Core Advantages

● Ultimate Energy Efficiency, Significant Cost Reduction: Intelligent variable frequency modulation precisely matches real-time load, reducing annual average energy consumption by 30%-40%.

● Smooth, Quiet & Exceptionally Reliable: Soft start protects equipment; ±0.1°C precise temperature control ensures process stability and product quality.

● Environmentally Forward, Future-Ready: Uses eco-friendly refrigerants with zero ODP and low GWP, complying with stringent international environmental regulations.

● Smart Control, Hassle-Free Operation: High-definition touchscreen and remote monitoring capabilities enable energy management and predictive maintenance.


Professional Application Areas

● Aluminum Profile Extrusion & Cooling

Provides rapid and uniform cooling for molds and the extrusion process after aluminum billet heating, effectively improving material hardness, surface finish, and production efficiency, while preventing profile deformation.

● Grinding & Mixing Processes

Precisely removes significant heat generated during chemical reactions or material mixing in grinding and high-speed agitation processes, ensuring stable process temperatures and safeguarding product quality and production safety.

● New Energy Manufacturing

Covers cooling for critical processes like lithium battery slurry mixing, coating, and calendering, as well as precise temperature control in photovoltaic silicon wafer and fuel cell production. A core equipment for ensuring product consistency, safety, and yield.

● Chemical & Pharmaceutical

Provides high-precision process cooling for reactors, distillation columns, and bio-fermentation processes, ensuring chemical reactions occur at optimal temperatures and guaranteeing product purity and production efficiency.

● Food Cooling & Freezing

Used for rapid food cooling, freezing, and central air conditioning systems, providing hygienic, stable, and reliable cooling sources that meet food safety regulations.

● Plastic Molding

Provides rapid cooling for injection molding machines and extrusion machine molds, significantly shortening product cycle times, reducing product internal stress, and improving surface quality.

● Central Air Conditioning & Data Centers

Provides efficient and reliable cooling sources for commercial buildings, hospitals, electronic cleanrooms, and data centers, creating comfortable and healthy indoor environments and ensuring the stable operation of critical facilities.

● Machine Tools & Cutting Processes

Provides precise cooling for machining center spindles and cutting fluids, effectively controlling thermal deformation during processing, ensuring the machining quality of high-precision parts, and extending machine tool service life.
