Two configurations to fit your container
Choose between a ready-to-install Monoblock configuration and a flexible Split System, depending on your container structure, equipment layout and installation requirements.
Monoblock configuration
Ready to install Solution
The outdoor unit and evaporator are supplied as a complete, pre-connected and refrigerant-charged package, designed for compact integration into the container structure.
Benefits:
- Reduced on-site installation work
- Compact, space-saving integration
- Factory-completed refrigerant connections
Split System configuration
Flexible component placement
The outdoor unit and evaporator are supplied separately, allowing flexible positioning according to the container layout and cooling requirements.
Benefits
- Flexible placement of components
- Adaptable to different container layouts
- On-site refrigerant piping and charging
EU co-funded development
The development of Lumikko’s Military Container Cooling Unit has been co-funded by the European Union.

Flexible installation for different container designs
Designed to accommodate different container structures while preserving valuable interior space for personnel and equipment.
Outdoor unit installations
Recessed installation
For corrugated container walls
The outdoor unit is recessed into the container wall, allowing compact integration into the container structure.
Surface-mounted installation
For flat exterior walls
The outdoor unit is mounted onto the exterior wall, providing a practical installation option for special-purpose containers.
Indoor evaporator installation
Ceiling-mounted evaporator
Wall-mounted evaporator
Installed directly behind the outdoor unit, with an adjustable mounting plate to accommodate different installation heights.
Engineered to fit your application
Every container application has unique structural, electrical and operational requirements. Lumikko works closely with customers to adapt the cooling system to their specific needs.
System configurations can be tailored to accommodate different container layouts, electrical interfaces, air distribution needs and control requirements.
For applications requiring higher cooling capacities, Lumikko can develop solutions with increased performance and appropriately sized components.

Additional options
Lumikko is developing additional configurations for specialised container applications, including an ATEX-related solution for environments where explosive atmospheres may occur and an integrated heating option for cold-weather operation.
Dimensions & integration requirements
Outdoor unit dimensions
The outdoor unit measures 590 × 920 × 300 mm and can be recessed into the container wall to minimise external projection. If the container’s front-wall structure provides at least 300 mm of available installation depth, a separate recess may not be required.


Indoor evaporator dimensions
The indoor evaporator measures 575 × 512 × 211 mm and can be mounted on the ceiling or wall, depending on the selected system configuration. It can also be supplied pre-connected to the outdoor unit as part of the Monoblock configuration.
Dimensions shown are for the standard cooling configuration. Dimensions may vary for customised systems and future heating options.
