TOP MARKS FOR HVAC DRIVES
Ireland’s leading manufacturer of air handling units for
heating, ventilating and air conditioning has standardised on AC
variable speed drives from Control Techniques.
Mark Eire BV, part of the Mark Holding Group of Holland,
manufactures a wide range of stand alone and integrated air
handling units and heaters in Macroom, County Cork, for the
environmental control of commercial and industrial premises.
With a high throughput of units from 7,000 to 40,000 cu metres per
hour, the company uses the Commander SK AC drive (2.2 kW – 22 kW)
from Control Techniques as its drive of choice.
“We switched over some four years ago from a system of geared
pulleys to alter the air volume to variable speed drives,” explains
Paraic Ó Conaola, Purchasing Manager at the plant. “From the
outset, we used Control Techniques Commander SE drives, then
switched to the new Commander SK when the range was
introduced. Whilst price is important in this very
competitive market, the physical size of the drives is a crucial
factor. The Commander SK drives are so compact that they can
be integrated into the air handling unit itself, eliminating the
need for a separate cubicle. In commercial and industrial
premises, space costs money!”
The switch to variable speed drives improved the energy
efficiency of the air handling units, precisely matching motor
speed to the actual air demand.
The Commander SK units are very quick and easy to set up, according
to Electrical Technician, Brenda Curran. “It’s just a matter
of a couple of minutes,” she says. “We use the autotune
feature, where the drive sets up the basic parameters itself and
smooths out any motor noise. We simply set the minimum speed,
usually 38 Hz and the maximum 50 Hz. The display shows
diagnostics too. Final set-up is carried out on site since
air volumes are rarely exactly as quoted and this is very easy to
do.” >>>>>>
