Kubix HRV




The Kubix™ HRV is the ideal choice for condominiums, apartments and other limited space applications that require up to 70 cfm of continuous ventilation.


With its compact size and 4-inch vertical ports, it can be installed in small spaces such as a closet or mechanical room above a hot water tank.

HRV and ERV - Why choose a HRV (Heat Recovery Ventilator)

A heat recovery ventilator system (HRV) is ideal for homes located in colder climates,

where there is excess moisture during heating season, since the unit allows to get rid of it.

A HRV system supplies continuous fresh air from outside in the house.

The heat recovery core of the unit transfers a portion of heat in the stale air being exhausted

to the fresh incoming air from outside before being distributed throughout the house.

The result is a continuous supply of fresh air, without unpleasant drafts,

and increased comfort for the home occupants.
