Solar Cold - Description

Solar Cold

The new developed 20-ft-cold-storage container ist designed for cold-storage of varying food-stuffs with regard to extreme ambient conditions, e.g. for hot and rich of sunshine areas with different conditions of relative humidity, and with an assured inside temperature level over approx. five consecutive days under very low solar radiation rates only.

Main features

  • stand-alone exclusively PV-supplied cold-storage container with redundant designed special adapted cooling and energy supply systems
  • transportable by lorry, train, and, if possible, helicopter
  • integrated and hinged for transportation besides wall and roof PV-areas
  • total outer dimensions similar to 20-ft standard container
  • servo supported PV-area installation mode for uncomplicated and short putting into service (approx. 2 hours for one hand)
  • 26 m³  cooling room volume for food-stuff cold-storage
  • down to a level of zero degrees Celsius (+ 32 °F) inner room temperatures
  • max. ambient temperature + 50 °C (+ 122 °F)
  • special adapted control modes
  • ready for operation container design, practically no maintenance need
  • maintenance-free battery and cold-storage systems
  • high efficiency solar modules
  • hermetically sealed solar batteries
  • sealed cold-storage system
  • CFC-free regrigerant
  • easy to clean stainless-steel walls
  • high efficient wall isolation
  • burglar proof over all system design
