The Xtralis Refrigerated Storage Sampling Kit provides a standardised method of smoke sampling for Refrigerated Storage facilities in a considerably improved manner allowing simplified installation with reduced maintenance, thus promoting more reliable and hassle-free operation. The Xtralis Refrigerated Storage Sampling Kit has been designed to replace standard cone-shaped sampling nozzles installed at the ceiling in existing or new Refrigerated Storage facilities. This kit can be installed in the entire facility or combined with standard sampling points if required. The aim here is to reduce direct ice blockage of the sampling points hence this kit is recommended for installation in areas where higher humidity is likely to occur as a result of vehicle and pedestrian traffic (e.g. areas close to doorways or perimeter of the facility). This kit is treated as a stand.
