Isışah

ISI ŞAH Industrial brand has been collaborating with the railway industry since 1982. During the 80s and 90s, it worked as a supplier to Tüvesaş and Tülomsaş. Initially, it produced heating rods and heating units with enclosure sheets containing heating rods for many years. In this field, it also began producing switch heaters, which are also important in railways. In the 2000s, ISI ŞAH identified that heating rods were insufficient for trains. As a result of ISI ŞAH's R&D efforts, the heating system was redesigned, and thanks to heating units placed under the chassis, it became a system that could measure and deliver the required amount of hot air into the wagon.

Thanks to advancements in technology, heating systems are now integrated with cooling systems and are being installed on top of trains as air conditioning units. In this context, ISI ŞAH continues to serve its domestic and international customers with its in-air conditioning heating units.

ISI ŞAH's heating units continue to be used in intercity high-speed trains, subways, and trams, both within air conditioning units and as under-seat heating units.
