Quick answers
What this page covers
A stable cold chain depends on more than the refrigeration system. Cargo space, insulation, door openings, airflow, goods and workflow must work together.
Door openings are a key factor
Frequent stops allow warm outside air into the cargo compartment. Depending on the goods and target temperature, this can significantly affect temperature recovery time.
- Keep doors open for as little time as possible.
- Arrange goods by route to reduce time spent searching.
- Consider strip curtains or partition solutions for the application.
- Record temperature history for sensitive goods.
Stationary refrigeration and route planning
Stationary refrigeration can stabilise temperature control when vehicles stand for longer, are loaded frequently or carry particularly sensitive goods.
- Clearly specify stationary periods and loading windows before design.
- Assess 230-V stationary refrigeration or electric solutions for each project.
- Assess the temperature range, goods and daily door openings together.

Frequently asked questions
Frequently asked questions on this topic
How do door openings affect the cold chain?
Every door opening brings warm outside air into the cargo compartment. Frequent or prolonged openings increase recovery time and can impair temperature stability.
When is a strip curtain useful?
A strip curtain can help with frequent loading and unloading when air exchange needs reducing. Suitability depends on the goods, cargo space, access and cleaning requirements.
When is stationary refrigeration worthwhile?
Stationary refrigeration is especially useful for long stops, sensitive goods, frequent loading and unloading, or when temperature needs to remain stable independently of driving.
