The Silent range of Air Conditioners have been specifically designed for installation through the roof of motor homes, caravans and specialist vehicles through a 400 x 400mm aperture, or by replacing a standard roof light.  

By installing a rooftop Air Conditioner you will not lose valuable storage space needlessly taken up by other installation methods, and because warm air rises and cold air falls,  the roof top units benefit, thus helping to make them highly efficient.

Special Care has been taken to ensure low noise both inside and outside through a revolutionary dual noise reduction system.  Attention is also paid to the low consumption of these units.



The Silent models are designed for medium to large motorhomes and caravans. The 8400 has been designed for Caravans and Motorhomes ranging in length from 6.5  to 8 metres, this is due to its cooling capacity of 2.40 Kw (8.200BTU) making it ideal to this vehicle size.  

The ever popular Silent 7400h is ideal for vehicles ranging from 6-7 metres in length with it's cooling output capacity of 2.20 Kw (7.500BTU), with the Silent 5400h designed for vehicles from 5-6 metres such as single axle caravans due to its cooling capacity of 1.70 Kw (5.800 BTU)



Heating with a high-efficiency heat pump provides a heating capacity from 1.75 - 2.5Kw with a power consumption from just 0.69 - 0.98Kw (model dependent)

The heat pump is effective until the outside temperature drops to +0° C, after this point the heat capacity diminishes drastically.



By setting AUTO mode, the air conditioner automatically selects either the cooling or heating mode and a suitable ventilation speed to maintain the temperature selected.



All functions can be performed via the remote control which now includes a programmable timer



To protect against icing.



Removable so can be cleaned



Suitable for roofs with a thickness of 30 to 70mm
