Ammonia Gas Shell Tube Exchanger

Core Components & Materials

◆ Tube Material: ASTM A179 steel tubes. These tubes have a 35mm outer diameter and a 2.5mm wall thickness, providing excellent corrosion resistance and structural strength for handling ammonia refrigerant.
◆ Tube Sheet & Fin Design: Tubes are expanded into steel tube sheets for a leak - proof joint. Optimal aluminum fins (0.5mm pitch) are used to enhance heat transfer efficiency by 40%, ensuring rapid cooling of ammonia gas.

Performance Parameters

◆ Temperature Range: Operates between - 30°C and 150°C, making it suitable for a wide range of industrial refrigeration applications, from low - temperature cold storage to moderate - temperature process cooling.
◆ Cooling Capacity: Cools ammonia gas from 120°C to 40°C in industrial freezers, supporting cold storage capacities of 50 - 5000 tons. This enables it to meet the cooling demands of various scales of food processing and pharmaceutical facilities.

Structural Design & Efficiency

◆ Vertical Design: The vertical structure prevents ammonia pooling, ensuring safe and efficient operation. This design is particularly important in food processing and pharmaceutical industries where safety and product quality are critical.
◆ Heat Transfer Enhancement: The use of aluminum fins with a 0.5mm pitch significantly improves heat transfer, allowing the exchanger to efficiently manage the cooling process and maintain stable refrigeration performance.

Application Scenarios

◆ Designed for industrial refrigeration systems, it is widely applicable in food processing facilities (such as cold storage for perishable goods) and pharmaceutical warehouses (for temperature - sensitive drug storage). It provides reliable cooling for ammonia - based refrigeration systems, ensuring the integrity of products that require strict temperature control.

Key Advantages

◆ Corrosion Resistance: Constructed with stainless steel (ASTM A179 tubes) and steel tube sheets, it offers excellent resistance to ammonia corrosion, ensuring a long service life in harsh refrigeration environments.

◆ Leak - Proof Joints: Tubes are expanded into steel tube sheets, creating leak - proof connections that prevent ammonia leakage, enhancing the safety of the refrigeration system.

◆ Efficient Heat Transfer: Aluminum fins with a 0.5mm pitch boost heat transfer by 40%, enabling rapid cooling of ammonia gas and improving the overall efficiency of the refrigeration cycle.

◆ Safe Operation: The vertical design prevents ammonia pooling, reducing the risk of safety hazards and ensuring stable operation in food processing and pharmaceutical facilities.

Technical Compliance

◆ Complies with industry standards for ammonia refrigeration equipment. The use of ASTM A179 steel tubes and the design of leak - proof joints meet the safety and performance requirements for industrial refrigeration systems, ensuring reliable and safe operation.

Packaging & Logistics

◆ Packaging: Protected with anti - corrosion materials (e.g., plastic film) and shock - resistant padding (e.g., foam) to prevent damage during transportation. It is then placed in a sturdy wooden crate or suitable container for safe delivery.
◆ Delivery Time: Typically 9 - 19 working days after order confirmation, depending on the order quantity and customization needs. Shipping can be arranged via land, sea, or air freight as per customer requirements, with proper handling to ensure the product arrives in good condition.
