The CRS by Sicflux is a compact and efficient air exhaust/intake unit designed for spaces such as apartments, homes, and offices. This device performs two functions simultaneously: it brings in fresh, clean air from the outside and expels indoor air. During exhaust, the thermal energy from the indoor air is transferred to the heat recovery unit plates, either heating or cooling the incoming air depending on the season. This feature helps reduce energy costs by minimizing thermal losses.
Model Variety: Available in various sizes including CRS 100, CRS 125, CRS 150, and CRS 200, to meet different ventilation needs.
About the Product

Technical Specifications
Operating Logic
1 – Air extracted from the room (cold or warm):
Indoor air is moved by the motor, passes through a filter to remove impurities, and reaches the thermal recovery cell. In this cell, the air transfers its thermal energy to the internal elements and is then expelled to the outside.
2 – Air brought in from outside:
Outdoor air is drawn in by the motor, filtered for purification, and then passes through the recovery cell. The cell absorbs part of the thermal energy from the extracted indoor air, and the air is then delivered back into the room.
3 – Thermal energy recovery:
Indoor and outdoor airflows cross through the heat recovery cell. This process reduces thermal energy loss, helping to optimize the system and lower operating costs for air heating or cooling, making the environment more energy-efficient.
