Abstract: A refrigerant bunker comprises a refrigerant covering comprising a first thermally insulating material configured to enclose a solid refrigerant and an outer container comprising a container body and a container cover. The container body comprising an outer surface, an inner surface defining a partially enclosed space configured to accept the solid refrigerant and an opening for accessing the partially enclosed space. The container cover is configured for covering the container opening. The container body comprises a second thermally insulating material. A plurality of spacers protrude from the inner surface of the outer container in the partially enclosed space. The plurality of spacers are positioned to have gas fillable gaps between the spacers. Coolers employing the refrigerant bunker are also disclosed.

Abstract: An article of manufacture for use as an insulated overhead door that is designed to roll open and closed in tracks, with a sheet of thermoplasitc material that acts as the outer door membrane and barrier to entry, a sheet of insulating material that acts as a base insulating barrier adhered to the thermoplastic membrane.

Abstract: A pneumatic door system and a method of using the same are disclosed herein. According to one embodiment, a trailer may include a seamless main door and at least one side door. The doors may be configured to be locked shut with a system of pneumatic locks. The main door may be configured to open and close as controlled by pneumatic pressure applied to a door cylinder. The pneumatic system may be configured to be controlled by an interior control box. The pneumatic system may be configured to operate off of pneumatic pressure in an auxiliary air tank, the pressure being protected by a series of one-way check valves. The pneumatic system may also be configured to operate wirelessly using RFID or Bluetooth technology, among other things, to secure the cargo and facilitate ingress and egress to the trailer.

Abstract: A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow a release assembly to move out of the track. The release assembly includes a biasing mechanism that allows the assembly to flex and ride out of the track when the door is impacted.

The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow a release assembly to move up the sidewall and out of the tracks, and a tensioned or spring loaded release assembly that allows the assembly to flex enough to ride up the sidewall and out of the tracks when the door is impacted.

Abstract: A system for allowing a loading dock door to release from guide tracks. The dock door includes wheel-and-axle assemblies which are mounted to the door and which include wheels biased towards a position in the tracks. At least one of the tracks has a cross sectional profile which enables the wheels disposed in the one of the tracks to move out of the one of the tracks when the door is struck with sufficient force.

Abstract: A flexible door panel cold storage door system incorporates a flexible movable door panel having an internal support frame assembly and the door panel has a plurality of gasket sections removably attached to a cold space surface of a door panel jacket with each gasket section having at least one ferrous gasket target and the gasket sections are aligned and cooperate with a plurality of electromagnets that are mounted in a doorframe assembly when the door panel is in a closed position. The electromagnets are mounted in wells in the doorframe assembly and are powered on when the door panel is in the closed position and the wells are interconnected by a ventilation channel that conducts air heated by operation of the electromagnets through the ventilation channel and into and through a bottom sweep assembly of the door panel in a closed loop.
