Successful fire test performance secures major order for Rotork actuators
The order from a local damper manufacturer is for RC200 high temperature pneumatic actuators for installation on the fully underground sixth section of the MRT line. In addition to ventilation, the dampers are designed to provide vital safety related duties in the event of a fire.
To verify compliance with the critical operating demands of the application, an RC200 actuator was subjected to stringent testing which involved heating to an ambient temperature of 250ºC for two hours, followed immediately by a one cycle functional test. The fire test was witnessed by the customer, the contractor and the MRT end-user, the Land Transport Authority of Singapore. A separate test was carried out by a third-party organisation to confirm the actuator’s ability to perform one million cycles.
Rotork RC200 high temperature pneumatic actuators offer a fast operating capability and long term reliability with minimum maintenance. The compact scotch-yoke design performs in the high temperature environment without the addition of external fireproofing coatings.
The actuators are fully supported by the Rotork Centre of Excellence in Singapore, where spare parts are stocked for maintenance purposes. A local stock of actuators is also available for potential future upgrades of dampers installed on previous phases of the MRT line.
