Snowkey SRM refers to the industrial refrigeration compressors and packaged systems produced by the Snowkey brand (part of Snowman Group) utilizing technology from the renowned Swedish engineering company Svenska Rotor Maskiner (SRM).
SRM invented the screw compressor in 1934, and Snowkey integrates this patented, high-efficiency technology into its global commercial and industrial freezing solutions.
Snowkey's SRM compressor systems are highly regarded for their energy efficiency, reliability, and use of eco-friendly refrigerants.

Key features of these systems include:
1️⃣ Advanced Rotor Profile:
Utilizes the patented 5+7 lobe rotor ratio, providing smooth operation and high-efficiency gas compression.
2️⃣ Automation & Intelligent Control:
Features touch panels for real-time system monitoring, preventive safety mechanisms, and automatic capacity/power control for unattended operations.
3️⃣ Energy Savings:
Many units come with vector frequency conversion (inverter) technology that adjusts rotational speeds based on varying loads to lower operational costs.
4️⃣ Refrigerant Compatibility:
Designed to work efficiently with natural and environmentally friendly refrigerants, including ammonia (R717), CO2, R404A, and R507A.
