Adiabatic
Cooler
High-efficiency dry cooler with adiabatic pre-cooling system. Delivers reliable process cooling with dramatically reduced water consumption -- engineered for data centres, industrial plants and HVAC applications worldwide.
Why Choose Our Adiabatic Cooler
Engineered for demanding industrial environments where water conservation, energy efficiency and reliable performance are non-negotiable.
Water-Saving Design
Adiabatic pre-cooling pads activate only when ambient temperature rises above setpoint. Water consumption is reduced by up to 70% compared with conventional wet cooling towers.
High Energy Efficiency
EC fan motors with variable-speed control automatically adjust airflow to match load. Significant reduction in annual power consumption versus fixed-speed alternatives.
Closed-Circuit Fluid Protection
Process fluid circulates inside sealed coils -- never exposed to atmosphere. Eliminates contamination risk and protects sensitive equipment such as compressors and data centre chillers.
Corrosion-Resistant Construction
Hot-dip galvanised steel frame, stainless steel coils, and UV-stabilised PVC components ensure long service life even in harsh industrial and coastal environments.
Modular & Scalable
Modular cell design allows capacity expansion without system shutdown. Custom configurations from single-cell to multi-cell arrays to match any project scale.
Intelligent Control System
PLC-based controller with temperature sensors automatically switches between dry mode and adiabatic mode. Remote monitoring and BMS integration available.
Dual-Mode Cooling Operation
The adiabatic cooler intelligently switches between two operating modes based on real-time ambient dry-bulb temperature, maximising efficiency and minimising water use throughout the year.
Ambient Temperature Monitoring
Sensors continuously measure ambient dry-bulb temperature. When temperature is below the setpoint (typically 25-28°C), the unit operates in fully dry mode -- fans only, zero water consumption.
Adiabatic Pre-Cooling Activation
When ambient temperature exceeds the setpoint, the PLC activates the adiabatic pad wetting system. Water is distributed evenly over evaporative media pads positioned upstream of the coil.
Evaporative Air Pre-Cooling
Water evaporates from the pads, absorbing latent heat from the incoming air stream. Inlet air temperature is reduced by 4-8°C before reaching the finned coil surface.
Enhanced Heat Rejection
Pre-cooled air flows across the aluminium-fin coil, dramatically improving heat transfer. Process fluid outlet temperature meets design targets even during peak summer conditions.
