Lowara Break Tank Booster Sets
Description
Presfix range of pressurisation equipment, Microprocessor Single and twin pump units
Sealed system benefits:
In today’s demanding environment nearly all heating and chilled water circulating systems are
designed to operate in sealed networks.
The main benefits over previous systems which used feed and expansion tanks to accommodate
expanded water are many, large volumes of water are no longer required to be stored at the top
of the building. Expansion vessels can now be used in place of the storage tanks and these can
be placed anywhere in the building, usually in the basement where the weight is not such a problem.
The Feed and expansion tank being open to atmosphere allowed water to evaporate making
unnecessary demands on this precious resource.
Sealed systems reduce corrosion to an absolute minimum by sealing the system content from
atmosphere, and only adding fresh water to replace loses through leakage.
Sealed systems also offer the possibility of operating at higher temperatures if required
(Max 120°C) which permits lower circulation rates, smaller pumps and reduced pipe work
dimension with obvious cost savings.
These units are designed to replace water that has been lost through system leakage and to maintain the system design fill pressure in sealed heating and chilled water systems in accordance with BS7074 parts 1, 2 and 3. & EN12828
All Presfix units provide safety circuits locking out the boiler / chiller in the advent of high/ low pressures occurring.
Expanded water is accommodated in membrane vessel/s that are supplied separately and normally installed alongside the Presfix unit.
Presfix Beta Mk2 “dual” pressurisation sets bring the benefits of managing two independent systems
from a single unit
All Presfix Beta Dual system units are supplied as two pump sets and are available in three ranges,
2.8 bar, 5.5 bar and 8.0 bar fill pressures.
Presfix Beta MK2 pressurisation sets are available as single or twin pump units, and available
All Presfix Beta Dual system units are supplied as two pump sets and are also available in three ranges, 2.8 bar, 5.5 bar and 8.0 bar fill pressures.
Mini Presfix pressurisation sets are available as single or twin pump units, and are available
In two ranges, 2.8 bar and 5.5 bar fill pressures.
Micro Presfix pressurisation sets are available as single or twin pump units and have a maximum
fill pressure of 4 bar.
