Concealed systems—an elegant solution for your interior

Integrate ventilation and air conditioning into walls and ceilings. We use ducted units and skim-in linear slot diffusers so the equipment stays hidden yet highly effective.

What are Concealed Systems?

Concealed systems are a strategic layout of engineering solutions, where ventilation, heat recovery, and air conditioning equipment are installed behind walls or above ceilings, while air distribution openings (diffusers) are skimmed into the surfaces. The result is functional comfort without visible technical elements.

Ducted air conditioners

A wide power range, easy to conceal above ceilings or in wall voids.

Skim-in linear slot diffusers

Flat, frameless diffusers that blend seamlessly with the ceiling surface and ensure aesthetic air distribution.

Key Advantages

  • Minimalism
    The interior remains uncluttered by visible equipment.
  • Comfort
    Even temperature and good air distribution without drafts.
  • Quiet operation
    Thanks to ducted solutions, noise is reduced.
  • Aesthetics
    Diffusers are nearly invisible—ideal for premium interiors.
  • Energy efficiency
    Project optimization helps reduce operating costs.
  • Custom design
    Solutions tailored to ceiling and wall structures.

Our Solutions

We offer a full service package: design, equipment, installation, and commissioning. We work with manufacturers and suppliers of ducted air conditioners and also install skim-in linear slot diffusers to achieve both aesthetics and functionality.

  • Project analysis – engineering analysis, CAD solutions, and coordination with the interior architect.
  • Selection and supply – we recommend the most suitable equipment for your needs.
  • Installation and integration – professional installation with no compromises on aesthetics.
  • Commissioning and tuning – we ensure optimal airflow and quiet operation.

Technical Aspects (Brief)

Below are the key technical criteria we assess when planning concealed systems:

  • Unit location: a free opening above the ceiling, service access through access panels.
  • Types of diffusers: linear slot diffusers, bar grilles, or micro-perforated solutions to match the desired aesthetics.
  • Noise control: sound insulation and vibration damping in the duct network.
  • Airflow management: balancing dampers, control modules, and zoned control.
