Rosemount OPM2000, OPM2000A, OPM2000R, & OPM2001 are obsolete / NLA / no longer available / discontinued

These analyzer are discontinued by the OEM but they are still VERY viable! We have parts and service available for these continuous opacity monitoring system analyzers (a.k.a., COMS). Call us today!

If you are contemplating a wholesale replacement (or upgrade) of your Rosemeount opacity analyzer, remember to weigh the pros and cons.  Here is a list of things to think about:

  OPM series is out of production Con  
  OPM series is out of production but still supported by RIGAS   Pro
       
  OPM series is virtually not supported with parts by OEM (Rosemount) Con  
  OPM series is supported with parts by a 3rd party (verified veteran owned small business) - RIGAS   Pro
       
  OEM liquid crystal windows are of poor quality or non-existant or overly priced Con  
  RIGAS manufactures good quality liquid crystal windows at a fair price   Pro
       
  OPM series is not supported technically any longer by OEM (Rosemount) (due to retirement of key individuals) Con  
  OPM series is supported technically by RIGAS.  Mel Underwood, Pat Robeck, & Larry Runyan are very knowledgeable.   Pro
       
  Calling OEM regarding OPM series is not easy; they will only converse with you during normal business hours Con  
  Calling RIGAS regarding OPM series is easy; they will converse with you 24/7/365   Pro
       
  Calling OEM regarding OPM series for an emergency parts shipment is pointless; they don't have parts on hand Con  
  Calling RIGAS regarding OPM series for an emergency parts shipment is easy; they will drive package to Cleveland Airport if necessary   Pro
       
  Operating costs (quarterly audits, annual audits, miscellaneous repairs) on old OPM units is about $15K per year Neutral  
  Operating costs (quarterly audits, annual audits, miscellaneous repairs) on any new opacity analyzer is about $13K per year   Neutral
       
  Analyzer replacment cost is about $25K plus $10K (stack modification, rewiring, etc) plus recertification $15K - Total = $50K Con  
  Analyzer nonreplacment cost is $0K - Total = $0K   Pro
       
  Analyzer replacment cost comes out of a capital expense budget not the operating budget Neutral  
  Analyzer replacment cost comes out of a capital expense budget not the operating budget - but it is still a drain on company finances Con  
       
  OPM series has been installed for many years and seems to be faulting regularly due to interconnecting wiring or aged components Con  
  If OPM series has been installed for many years, blowers, hoses, interconnecting wiring will need to be replaced (but necessary for a new installation too)   Neutral
       
  New COMS will meet current EPA regulations (but you'll still have to meet the QA criteria in 40 CFR part 60, App F, Procedure 3) Neutral  
  Old OPM COMS is grandfathered in with old EPA regulations - yes (but still needs to meet new promulgation of 40 CFR part 60, App F, Procedure 3)   Neutral
       
  New COMS will require more data points on DCS to meet current EPA regulations (per 40 CFR part 60, App F, Procedure 3) Neutral  
  Old OPM COMS is grandfathered in with old EPA regulations - yes but still needs more data points on DCS to meet current EPA regulations (per 40 CFR part 60, App F, Procedure 3)   Neutral
       
 

If replacing the COMS with a new system then you'd then be relying on an OEM that has parts & support for many years ahead

  Pro
 

If not replacing the COMS with a new system then you'd then be relying on a 3rd party vendor (RIGAS) for parts & support for many years ahead. (We, RIGAS, think that this is a good gamble; we plan to stay in the COMS business for m,any years to come.)
