Q-Rohr DFE offshore Product Information

Product catalog summary

Introduction
The document provides detailed information about the Q-Rohr® DFE, a flameless explosion venting system designed for dual-fuel engines, particularly in maritime applications. It addresses new challenges posed by IMO regulations aimed at reducing sulphur and nitrogen emissions.

Specifications
The Q-Rohr® DFE is lightweight and compact, making it suitable for installation in confined spaces. It offers 100% venting efficiency and is made entirely of stainless steel for corrosion resistance. The system is certified by maritime classes such as DNV-GL, LR, BV, and ABS.

Technical Data

Burst pressure: 0.1 to 0.5 bar
Operating temperature: −10 to +550 °C (14 to 1022 °F)

It includes components like an explosion-proof housing, reusable stainless steel filter, and integrated explosion vent with a signalling unit.

Advantages

Flameless pressure venting in the ship’s hull
100% seal tightness to prevent asphyxiation
No maintenance required, only visual inspection
Noise reduction during normal operation and explosions

Challenges and Solutions
The document highlights the risk of explosions due to flammable gas mixtures in dual-fuel engines and presents the Q-Rohr® DFE as a cost-effective solution to mitigate these risks, ensuring rapid restart of operations post-explosion.
