Ventilair Calma Centralized Heat Recovery Ventilator
Price range: 1.016,40 € through 2.601,50 €
The Ventilair Calma is a heat recovery ventilation system designed for applications that require reliable, ducted airflow with flexible capacity options. Available in seven airflow variants, it uses a crossflow heat exchanger to recover heat from extracted air while supporting balanced ventilation throughout the building. With integrated bypass, smart control capability, and adaptable installation layouts, Calma is suited to residential and light commercial projects where performance, flexibility, and control are key requirements.

The Ventilair Calma range is designed to provide dependable heat recovery ventilation across a wide range of building sizes and usage requirements. By offering multiple airflow variants — from 150 m³/h up to 1000 m³/h — the range allows specifiers and installers to select the appropriate capacity without over- or under-ventilating the space.
At the heart of the system is a crossflow heat exchanger, designed to recover thermal energy from extracted air before it leaves the building. With a heat recovery efficiency exceeding 77%, Calma supports indoor comfort while helping reduce unnecessary heat loss during ventilation.
The unit includes a 100% bypass facility, allowing fresh air to be supplied without passing through the heat exchanger when conditions require it. This provides operational flexibility during milder weather or when heat recovery is not desired, supporting more responsive ventilation strategies throughout the year.
Construction is based on an integrated EPS structure combined with galvanised steel plate, providing a balance between insulation, durability, and structural stability. This design supports consistent operation while contributing to thermal separation within the unit.
Installation flexibility is a key consideration in the Calma range. The unit supports optional air inlet and outlet configurations in different directions, making it easier to adapt to site constraints and duct routing requirements. This flexibility is particularly useful in retrofit projects or plant rooms with limited space.
Ventilair Calma is designed to integrate into modern building control strategies. It features a smart control system with RS485 connectivity, allowing communication with external control systems where required. Additional control features include filter alarm notifications, sleep mode, and optional WiFi control, giving users and facility managers multiple ways to monitor and adjust operation.
The Calma range is intended for projects where a centralized heat recovery solution is required. It works as a central ventilation unit serving multiple spaces via ductwork, complementing other building systems such as local bathroom extractor fans or kitchen extraction where moisture is generated at source.
Ventilair Calma is aimed at residential developments, apartments, offices, and light commercial environments that require scalable ventilation capacity, consistent performance, and adaptable control without unnecessary complexity.
