Modular Heat Pump Chiller Selection Questions
Where does a two-pipe system fit best?
A two-pipe system suits buildings whose connected zones can share a heating or cooling mode. It supplies hot water in heating mode and chilled water in cooling mode.
Can it be used in a boiler upgrade?
Yes. It can provide electric hydronic heating and chilled-water cooling with suitable terminals. An existing boiler can remain as supplementary or backup heat in the system design.
How do I choose the capacity for my building?
Use the building’s heating and cooling loads and required water temperatures to select the unit capacity and number of modules.
What should I send to start a project discussion?
Share the location, building use and the capacity you are considering. EXINDA can help compare configurations and provide the technical package for the next design step.
