- a high performance, heavy duty, mobile unit featuing both heating and cooling. Don't confuse this with the cheaper units offered in the DIY sheds - this is a heavy duty (it weighs 41kg!) unit built around superb quality TOSHIBA componants to provide many years of service. It is perfect for commercial use but is of course subject to the same limitations as any portable system in that you still need to have an external venting pipe and the noise levels are higher than for split systems but if you need rapid, instand heating or cooling then this is the system for you. Supplied with a window mounting outlet, this is suitable for larger rooms as it has an extremely high air throughput of over 500m3/hour. Supplied with full digital remote control enabling you you set and forget the temperature and programme the on off times as required.find out more...
