Air-Air systems (AA)

Air-Air coolers are used to cool (or heat) objects in containers. Heat is absorbed and dissipated by heat exchangers equipped with fans. Simply cut a hole, plug in the assembly and connect it to a power source. Our Air-Air coolers are designed for dependable, compact performance.

Tunnel Series
Two of our smallest coolers, AA-026 and AA-033, are based on a patented ‘tunnel’ concept, ideal for applications where the airflow has to travel in a tunnel direction. Other models are available on request.
These products are typically used to cool analytical instruments,
small electronics enclosures and mini-refrigerators.

PowerCool Series
Available in 12 standard versions divided into 8 sizes, our PowerCool range delivers performance from 20 W to 193 W. All models are optimized for a variety of voltages, delta T and efficiency.
Moisture protected versions are optional (see Fans,).
We also provide a selection of temperature controllers. Typical applications include cooling electronics cabinets, analytical instruments, commercial refrigeration and food transportation boxes.

Specifications apply to ambient temperature 32°C and nominal Voltage. Tolerances ±10%

AA-060, AA-100, AA-150 and AA-200 available in Outdoor IP54 protected version.
Furthermore, IP54 protected AA-100, AA-150 and AA-200 also available in 48V DC design.




Ex = Example: At ambient 32°C and cooled space temperature 2°C (delta T = 30°C) the AA-100-24-22 (curve C) cools by 32% of its maximum effect, which gives Pc = 102 x 0.32 = 32.6 W (±10%)
