1.1 General
The Liebert InteleCool ® 2 Environmental Control System was designed for convenience and dependabil-
ity in unmanned and remote locations typical of the telecommunications industry. Ease of installation,
operation and service coupled with the use of high quality, high reliability components make InteleCool2
ideally suited for maintaining an environment for sensitive electronic equipment. Standard units are
NRTL-C listed/certified to meet U.S. and Canadian safety standards, and MEA listed for New York City
applications. These agency listings insure fast, hassle-free inspection and building code approvals.
Self-Contained
The InteleCool2 product is completely self-contained. All components are enclosed in the weather-
proof cabinet.
Space Savings
The InteleCool2 does not use any of the valuable floor space inside the secure space. Instead, it is
mounted on the outside wall. No additional space is required outside or on a roof.
Easy to Install
The InteleCool2 is assembled, wired, piped, charged with refrigerant, and fully factory tested as a sys-
tem to ensure trouble free installation and start-up.
1.2 Standard Features
Reciprocating Hermetic Compressor—1.5, 2 and 3 Ton Units
The heart of the refrigeration system is a reciprocating hermetic compressor. The compressor features
a suction gas cooled motor, internal centrifugal oil pump, vibration isolating mountings, internal
thermal overloads, and crankcase heater.
Scroll Compressor—4 and 5 Ton Units
The quiet and efficient scroll compressor features a suction gas cooled motor, internal centrifugal oil
pump, vibration isolating mountings and internal thermal overloads.
Refrigeration System
The refrigeration circuit includes a liquid line filter drier, an externally equalized expansion valve,
and a high-pressure switch.
Evaporator Coil
The evaporator coil is constructed of mechanically expanded copper tubes in enhanced surface alumi-
num fins. A coated, galvanized steel condensate drain pan is provided.
Condenser Coil
The air-cooled condenser coil is constructed of mechanically expanded copper tubes in enhanced sur-
face aluminum fins. Components rated for up to 115°F (46°C) ambient.
Evaporator Blower
Evaporator air is supplied by a direct drive blower package. Fans are centrifugal, double width, dou-
ble inlet.
Filter
The filter is 2 inches deep, pleated, with a minimum efficiency rating of 20% (based on ASHRAE stan-
dard 52.1). Located within the cabinet, the filter is serviceable from the front of the unit.
Cabinet
The exterior cabinet is constructed of painted steel. Internal structural parts (including base) are hot
dipped galvanized steel. The evaporator compartment is insulated with 1/2" thick, 2 lb. density, neo-
prene-faced, fiberglass insulation.
Control Interface
The unit is supplied with customary HVAC wiring designations (R, G, W, Y) inside the low voltage
partition of the unit electric box. The control interface can be provided by sources ranging from a wall
mounted thermostat, a Liebert control and monitoring system or a third party building management
control.
