OPTIMA-S Single skinned rectangular or square Variable air flow controller

Description

Single or double skin circular VAV (Variable Air flow Volume) controllers are commonly used for return air applications or for supply air applications. OPTIMA-S controllers are ideal for single zone control with supply and return in Master and Slave setup such as offices, hotel rooms or meeting rooms or larger public or industrial halls where the required cooling and heating load will vary on demand.

Design

OPTIMA-S controllers are constructed from galvanized sheet steel casing and aluminium profile blades. The casing contains a robust flanged mounting frame to assure the sturdiness of the controller and to facilitate the mounting to ducts.

The aerofoil blades are opposed action and are made from extruded aluminium. The blades are equipped by rubber gaskets eliminating leakage in closed position. The blade axes are sitting in self lubricating polymer bearings.

The blades are linked by a cog/rod positioning mechanism. The measurement probe from alunimium is connected to the VAV controller by flexible polyurethane impulse tubing.

Available sizes (mm): 200 × 100 to 1200 × 1000 with steps of 50 mm in height and width.

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 default 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.
