Technical advantages

Minimum amount of heat-exchange surfaces made of metal or plastic

Possibility of using vessels made of plastic instead of high-grade steel

No continuous operation of the vacuum pump, plant operation is even possible without a vacuum pump.

Reduced effort for fluid circulation and control, which means much fewer fittings and simpler measurement and control systems

Modular design, simple and cheap plant components, low maintenance costs. Very high reliability thanks to self-regulation, thus lowering the risk of the mixing of dirty and clean water, highly tolerant towards changing parameters

Technically simple operation (no special staff training is necessary); Plant is fail-safe: i.e. high level of system security, no danger of explosion

Low temperature level of input energy (between 50°C and 100°C, it is possible to use waste heat and solar power)

Efficient energy use thanks to cascade principle·Exceptionally fault tolerant, i.e. the loss of one module only reduces the total capacity of the plant by the capacity of the failed module
