VTS American VENTUS AVS 130 [33/45] Controls

CONTROLS

» automatic modulation of the amount

of outside air (keeping the CO

concentration below the set value)

» optimization of consumption of heat

and electricity

HUMIDITY CONTROL

» control over air humidifying

- both evaporative and steam

» supports control of the drying process

ELECTRIC HEATER CONTROL

» smooth control system that adjusts

power to the current demand

MIXING BOX CONTROL

» smooth control of the mixing box,

external signal or as in the CO

control function,

etc.

» optimization of the ventilation air

to save energy

NEW FEATURES

MEASUREMENT AND CONTROL

OF THE CONSTANT AIR VOLUME

» adjustment of the preset constant air volume

under changing flow resistance - compensation

of changing internal resistance of the AHU (e.g.

with varying degrees of air lter dirt, different

setpoint of the mixing

box, etc.)

» adjustment of the fan power to the current needs

of the installation

» readiness of the AHU to work

with the required performance immediately after

installation

CONSTANT PRESSURE CONTROL

WITH VARIABLE AIR VOLUME

» control of constant, preset air pressure

at variable volume (efciency change

is carried out through the air distribution system

– e.g. VAV controllers)

VTS uses control algorithms that have been developed with an emphasis on energy savings,

while at the same time maintaining the required parameters of the air supplied and ensuring

reliability of our units.

For management of our American VENTUS air handling units we recommend our control

application based on PLC controller, supporting all advanced control functions and variable

ways of external communication including integration with Building Management Systems.

Function and Application

» setting and reading of advanced

operating parameters of ventilation

or supply units

» management and cancellation of

units operational errors is done by
