Efficiency and great appearance in one solution.

CWS-COMBI – an innovative air intake and exhaust unit for efficient forced ventilation where there is little installation space. Thanks to a unique design, fresh air is taken simultaneously with ejection of waste air and without cross-flow within a small space.

The unit is perfect for heat recovery systems where there is no room for traditional ventilation ductwork. It is made of durable galvanised steel and powder-coated in RAL9010 for a great finish. There is an integrated drip cap to protect the exterior wall from dirty weeps, and a mesh to fend off debris. The product is available in the RIGHT- and LEFT-HAND versions.

SlimAIR has received Passive House certification

 

SlimAIR has received Passive House Institiute certification!

When applying for projects that require Pasive House certification, you may want to consider our HRU-SlimAIR-250-H in the category Ventilation systems < 600 m3/h.

When building a house with low energy consumption, otherwise known as a passive house, it is necessary to use the highest quality components that will allow us to achieve high energy savings relative to conventional house design. One of the 3 pillars of passive houses is mechanical ventilation with heat recovery. Recuperation provides fresh and clean air, and thanks to the high efficiency of heat exchange - significantly reduces heating costs.

It was tested at 100% efficiency with the  maximum airflow of 242 m3/h. What’s also noteworthy: Dimensions of the unit are extremely flat with a height of 242 mm. 
As a result, the unit can be hidden in the dropped ceiling. Get to know the SlimAIR range of heat recovery units.

Meet the SlimAIR family of recuperators:

  • efficiency 250 / 350 and 500 m3/h,

  • only 242 mm in height (model HRU-SLIMAIR-250),

  • lightweight design - from 25 kg,
  • heat recovery up to 95.2% (model HRU-SlimAIR-500),

  • built-in RH sensor.

Wider selection of SlimAIR


A wider selection of SlimAIR heat recovery units is now available.

The new models are the HRU-SlimAIR-350 and HRU-SlimAIR-500, with capacities of 350 and 500 m3/h, respectively. Ceiling-mounted heat recovery units can be equipped with an enthalpy exchanger (moisture recovery) and a CF module (constant air flow). The maximum heat recovery for the HRU-SlimAIR-350 is up to 94%. The version with enthalpy exchanger (the HRU-SlimAIR-350E) is characterized by heat recovery up to 91% and moisture recovery up to 87%.

The heat recovery efficiency of HRU-SlimAIR-500 heat recovery units is up to 95.2%, and for the version with enthalpy exchanger (the HRU-SlimAIR-500E), up to 89% heat recovery and up to 85% moisture recovery.

Universal installation is a unique feature of SlimAIR heat recovery units: they can be wall-mounted horizontally, vertically, or suspended horizontally (HRU-SlimAIR-250 and HRU-SlimAIR-350). In the case of HRU-SlimAIR-500, this unit is designed to be either ceiling- or wall-mounted, vertically.

HRUs are equipped with pleated filters with increased filtration area, which generate low pressure drops. The filters are classified as ISO Coarse 70% according to ISO 16890. ISO ePM1 55% fine filters are also available.

Compact housing - MinistAIR fits

 

New version HRU-MinistAIR 

HRU-MinistAIR residential heat recovery units are a new version of a well recognized model, based on a completely new design. Airflows of 250 or 325 m3/h and self-supporting casing made of EPP, acting as thermal and acoustic insulation at the same time. Counter-flow heat exchangers, made of PET, are responsible for heat recovery and enthalpic exchangers (E) recover moisture. In addition, the built-in RH sensor will take care of moisture level in the building. Left and Right version, together with horizontal installation, will allow you to adapt the unit to almost each project. Moreover, 56 cm width will allow installation in narrow spaces or wardrobes.

Wireless communication is used, likewise other series, both for controllers and IAQ sensors. Control is possible also via a mobile application.

 

Key performance features:

  • Heat recovery: HRU-MinistAIR-250 - up to 96%, HRU-MinistAIR-325 - up to 95.5% 
  • Mounting in 3 configurations- wall-mounted: vertically, horizontally and standing on the floor 
  • Left-hand and right-hand units (mirror image of the connections) 
  • A horizontal model for both left and right configuration 
  • Two condensate drains. By designing the inclinations in EPP, excess water can flow freely to the drain connector
