Curran is at the forefront of material and application technology development using advanced polymers and inorganic/hybrid coatings. New advances in material provide for ultra thin (<25 micron) foul release applications for “critical service,” and Plate and Frame exchangers.
All applications are subject to Curran quality control, and critical hold points documented and reported to client. We coat shell & tube, exchanger bundles, air coolers, U tube and plate and frame exchangers; provide in-service exchange tube ID restoration; tube end coating, plate exchangers, OD tube coating; in-situ and field coating applications.
Curran 1000T – An advanced two-part 100% solids epoxy coating designed for high temperature immersion service in cooling water, some hydrocarbons and process streams. This coating is an organic/inorganic hybrid that can be applied in a single coat to 3-5 mils total DFT, when pigmented with PTFE it achieves a hydrophobic finish and provides for superior release.
Baked Phenolic – Shop applied, bake catalyzed, suitable for all cooling water services, hydro carbons, salt solutions and solvents. Immersion resistance to 365°F; applied to 7-10 mils total DFT.
Curramix 2500 – An ultra-low DFT ambient-cure coating system designed for high temperature fouling services; in lab testing found to have excellent hydrophobic & oleophobic properties, anti-coking performance, resistant to thermal cycling and is suitable for services to 1200°F. May be applied to heat exchanger tubes, plate & frame exchangers. Applied to 20-40 microns total DFT.
Sol Gel – Ceramic SiO “backbone” hybrid with organic and inorganic components, suitable for plate & frame, and tube bundles in process critical services. Applied to 20-40 microns total DFT.
