FyreCHOKE mixed service fire collars

The FyreCHOKE mixed service collar is designed to treat multiple sets of pair coil plus their cables, insulated pipes and drain lines, all through one penetration, thereby making HVAC&R penetrations fast, clean and easy. HVAC&R pipes require thermal insulation to maintain the thermal efficiencies required to run air-conditioning and refrigeration services. However, these thermal insulation materials can quickly burn away in the high temperatures of an AS1530.4 fire test, which makes passive fire penetrations of HVAC&R services more complicated when compared to bare metal pipe penetrations, for example.

FyreCHOKE mixed service fire collars are lined with an intumescent material that expands with the heat of a fire to close off the gaps around services inside a fire collar, filling up the spaces left by the burning/melted thermal lagging to tightly seal around the copper pipes. The intumescent material is strong enough to crush off pair coil insulation and form a tight seal around the cables, so all of these services can be bundled together to make passive fire protection of HVAC&R services fast and easy.
