Since 1877, the way Kiefer thinks and acts has revolved around optimum solutions and products. The aim has always been to create ventilation and air-conditioning technology that is fit for people, does not harm the environment and saves energy – and today more than ever. Our customers' satisfaction is very important to us. This means that we are on hand during every phase of the project: from the initial sketch through the finished project all the way to installation and maintenance services.
