FAQ
Q: What is included in your Cold Storage Solutions package?
Our integrated cold storage package covers three core systems: Cold Storage Panel, Cold Storage Door, Refrigeration System. We supply the full envelope and equipment as one coordinated package, or individual systems to match your scope.
Q: Which cold storage panel cores do you offer?
PIR (竹＞0.022 W/m﹞K, B1 fire-rated, best thermal performance), PUR (竹＞0.023 W/m﹞K, economical), and EPS (竹＞0.038 W/m﹞K, budget option). Panel thickness 50每200 mm, width 1,000每1,200 mm, lengths up to 12 m. Cam-lock and tongue-and-groove joint options. Stainless steel or color-coated steel skins available for food/pharma grades.
Q: What door types are available for cold storage?
Manual and electric sliding doors (single/double leaf), hinged swing doors, rapid PVC high-speed doors, free-impact traffic doors (personnel/forks), airlock/vestibule doors, and dock shelter seals. All doors feature heated frames, EPDM gaskets, and aluminum/stainless thresholds to prevent ice buildup.
Q: How do you ensure the refrigeration system matches my product?
We calculate cooling load based on: storage temperature (-60∼C to +15∼C), product type (frozen food, fresh produce, pharma, seafood), daily throughput, ambient conditions, and door opening frequency. We then size condensing units, evaporators, expansion valves, and defrost cycles accordingly. Both air-cooled and water-cooled systems available.
Q: What racking systems work best in cold storage?
Narrow-aisle racking (maximizes space at -25∼C), drive-in racking (high-density frozen storage), shuttle-car racking (automated, operator-free in deep-freeze), and push-back racking (LIFO, medium density). All racking is galvanized or powder-coated for low-temperature corrosion resistance.
Q: How do you prevent air leakage and moisture infiltration?
Continuous air barrier at panel joints using factory-applied PIR gaskets, butyl tape at all seams, EPDM door seals with heated frames, pipe/wire penetration seals with flanged escutcheons, and vapor-tight conduit fittings. We target ≒0.5 ACH natural infiltration at operating temperature.
Q: What does the electrical and control panel include?
PLC-based temperature controller with HMI touchscreen, multi-zone PID control, alarm system (high/low temp, power failure, door-open), data logging (7每30 days), remote monitoring via 4G/Wi-Fi, and UPS backup. Compatible with BMS integration (Modbus/BACnet). Panel rating IP54/IP65, anti-condensation heater included.
Q: What temperature ranges can your cold storage handle?
High-temp: 0∼C to +15∼C (fruits, vegetables, flowers). Medium-temp: -10∼C to 0∼C (chilled meat, dairy). Low-temp: -25∼C to -10∼C (frozen food). Ultra-low: -60∼C to -25∼C (tuna, vaccine, plasma). Blast freezer: -40∼C to -35∼C (IQF quick-freezing).
Q: What floor system do you recommend for cold storage?
XPS or PIR insulation (100每200 mm) + vapor barrier (Class I, ≒0.1 perm) + heated floor slab (trace heating cables) + non-slip wear surface. Floor U-value ≒0.10 W/m2﹞K. Heated threshold at doors prevents ice formation. Floor design prevents frost heave in deep-freeze rooms.
Q: Do you provide temperature monitoring and defrost control?
Yes. Multi-point PT100/RTD sensors, digital display controllers, automatic hot-gas defrost or electric defrost timed by compressor runtime, door-open duration, or evaporator coil temperature. Alarm output to siren, SMS, or remote dashboard.
Q: What are your typical lead times and export support?
Panels and doors: 2每3 weeks. Refrigeration units: 3每5 weeks. Full turnkey cold storage: 6每10 weeks. We export by sea with full documentation 〞 panel test reports (fire/thermal), refrigeration performance curves, electrical schematics, installation manuals, and remote commissioning support.
Q: What are the most common cold storage mistakes to avoid?
Undersizing refrigeration (cheap upfront, expensive forever), wrong vapor barrier placement (trapped moisture = ice inside panels), ignoring door heat (frames freeze shut), no backup power for controls, and mixing ambient air through poor sealing. Design the envelope, refrigeration, and controls as one system 〞 that's where reliability lives.
