A twin-storage system with a cost-effective and compact solution, so it is possible to minimize space and installation costs.

The system consists of two units, two cylindrical tanks acting as one storage tanks: on top, a heating buffer tank with a pipe coil (TRX) for rapid production of hot water (100-300 liters). The lower unit is a buffer tank (AC), whose capacity can be selected according to requirements, in 30, 50 or 90 liter versions. A special feature of this model is that the tanks can be rotated relative to each other. The tanks have hard PU thermal insulation.

The unit is suitable for use as a heat pump or other low temperature heat source for heating water. The bottom buffer tank is used to increase the amount of water in the heating medium (e.g. heat pump defrosting) or can also be used as a hydraulic changeover. The tanks can be connected to an electric heater, which can be used as a backup or auxiliary heater.

The corrugated DHW coil is made of AISI 316L stainless steel, while the tanks are made of S235JR EN10025 quality carbon steel plate.

Properties:

The maximum allowable working pressure of the tanks: 6 bar
The maximum working temperature under pressure of the tanks: 95°C

Capacity:
Upper buffer tank (TRX): 100, 160, 200, 300 litres
Lower buffer tank (AC): 30, 50, 90 litres
