1 Hour Fire Rated Drum Store - DPU16-4FR To Hold 16 Drums Or 4 IBCS A rolled hollow welded frame creates a strong structure for this fire rated drum store. The walls, two hinged-doors and roof have been in-filled with Rockwool Firebatt insulation and covered with sheet steel to provide 1 hour fire rating. A fully seam welded sump, with profiled rib straighteners and galvanised support channels, creates a bunded area in case of a spill, and base plinths eliminate contact with the ground. High and low level vents fitted with intumescent elements allow air to circulate, however in the event of a fire, these elements will expand and seal the vents, this takes place at temperatures above 150C. This unit can hold up to sixteen 205ltr drums (4 pallet locations) or four 1000ltr IBCs on two levels. The sump fully complies with all the UK regulations relating to sump capacities.
