Draft Regulator with Linear Actuator

 

The Preferred HC-09502-1012 is a linear actuator with an integral microprocessor-based draft controller and a solid-state draft range pressure sensor. This is an upgrade replacement for the CDR.

  • Housed in a durable metal enclosure with a removable cover.
  • Provides automatic modulation for any negative or positive draft application.

Overview and Features

The HC-09502-1012 is housed in a durable metal enclosure with a removable cover. The HC-09502-1012 is a direct replacement for the Hays Cleveland model # 9502-1012-B-8. The HC-09502-1012 provides automatic modulation for any negative or positive draft application. Specifications Weight & Dimension: 21 lbs. 17.5” L x 7.5” W x 5.9” H Power Requirements: 120 VAC, 50/60Hz Motor: 72 RPM synchronous motor Sample Connection: ¼” NPT female fitting Ambient Temperature Range: 0 to 140F (-18 to 60C)

  • Offers a 6-inch range of travel with a 60-second nominal stroke time. The HC-09502-1012’s thrust range is rated at 150 lbs with a cool-running 72 RPM synchronous motor.
  • The actuator is self locking in the “last” position if there is a power loss.
  • Preferred’s HC-09502-1012 interfaces with your burner management system:
    • The HC-09502-1012 is a sequencing draft controller.
    • Includes burner management interfacing relays for automated Open damper during Purge, and Closed damper after shutdown.
    • Includes an Automatic/Open selector switch. This allows the user to blow soot without interrupting the burner firing and allows the burner to fire in the “Open” damper mode under emergency conditions.
  • Sensing and control functions offered via the PID controller are as follows:
    •  A solid state sensor provides an accurate, low drift signal to the controller.
    •  Field-adjustable Set Point for both positive pressure and negative draft applications.
    • Adjustable Sensor Dampening to reduce the effects of flame induced draft pulsations.
    • Adjustable Proportional Band for control of the rate of actuator movement in relation to the set point.
    • Adjustable Dead Band to prevent actuator “hunting” near the set point.
