Easy and fast installation■ Integrated hydronic module (option)

- Centrifugal low or high-pressure water pump (as required),based on the pressure loss of the hydronic installation

- Single or dual pump (as required) with operating timebalancing and automatic changeover to the back-up pump ifa fault develops

- Water filter protecting the water pump against circulatingdebris

- High-capacity membrane expansion tank ensurespressurisation of the water circuit

- Thermal insulation and aluminium protection- Pressure gauge to check filter pollution and measure the

system water flow rate- Water flow control valve

■ Simplified electrical connections- Main disconnect switch with high trip capacity- Transformer to supply the integrated control circuit

(400/24 V)■ Fast commissioning

- Systematic factory operation test before shipment- Quick-test function for step-by-step verification of the

instruments, expansion devices, fans and compressors

Environmental care■ R134a refrigerant

- Refrigerant of the HFC group with zero ozone depletionpotential

- 30% reduction in the refrigerant charge through the use ofmicro-channel heat exchangers

■ Leak-tight refrigerant circuit- Reduction of leaks as no capillary tubes and flare

connections are used- Verification of pressure transducers and temperature

sensors without transferring refrigerant charge- Discharge shut-off valve and liquid line service valve for

simplified maintenance.

Absolute reliability■ Screw compressors

- Industrial-type screw compressors with oversized bearingsand motor cooled by suction gas.

- All compressor components are easily accessible on siteminimising down-time.

- Electronic motor protection against overloads and powersupply faults (loss of phase, phase reversal).

■ Air condenser- The all aluminium micro-channel heat exchanger (MCHX)

is not very sensitive to fouling by sand and offers acorrosion resistance that is 3.5 times higher than that oftraditional coils or coils with copper tubes and aluminiumfins.

■ Evaporator- Thermal insulation with aluminium sheet finish for perfect

resistance against outside aggression (mechanical and UVprotection).

■ Auto-adaptive control- Control algorithm prevents excessive compressor cycling

(Carrier patent)- Automatic compressor unloading based on the condensing

pressure. If the outside temperature is too high, thecondenser coil is fouled or if there is a fan fault, theAquaforce continues to operate at a reduced capacity.

■ Control box with reinforced air tightness- Reinforced air tightness to protect against sand penetration

(protection level IP54)- Forced ventilation to prevent overheating of the electrical

components.■ Exceptional endurance tests

- Partnerships with specialised laboratories and use of limitsimulation tools (finite element calculation) for the designof critical components.

- Transport simulation test in the laboratory on a vibratingtable. The test is based on a military standard andequivalent to 4000 km by truck.

- Salt mist corrosion resistance test in the laboratory forincreased corrosion resistance.

Pro-Dialog controlPro-Dialog combines intelligence with operating simplicity.The control constantly monitors all machine parameters andprecisely manages the operation of compressors, electronicexpansion devices, fans and of the evaporator water pump foroptimum energy efficiency.

■ Energy management- Internal time schedule clock: controls chiller on/off times

and operation at a second set-point- Set-point reset based on the outside air temperature or the

return water temperature- Master/slave control of two chillers connected in parallel

with operating time equalisation and automatic change-overin case of a unit fault.

■ Ease-of-use- User interface with large touch screen (120 x 99 mm) for

intuitive access to the operating parameters. Theinformation is in clear text and can be displayed in locallanguage (please contact your distributor).

Remote management (standard)Aquaforce is equipped with an RS485 serial port that offersmultiple remote control, monitoring and diagnosticpossibilities. Carrier offers a vast choice of control products,specially designed to control, manage and supervise theoperation of an air conditioning system. Please consult yourCarrier representative for more information.

Aquaforce also communicates with other buildingmanagement systems via optional communication gateways.A connection terminal allows remote control of theAquaforce by wired cable:- Start/stop: opening of this contact will shut down the unit- Dual set-point: closing of this contact activates a second

set-point (example: unoccupied mode)- Demand limit: closing of this contact limits the maximum

chiller capacity to a predefined value- Heat reclaim (option): closing of this contact allows heat

reclaim mode operation- Water pump 1 and 2 control*: these outputs control the

contactors of one or two evaporator water pumps- Water pump on reversal*: these contacts are used to detect

a water pump operation fault and automatically change overto the other pump

- Operation indication: this volt-free contact indicates thatthe chiller is operating (cooling load) or that it is ready tooperate (no cooling load)

- Alert indication: this volt-free contact indicates the need tocarry out a maintenance operation or the presence of aminor fault

- Alarm indication: this volt-free contact indicates thepresence of a major fault that has led to the shut-down ofone or several refrigerant circuits

* not available for units with the hydronic module option

Remote management (EMM option)The Energy Management Module offers extended remotecontrol possibilities:- Room temperature: permits set-point reset based on the

building indoor air temperature (with Carrier thermostat)- Set point reset: ensures reset of the cooling set-point based

on a 4-20 mA or 0-5 V signal- Demand limit: permits limitation of the maximum chiller

power or current based on a 0-10 V signal- Demand limit 1 and 2: closing of these contacts limits the

maximum chiller power or current to two predefined values- User safety: this contact can be used for any customer

safety loop; opening of the contact generates a specificalarm

- Ice storage end: when ice storage has finished, this inputpermits return to the second set-point (unoccupied mode)

- Compressor operation: indicates the operation of thecompressors in refrigerant circuits A, B and C

- Time schedule override: closing of this contact cancels thetime schedule effects

- Out of service: this signal indicates that the chiller iscompletely out of service

- Chiller capacity: this analogue output (0-10 V) gives animmediate indication of the chiller capacity

New generation 06T screw compressor

The new generation of the Carrier 06T screw compressorsbenefits from Carrier’s long experience in the development oftwin-rotor screw compressors. The compressor is equippedwith bearings with oversized rollers, oil pressure lubricatedfor reliable and durable operation, even at maximum load.A variable control valve controlled by the oil pressurepermits infinitely variable cooling capacity. This systemallows optimal adjustment of the compressor coolingcapacity and ensures exceptionally high stability of thechilled water leaving temperature.

Among the other advantages: if a fault occurs e.g. if thecondenser is fouled or at very high outside temperature, thecompressor does not switch off, but continues operation witha reduced capacity (unloaded mode).

The compressor is equipped with a separate oil separator thatminimises the amount of oil in circulation in the refrigerantcircuit and with its integrated silencer considerably reducesdischarge gas pulsations for much quieter operation.

Already utilised in the automobile and aeronautical industriesfor many years, the MCHX used in the Aquaforce is entirelymade of aluminium. This one-piece concept significantlyincreases its corrosion resistance by eliminating the galvaniccurrents that are created when two different metals (copperand aluminium) come into contact in a saline or corrosiveatmosphere.

From an energy efficiency point-of-view the MCHX heatexchanger is approximately 10% more efficient than atraditional coil and allows a 30% reduction in the amount ofrefrigerant used in the chiller. The low thickness of theMCHX reduces air pressure losses by 50% and makes it lesssusceptible to fouling by sand than a traditional coil.Cleaning of the MCHX heat exchanger is very fast using ahigh-pressure washer.

Electrical data notes

• 30XA 252-1002 units have a single power connection point locatedimmediately upstream of the two main disconnect switches.

• 30XA 1102-1702 units have two power connection points located upstreamof the main disconnect switches.

• The control box includes: - One main disconnect switch per circuit- Starter and motor protection devices for each compressor, the fans and

the pump- Control devices

• Field connections:All connections to the system and the electrical installations must be in fullaccordance with all applicable local codes.

• The Carrier 30XA units are designed and built to ensure conformance withthese codes. The recommendations of European standard EN 60 204-1(corresponds to IEC 60204-1) (machine safety - electrical machinecomponents - part 1: general regulations) are specifically taken intoaccount, when designing the electrical equipment.

Notes:• Generally the recommendations of IEC 60364 are accepted as compliance

with the requirements of the installation directives. Conformance with EN60204 is the best means of ensuring compliance with the MachinesDirective § 1.5.1.

• Annex B of EN 60204-1 describes the electrical characteristics used for theoperation of the machines.

1. The operating environment for the 30XA units is specified below:• Environment* - Environment as classified in EN 60721 (corresponds to

IEC 60721) :- outdoor installation*- ambient temperature range: minimum temperature -20°C to +55°C,

class 4K4H*- altitude: lower than or equal to 2000 m- presence of hard solids, class 4S2 (no significant dust present)- presence of corrosive and polluting substances, class 4C2 (negligible)

2. Power supply frequency variation: ± 2 Hz.3. The neutral (N) line must not be connected directly to the unit (if necessary

use a transformer).4. Overcurrent protection of the power supply conductors is not provided with

the unit.5. The factory-installed disconnect switch(es)/circuit breaker(s) is (are) of a type

suitable for power interruption in accordance with EN 60947-3 (correspondsto IEC 60947-3).

6. The units are designed for simplified connection on TN(s) networks (IEC 60364). For IT networks derived currents may interfere with networkmonitoring elements, and it is recommended to create an IT type divider forthe system units that require this and/or a TN type divider for Carrier units.Please consult the appropriate local organisations to define the monitoringand protection elements and carry out the electrical installation.

NOTE: If particular aspects of an actual installation do not conform to theconditions described above, or if there are other conditions which shouldbe considered, always contact your local Carrier representative.

* The required protection level for this class is IP43B (according to referencedocument IEC 60529). All 30XA units are protected to IP54 and fulfil thisprotection condition.

With the rapid increase in energy costs and the care aboutenvironmental impacts of electricity production, powerconsumption of air conditioning equipment has become animportant topic. The energy efficiency of a liquid chiller atfull load is rarely representative of the actual performance ofthe units, as on average a chiller works less than 5% of thetime at full load.

IPLV (in accordance with ARI 550/590-98)The IPLV (integrated part load value) allows evaluation ofthe average energy efficiency based on four operatingconditions defined by the ARI (American RefrigerationInstitute). The IPLV is the average weighted value of theenergy efficiency ratios (EER) at different operatingconditions, weighted by the operating time.

IPLV (Integrated Part Load Value)Load Air temperature Energy Operating(%) (°C) efficiency time, %100 35 EER1 175 26.7 EER2 4250 18.3 EER3 4525 12.8 EER4 12

IPLV = EER1 x 1% + EER2 x 42% + EER3 x 45% + EER4 x 12%

The heat load of a building depends on many factors, suchas the outside air temperature, the exposure to the sun andits occupation.

Consequently it is preferable to use the average energyefficiency, calculated at several operating points that arerepresentative for the unit utilisation.

ESEER (in accordance with EUROVENT)The ESEER (European seasonal energy efficiency ratio)permits evaluation of the average energy efficiency at partload, based on four operating conditions defined by Eurovent.The ESEER is the average value of energy efficiency ratios(EER) at different operating conditions, weighted by theoperating time.
