Air Diffusers

Designed for high comfort.

Together with renowned designers and architects we have developed ceiling, wall, staircase and floor diffusers and grilles that are not only aesthetic design elements but also meet demanding ventilation and acoustic requirements.

Air-Water Systems

Air for the people - water for the loads.

Today, air-water systems are used in many modern buildings and, especially in office and administration buildings, offer energy-efficient solutions for the internal space ventilation and air conditioning.

There is a variety of installation possibilities for air-water systems, which means that, for almost every building, variants that meet the most demanding architectural requirements are available.

Fire and Smoke Protection

Tested and Certified Safety

Every person should be able to feel safe in the knowledge that the building they are entering or using and underground transport systems will not put them in danger or become a trap. For this reason, fire can never really be completely ruled out, not least due to human error.

The correct preventative measures and components can help to eliminate this risk and restrict the damage caused by fire. Fire safety components and systems help to minimize the risk of fire and prevent fire and smoke from spreading.

Ce Marking of TROX Fire Dampers

TROX fire dampers carry the CE marking in compliance with EN 15650. The CE marking ensures that TROX fire dampers can be used for all approved applications across the EU.

With the TROX Declaration of Performance and the operating and installation manual customers are given a complete documentation package which ensures that TROX fire dampers can be used safely.

Since the Construction Products Regulation (CPR) became effective on 1 July 2013, Declarations of Performance have replaced the previously used approval certificates or declarations of conformity. By providing the Declarations of Performance, TROX, as a manufacturer, ensures that its products conform to the data given in these documents.

Construction Products Regulation

The Construction Products Regulation aims at harmonizing the technical specifications for construction products. The TROX feature article “New Harmony for European Markets” explains what is special about the new regulation and uses examples to explain the most important facts and names.

How much air do you need?

Ventilation and air conditioning systems are called upon to adjust indoor air quality and the conditions for heating comfort and humidity in a room so as to comply with established stipulations (DIN EN 13779).

The priority of this observation is the indoor climate. To maintain the necessary air quality and enable economical operation of the system, all air flows of a system must be monitored and controlled. The air-distribution equipment is thus given an important task.

TROX is one of the world's leading manufacturers of these units. Our international success is based on 35 years of development and production experience of volume flow terminal units and related components.

Central Air Handling Units


With the X-CUBE compact TROX has created a ready-to-operate and pre-configured air handling unit that combines the excellent features of the X-CUBE in the smallest of spaces. These units handle volume flow rates of 600 to 6,000 m3/h and offer a heat recovery efficiency of over 80 % (dry, to EN 308), hence they are the ideal solution for small and midrange applications.

TROX offers nine different X-CUBE compact units with a choice of two different heat recovery systems.

Top performance, small size.

  • Volume flow rates of 600 to 6,000 m3/h.
  • Maximum energy efficiency.
  • Powerful EC fans also for high external differential pressures.
  • High level of hygiene (conforms to VDI 6022).
  • Heat recovery with heat wheel or counter flow plate heat exchanger.
  • Air filtration with TROX minipleat or NanoWave filters.
  • Weatherproof construction variant.
  • Ready-to-operate unit (plug and play).
  • Operating side can be changed at a later stage.
  • Integral, bus compatible control technology.
  • Advantages at a glance.
  • High energy efficiency.
  • Unparalleled hygiene.
  • Easy installation.
  • Safe maintenance.
  • Intuitive navigation.
  • Seamless integration into modern building management systems.
  • Made in Germany.



With the TROX X-CUBE, an air handling unit with unlimited configuration options, TROX sets a new standard in the AHU market and defines considerably higher levels of quality, performance, flexibility, reliability, energy efficiency, and hygiene. Compelling all down the line. TROX now offers everything from a single source: air handling units and components - ideally complementary to each other.

For even more energy efficiency and better quality with less coordination effort.

  • For the ventilation of rooms and entire buildings, for filtering, heating, and cooling the air, for heat recovery as well as for humidification and dehumidification, and for volume flow rates of up to 86,000 m3/h.
  • Flexible frame construction, completely covered externally by thermally insulated panels or doors.
  • Easy installation, maintenance and cleaning.
  • Significantly reduced wiring workload due to flexible control and regulation based on fieldbus technology.
  • Special hygiene construction variant according to AHU Guideline 01 (RLT-Richtlinie 01) for use in hospitals and laboratories; weatherproof construction variant for outdoor installation.
