18000 (m³/h) Environmentally Certified AC Side air outlet 220v/380v/50 Axial Flow RUNDONGFANG RDF-18B Eco-Cooling System: Advanced Adiabatic Technology The RDF-18B leverages adiabatic evaporative cooling—a zero-refrigerant process mimicking natural thermodynamic principles. Ambient air is drawn through a nano-coated cellulose matrix saturated with water, triggering rapid evaporation that reduces air temperature by absorbing latent heat. A variable-speed centrifugal
