ASME, CRN & 3‑A Compliant Solutions

Engineered assurance for safe, hygienic and reliable production

At WILA, compliant solutions are developed for operations where documented safety, hygienic integrity and predictable performance are essential. Compliance is not an added label; it is the result of controlled engineering processes, validated materials, qualified fabrication procedures and independent oversight.
When stability and compliance matter, equipment designed in accordance with ASMECRN or 3‑A requirements provides a dependable foundation for long‑term operation.

ASME Compliance

Engineering discipline supported by independent inspection

ASME pressure test of Membrane housing

The ASME Boiler and Pressure Vessel Code (BPVC) Section VIII, Division 1 is one of the world’s most recognized frameworks for the design and fabrication of pressure‑retaining equipment.
WILA is authorized to manufacture equipment built in accordance with ASME VIII‑1.

Equipment meeting ASME VIII‑1 requirements carry the ASME U‑designator and the ASME Single Certification Mark, applied only after the required independent inspection.

Producing ASME‑compliant equipment requires:

  • Precisely calculated design according to ASME VIII‑1 rules
  • Fully traceable materials meeting ASME specifications
  • Welding performed under qualified procedures
  • Surface preparation that supports corrosion resistance and long‑term durability
  • Hydrostatic testing above the allowable working pressure
  • Final review and acceptance by an Authorized Inspector

Equipment built in accordance with ASME VIII‑1 requirements provides predictable mechanical integrity, verified pressure performance and thorough documentation for audits and regulatory environments.

CRN Registration

Mandatory provincial approval for the Canadian market

A Canadian Registration Number (CRN) is required for pressure‑retaining equipment installed in Canada.
WILA provides CRN‑registered membrane housings and tubular heat exchangers designed to meet the requirements of CSA B51 and the applicable ASME sections.

WILA has now achieved nationwide CRN registration across Canada for the following membrane housing types:

MHCU 79 600

MHCU

MHCUA 79 600

MHCUA

These housings are designed for 7.9″ membranes with design pressures of up to 600 PSI. The MHCUA 79 600 model is additionally 3 A certified, making it suitable for hygienic and sanitary applications.

CRN registration confirms that the design has been reviewed and accepted by the relevant provincial safety authorities and allows legal installation throughout Canada.

CRN registration includes:

  • Detailed design review by provincial safety authorities
  • Verification of compliance with CSA B51 and referenced ASME rules
  • Confirmation of material traceability, welding quality and pressure testing
  • Registration within each province where the equipment will be installed

CRN registration ensures legal installation, consistent safety compliance across provinces and reduced administrative complexity for customers operating in multiple Canadian regions.

3‑A Sanitary Design

Hygienic performance for food, beverage and pharmaceutical applications

WILA’s tubular heat exchangers and membrane housings are also available with a 3-A compliant design and finish. These are engineered according to 3‑A Sanitary Standards, which define the hygienic requirements for cleanability, geometry, surface quality and material suitability in process equipment.

3‑A sanitary design is based on:

  • Smooth, crevice‑free product contact surfaces
  • High‑grade stainless steel resistant to cleaning chemicals and thermal cycling
  • Welds and internal geometries suitable for CIP/SIP cleaning
  • Fully drainable layouts that minimize microbial risk

3‑A compliant design supports hygienic consistency, reduces contamination risk and helps customers meet regulated requirements within food, beverage and pharmaceutical production.
