Part Categories

Chemical Filters

As a routine consumable product within the process high quality filters are critical. We provide design-appropriate filters and replacement housing units as well.

Heat Exchangers

We provide in-kind replacements as needed for heat exchangers within the process. Primarily components and occasionally entire vessels are rebuilt. ERCO stocks speciality-grade titanium tubes to reduce extensive lead times.

Miscellaneous Titanium

The reactive, abrasive, and corrosive nature of the process is such that it wears out spool pieces in joints and elbows, replacing these pieces with specialty grade titanium by the OEM in a timely manner is crucial for safe operations.

Saltcake Filter

The Saltcake Filter System is a special component in ERCO's R8/10 design. The rotating drum assembly is unique to our process and as such requires OEM replacements. This includes Filter cloths, ware and timing plates, or more extensive rebuilds.


The absorption and stripping columns are two FRP components of the process, spare parts here include packing materials, support rings and distribution trays.

Gaskets and Seals

ERCO will supply OEM replacement Gaskets for operational or routine maintenance purposes. We also support our R-Series generators with Teflon nozzles and seals for use in the filter drum assembly.

When you do need replacements, ERCO ensures parts that are suitable for the process conditions; that meet the original specification design intent of the process; and that meet all applicable codes and standards.
