The Ecosaire subsidiary of Dectron
Internationale has added a space-saving direct drive fan, environmentally
friendly R-410a refrigerant, and energy-saving free cooling to its Spacemaker
(SM) Series of precision air conditioning equipment for data equipment centers,
telecommunications rooms, digital switchgear sites, medical equipment rooms,
electrical rack rooms, internet server vaults and other critical cooling
environments.
 The SM Series is
available in sizes of two to seven tons. Besides cooling, unit customization
can include gas phase and/or ultraviolet filtration to eliminate airborne
contaminants, dehumidification to reduce corrosion-causing condensation,
humidification to eliminate static electricity, energy-saving hot gas reheat,
and many other options factory-interfaced and packaged for single source
responsibility. Larger units up to 40 tons are available from Ecosaire’s EC
Series. The replacement of previous belt drives or blower configurations by the
direct drive fan reduces the SM Series’ already compact footprint by an
additional 35 percent, making it one of the HVAC industry’s smallest precision
a/c unit footprints and perfect for space-challenged environments. The direct
drive also enables the energy-saving options of a variable frequency drive
(VFD) or electrically commuted (EC) motors.
The addition of free
cooling reduces energy costs by up to 50 percent in northern climates by
utilizing wintertime ambient outdoor air and a glycol loop to cool instead of
the unit’s direct expansion (dx) refrigeration circuit. For sites with
available chilled water loops, the SM Series also offers an optional dual
cooling feature where the glycol loop provides primary cooling and the dx
circuit serves as a redundancy back-up, thus eliminating the expense of a
second unit or two dx circuits for redundancy. According to the company’s press
release, the SM Series also includes double-wall case construction that
separates R-value insulation from the air stream to enhance IAQ; supervisaire
on-board microprocessor capable of either self-sufficient
controlling/monitoring or interfacing with all protocols of building automation
systems. |
