Leaders in Gas Scrubbing
Custom Fabricated Scrubbers for Industrial Gas Treatment
ERG Hygrade has been manufacturing high-integrity gas scrubbing equipment since the 1970s, earning a strong reputation for fabrication quality, reliability, and technical excellence.
We specialise in the design and build of custom plastic scrubbers for removing hazardous or unwanted contaminants from process gas streams — whether for emissions control, operator safety, or process compliance.
No two applications are the same, which is why we don’t offer off-the-shelf systems. Every scrubber we fabricate is tailored to the duty — with guaranteed performance, low operating costs, and long service life.
Focused Design
Hygrade manufactures a full range of scrubber types, available in thermoplastics or GRP construction:
-
Packed Tower Scrubbers
-
Venturi Scrubbers
-
Gas Absorbers and Stripper Columns
Each unit is fabricated to suit your specific gas flow, contaminant type, temperature, and required removal efficiency. We work to BS EN 13121-3 standards, with laminate testing and commissioning offered where specified.
Relining & Refurbishment Services
Scrubbers often operate under aggressive chemical and thermal conditions, making preventive maintenance and relining essential for long-term reliability.
ERG Hygrade offers cost-effective refurbishment options, from minor patch repairs to full overhauls including:
-
Replacement internals

New fans and pumps
