Graphic Display
Is an electronic device it allows complete management of graphics by the display of icons (defined at application software development level), the management of international fonts, and acoustic signal through piezoelectric buzzer as well.
The application software resides on the pPC controller therefore the terminal does not require any additional software for operation. Furthermore, the terminals feature a wide operating temperature range (-20 To 60 °C), the index of protection of the front panel of IP65.

Control System

• pPC is a microprocessor-based electronic controller developed by CAREL in compliance with the European RoHS directives.
• It provides a solution for many applications in the air-conditioning and refrigeration sectors and ensures absolute versatility.
• μPC runs the control program and is fitted with the set of terminals required for the connection to the devices(compressors, fans…).
• Which combines more functions including the RS-485 communication interface for option, delivering stronger performance, utility, standardization, convenience, and universality.
• The best performance of the cooling circuit thanks to PID superheat control.

Heat Exchanger
Shell &Tubes heat exchanger features a simple design that allows one fluid to run through the inner tubes while another fluid flows through the shell to transfer heat efficiently.
Shell &Tubes are designed specifically for refrigerant evaporate(DX Cooler) and condensing(Condenser) to heat exchange with water. Enhancements on the outside and the inside produce exceptional performance and efficiency.
Shell &Tubes are designed to provide excellent heat transfer rates, Quality insulation to prevent heat loss.
Shell circuits are designed to provide high performance with a low-pressure drop to conserve the required pumping power.
Simplified water connection, male pipe thread connections on the evaporator and female pipe thread connections on the condenser.

• Compact size for easy maintenance.
• Female Pipe Thread connections on the evaporator and condenser.
• Practical reference marks for entering and leaving water connections.
• Low-pressure drop to conserve the required pumping power.
• Fast commissioning.

Note :

• Multi-system water lines are applied to large projects and generally designed to realize area-based water supply. If some areas are being overhauled or cbsed, the bads may change significantly, so any unit can be turned off for the purpose of energy conservation.
• After the water system of the unit is installed, cbse the service valves 1 and 2 and open service valve 5; start the water pump; then wash the water filter; after the water line system is clean, connect the water pipe to the main machine to be ready for normal operation.
• Water pumps shall be selected according to the water fbw and required pump head and can be installed on the inlet and outlet header pipes. When the inlet pressure exceeds 1.0 MPa, they are recommended to be installed on the outlet pipe. The pump control shall be interbcked with the unit.
• The automatic differential pressure regulator can facilitate a more stable operation of the whole system.
• The automatic differential pressure regulator can facilitate a more stable operation of the whole system.
• Each inlet branch pipe of units shall be equipped with water regulating valve to albw water to fbw into units at a consistent rate.
• To ensure balanced water resistance, units shall be subject to equal-length installation.
• The valves 1, 2, 3, and 4 shall be used as service valves while valve 5 shall be used when the pipes shall be cleaned for initial system commissioning or when the terminals and pipes are subject to water treatment. In such cases, valves 1 and 2 shall be closed while valves 3, 4 and 5 shall be opened and the water pump shall be started
