improve overall machine efficiency.
The optimization of vacuum systems goes hand in hand
with comprehensive service agreements, ensuring that these
systems continue to provide substantial energy savings and adapt
automatically to machine needs. While RunEco EP Turbo Blowers
are cost-effective to maintain and operate, scheduled maintenance
is recommended to guarantee uninterrupted operation and longevity.
Routine audits and optimization checks are vital to ascertain that the
vacuum system functions at peak performance.
Given the high degree of airflow and potential contaminants
in the process, vacuum systems operate under demanding
conditions. Particular care is needed, especially where the mill
water circuits are fully closed, to prevent the accumulation of
contaminants. Cleanliness is crucial for optimal performance and
runnability, not only for the vacuum system but across the entire
papermaking process.
Streamlined Maintenance with RunCare Agreements
Runtech offers RunCare Agreements, comprehensive
service contracts that simplify maintenance, manage costs, and
boost vacuum system efficiency. These customized agreements,
which include an extended warranty and span 5–10 years, ensure
that vacuum systems operate optimally with minimal effort required
from mill staff.
RunCare provides scheduled maintenance aligned with
production plans, fixed service costs, and around-the-clock
assistance. The service extends to in-depth inspections of all
vacuum system components, aiding in precise budgeting for
potential part replacements.
“We began by evaluating the customer’s
energy efficiency, testing the impeller
at various operational points.
The active magnetic bearing system,
paired with the Magma controller, enabled
effective testing and data collection for impeller
redesign.
Consequently, the updated impeller has
improved system efficiency and confirmed
robust performance throughout the turbo
blower’s entire operating range.”
Alexander Smirnov, CTO and co-founder of SpinDrive,
Already favored by 30% of Runtech’s clientele, the RunCare
concept is gaining traction due to its focus on addressing customer
challenges effectively. Routine services and audits by Runtech’s
experts are critical for the smooth operation of paper mills, offering
insights into potential improvements and the overall health of the
equipment. These evaluations are integral to enhancing energy
efficiency, reducing emissions, and optimizing production, starting
with a thorough understanding of the papermaking process and its
nuances.
