Incoming goods add heat and may raise room-air temperature temporarily.
In short: check delivery temperature, load in manageable batches and keep the evaporator airflow clear.
Record non-conforming deliveries before placing them with accepted stock. Warm cooked food or production output may need a blast chiller; a storage room is not automatically designed to cool it safely within a set time.
After a large delivery, watch temperature recovery and product temperature according to HACCP. If recovery is slower than normal, check doors, load arrangement and refrigeration operation.
Why loading is a risk
A large or warm load can lift the interior temperature by several degrees and push it temporarily out of range. The refrigeration unit is sized for the steady-state heat load plus normal door traffic, not for a single warm pallet dumped in at once.
Best practice for loading
- Pre-cool where possible. Product that arrives already chilled puts far less strain on the system than warm goods.
- Load in stages. Split a big delivery into batches and let the room partially recover between them.
- Do not overload. Respect the room's designed capacity; an over-packed room cannot circulate air well enough to cool it.
- Place warm items centrally — not pressed against walls and not directly under the evaporator, where they would disrupt the discharge airflow.
- Check the temperature after loading and watch the recovery time. If recovery takes noticeably longer than usual, investigate before assuming it is fine.
Why staged loading matters: Staging keeps the room inside its food-safe window while the compressor catches up — and avoids the long, hard run cycle that wears equipment and spikes the energy bill.
