A hot-box can be described as a seperate boiler unit. The hot-box is connected to a cold water cleaner and in this way you obtain the same features as a hot water cleaner. The advantage is, that you only need to connect the hot-box, when you need hot water. The boiler is suited for 21litres of water per minute and has an effect of 88 kW. A diesel tank is integrated. Hot-boxes with more boilers and for high pressure cleaners up to 500 bar are produced upon request.
