The components of ice machines are obtained from renowned suppliers (e.g. Bitzer, Bock, Danfoss, Siemens etc.) or produced by specialist companies in the area of Hannover. They are subject to strict goods-in checks.
The customer service department has had special importance since ZIEGRA was founded. The domestic customer service department has, amongst other things, mechanics that have trained with ZIEGRA machines and have maintenance vehicles including all the necessary tools. The multi-lingual foreign customer service department is assisted by experienced ZIEGRA mechanics as well as customer service departments at the subsidiaries in England and Spain and a maintenance network of partners in Europe and other continents. Fast help by telephone, fax or E-mail is also tried and tested.
Spare parts at ZIEGRA are guaranteed to be available for a period of at least 15 years, which is also an indication of the long life-span of the machines "IceTechnology - made in Germany".
