Blow In Doors
We supply Blow-In Doors to complement our 2S systems in Gas Turbines’ projects.
By partnering with a UK-based OEM with decades of experience, we are able to supply 2 designs:
- Mechanical tuning of pressure drop
- Advanced Electronic tuning of pressure drop with simplified installation
Mechanical Design
Features
- The blow-in doors open automatically when the Dp reaches 140 mmH2O, with possibility to tune between 114 mmH2O and 406 mmH2O
- Estimated weight = 18kg
- Overall dimensioning 585mm x 585mm
- Aperture opening 444mm x 444mm
- Angle of door opening 56°
- The blow-in doors are anodized
- Provided with an integrated Junction Box to manage heating power and signals (min IP56)
- Power Consumption max 1.15kW (5Amp)
- The feedback of the door position is sent from an external micro-switch with low power consumption (1uA to 100mA @ 1 to 50V ac/dc)
- The tuning of pressure drop value for the blow-in door opening can be done from the upstream side of the door (door needs to be open)
Advanced Electronic Design
Features
- See Mechanical Design above plus
- The Dp can be tuned remotely from the Turbine Control System (TCS) with a simple DC 12V input to a Junction Box of our supply
Integration
We are able to supply additional Junction Boxes (typically M20, IP66) in order to integrate the Blow-In doors with the ship’s feedback and control system.
