Station domestic hot water


domestic hot water production stationAqualda is a group for the production of domestic hot water in an instant, and has a flow rate of 5 150 in liters per minute and this makes it particularly suitable for applications with high demand such as apartment buildings, sports centers, industries and process applications.

This system has been optimized for the combination with heat pumps and solar thermal systems: in fact, the heat exchanger ensures maximum flow with only 50 ° C instead of the 65 / 70 ° C used by similar systems.

Hygiene hot water is produced instantaneously always assured because, in this way you avoid the proliferation of bacteria caused by stagnation of water (eg legionella). Also provided is a treatment cycle programmable for thermal disinfection of the recirculation lines.

At the time of the request by the user, the hot water accumulates through the exchanger of Aqualda and transfers heat to the sanitary water without ever coming into contact with it.

This ensures absolute sanitary water hygiene and its immediate delivery.

Aqualda is equipped with a brazed plate heat exchanger of generous dimensions that guarantees water flow up to 150 liters per minute and, with cascade installation, up to 1200 l / min.

Aqualda is a compact station that can be installed on the wall or directly on the storage tank.

High flow rates with 50 ° discharge

Aqualda is ideal for solar thermal systems and heat pumps, thanks to the high surface plate heat exchanger.

With precise detection and immediate VFS sensor and the joint work of the modulating pump and the mixing valve, Aqualda ensures constant temperatures even at low flow rates.
