Optional Equipment (continued)
Environmental monitoring unit
A stand-alone unit performs continuous
temperature and humidity sensing through two
available probes (one included) and contact
monitoring. The unit is controlled by available
web, control console, or SNMP interface with
network connection. In the event of an
environmental anomaly, notification is sent to
the customer via e-mail or SNMP. The unit is
18.25" × 9" × 2.75" (464 mm × 229 mm × 70
mm) and sits in or on top of a rack. The probes
extend up to 12' (3.66 m) from the unit.
Hot water or steam reheat
An on/off solenoid valve for steam reheat, or a
modulating valve for hot water reheat maintains
the dry bulb temperature when the system is in
dehumidification and heat mode. Completely
factory pre-piped, the system includes a copper
tube, aluminum-fin reheat coil, solenoid valve,
float, and thermostatic and steam trap for steam
reheat only.
Hot gas reheat
The copper tube, aluminum fin hot gas reheat
coil maintains the leaving dry bulb temperature
when the system is in the dehumidification
mode. The coil is controlled by the
microprocessor through a factory-piped and
wired three-way heat reclaim regulator and
check valve (water/glycol only).
High efficiency filter(s)
Pleated final filters with an efficiency of 40% and
60% (ASHRAE 52.2), 4" (102 mm) deep, allow
the removal of a greater percentage of airborne
particulate contaminates.
Prefilter(s)
Intended to capture large airborne particulate
contaminates, thereby extending the life of the
high-efficiency filter. Prefilters are 1" (25mm)
deep and easily disposable.
Condensate pump
The factory installed and wired condensate
pump will pump 36 gal/h (0.06 L/s) at 15ft. (4.6
m) head.
High pressure water regulating valve(s)
Water and glycol systems may utilize an optional
regulating valve, which operates with a
maximum pressure of 350 psi (2400 kPa), to
automatically control condensing temperature.
Hot gas bypass
An auxiliary side-port hot gas bypass circuit. The
activation of the hot gas bypass circuit will
maintain the evaporator coil temperature during
low load conditions will offer longer compressor
run times and minimize compressor cycling and
temperature fluctuations.
