PORTISO

What PORTISO does

PORTISO is a product brand within the Coldkit group, focused on loading dock levelers and bumpers, while the broader Coldkit Doors portfolio covers industrial and isothermal doors for cold storage, logistics, and agro-food applications. The company manufactures a comprehensive range of products including hermetic sliding and pivoting doors (industrial, commercial, and fire-resistant), rapid roll-up doors in aluminum and stainless steel for the agri-food sector, multi-compartment cold storage units (Multicool), sectional doors, inflatable and retractable loading dock shelters, hydraulic platforms, vertical dock barriers, and shelving systems in multiple depths. Underlying technology emphasizes thermal insulation, anti-corrosive finishes, self-supporting structures for rapid deployment, and compliance with European safety standards, supported by an R&D function focused on energy efficiency and product optimization.

The company operates five manufacturing facilities across Portugal, Spain, France, and the United Kingdom with annual production capacity exceeding 40,000 door units, positioning it as one of the larger European producers of industrial and insulated doors. Coldkit sells quote-based with no public pricing; revenue is generated through direct enterprise sales supported by customer consultation, technical advisory, project sizing, and installation training. Primary customers are enterprise buyers across the agro-food industry (food processing, meat processing, dairy, bakery), logistics centers and warehouses, and retail supermarket chains — with named installations at S. Miguel (Matadouro) and Panidor. Marketing is largely organic social (Facebook, LinkedIn, Instagram) combined with direct consultation.

Founded in 1985 and headquartered in Madrid in the firmographic record (with the Coldkit legal entity domiciled in Portugal), the company is privately held with no disclosed funding, M&A, or ownership structure beyond an apparent brand affiliation with the Purever group. Coldkit reports significant growth in international markets and a stated commitment to R&D, certifications, and compliance to meet European regulatory and energy-efficiency requirements.
