The 30HXC units are water-cooled chillers, designed from the ground up to meet the needs of today and tomorrow. Itis distinguished for its chlorine-free refrigerant, high efficiency, high reliability, easy maintenance and low running cost.Born in 1990s, 30HXC is widely applied in all kinds of buildings such as hotels, offices, restaurants, schools, hospitals,enterprises, etc.
= R134a has zero ozone depletion potential.= R134a production is annually increasing, and has no expire date.
Designed exclusively for R134a
30HXC1
= 06N twin-screw compressor achieves high efficiency.= Carrier patent high efficiency flood evaporator increase heat transfer efficiency.= Multiple compressors allow flexible adjustment according to user's load, ensuring higher part-load efficiency.= Electronic expansion valve ensures high control precision.
Full/part load mode is more cost saving
Two independent refrigerant circuits minimize unit shut down. Multiple compressors provide back up for each other. Complete protection function ensures the unit running smooth. Each unit has a trial run in the factory.
High reliability
Built-in sound reduction device can effectively reduce noises as result of high pressure air discharge fluttering by diverting the air in an appropriate way.
New external muffler installed on the discharge pipe on the compressor can transform part of acoustic energy into heat and greatly reduce noise. (See the picture below)
Sound reduction cabinet provides another sound-proofing barrier, and reduces the noise transferring to the machine room. (See the picture below)
Triple Sound Reduction
Graphical operational interface makes it clear and easy to operate. Screw compressor with few components requires low maintenance cost.
Simple to service
Compact design requires minimal indoor space. The maximum width reaches only 1015mm, which allows the unit to fit through a standard door
opening without disassembly. Evaporator and condenser short steel pipes and flanges are supplied by factory. Refrigeration and lubrication is filled ex-factory. The on-site installation requires only connection to water and power supply.
Easy installation

PRO-DIALOG Plus is an advanced nu-meric control system that combines in-telligence with great operating simplicity.The PID control algorithm with perma-nent compensation for the difference be-tween the heat exchanger entering andleaving temperature, anticipates loadvariations, guarantees leaving watertemperature stability and prevent unnec-essary compressor cycling.

Multiple remote control
�=The communication bus between RS485 port of 30HXC and the Carrier Comfort Net (need purchase) offers multiple remote
control; the communication bus between 30HXC and DATAPORT communication module provided by Carrier (need purchase)
realizes the connection with other building automatics.
Safety Protection Function
�=Protection on low cooling water leaving temperature, low oil pressure, high refrigerant pressure, electric leak, compressor
overload, high/low electrical voltage and phase lack.
PRO-DIALOG has advanced control functions
�=Allows local mode, remote mode and CCN mode to start/stop the unit.
�=The long-stroke electronic expansion valve (EXV), allows a significant energy efficiency improvement at part load conditions,
and faultless chiller operation in a wider temperature range.
�=Automatic control of refrigerant circuits and compressors on/off status and loading sequence, thus equalizing compressor
operating hours.
�=Interlock control between the unit, chilled water pump and cooling water pump, contributing to safe and high efficiency
performance.
�= "Demand Limit" limits the maximum chiller capacity to a predefined value. This function is specially designed for multi-
compressor management, it aims to achieve the best running efficiency by imposing different chiller capacity limit to different
compressors.
�=Evaporator leaving water temperature drop speed is controlled within the adjustable range (0.1~1.1°C/min) so as to avoid
energy waste, improve ERR and increase unit life.
�=Provides a negative revision to cooling water leaving temperature according to outdoor temperature or return water tempera
ture trend, so as to save energy and improve ERR by quickly fitting the wave trend of external load decrease.
PRO-DIALOG offers extended communications capabilities
�=Graphical interface, LED numeric displays make it clear and easy to understand.
�=Touch keys are well-positioned on the schematic chiller diagram, providing clear view of operation flow. All operating
parameters such as pressures, temperatures, operating hours etc are easy to use.
�=Operating menus provide direct access to acquiring and modifying parameters.
