Cooling Options:

Evaporative Cooling – Adding evaporative cooling may simply be done by adding an evaporative cooling section. The evaporative cooling section includes a galvanized steel housing with a louvered intake, 2-inch aluminum mesh filters and a stainless steel evaporative cooling module. The evaporative cooling media is Munters CELdek or GLASdek and has a depth of 12 inches for 90% cooling effectiveness.

The entire section mounts directly to the front of the unit, eliminating transition or ductwork by others. Drain and overflow are conveniently tapped through the side of the cooling section. The supply line connection is field located where convenient. Freeze protection, automatic drain & fill, and the Water Wizard™ are available.

Cooling Coils – Chilled water or direct expansion (DX) cooling is available with the model XIGX. The cooling section includes the cooling coil, sloped stainless steel drain pan and insulated double wall construction. Drain and coil connections are stubbed through the wall for convenience.

For proper coil sizing, contact your local Accurex representative. Four-row and six-row chilled water or DX coils are available with airflow capacities up to 11,000 cfm (18,689m³/hr). Cooling coil sections are installed upstream of the fan section for a draw through arrangement and provide a streamlined transition to adjacent XIGX sections. DX coils require remote condensing units.

Furnace Control - Choose from staged or modulating furnace control:

Temperature Control:

  • Discharge Temperature Control- Model XIG and XIGX controls heat output based on discharge temperature. A factory mounted discharge temperature sensor feeds information back to the unit control center. The furnace(s) either stage or modulate the heat output to satisfy the discharge temperature set point. The set point is easily field adjustable with a dial located in the furnace control center. For make-up air applications, single-stage furnace control is not recommended.
  • Discharge Temperature Control with Room Override - The room override option enables a make-up air unit to boost its heat output when the space temperature is cooler than desired. When the space temperature is satisfied, the XIG and XIGX will control heat output based on the normal discharge temperature set point. When the space is too cool, the discharge temperature will be elevated, typically by 20°F (-7°C), until the override thermostat is satisfied. Room sensor may be wall/beam mounted or included on a remote control panel.
  • DDC Interface - The discharge temperature can be controlled by a DDC signal. The DDC options provides an factory installed interface, allowing easy integration into your building management system. The discharge temperature can be controlled using a 2-10 VDC or 4-20 mA signal.

Weatherhoods with standard G90 galvanized steel construction are available:

  • Birdscreen Weatherhood - The birdscreen weatherhood includes a mesh screen that prevents large debris from entering the unit. An additional filter section for smaller debris is required.
  • Filtered Weatherhood - The filter weatherhood includes aluminum mesh filters installed in the weatherhood, eliminating the need for an additional filter section. Redundant filtering is possible with the addition of a filter section to the filtered weatherhood. A filtered weatherhood should be your first choice when a cost competitive solution is needed for your make-up air application.
  • Louvered Weatherhood - The louvered weatherhood is designed to keep debris and moisture out of the unit and your building in the most compact design possible. This combo weatherhood includes aluminum mesh filters and a moisture reducing louver to reduce water entering the unit.

Remote Control Panels :

  • Accurex's fan control center, model XFCC, is designed to control the exhaust fans, supply fans and lights for the kitchen ventilation system. Model XFCC has numerous options and can be interlocked with the fire suppression system.
  • Kitchen style remote panels feature lighted toggle switches and a stainless steel face plate for flush mounting to a wall. The junction box is also included.

Air Filter Gauge – Indicates when filters become dirty. An indicator light may be wall/beam mounted or provided with a remote control panel.

Motorized Dampers – Intake or discharge dampers are available to prevent backdrafts when the fan is not in operation. Intake dampers are factory mounted and wired.

Exhaust Fan Starter(s) – Up to 2 exhaust fan starters may be added to the control center.

Inlet Air Sensor – An on/off type duct stat automatically de-energizes the gas system and interrupts the flow of gas to the burners when the inlet air temperature is above the desired setting.

115 Volt Service Receptacle – A 115 volt GFCI outlet is mounted externally in a NEMA-3R box for the convenience of field service personnel. A separate 115 volt power source is required.

Roof Curbs – Factory provided roof curbs are available to ensure compatibility between the make-up air unit and roof curb. Standard construction is G90 galvanized steel. See the roof curbs section in this catalog for more information.

Equipment Supports – Factory provided equipment supports may be required in addition to a roof curb, depending on the specified unit configuration. Standard construction is G90 galvanized steel.

Freezestat – An on/off type discharge duct stat (with a timer) prevents the discharge of cold air into the building when the furnace(s) is not providing adequate tempering.

Special Coatings – Permatector™ powder coating is available if a painted look is desired. Decorative baked enamel coatings are also available in a variety of colors to match existing building fixtures. Consult your Accurex representative for coating selections.

Fiberglass Insulation – Fiberglass insulation is used to line the housing to prevent the formation of condensation and to form an acoustical barrier.

2-Speed Motor – A 1⁄3 reduction 2-speed motor is available, provided that the temperature rise at maximum output is within acceptable limits for both speeds.

Variable Frequency Drive – A variable frequency drive is available to automatically vary the fan speed.

Propane Gas – A propane heater may be provided in lieu of natural gas.

Duct Adapter – Duct adapter is available with factory supplied curbs and allows an easy method for connecting ductwork to curb.

Double Wall Construction – An interior metal liner is available to isolate insulation from the airstream. One inch thick insulation is included with this option.

Gas Pressure Regulator – Required if building gas line pressure exceeds the maximum inlet gas pressure of 14 in. wg.

Weatherhood – A galvanized steel weatherhood with birdscreen is standard on 100% outdoor air units. A louvered intake is optional.
