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 bearings 

and motor cooled by suction gas. 

- All compressor components are easily accessible on site 

minimising down-time. 

- Electronic motor protection against overloads and power 

supply 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 a 

corrosion resistance that is 3.5 times higher than that of 

traditional coils or coils with copper tubes and aluminium 

fins. 

■ Evaporator

resistance against outside aggression (mechanical and UV 

protection). 

■ 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, the 

condenser coil is fouled or if there is a fan fault, the 

Aquaforce 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

simulation tools (finite element calculation) for the design 

of critical components. 

- Transport simulation test in the laboratory on a vibrating 

table. The test is based on a military standard and 

equivalent to 4000 km by truck. 

- Salt mist corrosion resistance test in the laboratory for 

increased corrosion resistance. 

Pro-Dialog control 

Pro-Dialog combines intelligence with operating simplicity. 

The control constantly monitors all machine parameters and 

precisely manages the operation of compressors, electronic 

expansion devices, fans and of the evaporator water pump for 

optimum energy efficiency. 

■ 

■

- 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-over 

in 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. The 

information is in clear text and can be displayed in local 

language (please contact your distributor). 

Remote management (standard) 

Aquaforce is equipped with an RS485 serial port that offers 

multiple remote control, monitoring and diagnostic 

possibilities. Carrier offers a vast choice of control products, 

specially designed to control, manage and supervise the 

operation of an air conditioning system. Please consult your 

Carrier representative for more information. 

Aquaforce also communicates with other building 

management systems via optional communication gateways. 

A connection terminal allows remote control of the 

Aquaforce 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 over 

to the other pump 

- Operation indication: this volt-free contact indicates that 

the chiller is operating (cooling load) or that it is ready to 

operate (no cooling load) 

- Alert indication: this volt-free contact indicates the need to 

carry out a maintenance operation or the presence of a 

minor fault 

- Alarm indication: this volt-free contact indicates the 

presence of a major fault that has led to the shut-down of 

one or several refrigerant circuits 

* not available for units with the hydronic module option

Remote management (EMM option) 

The Energy Management Module offers extended remote 

control 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 specific 

alarm 

- Ice storage end: when ice storage has finished, this input 

permits return to the second set-point (unoccupied mode) 

- Compressor operation: indicates the operation of the 

compressors in refrigerant circuits A, B and C 

- Time schedule override: closing of this contact cancels the 

time schedule effects 

- Out of service: this signal indicates that the chiller is 

completely out of service 

- Chiller capacity: this analogue output (0-10 V) gives an 

immediate indication of the chiller capacity 

New generation 06T screw compressor 

The new generation of the Carrier 06T screw compressors 

benefits from Carrier’s long experience in the development of 

twin-rotor screw compressors. The compressor is equipped 

with bearings with oversized rollers, oil pressure lubricated 

for reliable and durable operation, even at maximum load. 

A variable control valve controlled by the oil pressure 

permits infinitely variable cooling capacity. This system 

allows optimal adjustment of the compressor cooling 

capacity and ensures exceptionally high stability of the 

chilled water leaving temperature. 

Among the other advantages: if a fault occurs e.g. if the 

condenser is fouled or at very high outside temperature, the 

compressor does not switch off, but continues operation with 

a reduced capacity (unloaded mode). 

The compressor is equipped with a separate oil separator that 

minimises the amount of oil in circulation in the refrigerant 

circuit and with its integrated silencer considerably reduces 

discharge gas pulsations for much quieter operation.

All aluminium micro-channel heat exchanger (MCHX) 

Already utilised in the automobile and aeronautical industries 

for many years, the MCHX used in the Aquaforce is entirely 

made of aluminium. This one-piece concept significantly 

increases its corrosion resistance by eliminating the galvanic 

currents that are created when two different metals (copper 

and aluminium) come into contact in a saline or corrosive 

atmosphere. 

From an energy efficiency point-of-view the MCHX heat 

exchanger is approximately 10% more efficient than a 

traditional coil and allows a 30% reduction in the amount of 

refrigerant used in the chiller. The low thickness of the 

MCHX reduces air pressure losses by 50% and makes it less 

susceptible to fouling by sand than a traditional coil. 

Cleaning of the MCHX heat exchanger is very fast using a 

high-pressure washer. 

Pro-Dialog operator interface with touch-screen 

The Aquaforce operator interface is very user-friendly. It is a 

large-format touch-screen, and the information is easily 

accessible: clear text in the selected language allows 

consultation of all operating parameters. Up to eight screens 

can be personalised.

Electrical data notes 

• 30XA 252-1002 units have a single power connection point located 

immediately upstream of the two main disconnect switches. 

• 30XA 1102-1702 units have two power connection points located upstream 

of 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 full 

accordance with all applicable local codes. 

• The Carrier 30XA units are designed and built to ensure conformance with 

these codes. The recommendations of European standard EN 60 204-1 

(corresponds to IEC 60204-1) (machine safety - electrical machine 

components - part 1: general regulations) are specifically taken into 

account, 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 EN 

60204 is the best means of ensuring compliance with the Machines 

Directive § 1.5.1. 

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

operation 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 (corresponds 

to 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 network 

monitoring elements, and it is recommended to create an IT type divider for 

the system units that require this and/or a TN type divider for Carrier units. 

Please consult the appropriate local organisations to define the monitoring 

and protection elements and carry out the electrical installation. 

NOTE: If particular aspects of an actual installation do not conform to the 

conditions described above, or if there are other conditions which should 

be considered, always contact your local Carrier representative. 

* The required protection level for this class is IP43B (according to reference 

document IEC 60529). All 30XA units are protected to IP54 and fulfil this 

protection condition.

Part load performances 

With the rapid increase in energy costs and the care about 

environmental impacts of electricity production, power 

consumption of air conditioning equipment has become an 

important topic. The energy efficiency of a liquid chiller at 

full load is rarely representative of the actual performance of 

the units, as on average a chiller works less than 5% of the 

time at full load. 

IPLV (in accordance with ARI 550/590-98) 

The IPLV (integrated part load value) allows evaluation of 

the average energy efficiency based on four operating 

conditions defined by the ARI (American Refrigeration 

Institute). The IPLV is the average weighted value of the 

energy efficiency ratios (EER) at different operating 

conditions, weighted by the operating time. 

The heat load of a building depends on many factors, such 

as the outside air temperature, the exposure to the sun and 

its occupation. 

Consequently it is preferable to use the average energy 

efficiency, calculated at several operating points that are 

representative for the unit utilisation. 

ESEER (in accordance with EUROVENT) 

The ESEER (European seasonal energy efficiency ratio) 

permits evaluation of the average energy efficiency at part 

load, 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 the 

operating time.
