ACCU-DRIVE Damper Drives
SEMCOR manufactures a proprietary line of damper drives under the ACCU-DRIVE name. Powered by a Kinetrol Vane Actuator — one of the most durable products on the market today — and featuring a Moore 760 positioner, as well as our own mounting hardware, the ACCU-DRIVE product is an all-in-one damper drive suitable for a wide range of applications.
Use ACCU-DRIVE products in any situation where you would use a standard damper drive, including for boiler, burner and turbine control in power plants, oil and gas refineries and other industrial operations. Whatever the task, you can count on ACCU-DRIVE to deliver seamless integration with your existing equipment, as well as exceptional reliability even in high-heat applications.
Like all products we sell, ACCU-DRIVE damper drives can be modified or customized to meet your individual specifications. Keep reading to learn more or contact a SEMCOR representative directly for more information.
Benefits
- Highest Reliability: The Kinetrol Vane Actuator has only one moving part — the vane itself! There are no O-rings to wear or fail. No gears or levers are used, therefore, eliminating backlash and torque loss. The end result is accurate positioning with the lowest cost of ownership.
- No Obsolescence: The Kinetrol Vane Actuator has depended on the same performance proven design for over 35 years.
- Ease of Installation: The retrofit ACCU-DRIVE floor-mount stands are designed to match the footprint and connecting rod X-Y-Z coordinates of the existing damper drive output shaft. This eliminates the need for additional field fabrication or engineering.
- Select the Most Economical Solution: Choose from eight ACCU-DRIVE size selections. Available torque range spans from 90 to 9,333 foot-pounds with 45 to 180-degree rotation.
- High Temperature Operation: 185˚F standard with higher temperature options available.
Standards
- Actuator: The Kinetrol high-performance vane style pneumatic actuator, properly sized for the appropriate service safety factor.
- Mounting Hardware: The ACCU-DRIVE stand is fabricated from heavy carbon steel and protected with a baked on polyester powder coating to 3 mils D.F.T. The splined output shaft, fasteners and tubing are type 304 stainless steel. All stand bearings are heavy duty rated, sealed for life, suitable for washdown service and have electroless-nickel plated steel housings for superior corrosion resistance. Standard equipment includes a Norgren 5-micron air particulate filter/regulator with gauge and auto-drain.
- Positioner: The ACCU-DRIVE standard pneumatic positioner is the Moore Model 760 with customer’s specified input signal and feedback (3-15 PSI, 4-20mA, 0-10VDC). The Moore positioner also includes gauges, speed adjusters and position indicator.
Options
- Arrangements: Direct mount to damper drive shaft or floor mount.
- Manual Overrides: Lever with locking plate or declutchable handwheel gearbox.
- Feedback: Mechanical or proximity limit switches and/or 4-20mA feedback.
- Positioners: Although the Moore Model 760 pneumatic positioner is standard, the customer can specify their plant standard.
- Air Failure Lock-ups: This option will lock up damper in last position upon loss of predetermined air pressure.
Application Engineering and System Integration
ACCU DRIVE units are often installed in environments where precise airflow control directly affects combustion efficiency, emissions performance, and equipment longevity. SEMCOR supports these installations by helping facilities evaluate how damper drive responsiveness, torque output, and control signal behavior interact with upstream and downstream components. This includes reviewing actuator sizing, stroke requirements, mounting orientation, and feedback needs to ensure that each ACCU DRIVE assembly integrates smoothly into the plant’s existing control architecture. This engineering support helps reduce commissioning time and supports consistent performance across demanding applications.
Performance Optimization for High Demand Environments
Industrial operations that rely on continuous modulation benefit from equipment that maintains stable performance under variable loads. SEMCOR assists customers in identifying configuration options that support smoother transitions, improved positioning accuracy, and reduced wear on connected equipment. This may include evaluating cycle frequency, air supply quality, ambient temperature, and vibration exposure. By aligning ACCU DRIVE configurations with real world operating conditions, facilities can improve process stability and reduce the likelihood of unplanned maintenance events.
Long Term Maintenance Planning and Reliability Management
Although ACCU DRIVE assemblies are designed for durability, long term reliability still depends on proper maintenance planning. SEMCOR helps customers develop strategies that include inspection intervals, air supply monitoring, positioner calibration, and spare parts planning. Understanding how damper drives behave over time allows teams to schedule service proactively and maintain consistent airflow control. This approach supports better operational continuity and helps facilities manage lifecycle costs more effectively.
