Optional Features

Humidifier

The humidifier utilizes a pure steam generator specifically designed for precision environmental close control. The pure steam eliminates contaminating mineral deposits, potentially harmful bacteria, white dust, and excessive humidity. The humidifier requires little scheduled maintenance. The humidifier is proportionally controlled to meet the humidification demands of the conditioned space. Humidifier canisters are replaceable.

Electric Reheat

Electric reheat elements are low watt density, wired for 3-phase and loaded equally on all three phases, SCR controlled, and electrically and thermally protected by both automatic and manual reset thermal cut outs. Reheat coils are stainless steel, tubular fin construction.

Spot Water Detector

The solid-state spot water detector is available for both 50 and 60 Hz cooling units. The spot water detector activates an audible alarm on the controller when moisture is detected.

Smoke Detector

The factory-installed smoke detector is designed to sense smoke in the return air stream. Upon detection of smoke, an audible and visual alarm on the microprocessor controller will be activated and the unit will be shut down immediately.

Hot Gas Bypass Valve

The hot gas bypass valve (HGBV) adjusts the flow of compressor discharge gas to the evaporator coil at low load conditions to protect the coil from freezing and the compressor from excessive cycling. 60 Hz cooling units use a mechanical HGBV.

50 Hz cooling units use an electronically controlled HGBV. On 50 Hz cooling units, the HGBV option requires the analog extension board EAIO.

Cable Leak Detector (60 Hz only)

The optional 6 m (20 ft) leak detection sensing cable (APC part number ACAC75105) is available for 60 Hz cooling units only. The cable leak detector is placed on the floor or subfloor around all possible leak sources. If water or other conductive liquids contact the cable anywhere along its length, the master controller visually and audibly announces the leak.

Floorstand

The floorstand raises the unit above the subfloor to match the height of the raised floor. Heights are available from 254 mm (10 in) to 610 mm (24 in) in 76.2 mm (3 in) increments and are adjustable +/– 38.1 mm (1.5 in). Adjustment is provided by threaded pedestals. Vibration- absorbing pads are included. The floorstand, pedestal, and pads ship loose. In areas where earthquakes are a concern, seismic floorstands are available in 305 mm (12 in), 457 mm (18 in), and 610 mm (24 in) heights.

Plenums

Discharge plenums are available on upflow configurations. This application is recommended in rooms where raised floors are not available for air distribution. Discharge air should be ducted down cold aisles.

Base Plenum

Insulated base plenums are available for downflow cooling units where raised floors are not available for air distribution. Four front-discharge configurations are available equipped with dampers, grilles, flexible ductwork or open. All configurations are 450 mm (17.7 in) high and sit beneath the InRoom cooling unit.

Water Regulating Valves

Water and fluid cooled systems utilize two- or three-way valves to regulate the amount of water or glycol supplied to the condenser in response to refrigerant discharge pressure. The standard valve pressure rating is 28 kPa (400 psi).

Extreme Low Temperature Kit (Direct Expansion units only)

Extreme Low Temperature Kits for air cooled condensers are available for operation below –34.4°C (–30°F). The optional kit consists of pressure control valves and receivers for the liquid return side of the refrigerant piping.
