puravent Thermozone AR 300 E/W Water Heat Air Curtain

Thermozone AR 300 E/W

Recessed air curtains for installation heights up to 3.5 metres.

Application
AR300 is especially suited for environments with high demands in respect of design. The recessed installation is very discreet and the built-in control contributes further to the concealed appearance.

Comfort
Several factors need to cooperate to create a comfort-able indoor climate. With Thermozone Technology an efficient air separation is created in combination with a low sound level. The dual functionality as air curtain when the door is open and part of the heating system when the door is closed also contributes to good comfort.

Operation and economy
The air curtain has a low energy consumption thanks to Thermozone Technology and the extra function as heat source means further savings. Built-in controls, easy installation and maintenance minimizes the cost and the risk for errors.

Design
AR300 is designed for recessed installation and colouring is possible to make it blend even better with the premises.

Product specifications

• Optimized airflow with Thermozone Technology.
• Intelligent, built-in control, operating both when the door is open and when it is closed gives the air curtain dual functionality.

• 1. ∆t = temperature rise of passing air at maximum heat output and lowest/highest airflow.
• 2. Conditions: Distance to the unit 5 metres. Directional factor: 2. Equivalent absorption area: 200 m2.
• 3. Applicable at water temperature 80/60 oC, air temperature, in +15 oC.

Protection class AR300E/W recessed mounting: above false ceiling – splash- proof design (IP44), below false ceiling: normal design (IP20). Approved by SEMKO and CE compliant.

Control
The built-in control of AR300 is designed to give the highest level of functionality while minimizing installation and daily operation. No additional wiring or external controls are needed. If the distance between the eye and the reflector is too long, it is possible to use an external door contact instead (accessory). The air curtain operates at its maximum performance in all situations and is not dependent on day-to-day adjustments.When the door is open the air curtain separates outdoor and indoor air and provides heat if it is needed. When the door is closed the air curtain operates as part of the heating system supplying additional heat if indoor temperature falls below desired temperature. There are also possibilities to connect the air curtain to a BMS system for on/off control and alarm indication.

Dimensions

Mounting and connection

Mounting
AR300 unit is installed horizontally with the supply air grille facing downwards as close to the door as possible, concealed in the false ceiling. The only visible part of the unit is the underside that is level with the ceiling. For the protection of wider doorways, several units can be mounted next to each other. Ensure that the service hatch is accessible and can be fully opened. Minimum distance from outlet to floor is 1800 mm, see Fig. 1.

Adjusting
An IR-eye is mounted on AR300. A piece of reflector tape is also supplied. The door sensor can be directed up/down to ”see” the tape, see Fig. 1. The maximum distance between the IR-eye and the reflecting tape is 1,8 m. If higher degrees are needed should the reflecting tape be angled towards the IR-eye. This is easily done with the enclosed cylinder cut to the right angle.
When the distance between the eye and the reflector is too far, an external door contact (AR300DS) can be used.

Connection AR 300 E
Connection is made on the top or on the side of the unit with a five-wired cable with earth. The supply terminal block is intended for a cable of maximum 16 mm². See wiring diagrams.

Connection AR 300 W
Connection is made with cable and plug. Connection of water pipes to the water heating coil is of type DN20 (3/4”), inside thread. Cable glands can be made from the back, top or the sides of the unit. There are premarked holes for drilling at these locations. See Fig. 2 and wiring diagrams.

Control kits

Electrical
The IR-eye detects when the door is open and closed. Airflow and heat output are controlled automatically based upon room temperature and whether the door is open or closed. High speed can be set on 4 different speeds. When the door is open the fan runs on high speed, when the door closes the fan will continue to run on high speed for 60 seconds and then on low speed for 60 seconds. When the door is closed the fan runs on low speed if there is a need for heating, if not the fan will be switched off. If the temperature decreases further, the fan will run on high speed. The built-in room thermostat controls the heat output. E.g. the thermostat is set on 20 °C and the difference between the stages 2 °C. The thermostat will activate below 20 °C when the door is closed. When the door opens, the thermostat will activate below 22 °C and normally the heat is switched on. Possibility to choose between heat/ambient mode (summer case). Alarm, door status and heat/ambient mode is indicated with diodes on the IR-unit.

Accessories

AR300ERS, external room sensor
If an external room sensor is needed, use the AR300ERS. The external room sensor is supplied with 7 m cable and a modular contact for easy and quick installation (no other adjustments are needed to get the accessories working). The connection of the room sensor is done on the control box accessible by opening the service hatch of the AR300.

AR300DS, external door contact
When the distance between the eye and the reflector is too long an external door contact AR300DS is needed. The external door contact is supplied with 7 m cable and a modular contact for easy and quick installation (no other adjustments are needed to get the accessories working). The connection of the door contact is done on the control box accessible by opening the service hatch of the AR300.
