40’ HC Reefer TK Mag+ Container to meet your needs. With its longer dimensions and high cube construction, you can enjoy the benefits of using containers this size and reefer machines only by Thermo King. This container relies on Thermo King’s Magnum Plus reefer machine, which can help you regulate the cargo’s temperature between -40°C (-40°F) and +40°C (104°F) in an ambient environment. With this ability, your temperature-sensitive cargo from sashimi-grade salmon to fragile pharmaceuticals will not degrade from exposure to unregulated temperature.
