RWC 10AX WATER CHILLER KW 12 WITH PUMP AND HERMETIC TANK

Description

REFRIGERATION UNIT MOD. ‘RWC 10 ax’:
12 kWf (10300 Frig/h) with outlet water temp. 15°C, ambient air temp. +25°C nominal output

REFRIGERANT CIRCUIT
COMPRESSOR/I: hermetic orbiting spiral type (Scroll)
FAN: axial EC (Electronic Control) BRUSHLESS type
THERMOSTATIC VALVE: electronic, regulates the injection of R410A into the evaporator
CONDENSER: high-efficiency aluminium microchannel pack
EVAPORATOR: AISI 316 STAINLESS STEEL plate or tube bundle plus closed-cell foam insulation
CONNECTION PIPE: copper/plastic
GAS LOAD: performed with appropriate refrigerant gas for each capacity
OIL LOAD: checked during testing, does not require topping up or periodic replacement
GAS TYPE: R410A Ecological
INDIC. LIQUIDITY AND HUMIDITY INDICATOR: allows verification of both moisture content and sufficient gas flow in the circuit
AIR FILTER: in double-layer corrugated aluminium mesh that can be removed and cleaned
DEHYDRATING FILTER: solid cartridge with high dehydrating capacity
HIGH PRESSURE SENSOR: fan control/management, max. gas pressure safety with alarm signal/compressor lockout
LOW PRESSURE SENSOR: minimum gas pressure control with alarm signal/compressor cut-out

HYDRAULIC CIRCUIT
HERMETIC TANK: galvanised steel, heat-insulated
ELECTRIC PUMP: centrifugal stainless steel Aisi 304, aluminium motor case, class F insulation, IP 55 protection degree
PUMP EXCLUSION SHUTTER: exclusion gate on suction side
PUMP PRESSURE GAUGE: pressure gauge for reading the operating pressure on the discharge side.
FLOW SWITCH: controls sufficient water flow to the evaporator with alarm signal and compressor blockage
NON-REFLECTION VALVE (where fitted): mounted on the discharge of the pump
WATER FILTERS (where fitted): prevent fouling of the evaporator.

ELECTRICAL EQUIPMENT
ELECTRONIC MICROPROCESSOR OF THE HYDRAULIC CIRCUIT AND REFRIGERANT CIRCUIT: with the function of thermostatting the liquid in the circuit. Two probes detect both the inlet and outlet temperatures. Both are shown on the display. The user can only program the outlet temperature via the keypad on the front of the microprocessor. In models with several compressors, ‘rotation’ management of the compressors is realised, in order to guarantee an equal number of working hours for all components. Another display shows with scrolling texts (5 languages to choose from) the chiller's operating ‘status’, any faults or maintenance precautions, refrigerant gas working pressures, with the possibility of remote diagnosis.
