1. Integrated & Compact Design
- All core components (compressor, condenser, fans, control system, refrigerant piping) are factory-assembled into a single weatherproof metal cabinet.
- The dual-fan vertical layout minimizes footprint, making it ideal for wall/roof mounting on small-to-medium cold rooms.
- Robust anti-corrosion metal casing ensures durability in humid, low-temperature cold room environments.
2. Efficient Heat Dissipation & Cooling Performance
- Equipped with two large-diameter axial fans for forced air cooling, significantly improving condenser heat exchange efficiency.
- High-efficiency copper tube-aluminum fin condenser coils optimize heat transfer, supporting stable operation in high ambient temperatures.
- Compatible with both fresh-keeping (2–8°C) and freezing (-18°C to -25°C) temperature ranges, suitable for diverse cold storage needs.
3. Intelligent Control & Safety Protection
- Built-in precision digital temperature controller with ±0.5°C temperature accuracy, supporting auto-defrost (electric/hot gas type) and timer functions.
- Comprehensive safety protections: high/low pressure switch, overload protection, phase sequence/phase loss protection, anti-short cycle protection, and frost protection to prevent equipment damage.
- Optional IoT remote monitoring for real-time temperature tracking and fault alarm notifications.
4. Plug-and-Play Installation & Easy Maintenance
- Factory pre-charged with refrigerant and pre-tested for leaks, eliminating complex on-site piping work.
- Side access panels allow quick maintenance of core components (compressor, valves, filters, control board), reducing downtime and labor costs.
- Standardized components simplify replacement and after-sales service.
5. Energy Efficiency & Environmental Compliance
- Typically uses hermetic scroll compressors (e.g., Copeland/Emerson) with high COP (Coefficient of Performance) and low noise levels.
- Supports eco-friendly refrigerants (R404A, R452A, R290) to meet global low-GWP (Global Warming Potential) regulations.
- Inverter-driven models (optional) adjust compressor speed based on cooling load, further reducing power consumption during partial-load operation.
6. Application Scenarios
- Ideal for small commercial cold rooms (convenience stores, restaurants, fresh produce shops), pharmaceutical cold storage, and small-scale industrial freezing facilities.
- Suitable for both new cold room installations and retrofitting existing systems.

Here are four specific application scenarios of packaging machinery:
1. Food & Beverage Industry
- Fresh produce & agriculture: Storage of fruits, vegetables, and grains to extend shelf life and prevent spoilage.
- Meat & seafood: Chilled storage of raw meat, fish, and seafood, as well as frozen storage for long-distance logistics.
2. Pharmaceutical & Medical Industry
- Vaccine & biologic storage: 2–8°C refrigeration for vaccines, blood products, and biological samples.
- Laboratory cold storage: Low-temperature freezers (-20°C to -80°C, depending on model) for reagents, cell cultures, and clinical samples.
3. Logistics & Retail Industry
- Supermarkets & convenience stores: Walk-in cold rooms for perishable goods.
- Third-party logistics (3PL): Shared cold storage facilities for e-commerce and cross-border trade.
- Cold chain distribution: Pre-cooling and temporary storage during transport.
4. Floriculture & Horticulture
- Cut flower storage: 2–8°C cold rooms to preserve freshness and extend vase life.
- Nursery & seed storage: Controlled low-temperature environments for seed viability.
1. Power On: Flip the main circuit breaker to supply power to the unit. The controller will light up and enter standby mode.
2. Set Target Temperature:
- Press the SET button on the controller to enter temperature setting mode.
- Adjust the target temperature (e.g., 2°C for fresh-keeping, -18°C for freezing) using the ▲ / ▼ keys.
- Confirm the setting by pressing SET again; the unit will automatically start the cooling cycle.
3. Initial Run Monitoring:
- Observe the fans: Both axial fans should start spinning within 1–3 minutes, blowing air outward from the unit.
- Listen for the compressor: A low, steady hum indicates normal operation (no loud knocking or rattling).
- Check the cold room temperature: It should gradually drop to the set target within the expected time.
Q1: What kind of technical support can you provide?
A: Both our sales and engineers can provide 24 hours online support. Panels are supplied with installation drawings.Installation manuals and electrical diagrams are included with the cooling system. Accessories support is available for all of our products.
Q2: How long is the lead time?
A: Usually for units we need 5-35 days to produce.Panels and other things usually we need 5-10 days depends on amount.
Q3:Do you accept customization?
A: Since we are a factory,we accept customer's customization. If you need to use your brand,please provide the Al/PSD source file of the brand logo.
