Safety notes:
The safety notes are to be observed.
Installation, initial operation, maintenance and re-
pairs have to be carried out by authorised and
qualified trade persons.
Application:
Oventrop high-capacity plate heat exchanger with
connection fitting, a modular complement to the
boiler connection systems "Regumat" DN 25 for
use in unsealed type surface heating systems or in
existing installations with system related oxygen
input.
Due to the heat transmission working on the in-
verse flow principle, an extremely high power
transfer is achieved.
The heat exchanger is available in two capacities:
14 kW/28 kW
Material: stainless steel 1.4401, copper brazed

The performance date are determined by the fixed
given values in the primary circuit (70/50°C) and
secondary circuit (40/50°C).
Function:
The heat exchanger prevents the penetration of
oxygen from the surface heating circuit into the
boiler circuit which could cause damage to ferrous
system components due to oxygen corrosion.
In reverse, a penetration of any corrosion products
(rust pulp) from the boiler circuit into the surface
heating circuit is also prevented.
Due to turbulent flow conditions, an excellent self-
cleaning effect is produced.

Assembly note:
a. Connection to the pipework
Connect heat exchanger "Regumat" with insula-
tion to the existing pipework - distance between
pipe centres 125 mm.
Tailpipe sets and couplings are to be ordered sepa -
rately

cording to DIN EN 12828, the consuming circuit
must be protected against an excess working
pressure by a safety valve. Safety groups for the
heat exchanger "Regumat" are to be ordered sep-
arately
c. Connection to the pipework with two pump
groups "Regumat" for the supply of the consuming
circuit and the boiler circuit and the hydronic sep-
aration of the boiler and heating circuit (example
2): Similar to point b, the boiler circuit is additional-
ly supplied by another pump group "Regumat".
Connection set for the connection of the heat ex-
changer "Regumat" to a pump group "Regumat"
on the boiler side to be ordered separately
