SUCTION LINES Designed for minimum friction loss and proper oil return. All suction lines are insulated with flexible closed cellhoses.CONDENSER COILS Made of seamless copper tubes expended onto aluminum fins. Copper fins and lacquered or anodized finsare also available on request. Size of pipes, number of rows, face area, etc., are in accordance with the compressor capacity,evaluated as per ARI standard code.CONDENSER FANS are direct driven propeller type. Blades are statically and dynamically balanced and run at low RPM for quietand vibration-free operation. Fan blades are protected by heavy gauge fan guards. On request a centrifugal forward curved typeblower can be supplied, statically and dynamically balanced, with parts made of galvanized steel sheet, driven directly or bybelts.FAN MOTORS are permanent split capacitor induction type or three phase type with inherent thermal protection. Motors havepermanently lubricated ball bearings and are of water proof enclosed type designed for service at ambient temperatures up to60 C, with additional moisture protection, making them suitable for outdoor conditions. Motors are suitable for horizontal andvertical working positions, and run at low speed, producing low noise, and are manufactured in accordance with most Europeanand American electric norms.COMPRESSORS. COPELAND semi hermetic compressors are used, refrigerant gas cooled type with built-in thermal protection,crankcase heater and large voltage capacity, suitable for 50 and 60 Hertz application. Each compressor is mounted on isolatorpads and connected via flexible — vibration — absorbers to the coil copper tubing to reduce vibration transmission to the rest ofthe unit. Compressors are designed for high energy efficiency, compact construction , rugged reliability, long-life and aremaintenance free. Compressors can be disassembled in the field for service.Oil level sight glass is standard. Oil electronic pressure control cuts the power to the motor when the pressure drops belowacceptable limits. Larger compressors have a built-in relief valve between suction and discharge lines which will open if themaximum permissible pressure differential is reached.EVAPORATOR is a shell and tube type cooler. The construction is in accordance with most American and European Norms andcodes (TEMA — RINA — ISPESL — TUV - SDM). Weather and corrosion resistant suitable for outdoor applications. Gas tubes aremade of seamless copper tubes and are tested at 28 bar (400 psig). Shell have standard trade water outlets for thermostat, airvent, drain and water main stream. This liquid cooler is also suitable as liquid heater in Heat pump mode.ECONOMIZER shell and tube type is available on request, it improves the chilling capacity of the unit, by precooling the chiller,and preheating the gas at the compressor suction line.ELECTRIC junction board shall be color coded and wires identified for easy field connections and maintenance. It includescompressor and fan motor contactors, thermal overload protection, high/low voltage and phase failure protectio, pressureprotection cut of relay with compressor restart delay, compressor crankcase heater relay, circuit fuse beakers, and codedterminals.
WATER PUMP can be included as an accessory according to client specifications. Thermometers and pressure gauges on theliquid inlet and outlet can be provided on reques. Air vents are standard.INSTALLATION of the unit is easy because it needs only to be connected to the outside utilities: liquid line and electric powersupply.ELECTRIC BOARD with remote control and functional display with duty lamps and alarms can be supplied.24 VAC transformer ready to connect electronic thermostat (optional).ACCESS to all internal parts for cleaning or maintenance, needs loosening of a few screws only to remove any pane. All parts canbe easily removed & replaced.COOLER Service Department is always available to serve our customer and ready to solve any problem.COOLER Project Department is ready to study cases and to supply the most economic, yet feasible solutions.QUALITY GUARANTEUNIC sal COOLER guarantees contractual free maintenance, availability of all parts and components, and qualified fieldtechnicians to carry out the maintenance requirements.UNIC sal Company is ISO 9001:2015, DQS-UL, IQNet and CE Certified.
