Product Overview

Ventilation for schools, restaurants and offices

The VRL-C D Premium centralised heat recovery ventilation system recovers up to 92% of the heat that would otherwise be lost through an open window. Installation is simple and can be implemented quickly. In this way, individual devices ensure optimal ventilation of the entire classroom independently of one another — the old air out, fresh and the healthy air in.

Product Details

Application

Typical applications are the controlled ventilation of larger rooms such as classrooms, meeting rooms, child-care centres, restaurants and event rooms. Thanks to the integrated filter and heat recovery, the automatic room ventilation improves the air quality in the room and lowers the proportion of CO2, aerosols, spores and dirt. At the same time, the permanent air exchange reduces the pollution of the room air with odours, bacteria and viruses.

Comfort features

Operating modes, programs and parameters can be set easily and intuitively with the control unit. The devices are easy to maintain and designed for quick and easy service. An additional sensor (accessory) measures the CO2 concentration of the room air and regulates the air output of the device fully automatically until the CO2 value falls below the set value again.

The device can be switched to basic ventilation or a higher air level via a motion sensor (accessory). The temperature-controlled bypass enables the heat recovery to be bypassed automatically. The devices are all equipped with an electrical preheater and can also be used at low outside temperatures with balanced supply, and exhaust air volume flows. The systems are equipped with motorized outside and exhaust air flaps to prevent uncontrolled airflow during standstill. In the event of a fire or loss of voltage, the spring-loaded outside and exhaust air flaps close the airways and thus help to minimise the spread of fire and smoke gas in the building. In larger buildings, up to 20 devices can be connected to one another and controlled using just one control unit. The devices are connected to a higher-level building control system using BacNet, Modbus and LON interfaces (accessories).

Installation

This device is designed for ceiling mounting and can be integrated into a suspended ceiling. It can be installed at different points on the ceiling. The nozzle for the supply airline is located on the front of the device. The exhaust air is routed via the exhaust air nozzle on the narrow right-hand side.

Efficiency

Energy-saving EC fans, in conjunction with the control and other sensors, enable efficient operation.
