5 reasons to choose a retrofit solution
1. Cost savings
In many cases, it makes sense to upgrade outdated machinery. The advantage: Retrofit solutions are usually cheaper than replacing an entire system. This allows you to reach the same results with less money, for instance reduced downtime or improved energy efficiency.
2. Prolonged service life
By retrofitting latest-generation control and actuator systems, sensors and user interfaces, the service life of outdated machinery can be prolonged by many years.
3. Increased productivity
Retrofit solutions are remarkably cost-efficient. They help you cut down on production costs by achieving higher productivity and an increased product quality. In addition, downtime can be reduced to a minimum, ensuring significantly longer uptime periods of your system.
5. No adaption time
Compared to new systems, retrofit solutions require significantly less training as the basic functionalities of the machinery stay the same. This keeps staff training for new or improved features at a minimum.
