7.1.2 Neutralising system no. 1606
The neutralising system no. 1606 comprises a plastic
casing with a chamber to hold the neutralising granulate,
a back-up area for the neutralised condensate and a
level-controlled condensate pump with a head of
approx. 2.0 m. No. 1606 enables the neutralisation of
condensate volumes from systems with up to approx.
850 kW rated output. The neutralising system no. 1606
is equipped with a stand-alone 230 V power supply.

Condensate pump
The amount of condensate determines the head of the
condensate pump.
The graph shows the heat of the neutralising system
no. 1606 subject to the pump rate.

7.1.3 Condensate lifting system no. 1620
The condensate lifting system no. 1620 was designed for
installation inside condensing boilers where corrosive
condensate according to the DWA Code of Practice
ATV-DVWK-A 25 is generated. The materials used in the
system permit the routing of condensate with a pH value
2.4 without any problem. For oil or gas condensing
boilers with an output > 200 kW, install the lifting system
downstream of the neutralising system.
The drive unit can be reversed on top of the tank and
thereby enables a variable supply and drain
arrangement.
The fully wired lifting system is equipped with a
standard alarm contact (NC/NO) for connection to a
condensing boiler or to an alarm controller.
