When space is tight but performance is non-negotiable, Systemair’s Topvex TR and Topvex FR air handling units deliver. Designed with compact footprints and high-efficiency rotary heat exchangers, these energy recovery ventilators bring flexibility, comfort, and reliability to modern building projects—whether new construction or retrofit.
Topvex TR: Slim Powerhouse
The Topvex TR series is all about making high performance fit into tight spaces. With a design slim enough to pass through a standard 900 mm door opening, it’s a smart choice for buildings where installation space is limited.
Why engineers and contractors choose Topvex TR:
Compact design – Small footprint makes it ideal for retrofits and space-restricted installations.
Quiet operation – Low sound levels make it suitable for offices, hospitals, and shopping centers.
High efficiency – Rotary heat exchanger achieves over 80% heat recovery (dry, EN308). Optional sorption rotor improves comfort by recovering moisture and reducing cooling demand.
Flexible control – Supports both CAV (constant air volume) and VAV (variable air volume) systems.
Versatile installation – Available for indoor or outdoor applications.
BMS-ready – Integrates with common protocols like BACnet.
Plug & Play – Pre-programmed, factory-tested, and ready to install.
Easy maintenance – Components designed for quick service and long-term reliability.
Peace of mind – Backed by a 3-year limited warranty.
Topvex FR: Flat and Flexible
The Topvex FR series takes compact design one step further with a low-profile, flat construction perfect for ceiling spaces, corridors, and other challenging installation areas. Despite its slim build, it delivers exceptional efficiency and quiet operation.
What makes Topvex FR stand out:
Low-profile design – Perfect for suspended ceilings, corridors, or other tight installations.
Dual rotor heat exchangers – Exceptional energy efficiency with airflow capacities from 300 to 3,800 CFM.
Quiet performance – Double-insulated casing (30 mm panels, 50 mm hatches) keeps sound levels low.
Durable build – Magnesium Zinc (MgZn) casing with C5 corrosion resistance for long service life.
BMS integration – Easy connection via RJ-45 quick connector, external HMI, or ethernet for BACnet communication.
Green Ventilation – High efficiency with low SFP values, ensuring sustainable performance.
Service-friendly – Easy filter changes and maintenance access.
Warranty – Protected with a 3-year limited warranty.
One Solution, Two Smart Options
Whether you need a slim unit that slides through standard doorways (TR) or a flat unit for ceiling-mounted applications (FR), the Topvex series gives engineers and contractors high-efficiency air handling in the most compact designs available. Both are quiet, easy to service, BMS-ready, and backed by Systemair’s commitment to long-term performance.
