Industrial Evaporative Cooling Systems | High-Volume Direct & Indirect Air Coolers for Manufacturing Facilities
Mechanical refrigeration remains cost-prohibitive for cooling large industrial open-bay facilities and high-heat production floors. Industrial evaporative cooling systems leverage the natural enthalpy of vaporization to drop supply air temperatures by 5°C to 12°C using a fraction of the electrical power required by compressor-based chillers. These units pull outdoor dry air through cross-fluted cellulose or fiberglass evaporation media, continuously saturating and delivering high volumes of chilled, filtered air to displace trapped internal heat loads.
Product Range
Roof-Mounted Axial Evaporative Coolers:
High-CFM discharge units (18,000 to 60,000 m3/h) configured for large warehouse and distribution center roof installations.
Side-Discharge Industrial Wall Coolers:
Heavy-gauge galvanized or UV-stabilized polymer cabinet units mounted exteriorly to factory sidewalls.
Indirect-Direct Evaporative Cooling (IDEC) Units:
Two-stage systems combining plate heat exchangers and evaporative media to lower supply air dew points without adding moisture to cleanrooms or sensitive assembly areas.
Rigid Cooling Pads & Replacement Media:
Cross-fluted 7090 and 5090 cellulose paper pads treated with anti-rot chemical impregnations.
Key Performance Features
Cross-Fluted Evaporative Media: Engineered with 45/45 flute angles to maximize air-water contact surface area while maintaining low static pressure drops.
Direct-Drive VFD Fan Assemblies: Dynamically balanced airfoil impellers driven by variable frequency inverter motors, adjusting airflow output to match real-time thermal shifts.
Automatic Bleed-Off Systems: Timed flush cycles purge concentrated mineralized water from the basin every 4 to 8 hours, preventing scale buildup and extending pad operating life.
UV-Sterilization Water Loops: Integrated ultraviolet germicidal lamps neutralize bacteria and algae within the recirculation sump reservoir.
UV-Stabilized Structural Housing: Injection-molded heavy-duty structural polypropylene or powder-coated galvanized steel cabinets resistant to prolonged solar radiation and salt mist corrosion.
How to Choose
Calculate Required Airflow (CFM):
Multiply facility volume (cubic feet) by desired Air Changes Per Hour (ACH) based on heat load (typically 20 to 40 ACH for industrial spaces):
CFM = (Building Volume (cu. ft.) × ACH) / 60
Evaluate Climate Psychrometrics:
Verify local outdoor wet-bulb depressions. Evaporative cooling operates at peak efficiency in dry, low-relative-humidity regions (RH < 40%).
Determine Static Pressure Requirements:
Account for ductwork friction losses, discharge grilles, and louver resistance when selecting centrifugal versus axial fan configurations.
Select Water Supply Standards:
Confirm incoming municipal water hardness and pressure levels to size anti-scalant filtration and float-valve inlets correctly.
Typical Applications
Logistics & Warehousing:
Lowers indoor ambient temperatures across e-commerce fulfillment centers without sealing loading dock doors.
01
Automotive & Metal Stamping:
