Coldrooms
Technician
Sizing, install, defrost and the faults that keep them running — done properly.
Coldrooms are where a lot of techs earn their keep and where a lot of avoidable failures happen. Selection, install, defrost and load all matter.
Defrost
- Off-cycle, electric, hot gas — when to use each
- Defrost termination and drain heat tracing
Common faults
- Ice build-up and poor defrost
- Drain freezing and water damage
- Door loads and infiltration
