Egis RailGlide M90

In meat plants the product travels overhead on rails — and every doorway the rail crosses is a sealing problem. Cut a slot for the rail and cold pours out; leave the door open and the cold chain fails. The RailGlide M90 is a sliding cold-room door with a rail cut-out: a shaped, gasketed slot in the upper leaf through which the meat rail passes, so carcasses glide through while the doorway stays thermally sealed around them.

The cut-out is lined with replaceable brush and blade seals that hug the rail and its hangers as they pass, wiping the seal line with every carcass. The leaf carries 90 mm PIR insulation for chiller duty with a heated perimeter gasket, and the full sliding format keeps the wide openings meat plants need for rail curves and switches — clear openings up to 3000 mm wide and 3000 mm high.

Egis engineers the M90 to the plant's actual rail profile and height — send the rail section and the cut-out is built to fit it. Stainless cladding and washdown-rated sliding gear handle the daily hosedown regime of meat processing, and the brush and blade seals are replaceable wear parts, not a service call.

Sealing around a rail is a moving-target problem: the rail is fixed, but hangers and carcasses pass through the seal line continuously. A rigid seal would be destroyed in days. The M90 uses a brush seal backed by a flexible blade: the brush bristles part around each hanger and close behind it, while the blade maintains contact with the rail itself. Together they hold the thermal line while the product keeps moving — and both are replaceable wear parts, because a seal that cannot be replaced is a seal that will be neglected.

The rest of the leaf is a conventional high-performance chiller door: 90 mm PIR insulation for the +12 to -5 C band, heated perimeter gasket for the seal line, and stainless cladding over washdown-rated sliding gear. The cut-out is engineered into the leaf's insulation continuity so the slot does not become a cold bridge through the 90 mm core.
