SCELERIN is a derivation of the Latin words for “Thermal Energy”. Scelerin Heaters, L.L.C. was renamed when Bernhard Capital Partners Management, LP purchased our group in June, 2015. Previously we were Willbros Heater Services, L.L.C. Our management team and core business remains the same as when we were originally founded in 2006. Our day to day operations and business model to provide Process Fired Heater equipment and services to the oil, gas, petroleum and petrochemical industries has not changed.


An award-winning Safety Program, embraced and enforced at every level of the organization, has resulted in industry-leading safety performance.
