What applications is this NH₃ evaporator suitable for?

This NH₃ (ammonia) evaporator, designed for −40 °C evaporation temperature, pump-fed liquid supply, and 50 kW cooling capacity, is specifically suited for industrial low-temperature refrigeration applications where high efficiency and reliability are required.

Suitable Applications for This NH₃ Evaporator

1. Low-Temperature Cold Storage Rooms

• Freezer rooms operating at −30 °C to −40 °C

• Long-term storage of frozen foods

• Central ammonia refrigeration plants with pump circulation

Typical products:

• Frozen meat and poultry

• Seafood and fish

• Frozen fruits and vegetables

2. Food Processing and Freezing Facilities

• Pre-freezing and holding rooms

• Buffer cold rooms between processing and blast freezing

• Areas requiring stable, uniform low temperatures

Ammonia is preferred due to its high heat transfer efficiency and low operating cost.

3. Blast Freezing and IQF Support Systems

• Used as part of multi-evaporator systems supporting blast freezers or IQF lines

• Suitable where high frost loads occur and water defrosting is required

• Pump-fed design ensures even refrigerant distribution under high load conditions

4. Meat, Poultry, and Seafood Plants

• Carcass chilling and frozen storage rooms

• Processing environments with high humidity and frequent door openings

• Applications where fast heat removal and reliable defrost are critical

5. Industrial Refrigeration Systems

• Large-scale central ammonia plants

• Cold warehouses and logistics centers

• Facilities requiring continuous operation and high system uptime

6. Pharmaceutical and Chemical Cold Storage

• Storage of temperature-sensitive raw materials

• Low-temperature process cooling

• Applications requiring stable operation at ultra-low temperatures

7. Cold Rooms with Heavy Frost Formation

• Environments with frequent moisture ingress

• Applications benefiting from water defrost, which is faster and more effective than air defrost at −40 °C

Summary

This NH₃ evaporator is best suited for:

• −40 °C low-temperature refrigeration

• Pump-circulated ammonia systems

• Industrial and food-grade applications

• High humidity, high frost-load environments

• Central refrigeration plants requiring reliability and efficiency

It is not typically intended for small commercial refrigeration or DX systems, but rather for professional industrial ammonia refrigeration installations.
