Extreme High-Temperature Resistance, Safe & Reliable
FRP shell: High-temp unsaturated polyester + multi-layer E-glass, continuous use ≥90°C, short-term 100°C thermal shock
Fill media: Modified PP or high-temp PVC, softening point ≥95°C—resists deformation and collapse
Metal parts: Hot-dip galvanized + epoxy coating or 304/316L stainless steel—prevents high-temp corrosion

High-Efficiency Heat Transfer, Close to Wet-Bulb Limit
High-temp fill with large spacing prevents clogging and ensures smooth airflow
Optimized water distribution with anti-clogging nozzles—uniform spray, thermal performance meets NB/T 35037 Class I
Closed-type: Dual-layer 316L stainless steel coil, 1.6 MPa pressure rating, chloride corrosion resistant, lifespan ≥10 years

Intelligent Control, Energy Savings
Optional VFD fans + multi-stage control—automatically adjusts airflow based on water temperature, saving 20–40% energy
Integrated temperature sensors + PLC control—supports local/remote monitoring, fault alarms, runtime tracking, energy stats
Compatible with MES/SCADA for data integration and centralized management

Anti-Corrosion & Anti-Scaling, Easy Maintenance
Closed-type: Full closed-loop circulation—prevents contamination and scaling, ideal for softened/pure water systems
Open-type: Optional automatic blowdown + water quality monitoring—reduces water treatment cost
Modular design—quick replacement of fill, nozzles, fans—maintenance time reduced by 50%

MF/FF Induction Furnaces: Cooling power cabinets, capacitors, induction coils

Cupolas & Arc Furnaces: Jacket cooling, waste heat recovery, extended furnace life

Hydraulic & Lubrication Stations: Prevents oil overheating and system failure

Air Compressors & Vacuum Pumps: Improves compression efficiency, reduces energy use

Molding & Core-Making Equipment: Ensures continuous operation, improves cycle time
