In addition to producing stand alone heat exchangers, KALE has also undertaken the role of a system integrator in recent years, by moving into the production and assembly of HVAC (Heating & Ventilation and Air Conditioning) systems. Locally operating global vehicle manufactures in Turkey, as elsewhere, demand more service and system support from suppliers and as a result, KALE has repositioned itself in recent years by making technical agreements with internationally reputable companies and investing in technologically advanced production lines to supply HVAC systems.
