The SNIF^® P-Cartridge is a refractory furnace lining that is easily replaced. When the furnace refractory needs to be changed, the spent cartridge is lifted by using a specially designed spreader bar and a crane. After the used P-Cartridge is removed, a new lining can be installed within a few hours.

The one piece refractory lining is manufactured by Pyrotek's SNIF division under controlled conditions in our pre-cast shapes manufacturing facility. The design using high temperature refractory and multiple layers of insulation provides maximum service life and superior insulation.
