Curramix 2500 is an advanced single-part ambient-cure anti-coking ceramic coating engineered specifically for high-temperature metal substrates operating up to 2000°F (1093°C). A durable, thin-film coating engineered to protect critical exchanger surfaces in severe fouling environments. This state of the art coating technology delivers exponential improvements in thermal cycling and anti-coking properties for heat exchanger tubes (ID & OD), tube sheets, channels, and components.
Offshore platform condensate stabilizer without maintenance
Reduced from 3 annual cleanings to zero per year
Thermally cycled performance capability
Heat exchangers in FCC bottoms/slurry and crude heater service experience severe fouling, forcing annual cleaning cycles and reducing thermal efficiency by 45-75% within 6-18 months.
Typical performance loss within 200 days
Curramix 2500’s ceramic matrix provides exceptional foul-release properties and thermal shock resistance, maintaining heat transfer performance for 2+ years without cleaning interventions.
Efficiency maintained after extended operation
Proven 2+ year operation without maintenance in condensate stabilizer service at 350°F
93% performance retention vs. 75% degradation in uncoated exchangers after 20 days
2000°F thermally cycled capability for crude heaters and high-temperature process exchangers
Requires only low-pressure cleaning vs. high pressure hydro blasting and aggressive mechanical cleaning.
