The bread and butter — done properly
Coolrooms & Freezer Rooms
Coolrooms and freezer rooms are where a lot of refrigeration techs earn their keep — and where a lot of avoidable failures happen. We cover selection, install, commissioning, defrost and the faults that keep them running.
Sizing and selection basics
- Load, product temperature and door loads.
- Why undersized rooms never hold temp.
Install and pipework
- Line sizing, traps and risers.
- Insulation and vapour barriers.
- Brazing and pipework that doesn't leak or oil-log.
Defrost systems
- Off-cycle, electric and hot gas — when to use each.
- Defrost termination and drain heat tracing.
Common faults
- Ice build-up, poor temp, defrost issues.
- Drain freezing and water damage.
What you'll get
- Install and commission coolrooms properly
- Diagnose the common coolroom faults fast
- Set defrost so it actually works
