MENRED S5 Energy Recovery Ventilator (ERV)

Air Quality Control

Application

50-Apartment Residential Project | London, UK

Characteristics

1. Energy Recovery Ventilation for 50 Apartments

The London residential project covers 50 apartments, with one MENRED S5 Energy Recovery Ventilator installed in each dwelling. This apartment-by-apartment configuration provides a repeatable residential ERV solution while allowing every apartment to operate with its own dedicated ventilation unit.

2. Rated Airflow for Ducted Apartment Ventilation

The S5 provides a rated airflow of 350 m³/h and a maximum airflow of 400 m³/h. These figures describe the product capability of the MENRED S5 and support its use in ducted apartment ventilation. The commissioned airflow used in the London apartments has not yet been provided.

3. H11 and G4 Air Filtration

The S5 uses an H11 filter on the fresh-air side and a G4 coarse filter on the return-air side. According to the S5 product specification, the filtration system provides 99% PM2.5 filtration efficiency, helping reduce the entry of fine airborne particles through the mechanical fresh-air supply.

4. Enthalpy Energy Recovery

A non-porous membrane energy recovery core transfers heat and moisture between the incoming and outgoing air streams without mixing the two airflows. Published S5 product data states heating and cooling enthalpy exchange efficiencies of 70.4% and 58.7% respectively. These are product specifications rather than measured London project results.

5. Slim Ceiling-Mounted Installation

With a 230 mm slim body, the S5 is designed for ceiling-mounted, ducted installation. In this project, one unit is installed above the ceiling in each apartment, helping integrate the ventilation equipment into the residential interior while retaining a dedicated system for every dwelling.

6. Air-Quality Control Capability

Air-quality control is included in the confirmed project solution. The S5 supports RS485 integration and compatibility with PM2.5 and CO₂ monitoring and control. However, the controller model, sensor model and actual control sequence used in the London apartments have not been confirmed.

7. Twin Inverter Fans and Adjustable Static Pressure

The S5 uses twin inverter fans for the supply- and exhaust-air paths and provides adjustable external static pressure. These product capabilities support adaptation to different duct layouts, although the actual pressure settings and duct resistance for this project should only be added after commissioning data is available.

More about the project

This residential energy recovery ventilation project is located in London, UK, and covers 50 apartments. One ceiling-mounted MENRED S5 Energy Recovery Ventilator is installed in each dwelling, creating an apartment-by-apartment ventilation arrangement across the development.

The S5 combines filtered outdoor-air supply, extract-air removal and enthalpy energy recovery in a ducted unit. Its published product specifications include a rated airflow of 350 m³/h, H11 filtration on the fresh-air side, G4 coarse filtration on the return-air side and 99% PM2.5 filtration efficiency. A non-porous membrane energy recovery core transfers heat and moisture between the two air streams while keeping the incoming and outgoing air physically separated.

The confirmed solution also includes air-quality control. The S5 platform supports RS485 connectivity and compatibility with PM2.5 and CO₂ monitoring, allowing the ventilation system to be integrated with an appropriate controller and air-quality sensor. The exact controller and sensor models used in this project are not currently disclosed.

With one S5 ERV assigned to every apartment, the project demonstrates a repeatable ceiling-mounted ERV solution for multi-unit residential buildings. Project-specific commissioned airflow, control settings, acoustic results and measured indoor-air-quality performance should be added only after they have been verified.
