Fluidized Cooling, Uniform Sand Temperature
Sand particles are fully suspended—no dead zones, discharge temperature variation ≤3°C, ensuring uniform resin reaction and fewer casting defects.

High Cooling Efficiency, Low Energy
Energy consumption 30–50% lower than rotary drum coolers, cooling time 3–5 minutes, capacity 1.5–2.5 t/(h·m²)—significant energy savings.

Compact Structure, Stable Operation
No moving parts in bed—low failure rate, minimal maintenance
Perforated plate: wear-resistant stainless steel or ceramic composite, lifespan ≥10,000 hours
Overall lifespan ≥12 years

Rapid cooling of hot reclaimed sand in resin sand reclamation lines

Precise control of sand temperature and moisture before mixing

Integrated with S25 mixer, GTD elevator, and dust collector for full automation

Supports multi-temperature settings for different molding lines

Connects to MES for traceability and energy management
