Industrial Evaporative Air Coolers

Industrial Evaporative Air Coolers

Discover our range of mobile evaporative air coolers for warehouses, workshops, production areas, and other industrial spaces. Efficient, economical, and easy to install, they provide a more comfortable working environment during hot weather. Available for sale and rental through Filtra International.

Industrial evaporative air coolers provide targeted cooling for warehouses, workshops, production areas and other large professional spaces where conventional air conditioning may be impractical.

These mobile industrial cooling systems use water evaporation and high airflow to reduce air temperature without refrigerant gases. Plug-and-play installation, low electrical demand and multiple airflow capacities make them suitable for local workstation cooling as well as larger industrial areas.

Industrial evaporative air coolers

Industrial evaporative air coolers provide high-volume cooled airflow for warehouses, workshops, production halls, logistics centres and other large ventilated workspaces. Mobile units can be positioned close to operators, production lines and heat-generating processes, allowing cooling to be concentrated where it is actually required.

OPERATING PRINCIPLE

Cooling through water evaporation and high-volume airflow

Warm ambient air is drawn through a water-wetted evaporative medium. As part of the water evaporates, heat is absorbed from the incoming air, reducing its dry-bulb temperature before the fan distributes the resulting cooler airflow into the workspace.

Unlike conventional compressor-based air conditioning, direct evaporative cooling does not require a refrigeration circuit or refrigerant gas. Cooling performance depends mainly on ambient temperature, relative humidity, airflow and the available air exchange through the building.

Evaporative cooling works best with continuous air renewal. Doors, windows, roof vents or mechanical extraction should allow humidified air to leave while fresh incoming air replaces it.

Warm fresh air → Evaporative cooling → Occupied zone → Air leaves building

SYSTEM CONFIGURATION

Designed for professional and industrial cooling

Mobile installation

Castor-mounted equipment can be repositioned between workstations, departments and seasonal cooling zones.

High-volume airflow

Airflow capacities from approximately 5,000 to 48,000 m³/h support local cooling through to large industrial work zones.

Evaporative cooling

Water evaporation reduces incoming dry-bulb temperature without a conventional refrigeration compressor.

Adjustable airflow

Fan output can be adjusted to match operator position, cooling demand and changing working conditions.

Industrial pre-filtration

KM industrial configurations incorporate G4 incoming-air pre-filtration to reduce coarse dust entering the cooling system.

2027 connected models

The 2027 generation includes Wi-Fi connectivity for remote operation and access to operating information.

TYPICAL APPLICATIONS

Where industrial evaporative cooling is commonly used

Warehouses & logistics Industrial production Automotive workshops Industrial laundries Metalworking Food production Paper & printing Aircraft maintenance Vehicle maintenance Temporary work areas

Spot cooling and zone cooling are particularly useful where workers occupy defined areas within a much larger building.

COOLER SELECTION

What should be considered when selecting an air cooler?

Floor area & ceiling height Building volume is often more useful than floor area alone.
Internal heat load Machinery, ovens, dryers, vehicles and solar gain can significantly increase cooling demand.
Temperature & humidity Evaporative cooling potential is greatest in hot, relatively dry conditions.
Ventilation Humidified air requires an effective route out of the building.
Cooling objective Determine whether the requirement is spot cooling, zone cooling or broader distributed cooling.
Airborne contamination Industrial environments containing dust may benefit from G4 incoming-air pre-filtration.
Water supply Reservoir capacity, water consumption and automatic water connection should be considered.
Mobility & operating pattern Mobile units can be repositioned as production layouts and seasonal requirements change.

FREQUENTLY ASKED QUESTIONS

Industrial evaporative air cooler FAQ

How does an industrial evaporative air cooler work?
An industrial evaporative air cooler draws warm air through a water-wetted evaporative medium. Water evaporation absorbs heat from the incoming air before a high-volume fan distributes the resulting cooler airflow into the workspace.
Where can industrial evaporative air coolers be used?
Typical applications include warehouses, logistics centres, manufacturing plants, automotive workshops, industrial laundries, food production, metalworking, paper production and large maintenance facilities.
Do doors and windows need to remain closed?
No. Direct evaporative cooling normally requires continuous air exchange. Doors, windows, roof vents or mechanical extraction allow humidified air to leave while fresh incoming air replaces it.
Does an evaporative air cooler use refrigerant gas?
No. Direct evaporative cooling uses water evaporation rather than the refrigeration compressor and refrigerant circuit used by conventional air-conditioning systems.
How do I select the correct industrial air cooler?
Selection should consider airflow requirement, floor area, ceiling height, internal heat load, temperature, relative humidity, ventilation, cooling zone, water supply and operating conditions.
Can evaporative coolers be used for workstation cooling?
Yes. Mobile units can be positioned close to operators, production lines and heat-generating equipment to create targeted cooling zones without treating the complete building volume.
Are industrial air coolers available for rental?
Yes. Filtra International supplies mobile evaporative air coolers for both purchase and rental, subject to availability.
