New single pipe mini recuperation system

The ultra-compact new wall-mounted mini recuperator VL-50S2-E is designed for use in private homes, apartments, offices, or other small rooms where there is a lack of ventilation and no possibility to install a ducted recuperation system. For optimal ventilation, one unit is usually enough for rooms up to 12-40 m2.

  • Operates down to -22 ° C

  • New R32refrigerant

  • Energy efficiency class A ++/ A +

  • 3-year warranty

  • Exclusive design panel with hidden LEDdisplay

  • WiFifunction

  • Supplied with two filters: catechinand activated carbon

  • High speed processors

  • The indoor unit can be controlled by iOSor Android

Advantages of the mini recuperator VL-50S2-E:


  • Very easy installation - drill only one hole (120mm diameter) for a special separate air extraction / supply pipe

  • Effectively ventilates - supplies fresh ambient air to the premises (two speeds - 16 or 52.5 / h), removing cold air from them;

  • Features a patented Lossnay plate heat exchanger with temperature (temperature exchange efficiency up to 85%) and humidity exchange

  • 2 filters installed

  • Very low power consumption: only 4.5 W in low mode (-20 W in high mode)

  • Ventilation of the premises with a recuperator prevents ambient noise and pollutants from entering - thus ensuring a comfortable and healthy indoor microclimate

The device can be mounted both horizontally and vertically. This is especially true for interior apartments, where there is not much space in the outer walls.


The recuperation system VL-50S2-E is easily mounted on the outer wall of the building by drilling a single hole into which a special plastic pipe is inserted. It is separated by a partition - in this way the fresh air removed from the premises does not come into full contact with the drawn-in outdoor air (air removal and fresh air supply take place at the same time), and this tube already undergoes temperature exchange, ie for fresh cold ambient air (open in summer).


This mini-recuperation system is designed so that only fresh air enters the patented Lossnay heat exchanger by crossing the hot and cold air streams and a special membrane separating the outlet and inlet air streams. This recuperation system VL-50S2-E is very compact, so it can be used even in indoor apartments, where there is usually not enough space to install similar systems. With this recuperation system, energy is not wasted when ventilating the premises, and fresh air always enters the premises.
