Regumaq X-25 fresh water station, heat exchanger copper brazed with Sealix® protective layer

Electronically controlled product assembly with heat exchanger for the hygienic heating of potable water according to the continuous flow principle. The potable water is heated at the moment it is needed: Just in time. For connection to the buffer storage cylinder. Depending on the temperature and the volume flow on the potable water side, the circulation pump on the primary side is speed-controlled.

The electronic control consists of a controller box inside the station with freely accessible control and display area.

The plate heat exchanger meets the requirements of the European Pressure Equipment Directive (PED). Due to the turbulent flow guidance, a good self-cleaning effect is achieved and thus contamination is prevented.

The plate heat exchanger can be flushed using the fill and drain cocks integrated in the primary and secondary circuit. The potable water circuit is protected by a 10 bar safety valve. The fittings of the heat exchanger system have flat sealing connections, are ready mounted on a support plate and tested for leaks.

The controller is fully wired with the internal components and designed for quick and easy commissioning.

- Number of heat exchanger plates: 46
- Discharge capacity: 1 - 25 l/min., depending on the set potable water temperature and the existing buffer storage cylinder temperature
- Connections: G 1 flat sealing for connection to the buffer storage cylinder and potable water circuit, all internal screw connections G ¾ and G 1 flat sealing
