01Overview
Energy efficiency at
the core of every module.
Technogen HEROS air handling units are developed by the Technogen R&D team to deliver high-performance, energy-efficient and reliable air management for hygienic, comfort and industrial applications.
Specialised panel and body construction minimises thermal bridging, while the modular structure makes transport, installation, maintenance and dismantling straightforward.
Superior insulation
50 mm rock-wool insulated panels provide excellent thermal and acoustic insulation and long service life.
Wide range of filters
Panel, bag, compact, activated-carbon and HEPA filters for comfort, hygienic and clean environments.
Heat recovery systems
Rotary, plate and glycol-circuit exchangers for maximum efficiency in every application.
Advanced fans & motors
EC plug fans with VFD integration for precise airflow control at low noise.
Automation & control
Optional smart-building integration, remote monitoring and optimised performance.

02Anatomy
Built to be opened,
serviced and trusted.
Select a point on the unit to see how HEROS is put together.
50 mm rock-wool insulated panels, with panel and body construction designed to minimise thermal bridging and noise breakout.
Access doors and inspection windows give service teams direct, safe access to fans, filters and coils.
Clearly marked heating and cooling coil connections for fast, error-free installation on site.
Supply and extract openings with dampers, configured to the airflow arrangement of each project.
Units are built from modular sections on a base frame for easy transport, installation and dismantling.

04Heat recovery
Three ways to
recover energy.
HEROS integrates rotary, plate and glycol-circuit heat recovery — matched to each project's hygiene and efficiency requirements.
Rotary wheel
A slowly rotating heat wheel passes alternately through the extract and supply airstreams — storing energy from the outgoing air and releasing it into the incoming air.
Compact, with high recovery in a small footprint.
- 80%max. efficiency
- 40–80%humidity transfer
Humidity transfer is around 40% with a condensation rotor, up to 60% with silica-gel coating and up to 80% with zeolite coating. A sweeping cell turns return air back before it can mix with fresh air.
Well suited to
Plate exchanger
Thin plates form separate channels for the two airstreams, which exchange heat across the plate surfaces without mixing.
No moving parts and simple maintenance — a natural fit where airstream separation matters.
- 70%of the thermal load recovered
An optional bypass damper gives free cooling; a drain pan collects condensate on the exhaust side.
Well suited to
Glycol circuit
Separate coils in the extract and supply airstreams are linked by a pumped water–glycol loop that carries heat between them.
Supply and extract sections can be installed apart, with no contact between the airstreams.
Well suited to
