This low-temperature unit operates on a 380V/50HZ/3PH power supply and uses R507A refrigerant (indicated by “C” in the model name). It is designed for an evaporating temperature of -32°C and condensing temperature of 36°C (standard working conditions). Cooling capacity ranges from 133.6 kW (TQ-C-L-D-SRL200E-2-Z, 2 parallel compressors) to 538.8 kW (TQ-C-L-D-SRL510E-3-Z, 3 parallel compressors). Refrigerant displacement varies from 400 m³/h (2-compressor models) to 1,530 m³/h (3-compressor models). The semi-hermetic screw compressors (SRL series) have a power range of 20 HP–50 HP per unit, and the barrel pumps feature a flow rate of 200 m³/h–510 m³/h per pump. The unit includes a shell-and-tube condenser (water-cooled) or copper-tube aluminum-fin condenser (air-cooled), with a built-in oil separator and liquid receiver.

Medium & Low-Temp Cold Storage: Perfect for large warehouses storing frozen goods (-25°C to -18°C) and fresh produce (0°C to +15°C). The modular design allows separate temperature zones, meeting mixed-storage needs (e.g., frozen meat and fresh vegetables in the same facility).

Industrial Process Cooling: Provides efficient cooling for low-temperature industrial processes (e.g., plastic film production, rubber vulcanization). It maintains process temperatures at -10°C to +5°C, ensuring product consistency and reducing scrap rates by 18%.

Agricultural Product Pre-Cooling: Used in pre-cooling rooms for fruits (e.g., apples, bananas) and vegetables (e.g., lettuce, tomatoes). It quickly removes field heat (from +30°C to +5°C in 1–2 hours), extending shelf life by 50% and preserving nutritional value.

Commercial Refrigeration for Large Retailers: A cost-effective solution for supermarket back-room storage and distribution centers. The R507A refrigerant meets global environmental standards, and the unit’s large capacity supports 1,000+ m² of retail cold storage.

Logistics & Distribution Hubs: Ensures temperature consistency (-20°C to +8°C) during short-term storage and handling of goods in transit (e.g., cross-border cold-chain trucks, port warehouses). The reliable pump circulation prevents temperature fluctuations during door openings.

Q: What is the MOQ?

A: 1 piece, supporting both single-unit purchases and large-scale projects (e.g., 5+ units for 50,000 m² cold storage).

Q: What is the lead time?

A: 2–4 weeks. 3-compressor models or custom condenser types (e.g., air-cooled for water-scarce areas) may require an extra 5–8 days.

Q: What are the payment terms?

A: For orders over 10,000 USD: 30% deposit in advance, 70% before goods loading. For orders under 10,000 USD: 100% advance payment.
