Cold Chain

Working conditions

Cold-chain sites combine freezer rooms, chilled dock areas and temperature-controlled distribution. Trucks move between zones, so condensation, ice on the floor and repeated entry into the freezer shape the specification. Doors and curtains slow every cycle, and the truck may sit idle in the cold between tasks.

The site's actual temperature range has to be measured before a battery configuration is fixed. FENGSONG publishes no fixed low-temperature rating for cold-store operation: the configuration is confirmed against the on-site temperature and the charging routine. For high-temperature sites, the lithium BMS is rated for ambient conditions up to 45 °C, and summer sites are commonly quoted in the 35–45 °C band.

Recommended capacity and models

The 1.5–4.0 t electric counterbalance range is the usual starting point, on 76.8 V (80 V platform) LiFePO4 packs in 125, 150 and 202 Ah ratings. Lithium suits multi-shift cold stores because it can be opportunity-charged without a battery change; lead-acid remains an option where a heated charging room and a swap routine already exist.

• Sealed electrical components and a BMS protected against dust and moisture
• Charging planned outside the freezer, in a dry area
• Mast and fork configuration matched to racking height — 3,000 mm standard, 4,500 / 6,000 mm on request
• FS-CPD20 and FS-CPD25 for 2.0–2.5 t pallet work in chilled distribution

What to confirm before ordering

• Measured temperature in each zone the truck will enter — no low-temperature figure is assumed
• Where the truck charges, and whether it can stay in a dry area between shifts
• Floor condition and any ice or water on ramps
• Door widths, racking height and pallet weights

Send the zone temperatures and the shift pattern with the inquiry; the export team will confirm the sealing and battery configuration before the order is scheduled — lead time 30–45 working days after deposit (standard models).
