Xnair industrial cold storage project overview - food processing, logistics, biopharma, and chemical explosion-proof cold rooms

Food cold storage project by Xnair - refrigerated processing room with stainless steel interior

Food Cold Storage Projects

Temperature-controlled facilities for meat, seafood, dairy, and frozen produce processing. Each project integrates rapid chill tunnels, blast freezers reaching -40°C core product temperature within 4 hours, and long-term frozen storage at -18°C to -25°C. Panels use food-grade stainless steel interior liners with rounded internal corners to eliminate bacterial harborage points, meeting HACCP facility design guidelines.

Range: -40°C ~ +15°C Panel: 100–200mm PU HACCP-ready

Logistics cold storage warehouse project by Xnair - high-bay racking with dock leveler integration

Logistics & Warehousing Cold Storage

Large-volume refrigerated warehouses designed for third-party logistics providers and distribution centers. Clear internal heights up to 12 meters accommodate high-bay pallet racking systems. Rapid-close insulated dock doors with inflatable dock shelters maintain temperature integrity during cross-docking operations. Multi-zone configurations allow simultaneous -25°C frozen and +2°C chilled storage within a single building envelope, minimizing footprint and operational cost.

Range: -25°C ~ +15°C Height: up to 12m Multi-zone

Biopharmaceutical Cold Storage

GMP-compliant cold rooms for vaccine intermediates, biologics, and temperature-sensitive active pharmaceutical ingredients. Temperature uniformity is maintained at ±0.5°C across the entire storage volume through computational fluid dynamics-optimized airflow. Redundant N+1 refrigeration circuits with automatic failover ensure 24/7 temperature stability. Full IQ/OQ documentation packages support regulatory submissions. Monitoring systems log data at 15-second intervals with audit-trail integrity.

Range: +2°C ~ +8°C Uniformity: ±0.5°C GMP / GDP

Chemical Explosion-Proof Cold Storage

ATEX-compliant refrigerated enclosures for volatile solvent storage, hydrocarbon sample preservation, and hazardous material containment. All electrical components—compressors, evaporator fans, lighting, and control panels—carry Ex II 2G T4 certification for Zone 1 and Zone 2 classified areas. Panel cores use B1-rated flame-retardant PIR with galvanized steel facings. Spark-free interior construction eliminates ignition sources. Temperature ranges from -20°C to +10°C depending on stored chemical profiles.

Range: -20°C ~ +10°C ATEX Ex II 2G T4 B1 PIR panels

Frequently Asked Questions About Xnair Cold Storage Projects

What types of cold storage projects does Xnair specialize in?

Xnair engineers cold storage projects across four core sectors: food processing cold rooms, logistics and warehousing refrigerated facilities, biopharmaceutical GMP-compliant cold storage, and chemical explosion-proof refrigerated enclosures. Each project is custom-designed to the specific temperature range, humidity control, and regulatory requirements of the application.

What temperature ranges can Xnair cold storage solutions achieve?

Xnair cold storage projects span from ultra-low -40°C blast freezers for food processing to tightly controlled +2°C to +8°C biopharma cold rooms. Logistics warehousing typically operates between -25°C and +15°C depending on stored goods. Each project is engineered with the appropriate compressor capacity, evaporator sizing, and insulation thickness to maintain the specified range under full load conditions.

Does Xnair provide explosion-proof cold storage for chemical facilities?

Yes. Xnair manufactures explosion-proof cold storage solutions with ATEX-compliant components, including flameproof compressors, intrinsically safe electrical enclosures, and spark-free interior fittings. Panel cores use B1-rated flame-retardant PIR with steel facings. These facilities are designed for storing volatile solvents, hydrocarbon samples, and other hazardous materials requiring refrigerated containment.

What certifications do Xnair cold storage projects comply with?

Xnair cold storage projects are manufactured under ISO 9001 quality management and carry CE marking for the European market. Biopharma projects are designed to GMP and GDP guidelines with full IQ/OQ documentation packages available. Explosion-proof units meet ATEX directive 2014/34/EU requirements. All electrical components comply with IEC 60335 safety standards.

Quality Assurance & Industrial Certifications

Every Xnair cold storage project undergoes a rigorous factory acceptance testing protocol before shipment. This includes:

Refrigeration performance test: Compressor pull-down rate, evaporator capacity verification, and full-load temperature mapping across 12+ sensor points for a minimum of 48 continuous hours.
Insulation integrity check: Thermal imaging scan of all panel joints and corner connections to identify any thermal bridging. Panel thickness is verified against design specifications with calibrated ultrasonic measurement.
Electrical safety verification: Insulation resistance testing at 500V DC, earth continuity measurement, and functional validation of all safety interlocks and emergency stop circuits per IEC 60335.
Explosion-proof certification audit (for ATEX units): Third-party notified body inspection of flameproof enclosures, cable gland integrity, and spark-free component verification prior to issuing the declaration of conformity.

Xnair cold storage projects are manufactured in compliance with international standards including CE marking (EU), ISO 9001:2015 quality management, and ISO 14001 environmental management. Biopharma-grade facilities are aligned with WHO GDP and EU GMP Annex 15 guidelines. All panel materials carry third-party fire performance test reports.
