X-CARE - giving the ahu world a help button
Connecting customers, service, technicians and AHUs.
Industry 4.0 cannot function without a digital service concept. Differentiation from the competition is already taking place today through “more” service. Customers therefore primarily choose the partner who offers more and quicker services.
From now on, augmented reality will enable experienced personnel with appropriate digital support on site directly at the AHU to carry out qualified work without detailed knowledge about the respective AHU or AHU from Huber & Ranner. These missing details are supplied to the technician via his smartphone. In this way, qualified personnel who are not part of the service company’s staff can be integrated into maintenance management without the need for company-specific training.
It’s simple: customers expect first-class service! Better, faster and more efficient after-sales service is the secret to success for satisfied customers.
Supporting customers and partners in all phases of the equipment lifecycle is our goal. We would like to discuss with you how the best solution can look like in your building. We are giving you the help button for your AHU.
