Cryogenic Distillation Coldboxes

Delivering Cold Boxes in sizes of up to 5m X 7m and up to 40m long

Packaged units – also known as Coldboxes – are utilized in a wide range of applications for the treatment of cryogenic fluids and gases, including air separation plants, gas separation and liquefaction plants, chemical and petrochemical plants. We deliver a range of Coldboxes in sizes of up to 5m X 7m and up to 40 m long. Boxes that are too large for preassembly and road transport are assembled and tested directly on site or at Linde Engineering workshops located near harbors. The coldboxes are insulated by packing perlite in the empty spaces around the cryogenic equipment.

All our components are factory assembled and welded, which speeds up construction and set-up times on site saving delivery time and reducing cost. All our packaged units are designed according to client specifications. They also meet requisite national and international standards and regulations, such as AD-2000, the Pressure Equipment Directive 97/23/EG (PED, CE-marking), ASME, British Standards, and DIN or EN.
