VENTI high efficiency residential HRUs

VENTI high efficiency residential HRUs


VENTI series residential heat recovery devices are ideal for large houses with 90% thermal efficiency and high capacities to meet your air flow needs up to 700 m3/h.

Our devices are designed to be plug and play, and equipped with advanced automatic control options, standard G4 filters, by-pass damper for free cooling, along with temperature and humidity sensors. In addition, you can change the directions of the air vents and provide the most suitable connection for you to meet your different assembly needs.


General Information

High efficiency heat exchange system with EC Fans

High efficiency hexagonal counter flow plastic plate heat exchangers offer up to 90% thermal efficiency. Our fans are self-motorized with energy saving EC motors and operate quietly. The metal casing is double walled, with 25mm insulation material in-between to ensure both high thermal performance and low noise levels.

Free-Cooling

On seasonal transitions (spring and autumn) when indoor and outdoor temperature differences are not significant, BSK Heat Recovery Units automatically switch to Free Cooling mode by opening the built-in bypass vent. The air will pass through this canal without going through the heat exchanger, so you can cool your house directly.

Humidity Control

Built-in humidity sensor can automatically set your BSK Heat Recovery Unit to Boost mode when a set level of humidity is reached in your house to quickly dissipate the moisture to prevent it building up. 

Defrost mode

We suggest that you equip a pre-heater for uses below 0 C to avoid freezing inside the unit, however to prevent this from happening when there is no heater attached, our devices automatically enter defrost mode when temperature requirements are not met. Defrost mode adjusts intake and exhaust air rates to prevent icing and keep the device temperature at a safe level. We strongly advise you to use a pre-heater for climate conditions below -10 C.

ModBus Compatible

Our units use ModBus protocol to connect and communicate with your building management system and report malfunctions or periodic maintenances. You can monitor and control your device through a computer or a central system.

Accessories

F7 filter


Our standard G4 filters offers good protection against dust and common particles, however you may need additional protection from pollens and other smaller particles especially if residents are allergic. We suggest the F7 grade pollen filters for such individuals.

Pre-heater

For subzero outside conditions, you should equip an electrical pre-heater to prevent ice forming inside the unit. This electrical pre-heater can connect to your BSK Heat Recovery Unit’s fresh air intake vent.

Water heater


If your house is already heated by hot water, you can equip duct type water coils to the supply air vent to further heat the incoming air for a precise control of temperature. For buildings without the option for a water heater, we also offer electrical heaters.

Silencer


We designed BSK Heat Recovery Units to be as quiet as possible; however you may need to further reduce the noise levels in some situations. You can add the duct type silencer or the flexible silencer for those tight spaces, to the supply vent and enjoy the silence.

Drainage siphon


Condensation inside the BSK Heat Recovery Unit is kept at a minimum but varying humidity and temperature levels may increase the precipitation. With this apparatus you can connect your unit to your existing water system and get rid of the water droplets hassle free.

CO2 Sensor

CO2 sensor allows automatic control for ventilation rate in crowded venues or houses with fireplaces. When the CO2 levels rise, your BSK Heat Recovery Unit increases ventilation rate to supply you with the best air quality.
