A one stop shop to all paper machine dewatering solutions and services
Vacuum system optimization and lower energy consumption start with the EP Turbo Blower. Completely water-free RunEco solution with Turbo Blowers is a fully adjustable, energy-efficient vacuum system for tissue production. It is a tailor-made solution equipped with optimal save-all and doctoring system and online dewatering measurements. RunEco can provide energy savings of 30 to 70%, and is applicable for both greenfield and rebuild projects. Mills have reported that vacuum system optimization with variable speed and capacity turbo blowers have saved them up to 2,000 kW. Together with Nash, another Ingersoll Rand brand, and the original innovators in liquid ring technology, we are the only company in the world that can supply both liquid ring pumps and dry vacuum systems, or a combination of them, for a so-called hybrid system. In addition, we offer doctors and save-alls, making our offering complete for paper machine dewatering. With this unique portfolio, we can always find a perfect fit for our customer’s demands, needs and budget.
Hybrid vacuum system
A typical Runtech RunEco vacuum system consists of several smaller size turbo blowers giving clear design and operational advantages over the competition. Quite often a situation has been observed where a single, or a few low air flow consumers (devices) are operating at high vacuum levels, such as a high vac box or a press suction roll high vacuum zone, while the rest use a considerably lower vacuum level. This leads to a situation where the most economical option is to continue the use of the existing Liquid Ring Pump (LRP). Fully rebuilding a system with blower technology is not always the most efficient solution, especially if this means that different vacuum levels need to be combined in one blower. It is proven that a well maintained LRP operating at low speed to produce high vacuum level can perform at a good efficiency level outperforming systems where a large single blower experiences considerable expansion losses.
