Clima Tech is ZAC's brand for special application air-handling units.

Controlled and operated by Zamil Air Conditioners, Clima Tech was acquired by Zamil Industrial Investment Company (ZIIC) in the year 1999, its first business entity out of Saudi Arabia. The acquisition followed successful business alliances between the two companies on a number of projects since 1986. One of the most prestigious projects jointly carried out by Zamil Air Conditioners and Clima Tech is the supply of air handling units to the Prophet's Mosque in Madinah, Saudi Arabia - one of the largest air conditioning projects in the world.

CLIMA TECH Airconditioners GmbH, headquartered in Grunbach – Austria, specialises in development and manufacture of technology based air-handling units and related high–quality components for the hygiene, climate and clean room applications. These are usually installed in the high sterile areas such as the OT rooms in hospitals, procedure technical plants, pharmaceutical clean rooms, electronic clean rooms, foodstuff production, universities, power plants and industrial projects as well.

The acquisition of Clima Tech has greatly enhanced the product line of Zamil Air Conditioners, while also helping it position one step closer to the new and expanding markets in Europe and Latin America.

 Clima Tech is a 35-year-old company and its experience in its line of business places it among the most reputed names in Europe. Responding to increasing demand for its products, the company recently converted its branch office in Germany into an independent company and named it to KESSLER CLIMA TECH GmbH.

The sales and marketing operations at Clima Tech are organized into four divisions: Sales – Austria, Sales – Europe, Sales – Exports, and Sales – Cooline Products.

 While the Austria sales are handled by the company’s own staff and in Germany by the independent subsidiary Kessler Clima Tech, Clima Tech operates through a network of business partners in other European Markets, Middle East and Asia.
