QV HR150 MVHR

Product Part Number

QV-HR150

Product Overview

The Quiet-Vent QV-HR150 is a compact mechanical ventilation with heat recovery unit suitable for homes of up to 130 m².

Manufactured using lightweight, sound-absorbing EPP construction with a protective metal outer cover, the unit provides a durable and exceptionally quiet ventilation solution. Its flexible design allows it to be installed on either the floor or ceiling, making it suitable for a wide range of property layouts and installation requirements.

The QV-HR150 delivers an airflow rate of 150 m³/h at 100 Pa and features an internal humidity sensor, touchscreen controller, fully adjustable fan speeds and automatic boost functionality.

An enthalpy heat exchanger provides heat recovery efficiency of up to 80% while transferring both heat and moisture between the outgoing and incoming air streams. This removes the requirement for a condensate drain under normal operating conditions.

The unit also includes a 100% summer bypass, low-energy EC motors and interactive Wi-Fi app control.

Construction

The QV-HR150 is manufactured using expanded polypropylene, commonly known as EPP, with a protective metal outer cover.

EPP is lightweight, impact-resistant and thermally insulating. Its sound-absorbing properties also help minimise operational noise and make it an effective construction material for MVHR units.

Motors

The unit is fitted with modern, backward-curved EC fan motors. These motors provide efficient, reliable and low-energy operation while allowing the supply and extract airflow rates to be independently adjusted.

Filtration

The QV-HR150 is supplied with two replaceable filters for the incoming and extracted air streams. The filters are positioned for straightforward inspection and replacement during routine maintenance.

Summer Bypass

A 100% summer bypass is included to prevent the incoming air from passing through the heat exchanger when heat recovery is not required.

The bypass is controlled through the digital controller and can help reduce unwanted heat transfer during warmer weather.

Low-Noise Operation

The airtight, aerodynamic and sound-absorbing construction helps minimise operational noise. Carefully balanced EC fans and the insulated EPP body allow the unit to provide effective ventilation with low sound levels.

Enthalpy Heat Exchanger

The QV-HR150 features a highly efficient enthalpy heat exchanger with heat recovery efficiency of up to 80%.

The exchanger transfers both heat and moisture between the incoming and outgoing air streams, helping maintain a comfortable indoor environment. Its enthalpy construction means that a condensate drain is not normally required.

Frost Protection

Intelligent frost protection is managed through the digital controller, helping protect the heat exchanger and maintain reliable operation during colder conditions.

Installation Orientation

The QV-HR150 can be installed on either the floor or ceiling. Integrated mounting feet are supplied to support secure installation.
