2. FEATURES As a result of Carrier continuous development, 30RM Series water chillers, have been carefully designed and manufactured under strict quality conditions to give you full satisfaction through efficient operation with minimum maintenance and service. Carrier 30RM series were born of a very simple concept: " An excellent product isn't enough; it must offer more than its competitors ". In addition to true cooling, Carrier 30RM series have advanced features and performance level, which our competitors will find difficult to equal, maintaining the same quality/ price ratio. TAKE A LOOK AT THESE FEATURES

TRUE POWERFUL COOLING - Enhanced cooling capacity delivers more comfort

than competitors. 30RM efficient compressors lead to true unit cooling Performance.

- The declared capacity of the unit conforms with ARI standard which ensure highest level of cooling capacity to be maintained long time period.

MINIMUM SOUND AND VIBRATIONS - By using scroll compressors, Carrier has become the

pioneer in the anti-noise battle. The orbital movement of scroll compressors ensures

a more balanced compression, generating fewer vibrations and thus less noise

- The compressor chassis is isolated from the unit by

flexible anti-vibration mountings to limit noise transmission.

- Following extensive thermal and acoustic studies,

Carrier selected the transverse V-shape for condenser coils with an angle which allows even circulation over the complete coil surface low velocity for maximum efficiency and minimal noise generation.

QUALITY, RELIABILITY AND SAFETY - All materials included in Carrier air cooled 30RM water

chillers units conform with the international standards of safety, performance and reliability.

- Quality is ensured through receiving inspection testing

and through all stages of manufacturing, sales, installation

and servicing to finally ensure customer full satisfaction according to ISO 9001 Quality System.

TROPICALLIZED Carrier 30RM water chillers are designed to work in very high ambient temperatures up to 52oC due to efficient compressor, and condenser coils. LONG LIFE, CORROSION RESISTANT AND SOLID CONSTRUCTION * Weather proof made of chemically treated,

galvanized steel sheet metal. * Powder painted with perfect adhesion of a

highly resistant polyester paint. * Components are suitable for any climate. OPERATING LIMITS

Temperature °C Minimum Maximum Leaving Water 5°C 10°C Outdoor 19°C 52°C

COMPACT DESIGN AND LIGHT WEIGHT

Units occupies limited space and has reduced weight.

LOW INSTALLATION COST

Units are designed to provide high efficiency anddependable operation for many years. They are delivered factory wired, charged, and tested. Their installation requires followings connections: electrical power supply to thermostat and eventually interconnecting refrigerant piping. The control box is fully wired according to European codes. Only the installation of an isolator / fuses and connections to the power supply is required at the installation location.

FEATURES (Cont.)

EASY INSTALLATION, SERVIECE AND MAINTENANCE

- The units are accessible from all sides. Excellent compressor(s) access and removal if necessary.

- The control panel is located in a separate

compartment and can be inspected without disturbing unit operation. Pumping down valves fitted in liquid lines to enable refrigerant to be temporarily stored in the condenser coil if the refrigerant is to be repaired or some part of the refrigeration system to be replaced.

- Rotalock suction and discharge valves fitted

on compressor for servicing. - The unit is completely factory assembled,

electrically wired, and charged with total R22 charge, tested against extreme conditions and quality control approved before leaving the factory.

- All compressors are equipped with a sight

glass to determine the amount and condition of the oil contained within the sump.

-

- The compressors SM185 are equipped with an oil drain connection to allow oil to be removed from the sump for changing oil, testing, etc.

-

SUPER SAFETY PROTECTIONS

- Dual high/low pressure control for compressor protection against high discharge, low suction pressures and refrigerant leak.

- 5 minutes time delay for compressor protection against

short cycling when power off or thermostat off. - 1 minute time delay for to avoid simultaneous starting

of two compressors. - Internal pressure relief valve for compressor protection

against high discharge pressures. - Crankcase heater to guard compressor against flood

back conditions and to eliminate oil fluffing on start up - Internal overloads for compressors protection against

excessive temperature and/or excessive current caused by overloading, low refrigeration flow, phase loss or incorrect of compressor motor.

- Internal overloads for fan/motors protection against

excessive temperature - External sensitive quick trip overloads for compressors

and motors protection against excessive current. These overloads mounted on definite purpose contactors of quite operation. - Anti freeze water thermostat. - Phase protector against phase reversal and phase loss. - Protection class for terminal box matches with

international standards of safety as follows: • IP54 for compressor (as per standard UEC529) • IP54 for fan / motor (as per standard IEC529)

- All electrical components are CE and UL approved

recognized.

9. CONSIDERATIONS FOR SELECTING INSTALLATION LOCATION

a. Location of Electrical Power Supply The electrical power supply should be close to the chiller unit to facilitate electrical wiring

connections and reduce length of electrical cables. b. Weight of chiller Unit The installation location of chiller unit should be able to support operating weight of chiller unit, and

not cause vibration. c. Effect of Direct Sunlight The installation location of chiller unit is preferable to be far away from the direct sunlight. d. Effect of heat sources, steam or flammable gas The installation location of chiller unit should be far away from heat sources, steam or flammable gas. e. Cleanness of location The installation location of chiller unit should be free of dust or any material, which can cause

clogging of condenser coil. When installing unit on the ground, select a location not subjected to flooding.
