Buildgram cold storage systems feature a modular, energy‑efficient integrated structure designed for stable, long‑term operation across -45℃ to +50℃.

• Enclosure Body: Prefabricated PU/PIR insulated sandwich panels; steel-framed assembled structure; excellent thermal insulation, airtightness, and structural stability.
• Refrigeration System: Single‑stage, two‑stage, or cascade refrigeration units to match high, medium, low, and ultra‑low temperature requirements.
• Cooling System: Air-cooled, water-cooled, or evaporative cooling for efficient heat dissipation and stable performance.
• Control System: Intelligent temperature & humidity control, automatic defrost, safety interlocks, and real-time monitoring.
• Auxiliary Systems: Cold room doors, air coolers, electrical cabinets, lighting, safety escape, and maintenance fittings.

• Temperature & Humidity Instability: Precise control minimizes spoilage and quality loss of perishables.
• High Energy Consumption: High‑density insulation + optimized refrigeration reduce power usage by 30%+.
• Cold Air Leakage & Condensation: Airtight panels, multi‑layer seals, and thermal‑break design eliminate frost and leakage.
• Hygiene & Compliance Risks: Food‑grade, easy‑clean materials meet GMP, FDA, and international cold chain standards.
• Slow Installation & Poor Scalability: Modular design enables fast on‑site assembly and future expansion.
• Safety Hazards: Emergency escape, anti‑pinch, anti‑freeze, and overload protection for personnel and equipment.

• Food Processing & Storage: Meat, seafood, dairy, prepared foods, frozen products.
• Fruit & Vegetable Preservation: CA cold rooms for long‑term fresh keeping.
• Pharmaceutical & Bio‑storage: Vaccines, reagents, blood products, GMP‑compliant cold chain.
• Cold Chain Logistics & Warehouses: Distribution centers, transit hubs, cross‑docking facilities.
• Supermarkets & Retail: Backroom cold storage, fresh produce sections.
• Industrial & Special Use: Chemical low‑temp storage, floral preservation, seed banking.

• Customized Design: Tailored dimensions, temperature levels, door types, and configurations based on site and demand.
• One‑Stop Turnkey Solution: Design → production → delivery → installation → commissioning → acceptance.
• Professional Installation: Certified technical team for standardized, efficient on‑site assembly.
• Intelligent Control: Auto temperature control, defrost, alarm, and remote monitoring.
• After‑Sales & Maintenance: Quick response, spare parts supply, routine inspection, and long‑term service.
• Global Export Support: Complete documentation, packaging, shipping, and overseas technical guidance.

Q1: What temperature ranges can Buildgram cold rooms support?

A: We cover +5℃ ~ -45℃:

• High‑temp: 0℃ ~ +5℃ (fruits, vegetables)
• Medium‑temp: -10℃ ~ -5℃ (chilled food)
• Low‑temp: -20℃ ~ -10℃ (frozen food)
• Ultra‑low: ≤ -25℃ (seafood, frozen storage)

Q2: What materials are used for cold room panels?

A: Standard panels use PU/PIR high‑density insulation core with 304/316 stainless steel, color-coated steel, or FRP faces. Features: low thermal conductivity, fire‑resistant, moisture‑proof, easy to clean.

Q3: What types of cold room doors do you provide?

A: Electric sliding, manual sliding, hinged, half‑buried, fully buried, free‑swing, and clean doors. All with EPDM seals, heating anti‑freeze, and safety escape devices.

Q4: How long is production and installation?

A: Standard small/medium units: 7–15 days production; 3–7 days on‑site installation. Large or customized projects depend on final design.

Q5: Do you offer overseas service and certification?

A: Yes. We provide full export packaging, shipping documents, and overseas technical support. Products meet CE and international cold chain equipment standards.
