An adaptive commercial refrigeration line for Haglund Industri

Founded in the 1860s, Haglund Industri has remained in the same location for five generations. Built on a principle of listening closely to customers and combining responsiveness with skilled craftsmanship, the company is now Sweden’s leading supplier of refrigeration and freezer units for restaurants and commercial kitchens, recognized for high quality and the ability to deliver fully customized solutions. Today, the company operates a modern, state-of-the-art production facility, uniting traditional knowledge with technological innovation and setting the standard in modern commercial refrigeration manufacturing.

The central challenge for this project was creating a production line that could reliably handle a high mix of cabinet models without sacrificing productivity. Haglund Industri manufactures hundreds of different refrigerator and freezer cabinet styles, ranging from large vertical wine storage units to horizontal cooling drawers. These products vary significantly in size, from very small under counters to large rooms.

Due to the nature of their customized products, the production volumes call for frequent changeovers between models. Haglund Industri have with the new line the ability to produce fully in a one-piece flow meaning that the tool and size of the machine can be changed between each produced unit and a unique flexible solution to fulfill customers’ needs in flexibility and short lead time.

In designing this plant, we gave priority and special attention to creating a fixture that can automatically adjust between Haglund’s various models. The objective of this fixture was to avoid time losses associated with frequent size changes while maintaining consistent output levels. The target was to maintain a productivity level of 7-8 completed cabinets per hour, or about 60 cabinets per day.

We provided Haglund Industri with a complete turnkey plant for manufacturing their products, including loading stations — where their customized products are still prepared by hand — preheating ovens, a double shuttle table, automatically adjusting fixture, automatic mixing head carrier, and an unloading station. With the future in mind, this plant was designed to allow for a potential expansion.

The premixing station for the expansion agent (pentane), the polyurethane dosing unit for injecting the insulating material into the cabinets, as well as the heating unit and chillers for temperature control are constructed on a mezzanine above the cabinet line. This allows plenty of space for the operators to access and conduct maintenance or cleaning without having to enter the plant itself.
