Accessories
Danfoss AVE expansion unit for pressure relief.
For systems, on which you want to avoid to have to establish
a discharge pipe, which extends from the water heater safety
valve and terminates at floor level, or is piped directly into
the floor drain, an AVE expansion unit is available as optional
equipment.
(AVE expansion unit must not be used on systems with DHW
recirculation).
