1. GENERAL INFORMATION
1.1 TECHNICAL FEATURES
STRUCTURE
The supporting frame and removable panels are made of metal sheet painted with epoxy powder with an orange peel
texture, and are only suitable for indoor installation. If an outdoor application is necessary, the Outdoor OD accessory is
required, which involves the use of galvanized steel sheet, further coated with polyester powder at 180 °C which confers a
high resistance to atmospheric agents. Stainless steel screws.
ELECTRO-PUMPS
Monobloc centrifugal electric pumps are used with a motor and pump unit directly coupled through a chrome steel single
shaft. Cast iron body and rotor, ceramic/carbon/EPDM mechanical seals suitable for use with ethylene glycol, and 2-pole,
three-phase electric motor with an IP 54 electrical protection degree.
If the double pump accessory is available, the two electro-pumps will be arranged in parallel and operate alternatively: if an
alarm is triggered due to the malfunction of one of the pumps, the other pump will automatically be activated.
The pumps are variable in speed by means of an inverter, and controlled with a signal from the pressure transducers in the
hydraulic circuit.
The inverters are assembled on the machine, and each pump unit (primary and secondary) is adjusted by a specific inverter.
TANK
The tank is only included by standard in the version with glycols.
Hot galvanized iron tank insulated with 13 mm thick polyurethane foam covered in PVC.
HYDRAULIC CIRCUIT
The indoor hydraulic circuit consists of flexible rubber or steel pipes, galvanized iron pipe fittings, check valves, stop valves,
valves for discharging the air found in the hydraulic circuits, an expansion tank , and a motorised 2 way valve with actuator
and pressure transducers.
ELECTRIC CONTROL BOARD (standard units)
The electric control board with IP X4 protection class includes:
– a main isolating switch
– pump magnet circuit-breaker switches
– pump contactors
– speed governor with a three-phase inverter for each hydraulic circuit pump
– magnet circuit breaker switches to protect the inverter/s
– control module (IQnomic) for the management of I/O signals coming from loads
– an isolating transformer
– a cooling fan
1.2 THE SERIES
AQUA Link
The AQUA Link hydraulic equipment series for indoor or outdoor housing is available in various sizes in combination with a
chiller whose total rated power varies from 90 to 300 kW.
As for the utilities side, the sizing of the unit is designed to allow it to be combined to systems providing for a subdivision in
the use of the total power output of the chiller as shown in the following table
