Technical Field
The following description relates to container (container) refrigeration units, and more particularly to curtain (shade) track seal adapters.
Background
Curtains are commonly used to seal the back doors of container refrigeration units that use a Controlled Atmosphere (CA) air quality system. The curtain is typically installed by inserting a flat plastic band over the curtain and into a curtain track formed in the container wall. However, this process can be tedious and inconsistent, and such verbosity and inconsistency can lead to variability in the rear door seal. For example, if the process is not carefully performed, the curtain may be damaged, and such damage may cause air leaks that would prevent the CA air quality system from operating properly.
