ABB's AC Drilling Drive System provides the customer a ready-made solution for easy installation and excellent functionality, and includes a water-cooling system for the frequency converters, transformers and brake resistors. By selecting water-cooling, customers save space and weight as compared to traditional air-cooling systems. This in turn leads to a more cost-effective product for the customer, said ABB. The company has been a pioneer in this new drilling drive solution technology. Previously, this technique was mostly used on cruise ships. ABB said it will also will deliver 24 hours/7 days worldwide service for the facility.
