Looking for high-efficiency natural refrigeration? Here are the technical facts on SRMTEC Ammonia (R717) Package Units:
Engineered as pre-assembled, factory-tested skids, these packages are optimized for industrial refrigeration, blast freezing, and process cooling. They are split into two distinct lines to match your specific engineering footprints:
1️⃣ SRS Series (Semi-Hermetic Screw Packages)
• Leak Elimination: Features an integrated Permanent Magnet Synchronous Motor (PMSM). By fully enclosing the motor, it completely eliminates the traditional mechanical shaft seal—the #1 source of ammonia leaks.
• Staging Flexibility: Available in both Single-Stage (medium/high temp) and Double-Stage (low-temp compound) configurations to match specific compression ratios.
• Application: Ideal for urban areas, commercial cold storage, or facilities with strict safety footprints.
2️⃣ SRM Series (Open-Type Screw Packages)
• Extreme Low Temperatures: Built for heavy industrial loads, operating efficiently at evaporating temperatures down to -65°C.
• Patented Efficiency: Utilizes an asymmetric 5+7 lobe rotor profile, delivering higher volumetric efficiency and lower power consumption than standard profiles.
• Capacity Control: Features stepless mechanical volume ratio (Vi) and capacity adjustment to match fluctuating cooling loads exactly.
The Bottom Line: Pre-engineered skids reduce field piping, minimize site commissioning time, and future-proof facilities against synthetic F-gas regulations with a high-ROI natural refrigerant.
