Snowman Group Launches New Compressors
At the prestigious 2026 China Refrigeration Exhibition, Snowman Group, 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.
SPT 42 Series Piston Compressor
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.

Industry Recognition & Market Significance
The SPT Series has already received high acclaim from the China Refrigeration Exhibition
Expert Committee, which recognized it as a landmark achievement in domestic high
pressure compression technology. By successfully overcoming historical technical
bottlenecks, Snowman Group has filled a critical gap in the domestic industrial
compressor market, positioning China at the forefront of the global natural refrigerant
revolution.
This launch solidifies Snowman Group's role as an industry leader in sustainable
refrigeration and heat pump innovation. The SPT Series not only represents a significant
leap forward in domestic substitution of high-end equipment but also provides a practical,
efficient pathway for industries worldwide to achieve energy savings, carbon reduction,
and long-term operational sustainability.
For businesses seeking to future-proof their operations, comply with stringent
environmental standards, and reduce energy costs, the Snowman SPT Series Trans-critical
Piston Compressors stand as the definitive, next-generation solution for industrial cooling
and heating.
