Thermal system

The Thermal Systems business was established in 1996, with a keen eye to manufacture Auto Air Conditioners for leading car brands Toyota and Suzuki in Pakistan. Operations subsequently grew to encompass Heater Blower and Air Conditioner Controls. This was followed by the induction of Heater Core, Condensers and subsequently Thal Engineering became the only company to manufacture Aluminum Radiators for automobiles in Pakistan.

From the very inception of the Thermal division, Thal Engineering has maintained its superiority and product quality by focussing on delivering the best in class. In 1996, a Technical Assistance Agreement was signed with Denso Japan – the second largest auto parts maker in the world, listed on the Fortune 500 and also the largest in Japan. This strategic alliance paved the way for Thermal Systems division to continue the uninterrupted manufacture and supply of auto parts enabling millions of journeys every day.

A strategic partnership between Thal Engineering and Denso Corporation, Japan led to the establishment of the Engine Component Business (ECB). A relatively new addition to our portfolio, this division started by manufacturing Starters and Alternators for Toyota vehicles in July 2014.


Thal condensers match up to OE condensers at every benchmark. Multiflow, subcooling, and the latest Serpentine condenser styles are offered to provide the optimum configuration for each application. Premium aluminum construction improves reliability, resisting corrosion to avoid expensive system leaks, while the superior fin wave design offers higher heat transfer and maximum refrigerant condensation. Heat exchanger cores are specially designed to shed airborne material buildup, allowing the A/C system to operate at peak efficiency with minimal maintenance, assuring years of trouble-free service.

Starter Assembly

Thal has the inside track on starter technology. The original Thal gear-reduction starter is an industry benchmark, so rugged and powerful that it is often adapted. Thal manufactured starters are subjected to a rigorous test and replacement routine that produces the lowest return rates in the replacement aftermarket. Armatures and field coils are high-voltage tested; commutators are refinished and performance-validated; terminals and fasteners are replaced with high-quality copper components. And every starter is exactingly bench-tested to ensure maximum performance.

Alternator Assembly

Thal’s alternators are not only original equipment on many of the Pakistan’s top production cars; as their light weight, high efficiency, and durability under the most grueling conditions make them the natural choice.

Electrical system

In the year 2000, Thal Engineering signed a Technical Assistance Agreement (TAA) with Furukawa Electric Company, Japan – one of the leading suppliers of automotive wire harness systems in the world with more than 50 subsidiaries operating in twenty countries. Through this partnership, the Electrical Systems division of Thal Engineering was born and has since established itself as the leader in the manufacture of car wiring systems that are readily supplied to all automobile companies in Pakistan.
Following this success, Thal Engineering signed yet another Technical Assistance Agreement in 2018 with Yazaki Corporation to further expand its footprint as the premier supplier of automotive wire harness systems in Pakistan. Yazaki Corporation of Japan lends its expertise to this enterprise as a leading automotive component manufacturer in markets across the world. With plans to dominate the manufacture of wire harness systems, Thal Engineering recently set up its plant at Port Qasim, Karachi to enhance its production capacity and maintain its leadership position.
