PPS Transit Sleeves

GREENTECH HEATSHIELD PPS Transit Sleeves are designed to restrict the spread of fire and smoke from one compartment to another where network / data cables and electrical cables penetrate through fire rated separating walls and floors, and allow for the removal and re-fitting of cables while maintaining the integrity of the seal.

GREENTECH HEATSHIELD PPS Transit Sleeves are 30cm long plastic cylinders which contain a heat reactive intumescent liner and have 2 flame retardant cellular foam end plugs which are removable to allow easy retrofitting of new cables. PPS Transit Sleeves are a versatile and cost effective solution where cable changes or regular modifications occur.

How do HEATSHIELD PPS Transit Sleeves work?

When exposed to elevated temperatures of a fire situation, the intumescent material contained in the PPS Transit Sleeve activates and expands, to fill and seal the sleeve and gaps and voids around degrading cables. Once fully activated the intumescent material forms a plug which prevents the spread of fire and hot gases from one compartment to another. The foam end plugs can help to reduce cold smoke transmission.
