Cascadetechnology–highefficiencyupto80°CTheuseofcascadetechnologyallowsthesystemtoworkveryefficiently over a wide temperature range right up to 80°C.Thehighesttemperatureproducedisthatwhichisrequiredbytheunitsduringoperationandthisensuresthatextraenergyisnotconsumedbeyondtheneedatthetime.

QuickheatuptimeThecombinationofheatpumpandcascadetechnologyallowsfor rapid heat up times, not only in terms of space heatingbut also for hot water – this can be particularly important inapplications, such as fitness centres, where spaces with lowheating demand are counter-balanced by spaces with highpeak demand. The heat from one area can be recovered,instead of releasing it to the outside air, and can be‘reused’forheatingorhotwaterproductionthusreducingtheheatuptimeandsoloweringoperatingcosts.

ReducethedevelopmentandexecutiontimeofyourprojectBy making use of our selection and dimensioning tools, it iseasy to design a single solution for heating, cooling and hotwater. Our advanced piping design and the elimination ofexhaust systemsallows foreasy integration intoanybuildingthussavingoninstallationtimeandaddingvaluetotheproject.

Quickinstallation!Our systems are dispatched from the factory with all thehydraulic components pre-fitted and ready to be connectedto the external piping. This makes them quicker and easierto install and so saves you time and the need for on-siteconfiguration,especiallywhenmultipleelementsareinvolved.Installinghotwater tanksontopof thesystem’s indoorunitsusingourplug-and-playfunctionalitycansaveadditionaltimeandtheeliminationoftheneedforachimneyorotherexhaustfittingavoidsadditionalwork.
