A new tool is available to speed up the process of selecting airflow regulators. We created the AlnorSELECT program for customer convenience and efficiency. The program allows the selection of VAV variable flow regulators (RAVAV and RAVAV-Q).
The main features of the AlnorSELECT program:
We invite you to use AlnorSELECT now. We believe that this innovative tool will contribute to the success of new projects. We will be happy to answer any questions and support you in the process of using the program.
A new model in the SlimAIR family is arriving!
In Q4 2023, we will introduce a new model of the HRU-SlimAIR-800 heat recovery unit. It is easy to decode this HRU model: the capacity will be 800 m3/h at 100 Pa. The design inherits the best features of the SlimAIR series, which include an EPP casing, a PET counter-flow heat exchanger with a very high recovery rate, and energy-efficient EC fans.
It is natural that the size has grown with the capacity: 386 x 1079 x 1397 cm. The HRU will also be available with a counter-flow energy recovery ventilator, intended for projects where moisture recovery is required. Traditionally for ALNOR air handling units, the controllers and sensors will connect wirelessly, but this time a version with wired controls will also be available.
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.
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),
heat recovery up to 95.2% (model HRU-SlimAIR-500),
built-in RH sensor.
These and other products for ventilation and heat recovery can be found in the PRODUCTS section
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.
Why is it worth choosing a SlimAIR recuperator?
Mounting in 3 positions (HRU-SlimAIR-250 and HRU-SlimAIR-350)
Slim and compact design
2 condensate drains
Access to filter replacement from two sides
CF constant flow system
Built-in pre-heater (only for HRU-SlimAIR-250-H unit)
Using a special mounting rack, installation can be done by one person
High thermal and acoustic insulation of the casing
