Wall mounted air conditioning is the most popular type of air conditioning system

 

Wall mounted air conditioning is the most popular type of air conditioning system. Versatile and easy to install, most wall air conditioning units have a filter which destroys funghi, collects duct in the air, bacteria and viruses which provides healthy clean air for the occupants. Modern wall air conditioning units have Innovative inverter compressor designs and the ozone friendly R410A and R32 refrigerants combined with low noise air movement fan arrangement. The result is a quiet, high performance cooling and heating system, with advanced electronic controls for maximum comfort, controllable and energy efficient.


 

Designed to give the greatest possible safety, performance and reliability even in the most demanding industrial and commercial applications

 

Designed to give the greatest possible safety, performance and reliability even in the most demanding industrial and commercial applications. Housed within the high-grade steel bodies and sickle bladed fans, designed to maximise airflow and pressure, which are driven by aluminium motors that keep weight to a minimum. Ideal for ventilation, extraction and fresh air supply as well as dust and fume extraction. Available in standard and explosion proof 110V and 240V~50Hz.
