The answer depends on a distinction that is easy to miss. Hamon organized its air pollution control activities into two separate organizations, which ultimately went in different directions.<\/p>\n\n  <h2>Two organizations, documented by Hamon<\/h2>\n  <p>Hamon's annual reports separated the activity into two business units:<\/p>\n\n  <div class=\"sb-two\">\n    <div class=\"sb-col\">\n      <h3>Air Pollution Control &amp; Heat Recovery - NAFTA<\/h3>\n      <p>The North American organization (United States, Canada, Mexico), operating through Hamon Research-Cottrell, Inc. Strong in power generation, utilities, coal, steel and refining.<\/p>\n      <p>Signature technologies: Hi-R electrostatic precipitators, MIGI rapping, Low Pressure High Volume (LPHV) baghouse filters and a large US utility installed base.<\/p>\n    <\/div>\n    <div class=\"sb-col\">\n      <h3>Air Pollution Control - EMEA \/ Brazil<\/h3>\n      <p>The European-led organization, headed by Hamon Research-Cottrell SA in Belgium, covering Europe, the Middle East, Africa, South America and a growing Asian market through a network of subsidiaries.<\/p>\n      <p>Documented centers of excellence: ESP and DeSOx in Belgium and Germany, baghouse filters in China and an engineering centre in India.<\/p>\n    <\/div>\n  <\/div>\n\n  <h2>Where each organization went in 2022<\/h2>\n  <p>The assets of the US entity, Hamon Research-Cottrell, Inc., were acquired by Babcock &amp; Wilcox through a Chapter 11 asset sale in the United States. Babcock &amp; Wilcox owns the assets of that North American business.<\/p>\n  <p>The European organization - <strong>Hamon Research-Cottrell SA<\/strong> (Belgian enterprise number BE 0401.881.292, incorporated in 1929) and Hamon Environmental Europe - was not included in that acquisition. Its engineering expertise, project records and former engineers are now at Studybel and Leroux &amp; Lotz Technologies.<\/p>\n\n  <h2>Addition, not substitution<\/h2>\n  <p>The European organization was not a regional copy of the American organization. It had fully mastered the American-origin Hamon Research-Cottrell technologies - Hi-R and MIGI electrostatic precipitators, electrodes, collecting plates, HV frames, insulators, rappers, T\/R sets, controllers and gas distribution - and delivered, retrofitted and rebuilt them worldwide outside North America. On top of that base, it added its own European technologies:<\/p>\n  <ul>\n    <li>Compact electrostatic precipitators<\/li>\n    <li>Mechanical rotating \/ tumbling-hammer rapping systems (shafts, anvils, geared motors)<\/li>\n    <li>Medium-pressure pulse-jet baghouse filters, in addition to LPHV<\/li>\n    <li>Complete chemical flue gas treatment (dry and semi-dry; lime and bicarbonate injection; activated carbon; HCl, HF, SOx, dioxins and heavy metals)<\/li>\n    <li>DeNOx<\/li>\n    <li>Turnkey multi-pollutant systems for waste-to-energy, incineration and biomass<\/li>\n  <\/ul>\n  <p>The European organization therefore covered the broader technology and market scope - American-origin heritage + European technologies + a worldwide network - while the North American organization was a strong but regional business. Acquiring the US entity does not, by itself, confer compact-ESP and tumbling-hammer know-how, waste-to-energy and biomass expertise, or responsibility for markets outside North America.<\/p>\n\n  <h2>What this means for your installation<\/h2>\n  <p>For a Hamon Research-Cottrell or Hamon Environmental installation outside North America, the original engineering was produced by the European organization. Studybel:<\/p>\n  <ul>\n    <li>Audits, troubleshoots and diagnoses these installations<\/li>\n    <li>Supplies parts to the original design, based on the direct experience of former Hamon Research-Cottrell SA engineers and the available technical documentation<\/li>\n    <li>Reverse-engineers obsolete or undocumented components<\/li>\n    <li>Performs retrofit, modernization and rebuild work, with EPC execution through Boccard and combustion-to-stack integration through Leroux &amp; Lotz Technologies<\/li>\n  <\/ul>\n  <p>Studybel does not claim OEM status or rights to the Hamon Research-Cottrell trademark. Its position is based on the European engineering heritage and the people who carry that expertise today.<\/p>\n\n  <div class=\"sb-cta\">\n    <a class=\"sb-btn sb-btn-primary\" href=\"https:\/\/studybel.com\/en\/hamon-environmental-research-cottrell-legacy-support\/\">Hamon legacy support<\/a>\n    <a class=\"sb-btn sb-btn-secondary\" href=\"https:\/\/studybel.com\/en\/contact\/\">Contact Studybel<\/a>\n  <\/div>\n\n<\/div>\n\n<!--\n================================================================================\n JSON-LD - insert via WPCode in the <head> of THIS page only\n================================================================================\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"TechArticle\",\n  \"headline\": \"Hamon Research-Cottrell: the US company and the European organization are not the same\",\n  \"about\": \"Distinction between Hamon Research-Cottrell, Inc.
