ADVANTAGES OF THE ECO
ENERGY SAVINGS
The Eco range provides considerable potential for
energy saving in the following areas:
•
Air flow requirements are matched precisely to
demand.
•
Optimum system regulation means less
energy/power is required.
•
The requirement for changing clean air filters
is reduced.

CONTROL & REGULATION
The Eco range enables the following
improvements to system control and regulation.
•
Finer control of system functions as the Eco
accurately follows set points.
•
Closed loop process control using a standard
Proportional, Integral, Derivative (PID) control
loop function.
•
Reduced overshoot of pre-set parameters,
provides optimised levels of comfort.
•
Automatic compensation for system
fluctuations - partially blocked filters.

NOISE
Noise reductions can be achieved by reduction in:
•
Motor and fan rpm.
•
Air flow velocity
•
Balance dampers are set in a more open
position.
•
Periodic on/off actions create a higher and
more irritating noise level than continuous
running
