Expansion vessels do have a number of important functions to fulfil: To restrict the pressure fluctuation of the system within certain limits (otherwise loss of water may occur via a responding safety relief valve) To prevent a negative pressure at the highest points of the installation in order to avoid the intrusion of air into the piping network To avoid steam building or the evaporation of the system liquid, e.g. in circuits with superheated water, solar systems To avoid cavitation inside pumps and fittings (preventing pump damage) To keep a water reserve in order to avoid a pressure drop caused by occasional losses of volume, e.g. due to venting after the initial starting up of the system To compensate for the variations of volume due to the changes in temperature of the system liquid

V Intermediate Tank Applications

V Intermediate tank protect the diaphragms 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 heating & solar systemsAs a rule, heating & solar systems are operated at returntemperatures of ≤ 70°C. The installation of intermediatetank is not necessary. In the case of older systems andindustrial plants, return temperatures > 70°C are sometimesunavoidable.

In cooling circuits If temperature is 0°C, we recommend to an intermediate tankwill be installed before the cooling vessel. To size the intermediatetank volume (Vn) , consult Reflex calculation program.

In a solar system application the expansion vessel installed to the flow pipe 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 return flow is > 70°C.

Reflex recommendations:

Select sufficiently high safety valve actuation pressure: Psv ≥ P0 + 1.5 barIf possible, apply a 0.2 bar margin when calculating the gasinput pressure: P0 ≥ + 0.2 barDue to the required supply pressure for the circulating pumps, select an pre-setpressure of at least 1 bar for roof-mounted systems also: P0 ≥ 1 barIn a vented system in cold conditions, set the water-side filling or initial pressureat least 0.3 bar higher than the pre-set pressure: Pfil ≥ P0 + 0.3 bar

RefixRefix DD/DT Hygienic Pressure Vessels

The Refix DD/DT vessels continue to deliver unparalleled performance andpersistence, meeting all the tough requirements of the German DIN 4807part 5. The shell of the tank is made of heavy gauge steel and has epoxycoating from inside. The dual water connection for internal circulation delivered in various sizesranging from 1 1/4 up to DN 100. The butyl rubber bladder offers the lowestpermeability compared to any material used today.

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.

Refix DE Applications


DT vessel on a booster set - suction sidePressure 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). 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.

DE vessel on a booster setPressure 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.

DT vessel on a booster set - discharge sidePressure 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.

DT vessel on a booster set - suction and discharge sideInstallation of a pressure vessel on both sides of the pressure booster set can also be necessary. See explanation above. By using the DT pressure vessel according DIN 4807, part 5 there is a high grade of protection against contamination of the cold water supply mains. 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).
