EcoSlim 900 - Commercial Ceiling Mounted MVHR Heat Recovery Ventilation Unit

EcoSlim 900 Commercial Ceiling MVHR Unit

The EcoSlim 900 is a slim commercial ceiling-mounted MVHR unit designed for offices, schools, retail spaces and commercial fit-out projects where efficient fresh air ventilation, heat recovery and compact installation are required.

This configurable version allows you to choose between left-hand access and right-hand access, helping contractors, consultants and facilities teams select the correct service orientation for the project. Choosing the right access side is important when planning filter changes, commissioning, maintenance and future inspection above a suspended ceiling.

With an ultra-slim 318 mm casing height, the EcoSlim 900 is well suited to commercial ceiling void installations where available service space is limited. It can be installed discreetly above suspended ceilings, helping keep ventilation equipment out of sight while maintaining access for servicing.

Commercial Heat Recovery Ventilation for Modern Buildings

The EcoSlim 900 provides balanced supply and extract ventilation for occupied commercial spaces. Stale indoor air is extracted while fresh, filtered outdoor air is supplied back into the building. Heat from the outgoing extract air is recovered through a durable polymer counter-flow heat exchanger before the air is discharged outside.

With heat recovery efficiency of up to 88%, the EcoSlim 900 helps reduce wasted heat while supporting better indoor air quality. This makes it suitable for workplaces, classrooms, meeting rooms and other commercial environments where comfort, energy efficiency and fresh air supply are important.

Choose Left or Right-Hand Access

The EcoSlim 900 is available with either left-hand or right-hand service access. This allows the unit to be selected around the practical layout of the ceiling void, including duct routes, walls, ceiling grids, lighting, cable trays and other building services.

• Left-hand access: choose this version when servicing and filter access are required from the left side.
• Right-hand access: choose this version when servicing and filter access are required from the right side.

Selecting the correct access orientation helps prevent maintenance issues after installation and makes routine filter changes easier for contractors and facilities teams.

Designed for Suspended Ceiling Installations

Commercial buildings often have limited space above suspended ceilings. The EcoSlim 900 has been designed for these conditions, offering a low-profile MVHR solution that can be integrated into compact ceiling voids without using valuable floor space or plantroom space.

This makes it a strong choice for office refurbishments, commercial interiors, education buildings and new-build fit-out schemes where a discreet but capable ventilation system is required.

High Pressure Performance for Commercial Ductwork

The EcoSlim 900 delivers airflow up to 1,030 m³/h and pressure up to 500 Pa, making it suitable for longer duct runs, multiple grilles and more complex commercial layouts.

Low-energy EC fans provide efficient, controllable and quiet operation, helping maintain continuous ventilation in occupied spaces without unnecessary running costs or excessive background noise.

BMS Integration with Modbus RTU

Built-in Modbus RTU allows the EcoSlim 900 to connect with compatible Building Management Systems. This supports smarter commercial ventilation control through monitoring, schedules and wider building management strategies.

For projects where energy use, air quality and system visibility matter, the EcoSlim 900 provides a practical ceiling-mounted MVHR solution with the control features expected in modern commercial buildings.
