Cooling options

Evaporative Cooling

An evaporative cooling section includes a galvanized steel housing with a louvered intake, two inch aluminum mesh filters and a stainless steel evaporative cooling media housing. The evaporative cooling media is Munters CELdek or GLASdek and has a depth of

12 inches for 90% cooling effectiveness.

Drain and overflow lines are conveniently stubbed through the side of the cooling section. The supply line connection is field located where convenient.

IGX-HV airflow capacity for evaporative cooling is up to 14,000 cfm. Below 9,000 cfm, evaporative cooling modules ship attached and factory wired. Field attachment is required for airflow above 9,000 cfm.

Mixing Box Controls:

Mixing box control option EC1 is recommended for use

with evaporative cooling. On a call for cooling when the outdoor air temperature is below the economizer setpoint, the dampers modulate to provide cool mixed temperatures down to 55° F. When the outdoor air is

above the economizer setpoint, the evaporative cooling section is energized and the dampers travel to the 100% outdoor air position.

The MB mixing box options are NOT recommended in conjunction with evaporative cooling.

Cooling Coils

Model IGX-HV boasts the flexibility of Chilled Water or Direct Expansion (DX) cooling with capacity to 11,000 CFM. The cooling section includes the cooling coil, stainless steel drain pan and insulated double wall construction. Drain and coil connections are stubbed through the wall for convenience.

For proper coil sizing, use Greenheck’s Computer Aided Product Selection (CAPS) program or contact your local representative. Four and six row coils are available.

Cooling coil sections are installed downstream of the mixing box section for a draw through arrangement. This provides a streamlined transition to adjacent IGX-HV sections. DX coils require remote condensing units.

Mixing Box Controls:

All MB and EC mixing box control options are available with chilled water or DX cooling coils.

For economizer climates, the EC1 option is recommended. Mixing box options operate as described on page 4.

Thermostats:

The cooling coil and MB mixing box control options may use a 1-stage (chilled

water or single stage DX) or 2-stage (dual stage DX) cooling thermostat.

The cooling coil and EC mixing box control options require a 2-stage cooling thermostat. Economizer represents the first stage of cooling and a single DX stage or chilled water coil represents the second stage of cooling.
