Temperature Controlled Containers

We are at times asked to provide equipment for special applications. Some of the more interesting designs are below.

This is a chassis mounted container with a fully redundant refrigeration system. The customer wanted an easy opening door. The control systems were modified to use digital thermostats. The primary system operates in a three-degree temperature band and the secondary system comes on if temperature moves more than three degrees from set point. The container stores pharmaceuticals.

This trailer was also modified for another customer to provide redundancy with a second unit installed into the sidewall.

This also contained pharmaceuticals requiring a tight temperature band. The refrigeration systems were modified for constant run with cylinder unloading on the compressors instead of a normal on-off cycle.

The condenser fan motors were altered to cycle so that system pressure and temperature delivery would be more stable. All this resulted in a three-degree temperature band.
