<strong>HOWATHERM</strong> Klimatechnik has been specializing<br />
for nearly 30 years in the development<br />
and production of efficient<br />
systems for air handling applications to<br />
create and maintain comfortable indoor<br />
atmospheres for people.<br />
In the evaluation of contracts, operating<br />
costs have long been a key parameter. An<br />
environmentally responsible and economical<br />
use of resources, in both the manufacture<br />
and the use of AHU equipment, are<br />
important decision-making factors to specifiers<br />
and equipment users. Electrical<br />
power savings are a particularly important<br />
criterion.<br />
This is why <strong>HOWATHERM</strong>'s engineers, in<br />
their ongoing design improvement, have<br />
made the reduction of electrical power<br />
consumption an overriding objective.<br />
Investment and operating cost<br />
estimates<br />
An evaluation of our ETA SYSTEM versus<br />
conventional designs may appear to show<br />
initially higher investment costs.<br />
If the equipment side is included in these<br />
calculations - and about 60% of all systems<br />
require converter control - the frequency<br />
converter cannot generally be taken into<br />
account in the pre-investment analysis.<br />
Without the frequency converter, however,<br />
the investment cost of an ETA SYSTEM<br />
looks even more favorable when compared<br />
against conventional equipment, given<br />
the reduced mechanical complexity. And<br />
even if the frequency converter is included<br />
in the analysis, the ETA SYSTEM offers payback<br />
periods of 1 - 2 years on average.<br />
With the fundamental option of an ondemand<br />
flow control system, this payback<br />
period will be cut by another 50%.<br />
Evidently, the elimination of the belt drive<br />
can often make a second filter stage dispensable.<br />
Let us assume that you intend to replace a<br />
conventional AHU with one from our<br />
energy-optimized ETA SYSTEM range, all<br />
other design characteristics being equal.
