BERETTA SC ACS 160 E - 225 E LOW ENERGY
The SC ACS 160 E - 225 E is a modern domestic hot water mixer that can use the heat accumulated in a storage cylin-
der to produce high volumes of domestic hot water. The unit incorporates an AISI 316 stainless steel brazed plate heat
exchanger.
The unit is controlled by an electric panel complete with a controller for the control and management of the functions of
all system components. The unit also permits the manual operation of all system components.
The heat exchanger’s PRIMARY CIRCUIT comprises:
- A 3-way mixer valve for stabilising the temperature of incoming hot water
- 2 modulating pumps with 0-10 V control, installed in parallel
- A warning system with buzzer and LED indicator to warn of malfunctions in either of the 2 pumps
- A return line diverter valve that controls two separate storage cylinders or one storage cylinder with stratification control.
The heat exchanger’s SECONDARY CIRCUIT, which delivers the domestic hot water comprises:
- An electronic meter for DHW temperature and flow control.
- A variable speed circulation pump.
