MAKE UP LINE Substations
Make Up substations for secondary heating
circuits with heat load up to 8000 KW, and the
static height up to 60 mwc
Compact substations for water expansion control in heating installations
(secondary side), with atmospheric tank and automatic make / fill up functions
Designed for floor mounting
Description
Function
The Make Up system has the function to discharge
the soft water into an atmospheric tank via pressure
relief valve(s) if the heating circuit develops a
pressure value over the maximum set value or has
the function to fill up the heating installation circuit
via make up pump(s) if the pressure decreases
below the minimum set value. The volume of filling
up water or the leakage water from heating circuit
is automatically replaced in water tank via solenoid
valve.
Also, the system:
- is able to protect the pump in case of water
lack;
- can assure a sequential start of pumps;
- is able to stop functioning pumps in case of pipe
breaking;
- can make automate switching on the second
pump in case of failure function of the first;
- assures the permanent monitoring of the water
level in the atmospheric tank (minimum, normal
and maximum);
- assures the filtering of water.

Purpose
This system is suitable for maintaining the pressure
between an overpressure given by water dilatation
and an underpressure limit given by loses of water
from different reasons in secondary heating
circuit.
Installation
The MAKE UP LINE is a range of systems mounted
on the secondary side of district heating systems
or thermal plants with a maximum temperature of
115 oC and PN 6 / PN 10 in the flow circuit.

Construction
The construction is compact, simple and easy to
use. The pipes are corrosion protected through
galvanic treatment both on the inside and on the
outside. The components selection (size and type)
is made using a calculation method developed by
Schmidt-Bretten Technology, member of Danfoss
Group.
Specific advantages
- protection of the heating circuit at overpressure
- automatic control of pressure in heating circuit
- monitoring and remote control
- a unitary system, ready to be mounted in site, easy
to install for a minimal location site
- very good performances when coupling with
Schmidt heating substations

Main functions:
Specific restriction
- Maintains heating system pressure in very strict
limits;
- Protects the heating circuit against
overpressure;
- Fills up and makes up the heating circuit;
- Recovers the discharged soft water from the
heating system;
- Monitors the water leakage and, in case of pipe
breaking, stops the pumps;
- Monitors the water level in atmospheric tank
(minimum, normal and maximum);
- Fills up water tank;
- Protects pump in case of water lack;
- Communicates via standardized RS485 optional
modules
- The soft water available flow should be larger than
the necessary make up flow for heating circuit.
