ExoVent™ Cold – Heat & Smoke Ventilators for Cold Storage
The R&S High-R Cold Storage Smoke Vent is for cold storage buildings that require smoke ventilation. Product features 6″ R-39 insulation and a complete thermally-broken design that eliminates interior condensation. Operates with (2) UL listed fusible links which melt at preset temperatures and opens the lids. Optional McCabe re-settable links operate the same way but also include electronic activation. Includes high-performance gas springs and a custom latching system rated for a 90 PSF uplift. Interior and exterior release with hold-open arms that lock the vent in the open position. Lids open against a 10 PSF live load.
The cold storage smoke hatch includes curbs that fit any metal building roof panel. Self-flashing caps are also available for conventional roofs. Vent lids are aluminum with 6″ insulation. Curb comes standard in aluminum with a cost-saving galvanized steel option. Mill finish comes standard but may include a powder coat or Kynar custom color finish as specified. Various sizes are available.
