Cooling (Commercial)

Mobile adiabatic cooling systems for halls: economical alternative to air conditioning (without refrigerants)

Is it too warm in your hall in summer? Our mobile evaporative coolers (adiabatic air coolers) quickly improve the working climate, energy-efficiently and environmentally friendly – without climate-damaging refrigerants and without fixed installation.

Noticeably cooler through evaporation effect (depending on conditions up to approx. 10 °C)
Very low power consumption (e.g., 750 W for the OKM 22 for approx. 150–250 m²)
Mobile & flexible thanks to wheels, water tank, and optional fixed water connection
Industrial-grade for workshops, warehouses, logistics, and production halls

Rent for 1 month without obligation: Rental costs are credited towards purchase.

When halls overheat in summer: better working conditions without air conditioning

In many businesses, high temperatures develop in summer due to machine heat, sunlight, and large hall volumes. Classic air conditioners are often expensive to purchase and operate in halls and require complex installation. Adiabatic cooling systems are a practical solution for many commercial applications: efficient, mobile, and quickly ready for use.

Advantages of adiabatic hall cooling (evaporative cooling)

Energy efficient: No compressor technology – usually significantly lower power consumption than classic air conditioners.
Without refrigerants: No climate-damaging gases, no outdoor unit, no complex installation.
Fresh air principle: Continuous supply of cooled air instead of pure recirculation.
Mobile & ready to use immediately: Set up, plug in, fill the tank or connect water – done.
Optional with air treatment: Depending on the model, with ionizer/UV technology to improve air quality.

Important: The achievable temperature reduction depends, among other things, on starting temperature, humidity, Hall layout and air exchange. Please refer to the temperature chart in the respective product.

How does adiabatic cooling work?

Evaporative coolers (also adiabatic coolers or mobile air coolers for halls) use the natural principle the evaporation:

Warm air is drawn in.
The air flows through water-soaked cooling pads.
The cooled, slightly humidified air is released into the room.

Humidity typically rises only moderately (often about 2–5%) and is hardly noticeable in many applications.

Which size fits? Compare models by hall area

The area specifications are guidelines and depend on the application conditions. For a reliable design, we are happy to advise you.

Model	Recommended area (guideline)	Airflow	Power consumption	Tank / Water	Noise
OKM 05	up to approx. 50 m²	5,000 m³/h	see product data	90 L (auto/manual)	approx. 53/58/63 dB
OKM 12	approx. 80–150 m²	12,000 m³/h	500 W	70 L / 1/2"	54–63 dB
OKM 22	approx. 150–250 m²	22,000 m³/h	750 W	130 L / 1/2"	< 70 dB
OKM 30	approx. 200–400 m²	30,000 m³/h	1,110 W	200 L / 1/2"	< 70 dB

FAQ: Frequently asked questions about adiabatic hall cooling

How much does an adiabatic air cooler cool a hall?

Depending on starting temperature, humidity, air exchange, and hall layout, noticeable cooling is possible – under suitable conditions up to about 10 °C. The temperature chart in the respective product is decisive.

Does the humidity increase significantly?

In many applications, humidity only rises moderately (often about 2–5%). The actual change depends on the application.

Do I need an installation like with an air conditioner?

No. Mobile devices are set up and operated with electricity and water (tank or connection). No refrigerants are needed. and no outdoor unit required.

How is the delivery carried out?

Due to the device dimensions, delivery is usually by freight forwarder on a pallet. Please plan accordingly depending on the model approx. 1 week delivery time.

Are there discounts when buying multiple devices?

Yes. With multiple devices, the share of transport costs decreases – we are happy to prepare a custom offer.
