Snowman Group Launches New Compressors
Snowman Group Launches SPT Series Trans-critical Piston Compressors
At the prestigious 2026 China Refrigeration Exhibition, Snowman Group (SNOWMAN), a pioneer in global refrigeration and heat pump solutions, officially unveiled its game-changing SPT Series Trans-critical Piston Compressors (Industrial Edition). Engineered for the most demanding industrial environments, this advanced compressor lineup marks a major technological breakthrough, addressing critical industry challenges and accelerating the global transition to low-carbon, natural refrigerant-based systems.
SPT 41 Series Piston Compressor
A Breakthrough for High-Pressure, Sustainable Industrial Applications
The SPT Series is purpose-built to operate under the extreme pressures of trans-critical cycles, with a maximum working pressure rating of 160 bar—a design that ensures unrivaled durability and stability.
Unlike traditional systems relying on synthetic refrigerants with high Global Warming Potential (GWP), the SPT Series utilizes natural refrigerant (ODP=0, GWP=1), offering an inherently eco-friendly solution that aligns with the strictest international environmental regulations and global "dual carbon" goals.
This industrial-grade compressor series is available in 2, 4, 6, and 8-cylinder configurations, providing a versatile range of capacities to match diverse industrial scales and applications. Engineered for continuous, high-load operation, it reliably delivers hot water up to 90°C, making it exceptionally efficient for industrial heat pumps, process heating, and combined cooling & heating systems.

Core Technological Innovations & Superior Engineering
The SPT Series embodies Snowman Group's decades of expertise in high-pressure compression technology, featuring seven core technological advancements:
Ultra-High-Strength Materials: Key components are forged from specialized alloys and high-grade ductile iron castings, engineered to resist corrosion, fatigue, and the extreme mechanical stress of supercritical conditions.
Optimized High-Pressure Structure: A robust, specially designed crankcase and cylinder assembly minimizes deformation under pressure, while an advanced valve plate system with impact-resistant spring steel valves ensures rapid, reliable gas exchange and long service life.
Enhanced Reliability & Safety: Equipped with integrated safety valves, high-pressure motor protection modules (INT69B2), and built-in high-density suction filters, the compressors deliver exceptional operational safety and protect critical internal components from contaminants.
Minimized Oil Carryover: Precision-engineered internal geometries significantly reduce refrigerant oil dissolution, ensuring optimal lubrication, consistent performance, and higher system efficiency.
Compact, Balanced Design: The crankshaft features an integrated counterweight design, crafted from specially heat-treated, high-strength materials for maximum durability and smooth operation under heavy loads.
Wide Application Flexibility: Engineered to excel in both trans-critical refrigeration and heat pump cycles, offering exceptional adaptability across temperature ranges and operational modes.
Advanced Thermal Stability: Superior material selection and structural design withstand extreme temperature fluctuations and large differential temperatures between suction and discharge sides.
Key Applications & Industry Impact
The SPT Series is ideally suited for a wide spectrum of heavy-duty industrial applications, including:
Industrial Heat Pumps & District Heating: Efficient, low-carbon replacement for traditional boilers, providing sustainable process heat and hot water.
Food & Beverage Processing: Precise temperature control for dairy, meat, and frozen food production, ensuring product integrity and safety.
Cold Chain & Logistics: High-efficiency refrigeration for large-scale warehouses, distribution centers, and low-temperature transport.
Ice Rinks & Sports Facilities: Reliable, precise cooling for ice surfaces with superior energy efficiency.
Chemical & Pharmaceutical Processing: Stable, safe cooling for temperature-sensitive industrial processes.
