These are model examples based on typical situations. Our clients’ actual reports are confidential; on request, we can show an anonymized sample report. Completed projects with figures and client letters are published as we receive our clients’ consent.
Distributor warehouse, 900 m²
| Parameter | Value |
|---|---|
| Facility | warehouse 45 × 20 m, racking up to 6 m, +15…+25 °C |
| Grid per the EEC guideline | 4 × 3 × 3 = 36 data loggers |
| Additional | two dock doors, 2 air conditioners, outdoor: 5 |
| Total | 41 data loggers, 10 min interval |
| Studies | July (8 days), January (8 days) |
Typical findings
- In summer, the upper rack levels along the south wall warm up to +24…+25 °C in the afternoon, leaving less than 1 °C of margin to the limit.
- In winter, the first two rack locations by the loading dock doors drop below +15 °C during peak dispatch.
- The monitoring sensor mounted on a column in the center at a height of 1.5 m does not cover any of the problem zones.
Solutions
- the rack locations by the doors are removed from the storage area and assigned to dispatch, for staging goods before shipment;
- two monitoring sensors are relocated: to the top level by the south wall and to the bottom level by the doors;
- an air curtain is added, along with a procedure for closing the doors between trucks;
- the critical summer season is re-studied a year later.
Cold room, +2…+8 °C
| Parameter | Value |
|---|---|
| Facility | cold room 12 × 8 × 3 m, two evaporators, 2.6 m racking |
| Grid | 3 × 2 × 2 = 12 positions |
| Additional | door, 2 evaporators, outdoor: 4 |
| Tests | 48 h steady state, 3 door openings of 60 s each, power failure |
| Interval | 2 min |
Typical findings
- The top shelf opposite the evaporator drops to +1.5…+2 °C after defrost, creating a risk of freezing.
- By the door, the temperature stays at +8.5 °C for 4 minutes after an opening; recovery takes 11 minutes.
- During a power failure, the first position exceeds +8 °C after 47 minutes.
Solutions
- the top shelf opposite the evaporator is excluded for freeze-sensitive products;
- a deflector screen is installed; a repeat 24-hour study confirmed +2.6 °C at the former cold spot;
- a 10-minute delay is set for the high-temperature alarm, based on the recovery data;
- emergency plan: 45 minutes to move the products.
−80 °C freezer
| Parameter | Value |
|---|---|
| Facility | upright ultra-low temperature freezer, 5 shelves |
| Positions | 9 external Pt1000 probes, loggers outside the freezer |
| Tests | 24 h steady state, 60 s door opening, power failure |
Typical findings and solutions
- The top shelf by the door is 4–6 °C warmer than the center; after an opening, recovery to −70 °C takes about 25 minutes, so the most valuable samples are moved to the middle shelves.
- During a power failure, the time to reach −60 °C is about 4 hours when fully loaded and considerably shorter when half loaded, so the procedure now requires a backup freezer to be kept available.
Refrigerated semi-trailer
| Parameter | Value |
|---|---|
| Facility | 13.6 m semi-trailer, +2…+8 °C, 33 pallets |
| Positions | 13 in the cargo space + 1 outside, 1 min interval |
| Scenarios | pre-cooling, loaded trailer for 12 h, 6 stops with door openings, winter with −25 °C outside |
Typical findings and solutions
- Pallets placed tight against the front wall by the refrigeration unit are hit by the cold air stream and drop to +1.8 °C, so a clearance gap is introduced and the top row next to the unit is not used.
- In winter, the bottom row by the rear doors drops to +2 °C during long stops, so the heating mode is enabled and door-opening time is limited.
- The monitoring sensor is moved out of the supply air stream into the rear third of the trailer.
Frequently asked questions
Can I get a sample report?
Yes, on request we will provide an anonymized sample mapping report.
How long does a warehouse project take?
For one season, usually 3–4 weeks from receiving the floor plan to delivering the report. The second season is scheduled for the opposite time of year.
