Vents VUT 530 EG

Vents VUT 530 EG is an air handling unit using heat recovery. This model is equipped with an electric heater with a power of4 kW,the nominal capacity of the installation is530 m3/h. The unit is intended for use as part of a supply and exhaust ventilation system for residential or commercial premises.

Installation of the unit must be carried out in a closed room with a positive temperature. The ventilation unit must be used with an air duct system with a root section of 160 mm.

All units in this series are supplied with an automation kit; the unit is completely ready for operation and does not require additional adjustment.

House

The body is made of aluminum-zinc steel with internal heat and sound insulation made of mineral wool 25-50 mm thick.

Filter

To filter supply and exhaust air, the unit has two built-in filters with a cleaning degree of G4 (exhaust) and F7 (supply).

Fans

Vents VUT 530 EG units are equipped with supply and exhaust double-suction centrifugal fans with forward-curved blades and a built-in protection thermostat with automatic restart. Electric motors and impellers are dynamically balanced in two planes. Rolling ball bearings of electric motors do not require maintenance, the service life is at least 40,000 hours.

Recuperator

The installations use highly efficient cross-current recuperators made of aluminum plates. Under the recuperator block there is a tray for collecting and discharging condensate.

Heater

To operate the air handling unit at low outside temperatures, an electric heater is installed. If using heat recovery it is not possible to achieve the set value of the supply air temperature, the heater automatically turns on and heats the air entering the room.

Control and automation

The installation is equipped with a built-in automation system and a multifunctional control panel with a graphic indicator. The standard installation kit includes a 10 m long wire for connecting to the remote control. To prevent the recuperator from freezing, electronic anti-freeze protection is used using a bypass and a heater. Its essence is that, based on the temperature sensor, the bypass damper opens and all the supply air passes past the recuperator through the bypass channel.

During the defrosting period of the recuperator, the supply air is heated to the required temperature in the heater. During defrosting, warm exhaust air warms up the recuperator. Then the damper closes the bypass, the heater turns off, the supply air again passes and is heated through the recuperator, and the entire installation operates as usual.

Control and protection functions of VUT EG

• turning the unit on and off,
• the ability to use the control panel to set the desired supply air temperature and maintain specified,
• the ability to use the control panel to regulate the fan rotation speed and, accordingly, change the performance of the installation,
• the ability to connect electric air damper drives and control them,
• when turning the unit on and off, the necessary algorithms are worked out,
• the unit can operate on a weekly timer,
• active protection against overheating of the heater heating elements,
• excluding the operation of the electric heater without turning on the fan,
• two thermostats are installed to protect the electric heater from overheating,
• the automation system is protected from short circuits by a circuit breaker,
• the degree of filter clogging is controlled.

The supply and exhaust unit is equipped with a remote control panel, which provides:

• turning on/off the ventilation unit,
• setting the required air flow,
• setting the required supply air temperature
• displaying the room temperature.

Installation

The supply and exhaust unit is mounted on the floor, suspended from the ceiling using mounting bracket with vibration insert or mounted on the wall using brackets. The installation can be placed both in auxiliary rooms and in the main ones (behind a suspended ceiling, in a niche or in an open way). It can only be installed in such a position as to ensure collection and drainage of condensate. Access for service and filter cleaning is from the side panels.
