Rectangular Variable Air Volume units
Item Number: 63250
Single or double skin rectangular VAV terminal units are commonly used for return air applications or for supply applications at low system pressures. OPTIMA terminal units are ideal for single zone control with supply and return in Master and Slave setup such as offices, hotel rooms or meeting rooms as well as larger halls where the required ventilation, cooling and heating load will vary on demand.Highlights:
• Damper tightness class 4 according to EN 1751
• Casing tightness class C according to EN 1751
• High measurement / control accuracy of 5 %
• Operating range of up to 1000 Pa
• Double skin version OPTIMA-SI with external isolation under steel sheet cover for noise reductionDesign
VAV unit housing is made from galvanized sheet steel. The multiple opposed - action damper blades with gaskets for air tight shut - off are made from anodized extruded aluminium profile. The blades are moving by cog/rod linkage mechanism in polymeric bearings. The duct connections are equipped by 20mm flanges. The dynamic pressure measurement probe consists from aluminum pipes connected to the pressure sensor by polyurethane impulse tubing.Controls
The VAV controllers are as standard equipped by compact controllers/actuators with analog setpoint and feedback signals in mode DC 2 V … 10 V or DC 0 V … 10 V. The compact controllers are equally available with MP-BUS, MODBUS, BACnet, KNX and LON communication capability. On demand as alternative, Gateway communication units can be provided and can be connected later in time to building management systems (only possible with MP-BUS communication on board). VAV compact controllers are factory calibrated as standard to the air volume or upon request can be adjusted to site required settings prior to dispatch on Vmin and Vmax range. The air volumes can also be readjusted on site with ZTH-EU hand held service tool or, for the type OPTIMA-…GO… by dials on the controller. If specific air volumes for Vmin and Vmax would be required, this must be indicated prior to order of the units for adequate calibration in the factory.
