3.2 Optional features
Air cooled models
SUPPLY AIR BAFFLE
A field adjustable, modular supply air baffle is located in the discharge air
stream. It can be quickly and easily reconfigured to redirect airflow. The angles of the vanes have been
optimized to effectively distribute air to heat generating equipment in a wide variety of applications.
CONDENSATE PUMP
It has a capacity of 50 l/h at 3.7 m head. A float signal is available for a remote
alarm. Please notice that at 4 m head the flowrate is 0.
HUMIDIFIER
A steam generating canister humidifier is factory-installed in the cooling unit and is oper
-
ated by the iCOM control system. It is complete with disposable cylinder, all supply and drain valves,
steam distributor and electronic controls. The need to change the canister is inticated on the iCOM
display, if available. The humidifier is designed to operate with water conductivity from 125-500 (50Hz)
microS/cm. System automatically fills and drains as well as maintains the required water level based on
conductivity. An air-gap within the humidifier assembly shall prevent backflow of the humidifier supply
water. The humidifier is removable from the rear of the cabinet.
ELECTRIC REHEAT
The electric reheat coils are low watt density, 304 stainless steel fin-tubular con
-
struction, protected by thermal safety switches and controlled in one stage.
INTELLISLOT UNITY CARD (IS-UNITY-DP)
Provides monitoring via SNMP, Modbus (RS485/IP),
BACnet (RS485/IP) and HTTP (Web) protocols
INTELLISLOT SITESCAN CARD (IS-485EXI)
Provides monitoring via Liebert SiteScan Web 4.0 Pro-
tocol
FILTER
The optional F5 class (following EN779) filters are two deep pleated 60 mm, located within the
cabinet and accessible from the rear of the unit. A filter clog alarm is included as an option.
ONE (1) EXTRA COMMON ALARM CONTACT
Provides the customer with a total of two sets of nor-
mally open (n/o) contacts for remote indication of unit alarms.
LIQUISTAT
SENSOR Is a solid state water sensor that has no moving parts and is hermetically sealed
to keep out dust and dirt. When the sensor detects the presence of moisture the alarm system is acti-
vated.
DUAL POWER SUPPLY
with an internal automatic transfer switch is available as an option. With this
option the unit can be connected to 2 separate power supplies where each power supply is able to com-
pletely feed the unit. In case of failure of the main supply the unit automatically switches to the second
power supply. This allows to have a complete power supply redundancy.
Chilled water models
CONDENSATE PUMP

ELECTRIC REHEAT
The electric reheat coils are low watt density, 304 stainless steel fin---tubular
construction, protected by thermal safety switches and controlled in one stage.
2-WAY MODULATING VALVE
A 2-way modulating valve controls the chilled water flow passing through
the cooling coil. The iCOM control manages the valve actuator movement in order to provide the de-
sired amount of cooling for various entering water flow rates and temperatures. Cooling capacity is
regulated by closing-off the chilled water flow. The maximum differential pressure across the closed
valve is 175 kPa. Maximum system pressure is 1586 kPa.

stream. It can be quickly and easily reconfigured to redirect airflow. The angles of the vanes have been
