ACCU-DRIVE Damper Drives

damper-drive-supplierSEMCOR 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.
