✅ Turnkey Eutectic Cold Chain System
Includes:
- KT-400 Cold Tubes
- Bitzer Compressor Refrigeration Unit
- Fully Integrated Insulated Box
Let us help you design the perfect configuration — from charging strategy to temperature control.
Premium Insulated Box (Optional with Full Set)
- External Dimensions: 3.05 x 1.83 x 2.1 m
- Structure: UV-resistant fiberglass (FRP) exterior, food-grade PP plastic interior
- Insulation: High-density PU foam (≥43 kg/m³), 100–110 mm thick for all walls
- Features: Two side doors + rear double doors
- Edges: Reinforced with aluminum alloy profiles
Our insulated box is engineered for maximum thermal retention, helping to extend delivery time without relying on diesel or electric compressors in transit.
Not Just for Ice Cream: Multi-Industry Applications
While this technology is trusted by premium ice cream brands for frozen product transport, its versatility makes it the ideal choice across multiple industries:
- Frozen Seafood Distribution
- Pharmaceutical & Vaccine Cold Chain
- Meat, Poultry & Dairy Logistics
- Prepared Meal & Ready-to-Eat Food Transport
- Medical Samples, Biological Materials, and Chemicals
- Urban “Last Mile” Cold Delivery Vehicles
❓ Eutectic Cold Tube System – FAQ
1. Do eutectic cold tubes need to match a specific refrigeration unit?
Yes. While eutectic cold tubes are somewhat universal in structure, they must be paired with a compatible refrigeration unit to ensure proper performance. The refrigeration unit should meet the following criteria:
- Sufficient cooling capacity to fully freeze the eutectic tubes within 6–8 hours
- Capable of reaching ultra-low temperatures (as low as -40°C)
- Compatible refrigerant (typically R404a)
- Matching power supply (e.g., 380V / 3-phase)
- Proper integration with control systems (temperature controller, auto shut-off, etc.)
We typically use German Bitzer compressors (model 4P) for high efficiency and reliability, but other brands such as Copeland, Carrier, or local systems can be used if the technical specs align.
2. Can I use your cold tubes with my own refrigeration system or truck?
Absolutely. If your existing refrigeration unit meets the required specifications (temperature, refrigerant, power), we can supply just the cold tubes and help you assess compatibility.
For OEMs or system integrators, we provide technical drawings and guidance for smooth integration into your vehicle or cold box.
3. How do I choose the right eutectic cold tube system for my business?
Here’s a simple guide:
| Criteria | Recommendation |
|---|---|
| Target Temperature | -18°C (standard frozen), -25°C (deep freeze), -40°C (premium ice cream, pharma) |
| Delivery Timeframe | 3–8 hours: basic setup; 8–24 hours: high-density setup with enhanced insulation |
| Box Size & Layout | We will help calculate tube quantity and length based on your box dimensions |
| Charging Conditions | Ensure access to 380V/3-phase power for full charge in 6–8 hours |
| Business Model | Need just tubes? Or a full set with compressor + insulated box? We offer both options |
4. What industries and products can use eutectic cold plates?
While eutectic plates are ideal for ice cream transport, they are widely used in many sectors:
- 🧊 Frozen seafood, meat, and dairy distribution
- 💊 Pharmaceuticals, vaccines, and medical samples
- 🍱 Ready-to-eat meals and frozen food delivery
- 🚚 Urban last-mile logistics in electric or small vehicles
- 🧪 Chemical and laboratory cold chain transport
5. Can you provide the full system – not just the cold tubes?
Yes! We offer a complete one-stop solution:
- Eutectic Cold Tubes (Model KT-400)
- German Bitzer Compressor + Control Panel
- Custom Insulated Box with FRP & Food-Grade Interior
- Optional: Mounting frames, accessories, drawings, and installation support
Whether you’re retrofitting your fleet or starting a cold chain delivery service, we can help build your full ultra-low temperature transport solution.
6. How long can the cold tubes maintain low temperatures during transport?
It depends on the insulation quality and ambient temperature. Generally:
- At -20°C to -40°C, cold retention lasts 8 to 24 hours
- Well-insulated boxes (PU foam ≥100mm) extend the duration
- Dual-row cold tube designs can boost endurance for long-haul routes
7. What’s the charging time and requirements for the cold tubes?
- Charging time: Approx. 6–8 hours for full freeze
- Power supply: 380V / 3-phase required
- Once charged, the system works without continuous electricity during transit
8. Do you provide global support and export services?
Yes! We provide:
- 🌍 Worldwide shipping and export-ready packaging
- 🛠 Remote technical support for installation and troubleshooting
- 🧾 Full documentation: wiring diagrams, performance data, CAD drawings
We’re committed to helping our partners around the world build sustainable, cost-effective cold chain systems.
