Steel casing is covered with high-quality multilayer aluminium and zinc alloy to prevent corrosion. The casing is equipped with a switch to turn the ventilator off when the service panel is opened.
Washable MERV 6 air filters in exhaust and supply air streams. Optional supply: anti grease aluminum filter.
The unit incorporates an integrated automation and control system with following functions: • Operation mode switch. • Airflow balancing enabled by supply and exhaust fan independent speed adjustment from 0 to 100% (percentage is displayed on built in screen). • Automatic recovery core frost protection. • External control device connection (up to 5 at the same time).
The unit is equipped with supply and exhaust centrifugal fans with backward curved blades and build-in thermal overheating protection with automatic restart. The electric motors and impellers are dynamically balanced.
HEAT RECOVERY CORE
Aluminum cross-flow core ensures efficient heat recovery. Enthalpic core provides both heat&humidity recovery. For enthalpic core no drain required.
Blauberg ERV-D and HRV-D: Forced-air and exhaust fans with heat recovery (heat recovery ventilator), and fans with energy recovery (energy recovery ventilation)
Whole house fresh air systems provide a healthy and comfortable microclimate, as well as solve the problem of lack of fresh air, dust entering the room, and other harmful substances.
ERV-D and HRV-D installations will make housing even more energy efficient. Thanks to the technology of recovery, they will retain heat or coolness in the rooms. In the cold season, warm exhaust air in the recuperator transfers some of its heat to the supply air, and in the heat, the cooled exhaust air transfers part of the cold to the supply air.
The Blauberg HRV-D models are equipped with a plate-type countercurrent aluminum recuperator (aluminum cross-flow core), and the Blauberg ERV D are equipped with an enthalpy recuperator (enthalpic core) that prevents condensation from occurring during installation operation.
In these PVU for the house (house air exchanger) reliable German electric motors are installed. The ERV-D and HRV-D modifications are equipped with AC motors, while the ERV EC-D and HRV EC-D models use high-performance electron-switched (EC) engines, which are characterized by high performance and efficiency up to 90%.
Installation of this fan for your apartment (apartment ventilator) is quite simple and quick. The small height of the case allows you to place the installation in a limited space, for example, under a suspended ceiling.
