Pressurisation systems - tasks
Pressurisation systems have a central relevance in heating and cooling circuits and must essentially fulfil three fundamental tasks:
1. Maintaining the pressure within permissible limits at every point of the system, that is, the permissible working pressure must not be exceeded as well as maintaining a minimum pressure to prevent vacuum, cavitation and evaporation of the system liquid, e.g. in circuits with superheated water, solar systems
2. To prevent a negative pressure at the highest points of the installation in order to avoid the intrusion of air into the piping network
3. Compensation of volume fluctuations of the heating or cooling water due to temperature fluctuations.
4. Providing a water seal to prevent system-related water losses.
Careful calculation, commissioning and maintenance are the prerequisite for the correct functioning of the overall system.

Expansion Vessels For Heating & Chilled Water
V Intermediate Tank Applications
The V Intermediate tank protects the diaphragm / bladder of expansion vessels from impermissible temperature loads. According to DIN 4807 T3 and EN 13831, the
continuous temperature on the diaphragms must not exceed 70°C. In a cooling water systems, temperatures ≤ 0°C should be avoided.
In cooling circuits
If temperature is 0°C, we recommend to an intermediate tank
will be installed before the cooling vessel. To size the intermediate
tank volume (Vn) , consult Reflex calculation program.
In heating & solar systems
As a rule, heating & solar systems are operated at return
temperatures of ≤ 70°C. The installation of intermediate
tank is not necessary. In the case of older systems and
industrial plants, return temperatures > 70°C are sometimes
unavoidable.

V Intermediate Tank Calculation
• If the temperature is ≤ 0 ° C, before expansion vessel Reflex V essentials to set provisional capacity:
Vn = 0.005 x Vs
Vn = Nominal tank volume, Litres
Vs = Total volume of the system, Litres
% expansion
of the system
by volume
Meanwhile, at the point
RL connection tank
The total volume of the system Vs = 50 m³ = 50000 l
Max. system pressure = 10 bar
Flow Temperature = 105°C
Return Temperature = 80°C
Vcal = Vs x n
n = Expansion coefficient at an average temperature in the system (for example, 105/80°C, n = 0,038 cm. Reflex Pro software).
(If there is a possibility that the return temperature rises to a temperature in the supply line must be used the coefficient of expansion at max. temperature to
105 ° C, n = 0,047!)
Vcal = Vs x n = 50,000 * 0,038 = 1,900 litres
When the temperature in the return line 80 ° C provisional volume capacity Reflex V is equal to 8% of the volume expansion system,
Vn = 1900 * 0.08 = 152 litres
(If there is a possibility that the return temperature rises to a temperature in the supply pipe, the amount of the provisional Reflex V capacitance equals 20.5% of the
volume expansion system above for graph 105°C)
Select Reflex V 200/10 bar

Selection example
PSV= 3 bar
H = 13 m
Q = 40 kW (plates 90/70°C)
From the table:
With PSV = 3 bar, P0 = 1.5 bar
Vs= 1340 litres
Vn = 250 litres (for Vs max. 1360)
VPH = 1000 I (V buffer storage tank)
Selected:
1 x Reflex N 250/6 bar
1 x Lockshield cap valve
Calculate
Vs = 40 kW x 8.5 I/kW + 1000 = 1340 I
P0 ≥
(
13
+ 0.2 bar ( = 1.5 bar
10
Reflex recommendations:
• Select sufficiently high safety valve actuation pressure:
PSV ≥ P0 + 1.5 bar
• If possible, apply a 0.2 bar margin when calculating the gas
H [m]
input pressure: P0 ≥
+ 0.2 bar
10
• Due to the required supply pressure for the circulating pumps, select
a pre-set pressure of at least 1 bar for roof-mounted systems also: P0 ≥ 1 bar
• In a vented system in cold conditions, set the water-side filling or initial pressure at least 0.3 bar higher than the pre-set pressure:
Pa ≥ P0 + 0.3 bar
Approximate water content:
Radiators
Vs = Q [kW] x 13.5 I/kW
Panel-type radiators
Vs = Q [kW] x 8.5 I/kW
Chiller
Vs = Q [kW] x 18 I/kW
Theoretical principles
Expansion vessels (MAG) with a gas charge are functional without auxiliary energy and, for this
reason, are classified as static pressurisation systems. A gas blanket in the vessel generates
the pressure.
Water level and pressure in the gas chamber are interconnected (p x V = constant).
For this reason, it is not possible to utilise the entire nominal volume Vn for holding water.
Vn
The nominal volume is larger than the required water holding volume
Vn = (Ve + Vws) Pf + 1
Pf - P0
This is one reason for the preference of dynamic pressure maintaining systems in larger
systems and tight pressure ratios (Pf - P0).
Calculating the nominal volume
14
Vn = (Ve + Vws)
Pf + 1
Pf - P0

Bladder type pressure vessels manufactured and approved according to

Surge Vessel
Reflex pressure vessels , with interchangeable bladder, destined for the
anti-hammer protection in pumping systems. The liquid is contained
within the rubber bladder while the air (nitrogen) is trapped in the space
between the outside of the bladder and the wall of the vessel. Therefor
the liquid is not in contact with the steel walls of the vessel as it is
the case of open tanks with compressor. Since the water is contained in
minimum permeability butyl bladder, there is no air dissolution as it is
the case with compressed air.
Anti-hammer vessels offers protection to pipe network of pumping systems against fatigue and failure resulting from pump start-up / shutdown and sudden valve actuation.
Once installed, commissioned and set at the adequate pre-charge pressure, the pressure tank bladder will be able to dampen the water hammer transients of pressure waves resulting from opening or shutdown
of valves .

Selection according to peak volume flow Vs
When the nominal volume of the Refix unit has been selected, it must be checked in the case of water-carrying vessels whether the peak volume flow V s resulting from
the piping calculation according to DIN 1988 can be implemented on the Refix. If this is the case, the 8-33 litre vessel of the Refix DD unit may have to be replaced with
a 60 litre Refix DT 60 vessel to enable a higher flow rate. Alternatively, a Refix DD unit with an appropriately dimensioned T-piece may be used.

Pressure Vessels For Potable Water Applications
Refix Applications
Vessel on a booster set
Pressure vessels are installed on a pressure booster system in order to reduce pump starts and to eliminate pump starts at small draw-offs. This reduces pump wear
and extends pump life time.
Discharge side
Pressure vessel with flow-through function according to DIN 4807,
part 5. Inside epoxy coating in combination with butyl rubber bladder
ensures to fulfil the most strict German food stuff regulations such as
KTW-C (bladder) and KTW-A (inner lining). With the vessel mounted
on the discharge side of the booster system, the numbers of pump
starts are reduced and also pump starts at small draw-offs are totally
eliminated. Maintenance of the vessel can be done without shutting
off the water supply with the shown pipework.
To consumer
To consumer
Suction side
If supply pressure from the water mains is too low a pressure vessel
can advantageously be installed on the suction side of the booster
system. This will avoid cavitation in the pump, and also will eliminate
to risk of creating vacuum in the water mains by pump starts. This will
reduce the pump wear.

Pressure Vessels For Potable Water Applications
Reflex & Refix Applications
Applications
•In a solar system application the expansion vessel installed to the
flowpipe line therefore, the pump pressure needs to be considered
while setting the precharge gas P0.
•For the life time of the membrane we recommend to
install a Reflex V intermediate tank before the expansion
vessel if the retum flow is > 70°C
