The Kaiser HWD 90 is a German-manufactured fire protection cavity wall box designed for electrical accessories installed within lightweight wall constructions.

Incorporating Kaiser AFS (Automatic Fire Stop) intumescent technology, the HWD 90 is designed to react to fire and heat by expanding and closing the installation opening. The system is supported by European fire testing, approvals and classifications, including applications within fire-rated wall systems and timber wall constructions.

The HWD 90 is suitable for European-format electrical accessories, building automation devices, control interfaces and specialty installations where larger-format mounting systems may be required.

European Testing & Approvals

The HWD 90 is supported by European fire testing and approvals for application within:

Fire-rated wall systems
Installation shafts and installation ducts
Timber frame and timber panel wall constructions
Acoustic wall systems

Supporting technical documentation, fire test reports, ETA approvals and DIBt approvals are available on request.

Australian Projects

The suitability of the HWD 90 for use within Australian projects should be assessed having regard to:

Wall construction type
Required FRL
Installation methodology
Applicable project requirements
Fire engineering and certification requirements

Black Cat Control Systems can provide available manufacturer technical documentation and supporting test evidence. Assessment of the suitability of the complete wall system remains the responsibility of the project design team, fire engineer and certifier.
