Chemical Cleaning – Descaling


Spanchem Technologies efficiently removes fouling deposits from heat transfer equipment, boilers, and other industrial equipment by circulating chemical solvents under controlled temperature, pressure and time conditions.

Spanchem Technologies leads the industry in pre-operational and operational chemical cleaning with over 15 years of experience. This plays a vital role in assuring that the plant and product specifications will be met at the very outset of facility start-up and throughout the operational cycle. The facility will operate smoothly, efficiently, and on schedule. Troublesome and costly start-up difficulties due to undesirable deposits are eliminated.

We custom engineer each individual chemical cleaning job to provide a complete, high quality cleaning service. We analyze your equipment, processes, and deposits to design a cleaning process to fit your individual plant needs and select the optimal cleaning solvent system.

A series of chemical cleaning centrifugal pumps, specialized chemical hoses, heating units, filters and chemical mixing tanks are typically used to establish optimal circulation loops.

Each chemical cleaning project is custom engineered to deliver optimal treatment, taking into account:

  • Deposit Sample Analyses
  • Solvent/Metallurgy Compatibility
  • Process Loop Geometry
  • Fluid Flow Velocities
  • • Pressure Drop Considerations
  • Process and Chemical Handling Safety
  • Waste Minimization and Disposal

We combine a wide variety of chemicals, including proprietary blends, with techniques such as circulation, fill-and-soak, cascading, foaming, rotating spray systems, and vapor phase cleaning to achieve superior performance and results.

Our services cater to a wide range of heat transfer equipment including: Marine Boilers, Lube Oil Coolers, Condensers, Evaporators, Compressor Jackets, Intercoolers/Aftercoolers, Pump Jackets, Chilled Water Cooling System, VHP Systems, Air Handling & Fan Coil Units, Shell & Tube Heat Exchangers, Double Pipe Heat Exchangers, Plate Type Heat Exchanges, Waste Heat Boilers
