Miretti FilterEx a catalytic self-cleaning exhaust flame traps
The patented Miretti FilterEX system, when combined with Miretti Zone 1 and 2 exhaust gas coolers, enables Zone 2 diesel engine equipment to operate for up to 1,000 hours before the exhaust flame trap(s) are checked and eventually cleaned.
Extending operating time from 20 hours to up to 1,000 hours – by not having to service the exhaust flame traps – can have a dramatic impact on the cost of operating equipment such as air compressors, gen-sets, pumps, cranes and wireline units.
What’s Miretti FilterEx and how does it work?
It’s a ‘compact’ exhaust cooling system with integral self-cleaning exhaust flame arrestors. FilterEx systems have recently been certified by CEC to ATEX 94/9/EC and for EN 1834:2000 Parts 1, 2 and 3;
It’s an innovative system which enables maximum engine ‘uptime’ as the self-cleaning flame arrestor can operate for approx. 1,000 hours before cleaning;
It’s an alternative approach that reduces costly service maintenance when conventional exhaust flame arrestors need to be changed every 20 hours.
What is it and how does it work?
Miretti CoatEx provides a thermal barrier between hot engine surfaces (e.g. turbochargers and exhaust manifolds) and the external atmosphere.
Enables the OEM “dry” turbocharger and manifold to be retained reducing Zone 2 conversion costs and minimising risk of failure by fitting non OEM turbo and water cooled manifold.
Using Miretti CoatEx, all the original EPA listed components are used, keeping unchanged the functioning of the components.
All the original functioning of the components will be kept unchanged. The maintenance time is the same of what the OEM recommend. Very quick and simple operations are necessary during the service
Removing the CoatEx just from interested the bolts and clamps;
Remove the part from the engine and replace with a new one already coated;
Cover just the bolts and clamps by new the Service & Repair CoatEx Kit.
Cost of “passively” protecting Zone 2 diesel engine oilfield equipment with complex control systems and cost of downtime and service maintenance of cleaning exhaust flame traps every 20 hours.
Provides gas detection and automatic engine/equipment shutdown for almost any Zone 2 application onshore and offshore.
3GMIR uses infrared gas sensors for robust duty and extended life and has self-calibration capability. Ensures maximum safety and eliminates the need for exhaust flame traps and equipment “down-time” caused when cleaning conventional exhaust flame traps.
Cost and complexity for modification and compliance of oilfield and engine equipment electrics to different global/regional standards of explosion protection.
Unified compact engine control system approved worldwide under ATEX, NEC (FM), IECEx.
Zone 2 electronic controlled system for oilfiel equipment ensures simple installation and operation. It is compact and is approved worldwide.
Cost of “passive added-safety” for diesel engine and electric battery equipment operating in unclassified areas and risk that equipment continues to operate with explosive atmosphere present.
It’s a cost effective protection for a multitude of applications.
It’s a basic kit of parts that can be installed locally to provide gas detection, visual/audible alarms and automatic equipment shutdown at 25% LEL Propane in Air.
All Miretti Ex Solutions Diesel Engine Hazardous Packages are certified in compliance with ATEX 2014/34/EU, IECEx, CNEx, NEC 500, EAC Ex standards and regulations.
Miretti’s Ex Kits and Ex Systems for diesel engines include features designed, tested and certified to prevent an ignition source causing an explosion supporting the equipment of our clients.
The explosion proof conversions of area classified provide the electrical and mechanical protection of the diesel engine, removing the risk of explosive ignition.
