Monolink General Information

Terminal units connection system

Albion’s Monolink is an innovative and ultra compact valve arrangement that minimizes the time and space required to connect system terminal units to distribution pipe.All the components required for flushing and commissioning the system can be combined in a single assembly that will fit in the tightest corners. Albion’s Monolink assembly incorporates an isolation valve with integral strainer, a drain point, an inbuilt special bypass valve and balancing valve, static or dynamic. Thanks to the isolation valve fitted on the flow side, it is possible to clean and service the strainer without having to drain down the whole system.Only four connections are required and, because the connections are simple union joints, the whole assembly can be adjusted on site for maximum convenience and easy accessibility in the space available.

In every hydronic system for heating or cooling there are terminal units of different styles, such as fan coils, air handlers, radiant ceiling to heat or cool spaces in the building.For accurate functioning of the system each terminal unit needs to be isolated, strained, vented and balanced.Assembling different valves to achieve these features could be rather complicated, due to the large number of components and couplings used to create the connection.The same procedure is requested for all the terminal units existing in the system.It is evident that such operations could take hundreds of working hours, involve high labour costs and lead to risks for possible joint leakage. None the less it requires high logistic organisation to make sure each valve and fitting for the connection is available on site.Albion’s Monolink is a preassembled factory tested valve arrangement, which combines in a unique item all the components needed for a terminal end unit, such as strainer, bypass valve, balancing valve and drain cock, with no need of assembly on site.

Monolink Operation

Flushing and chemical cleaning

Monolink contains all the features required to flush the sys-tem in accordance with Bsria Application Guide AG 1/2001 Pre-Commission Cleaning of Pipework Systems.The flushing procedure should be agreed in advance with the appointed pre-commission cleaning specialist.For most situations, it is envisaged that flushing will take place in three stages.Stage 1 will be a flush and, where appropriate, chemical clean of the main system with terminal unit isolated as shown in picture below.Please note that strainer basket must be removed before commencing the stage 1 flush.Stage 2 and stage 3 will take place after the main system has been cleaned and chemically treated. Clean water from the system will be forward flushed through the units, then reverse flushed in order to dislodge any material trapped in the terminal unit or control valve.Stage 4 after flushing and chemical cleaning, Albion’s Monolink is ready for commissioning and operation in standard position.
