Description FyreCOLLAR mixed service fire collar is designed to provide compliant fire protection for HVAC&R service penetrations, allowing multiple services to pass through a single opening while maintaining fire resistance. It enables pair coil, cables, insulated pipes, and drain lines to be treated together in one penetration, delivering a clean, efficient, and space-saving fire stopping solution. HVAC&R services require thermal insulation to maintain performance, but these materials can burn away under fire conditions, making fire stopping more complex than standard metal pipe penetrations. FyreCOLLAR addresses this by: Accommodating insulated pipe systems Sealing penetrations with multiple service types Maintaining fire compartmentation in complex installations FyreCOLLAR mixed service fire collars are lined with a high-performance intumescent material that expands when exposed to heat. In a fire event, the system: Expands to close gaps around services Compensates for burnt or melted insulation (lagging) Forms a tight seal around copper pipes and cables Compresses insulation to maintain penetration integrity This allows multiple HVAC&R services to be grouped within a single compliant penetration system.
