Group BW

Description:

BW is composed of a pump group connected to a plate heat exchanger, whose purpose is to separate the primary circuit from the secondary. The unit can be installed into existing circuits which are already provided by a primary circuit. Then it will be sufficient to mount the unit into the existing heating circuit.The circuit temperatures can be checked, by means of the thermometers inside the handles of the ball valves.

The unit is supplied without circulator as standard. On request, a circulator, among those available on the market, having 180 mm in height and 1½" connections, can be mounted. The unit is provided with right flow, which can be easily changed and turned into left. It is particularly important for the circulators to be assembled in such way, because this enables the flow inside the exchanger an upstream course.
