Order Supply unit Vents PA 04 V in Valencia at a great price

Vents PA 04 V is an air handling unit with a water heater. Designed for use as part of a supply ventilation system to provide constant or periodic fresh air supply. The nominal capacity of this model is 4100 m3/h, it is connected to air ducts or other elements of the ventilation system with a cross-section of 700x400 mm.

The supply unit uses a water heater, which involves the use of an external source of hot water from a boiler or other sources. To regulate water flow, it is necessary to additionally use a mixing unit. The unit is supplied with a built-in automation system.

House

The unit body is made of aluminum-zinc. Sound insulation and thermal insulation are achieved through the use of a 50 mm thick layer of mineral wool.

Filter

A filter with replaceable inserts is used to filter the outside air in the unit. Filtration class - G4.

Heater

PA units are equipped with water heaters. There are two-row, three-row or four-row versions.

Fan

The units are equipped with a high-pressure frameless radial fan directly driven by an electric motor with an external rotor. The impeller blades are curved backwards. The fan provides optimal performance characteristics: air flow, noise level and efficiency. The fan can be easily removed from the housing for inspection and cleaning.

Installation

The Vents PA 04 V air supply unit is mounted on the floor, suspended from the ceiling using a mounting bracket with a vibration insert, or mounted on the wall using brackets. The installation can be placed both in auxiliary rooms and in the main ones (above a suspended ceiling, in a niche or in an open way). All electrical connections are made through the terminal block located in the junction box.

PA air handling units are equipped with brackets to facilitate installation of the unit. The unit can be mounted in any position, except vertical, when the air flow is directed downwards (heating elements should not be under the fan). It is necessary to provide for the possibility of access to the unit in cases of servicing and cleaning the filter.

Control and automation

The unit comes with a built-in control and automation system that allows you to adjust the fan performance (3 speeds), set the supply air temperature, monitor the condition (degree of contamination) of the filter. In addition, the automation system provides active protection against overheating of the heater heating elements (for PA...E). The unit can be controlled from a distance using a remote control.

The remote control provides

• turning on/off the ventilation unit
• the ability to set the required air flow ,
• opportunity to set the desired supply air temperature,
• display of room temperature,
• display of a fault (emergency situation).

PA...V control and protection functions

For systems with a cooler, automation panels are additionally equipped with a room temperature sensor-setter. The switchboard includes an electric drive for the air valve LF230. Heater piping components (pump, valve, three-way drive, etc.) are not included in the package.

Functionality

1. Automatic control of the supply air valve PPVA.

2. Monitoring and indication of filter contamination.

3. Smooth control of fan speed 3~380V (50Hz).

4 Maintaining a given supply air temperature or room temperature.

5. Control of a liquid air heater and monitoring its operation.

6. Control of a compressor-condensing unit (CCU) for systems with a cooler .

7. Exhaust fan start signal.

8. Possibility of individual configuration of all parameters of the ventilation system.

9. Stopping the system upon a signal from the fire alarm panel.
