prototyping for Ahsok Leyland and Tata Motors for their truck segments. Subros air conditioning machines carries with it, the warranty at par with the vehicle warranty. For a system to get delivered the process takes 1.5 years and all OEMs will address its requirement well in advance to them.
