Diesel Engine Exhaust Spark Arrestors
Designed especially to meet the requirements of the latest generations of low emission diesel engines (NRMM stage III A / B, stage IV and V; equivalent US Tier 3 & 4 : Euro 5 and 6 (other harmonised standards) and engines fitted with exhaust treatment devices such as DOC (catalysts) DPF (particulate filters) and SCR (NOx abatement) Post 2014
Operating Principle
Chalwyn spark arrestors are the quenching type as defined in BS EN 1834-1:2000 clause 5.10.2. In this cyclonic design the glowing particles emitted from a diesel engine exhaust are spun and repeatedly impacted against internal spark arrestor surfaces. This cools them and breaks them down before eventual safe discharge to atmosphere.
Features and Benefits
- Standard Spark Arrestor versions are safe to use where a stray spark from a diesel engine exhaust may ignite surroundings or cause an explosion
- ATEX Spark Arrestor versions are safe to use in potentially explosive atmospheres (the 316L range meets EN 1834 requirements)
- For use as a mandatory requirement globally in the oil and gas industry
- Constructed from corrosion resistant 304L stainless steel or 316L stainless steel for ATEX approved versions, the material is robust providing longevity
- Wide range of sizes available
- Meets engine manufacturers published back pressure specification providing emission conformance, and exceptional spark-arresting abilities
Exhaust gas flow rates and back pressure limits vary between engine manufacturers. Please consult us with your requirements for further information
