If condensate forming on the air supply collector is A problematic it must be insulated so that it is steamtight Because the flue gases condense in the discharge system condensed water develops and must be discharged As a rule of thumb we anticipate a maximum of 1 litre of condensed water per m of natural gas consumed In practice this amounts to approx 5 litre of condensate per hour for the Quinta Pro 45 approx 7 5 litre of condensate per hour for the Quinta Pro 65 approx 10 litre of condensate per hour for the Quinta Pro 90 approx 12 5 litre of condensate per hour for the Quinta Pro 115 v v v vw 9 Exploded view 9 1 Exploded view 1021 1019 1022 1024 1021 1022 1023 5 1015 1021 1018 1022 1019 T003303 B T003424 A Wares Descipon P9 Hoot Setofmanppesta i Hoor Setofmainpipes 1003 M Hoor Setofmainpipes 1002 Set of main pipes 65 4 Set of main pipes 65 3 Set of main pipes 65 2 Low loss header DN 65 Boiler side DN 65 Installation side DN 100 Low loss header DN 100 Boiler side DN 100 Installation side DN 125 Gas supply pipe DN 65 Gas supply pipe DN 50 Elbow DN 65 Elbow DN 100 Gas filter DN 65 Gas filter DN 50 Connecting flanges DN 100 Connecting flanges DN 125 Blind flange DI
11. boilers This can be made possible by means of a cascade system In a cascade configuration heating boilers are connected hydraulically If the heat demand increases or decreases boilers are switched on or off respectively If using a Remeha multiple boiler controller or a quality building management system It is then important to determine the ideal number of boilers for the cascade The following factors need to be taken into account when deciding on the number of boilers ww Investment When boilers are split up the investment costs boiler cost including installation fittings pipe work pumps and control equipment can work out lower or higher However this depends to a large extent on the situation Reliability Reliability increases with the number of boilers Research has shown that reliability is already optimum for systems with four boilers in a cascade Efficiency There is no appreciable difference in terms of efficiency between several small or one or two larger boilers Maintenance and faults There is a greater overall risk of faults in a system with several boilers A larger group of engineers can service and maintain smaller boilers Configuration The lightweight and compact design means that you have more flexibility when siting the boilers Very little floor space is required and there is minimum load on the floor Adjustment When using several boilers and modulating control the heat output offered
12. circuit and the system circuit using a low loss header This means that a widely varying volume flow on the system side hardly influences the volume flow on the boiler side at all This also applies in reverse a widely varying volume flow on the boiler side hardly influences the volume flow on the system side at all Controlling several different groups hydraulically is therefore significantly easier as they do not or barely influence each other This creates better overall operating conditions for the system Use the iSense Pro for up to 6 boilers or the iSense in combination with the Celcia MC4 for a maximum of 4 boilers 3 Remeha cascade systems 3 1 3 2 General In order to make it as simple as possible to create a cascade configuration our product range has included complete cascade systems for years The compact design of the boilers combined with the smart gas and water connection technology of the cascade system makes it possible to install a high heat output in a small area For example using six Quinta Pro 115 boilers only 3 8 m approx including low loss header wall width is required for 642 kW 60 80 C The cascade systems can be divided into 3 main groups 2to 6 boilers in a linear configuration wall mounted 2to 6 boilers in a linear configuration mounted on a free standing frame gt 3to 6 boilers in a back to back configuration mounted on a free standing frame o Please contact us for differe
