In the highly competitive shrimp processing industry, companies must not only address challenges like soaring energy costs and increasingly stringent food safety regulations, but also maintain product quality in harsh tropical environments. Refrigeration systems typically account for 80% of a factory’s total energy consumption, making the selection of appropriate refrigeration solutions directly impact corporate profit margins and long-term development. Among various refrigerant options, natural refrigerants have consistently been the industry’s preferred choice due to their superior thermodynamic performance and long-term operational cost advantages.

Key Factors Affecting Refrigeration Energy Efficiency
Several important aspects directly influence daily energy consumption in your refrigeration setup.
System Type and Refrigerant Choice
The selected refrigerant and general configuration make a huge difference. Natural refrigerants such as ammonia provide outstanding heat transfer capabilities that noticeably lighten the load on compressors.
Compressor Technology and Design
Modern compressors equipped with accurate capacity adjustment keep performance at peak levels even when production loads change throughout the day. This feature prevents unnecessary power usage during quieter periods.
Heat Rejection and Evaporation Components
Well-designed condensers effectively lower condensing temperatures in hot surroundings, and properly chosen evaporators distribute cold air evenly across freezers and storage rooms. Together, these elements contribute significantly to overall savings.
Ammonia-Based Refrigeration Systems
The ammonia system delivers significant advantages, particularly in large-scale operations where reliability and cost control are paramount.
These setups perform exceptionally well because ammonia delivers far better thermodynamic efficiency than many synthetic options available today.
Natural Refrigerant with Superior Thermodynamic Properties
Ammonia consistently achieves higher coefficients of performance, which simply means you obtain more cooling output for every unit of electricity consumed. Additionally, its natural properties allow systems to operate smoothly under heavy demands common in seafood plants.
Proven Performance in Large-Scale Food Processing
Many high-volume facilities depend on ammonia to maintain the exact low temperatures essential for rapid shrimp freezing. Over years of real-world use, it has demonstrated unmatched stability and consistent results.
Long-Term Operating Cost Advantages
Reduced daily energy use combined with very low refrigerant leakage rates lead to impressive savings that accumulate quickly. Furthermore, maintenance requirements remain reasonable, helping you keep total ownership costs under control.
CO₂ Cascade and Transcritical Systems
Such configurations prove particularly valuable when your process demands temperatures well below -35°C, typical for individual quick freezing of shrimp products.
Excellent Efficiency at Low Temperatures
The clever cascade approach optimizes each separate stage, thereby cutting total power requirements for deep-freezing tasks. As a result, you enjoy strong performance without excessive energy draw.
Enhanced Safety Through Secondary Loop Design
By confining ammonia mainly to the machine room and using CO₂ in processing areas, the setup greatly improves overall plant safety. This separation reduces risks while still delivering the needed cooling power.
Growing Adoption in Sustainable Seafood Facilities
More processors choose these environmentally responsible systems to meet stricter global rules and satisfy customer preferences for greener operations. Consequently, adoption continues to rise steadily across the industry.
Traditional Freon and Alternative Solutions
While older synthetic refrigerant systems may still be encountered, they are increasingly revealing their limitations in today’s harsh environments. Regulatory pressures and inherent performance limitations make such devices unsuitable for new installations or major upgrades.
Higher GWP and Phase-Out Pressure
Synthetic refrigerants generally carry much greater global warming potential and now face ongoing worldwide restrictions. Therefore, relying on them exposes your operation to future compliance challenges.
Lower Efficiency in Tropical Conditions
These options typically demand considerably more energy to function effectively when ambient temperatures stay high, common in major shrimp-producing countries. This extra effort directly translates into higher monthly bills.
Limited Scalability for High-Capacity Plants
When you plan to expand production volume, synthetic-based setups often require oversized components that drive up both initial investment and running expenses. Thus, growth becomes more costly than necessary.
Why MOON-TECH Delivers the Most Energy-Efficient Solution
Partnering with seasoned suppliers who specialize in developing fully integrated high-performance components tailored for seafood processing can provide a significant competitive edge. One recent complete turnkey installation for an 80-ton-per-day shrimp facility clearly illustrates this successful strategy, incorporating various freezing techniques along with eight robust screw compressors to ensure smooth and highly efficient daily operation.
Advanced Open-Type Screw Compressors for Maximum COP
Open-type single-stage dan compound two-stage screw refrigeration compressor units manage broad temperature ranges with ammonia, providing outstanding efficiency for both medium and ultra-low temperature applications such as quick freezing. Their open design also simplifies routine maintenance, which helps maintain peak performance over many years.
High-Performance Evaporative Condensers for Optimal Heat Rejection
Evaporative condensers feature innovative patented coil arrangements and variable frequency drives that substantially reduce electricity consumption, proving especially effective in warm climates through smart options like seasonal air-cooling operation. Moreover, the absence of filler material lowers long-term cleaning and upkeep efforts.
Successful Track Record in Shrimp Processing EPC Projects
Reliable project execution, including the mentioned high-capacity shrimp installation, combines these proven components into cohesive systems that deliver dependable low-energy performance while supporting intensive daily throughput for freezing and cold storage. This integrated approach ensures you receive maximum value from day one.
