Sliding insulated door (positive T°) – SP400

The SP400 sliding insulated door was developed to offer a solid, durable, top-quality door that could be used just as easily for small cold rooms as for refrigerated warehouses with large openings to allow the passage of forklift.

An insulated door suitable for all cold rooms.

With its 1.5 mm thick stainless casing and edging profile and its enhanced insulated core, it helps maintain the hygiene and food safety conditions necessary in insulated chambers.

The SP400 insulated door is custom made to your measurements and supplied ready to install.
