DESIGN FEATURES

FRAME/CABINET
Units are constructed with heliarc welded tubular steel frames. The tubular construction provides for maximum strength and ease of access. Side and front panels can be easily removed with quarter-turn fasteners allowing full access to all unit components. All panels include 1 inch thick, 11/2 pound density insulation for protection and sound attenuation.

FILTER SECTION
Units are provided with 4 inch deep, 30% efcient (based on ASHRAE Std. 52.1-1992), pleated lters. The lter section is accessible from the top or side on downow units and the right hand side on upow units.

REHEAT
Three stage electric reheat is standard. Lowwatt density, nned, tubular sheathed coils are constructed of stainless steel and provide ample capacity to maintain room dry bulb conditions during dehumidication. Low-watt density coils eliminate ionization associated with open air electric resistance heating.

COIL SECTION
Designed for draw through application, the computer selected dual circuited A-frame coil has an interwoven surface that increases unit efciency at low load conditions. Air is drawn through both circuits of the coil at low velocity providing effective surface exposure with minimum turbulence. Air bypass is provided to prevent saturated air from being introduced into the controlled space. The coil sits in a stainless steel drain pan.

HUMIDIFICATION
Data Aire Series units include an electric steam generator humidier with quick change disposable cylinders and auto-ush cycle. The steam generator humidier with its patented control system optimizes cylinder life and energy efciency by concentrating incoming water to a predetermined conductivity much higher than that of any entering water. The control system continuously monitors the conductivity in the cylinder through its electronics which allows water to be ushed as often as is necessary to maintain the capacity at this design conductivity. The high design conductivity results in a minimum ushing of heated water which saves energy. The humidier is designed to allow all units at any voltage to produce full rated steam output capacity at an optimum low water level based on this design conductivity.

FAN SECTION
The centrifugal, forward curved, double width, double inlet blower conguration is engineered for quiet reliable operation. The dual belt driven variable pitch drive section provides adjustable air ow capability to match the load requirements of the controlled space. The draw through design insures even air distribution across the coil, low internal cabinet pressure losses and static sealing of the lter section. Motors are mounted on an adjustable slide base and have internal overload protection.

REFRIGERATION CIRCUITS

Dual refrigeration circuits include high efciency hermetic scroll type compressors. Scroll compressors represent new yet proven compressor technology. Scroll compressors offer a combination of reliability, performance, and efciency. System noise is inherently quieter with scroll compressors. Scroll compressors offer: Simplicity - Fewer parts. Two components, a xed scroll and orbiting scroll, replace approximately 15 parts required to do the same work. Improved Starting Ability - With the scroll design the internal compression components always start unloaded even if the system pressures are not balanced. Since internal compressor pressures are always balanced at start-up, low voltage characteristics are excellent for scroll compressors. Energy Efciency - Scroll compressors are at least 10% more efcient than reciprocating type compressors. The suction and discharge processes of a scroll compressor are physically separated. This reduces heat transfer between the suction and discharge gas. In a piston type compressor the cylinder is exposed to both suction and discharge gas. This results in high heat transfer reducing the compressor efciency. Scroll compressor compression and discharge processes are very smooth. Gas is compressed in approximately 11/2 revolutions compared to less than 1/2 revolution for a piston. Scrolls require no valves. Piston compressors require both suction and discharge valves. No valves, no valve losses. Durability - Signicant design effort and system cost are required to protect piston compressors from slugging and debris. Scroll compressors are designed to be more tolerant of both liquid and debris. Reliability - Scrolls contain fewer moving parts resulting in greater reliability. Proven performance means fewer maintenance calls for eld personnel. Lower Sound - Systems properly designed with scroll compressors will be inherently quieter. On average, the compressor is up to 5 decibels quieter. (Sound characteristics of a scroll compressor are different than that of a reciprocating compressor. These do not effect system performance or reliability) These durable, heavy duty compressors have no gaskets or seals, eliminating the possibility of refrigerant or oil leaking into the controlled space or environment. Each refrigeration circuit includes built-in compressor overload protection, crankcase heater, lter drier, sight glass, adjustable expansion valve with external equalizer, low pressure override timer (air cooled units), manual reset high pressure control, and anti-short cycle timer. Water/glycol cooled units include counterow condensers sized to provide the required capacity for heat rejection with minimum water/glycol ow and total pressure drop.

The industrial duty condenser design includes an aluminum housing, aluminum nned copper tube coils, powder coated fan guards, energy efcient, thermally protected direct drive motors, and variable speed fan control on the lead motor for proper control down to -20 F. Additional fan motors are controlled with ambient thermostats. Air Cooled with Indoor Condenser A wide range of oor mounted indoor condensers with horizontal intake and discharge are available for applications where an outdoor condenser cannot be used. Finished to match the indoor evaporator section, the condenser includes a centrifugal, forward curved, double width, double inlet blower engineered for quiet and reliable operation. The belt driven variable pitch drive section provides adjustable airow. The motor has internal overload protection and is mounted on an adjustable slide base. Indoor condensers are provided with a factory mounted and piped receiver. The receiver has a head pressure control valve to maintain ooded condenser control. Air Cooled with Remote Outdoor Condensing Unit When compressors are required to be out of the controlled space, Data Aire Series units are available with a remote outdoor condensing unit. The condensing unit includes the compressors with built-in overload protection, crankcase heater, lter drier, sight glass, and condenser coil. The

OPTIONS

Energy Saver Coil - The Data Aire Energy Saver Coil is built into the system to provide total required capacity. Whenever the incoming water/glycol temperature is below 45o F/7.2o C, Energy Saver cooling is available. Energy Saver mode operates in the following range: return air setpoint plus deadband plus 2 degrees. The Energy Saver will operate providing there is a need for cooling. The valve will open at setpoint plus deadband. The valve will modulate as long as the space is between setpoint plus deadband plus 2 degrees. If the temperature falls below the deadband minus setpoint, the valve will close and the space is considered satised. While still in Energy Saver with the valve modulating, if the temperature goes beyond setpoint plus 2 degrees, the Energy Saver valve will close and DX cooling will begin. The Energy Saver coil includes the next size motor, 3-way pressure control valve on the condenser water circuit, and 3-way valve on the economy coil. Common piping for coil and condensers is provided. Energy Saver/Compressor Supplement - Units with Energy Saver option can be provided with compressor supplement if the Energy Saver is not sufcient as a stand alone system. When the incoming water/glycol temperature is below the setpoint of the water changeover thermostat, the Energy Saver is enabled (even if there is no call for cooling). Upon a call for cooling (setpoint plus deadband), the valve will open proportionally - 10% for each 0.1o above setpoint plus deadband. The compressor will come on at setpoint plus deadband plus 1o (the valve is 100% open at this point). The compressor will go off at setpoint plus deadband plus 0.7o. The valve will close proportionally - 10% for each 0.1o below setpoint plus deadband. An air discharge sensor is factory installed.

Auxiliary Chilled Water Coil - Where an existing chilled water loop is available, units can be tted with an auxiliary chilled water coil. Units will operate using the chilled water for cooling. Upon a loss of water ow or an increase in room temperature the system will bring on compressor (DX) cooling. The Auxiliary Chilled Water coil includes the next size motor. Separate piping is provided for the chilled water coil and refrigeration connections. Auxiliary Chilled Water Coil/Compressor Supplement - The Auxiliary Chilled Water Coil can be provided with compressor supplement for extended savings by allowing the compressor to supplement operation as needed when the chilled water is not sufcient on a stand alone basis. An air discharge sensor is factory installed. (See Energy Saver/Compressor Supplement for details)

Remote Temperature and Humidity Sensors - Temperature and humidity sensors may be ordered for remote wall mounting. Sensors are provided in a wall mount plastic case for remote sensing of temperature and humidity. 25 feet of shielded cable is provided for eld wiring. Smoke Detector - A unit mounted smoke detector will shut down the unit if smoke is sensed. The unit mounted microprocessor control will sound an alarm and display a SMOKE DETECTED message. The smoke detector is mounted in the return air stream and is provided with auxiliary contacts. Unit Mounted Disconnect - A unit mounted nonautomatic disconnect switch is installed in the high voltage electrical section. The operating mechanism (handle) protrudes through the decorative exterior panel. The operating mechanism prevents access to the high voltage electrical components by not allowing entry until switched to the OFF position.

OPTIONS, continued

Tandem Scroll Compressors - Units may be ordered with tandem scroll compressors when four stage compressor control is required. Units remain dual circuited. Tandem scrolls offer the inherent advantages of scroll technology: higher efciency, increased reliability, lower sound, and excellent liquid handling. Scroll tandems offer two steps of modulation so that one or both compressors (per circuit) can run depending upon the load of the system, resulting in part-load efciency equal to full load efciency. Two-step modulation is possible because of a carefully designed tubing conguration and the scrolls superior ability to tolerate liquid. The built-in discharge check valve, present in all scroll compressors, effectively prevents liquid migration in the off compressor. Oil migration is controlled with two specially designed oil and gas equalization lines. Adding this option to 30ton unit will increase cabinet size to 144. (See Supplement TS1-99: Tandem Scroll Technical Performance) Semi-Hermetic Compressors - Cast iron semihermetic compressors are available on all Data Aire Series units. Semi-hermetic compressors are mounted on vibration isolators and have builtin overload protection. The compressors also include oil sight glass, reversible oil pump for forced feed lubrication, and suction line strainer. Units with semi-hermetic compressor option also include solenoid valves and mufers. Maximum rpm is 1750. Four Step Control (Cylinder Unloading) - Units with semi-hermetic compressors may be ordered with four step control for periods of low load conditions. Cylinder unloaders on one head of each compressor reduces compressor cooling capacity. Four steps of cooling are available to meet changing room conditions. Compressor Sequence: Step 1 Lead compressor starts with unloader valve activated Step 2 Lead compressor running at full load Step 3 Lag compressor starts with unloader valve activated Step 3 Lag compressor running at full load 11

Hot Gas Bypass - Hot gas bypass is available for changing load conditions. The hot gas bypass valve is installed between the compressor discharge line and the leaving side of the expansion valve through a side outlet distributor. The system with the evaporator under full load will maintain pressure on the leaving side of the hot gas bypass valve to keep the valve port closed. Should the load on the evaporator decrease to the point where the coil is below the desired setting, the pressure on the discharge of the hot gas bypass will put pressure on the diaphragm overcoming the spring pressure of the seat and allowing some hot gas to mix with the normal liquid discharge of the expansion valve raising the evaporator pressure. This reduces the cooling capacity of the unit to match the load. The hot gas bypass valve can be adjusted to ne tune the unit to room conditions. Humidier Modulating Control - Modulating control may be added to the units steam generator humidier. Modulating control will allow the humidier to match its output to the signal from the humidity control. A self-regulating auto ush is included. Hot Water Reheat - Where hot water is available, a water coil for reheat is offered. The coil is designed for 150 psi maximum water pressure and includes a 2-way valve (a 3-way is also available). Units with the hot water reheat do not include electric reheat. Supplemental reheat may be ordered. Hot Gas Reheat - The units hot gas discharge may be used for reheat and maximum system efciency. Supplemental electric reheat may be ordered in addition to the hot gas reheat. 3-Way Water Regulating Valve - 3-way water regulating valves are available on water and glycol cooled units to replace the standard 2-way valve. The 3-way valve controls the water/glycol ow rate to maintain the required capacity under varying conditions. This option is recommended on units with dual pump applications.

OPTIONS, continued

Upow Air Discharge Plenum - Upow air discharge plenums are fully insulated with front discharge grille. Side grilles for both or one side are available. Plenums are 18 high and painted to match the units color. Floorstands - Floorstands are adjustable ( 2 inches) and may be ordered with factory installed turning vane or with seismic construction. High Efciency Filters - Standard lters are rated at 30% (per ASHRAE Std. 52-76). Higher efciency lters are available (consult factory regarding efciency percentage and unit static pressures). Condensate Pumps - Condensate pumps may be ordered factory installed or shipped loose for eld installation. Condensate pumps are complete with sump, motor, and automatic control. Pumps shipped loose are available in 115, 230, or 460 volts. Pump Ratings: 230 volt: with check valve - 40 GPH at 20 feet without check valve - 130 GPH at 40 feet 460 volt: with check valve - 50 GPH at 20 feet without check valve - 270 GPH at 40 feet Pump Package - Centrifugal pump packages are available to circulate water or water/glycol solutions. Pumps are available in various horsepower and voltages. Both 3400 and 1750 rpm pumps are available as an option. On dual pump applicatons it is recommended that a 3-way water regulating valve be used in lieu of the standard 2-way valve. Pump Enclosure - Pump enclosures are available for either single or dual pump applications. Pump enclosures are vented and weather resistant. When ordered with pumps, the pumps are factory mounted in the enclosure ready for eld piping and wiring. 12

Integral Pump Enclosures - Pumps may be factory mounted as an integral part of the dry cooler. A 30 extension is added to the dry cooler. Pumps are pre-piped and wired and includes shut-off valves. A ow switch is included with dual pumps. Pump Auto-Changeover - Dual pump packages may be provided with a pump auto-changeover control and NEMA 4 ow switch (eld installed). The pump auto-changeover control is factory wired and mounted in the dry cooler control box. The pump auto-changeover control provides automatic pump changeover in the event of a pump failure. Upon pump changeover, an audible alarm will sound at the indoor unit and a message (STANDBY PUMP ON) will be displayed on the indoor unit microprocessor display. Extended Compressor Warranty - Extended compressor warranties are available from Data Aire. Contact your local representative for one that best suites your needs.
