Packaged units – also known as coldboxes – are utilised 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 5 m by 7 m 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 harbours. The coldboxes are insulated by packing perlite in the empty spaces around the cryogenic equipment.

The self-supporting steel compartment comprises a number of components including:

  • Columns

  • Plate-fin heat exchangers

  • Pressure vessels

  • Separators

  • Interconnecting piping

  • Instrument lines for temperature and pressure measurements

  • Pressure difference and level indicators

  • Wall penetrations

  • Valves

All of our components are factory assembled and welded, which speeds up construction and set-up times on site saving delivery time and reducing cost.

All of 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 norms.
