HYDRONIC WAVEGUIDE
Price range: $1,500.00 through $2,600.00
The Hydronic Waveguide provides a solution for radio frequency (RF) and electromagnetic interference (EMI) mitigation for shielded enclosures that requires fluid pass-through without compromising the shielded envelope. The product features a grooved-end pipe connection that can be securely attached to a shielded enclosure wall, enabling quick installation of a hydronic system and simplifying maintenance while maintaining optimal flow rates.

Understanding the Hydronic Waveguide
A Hydronic Waveguide provides shielded piping penetration, fluid lines cross the shielded enclosure boundary while shielding effectiveness is maintained.
Traditional hydronic penetrations through shielded walls use threaded or welded connections that are permanent, require specialised tools and hot work, and must be cut open again for any future maintenance access. The Hydronic Waveguide replaces this with a mechanical bolt-in connection using standard grooved-end fittings.
Purpose-built shielded enclosure hydronic connection
Engineered from scratch for shielded facility service, not a plumbing fitting adapted to the use case.
Removable, flame-free installation
Mechanical bolt-in connection means future maintenance access without cutting into the shielded envelope again.
Where the Hydronic Waveguide Is Used
Specified across facilities where fluid lines must cross an RF or EMI shielded boundary.
SCIF Piping Penetration
Fluid pass-through for ICD 705 compliant spaces where standard threaded penetrations compromise the secure envelope.
MRI Piping Penetration
Cooling water and chilled water lines entering the shielded walls of MRI suites. Avoids the disruption of welded penetrations during MRI room retrofits.
TEMPEST Penetration
Fluid lines crossing the secure envelope of TEMPEST-controlled facilities where emanation security must be maintained across every penetration.
RF Shielded Piping Penetration
RF anechoic chambers, screen rooms, and secure communications facilities where radio frequency isolation must be preserved.
EMI Shielded Plumbing Penetration
Fire protection, domestic water, and process fluid lines entering electromagnetic-shielded rooms.
RF/EMI Testing Facilities
Product certification labs and dedicated test chambers where fluid pass-through must not introduce measurement artefacts.

Not currently. In our experience, every installation of a waveguide is different and has a variety of factors that will change the length of the hardware and the type of RF gasket material required to make a tight connection. We may offer some options for gasket kits in the future.
A grooved pipe connection is a fast, reliable and flame-free mechanical joining method. It utilizes a cold formed or machined groove near the pipe ends, a rubber C-shaped gasket to seal the joint, and a bolted split-metal housing that locks into the grooves to provide structural strength. The groove dimensions machined in the Hydronic Waveguides complies with ANSI/AWWA C606 grooved joints. Manufacturers of these piping systems include, but are not limited to, Victaulic and Gruvlok.
