The Safe-t-FLEX radiant ceiling heating system is not recommended for warehouses or other areas where very high ventilation rates can be present. The solution for such areas may be the use of ceiling mounted Safe-t-CASSETTEs. Safe-t-CASSETTE heating cassettes are a development of traditional radiant ceiling heating. The radiant heating element is sealed in a steel casing and finished with white textured or satin finish paint. Applications: Safe-t-CASSETTES can be used in difficult to heat areas, agricultural kennels, stables and farm buildings, commercial offices, shops, and store areas, industrial buildings and hospitals. It provides localised comfort levels.
