Aircooled direct expansion Dual Fluid units with Scroll compressors and EC Inverter Plug-Fans
TO 118 KW
TO 34 TON)
Aircooled direct expansion Dual Fluid units with double circuit: one aircooled direct expansion circuit and one chilled water circuit.
The circuits are separated, with non-simultaneous start-up, for back-up operation.
The TOP range features EC Inverter Plug-Fans; high ESP fans are also
available as accessory.
The EC Inverter Plug-Fans allow consumption reduction at partial loads up to 61% comparing to radial fans, with the modulation of absorbed power depending on the real thermal load.
The TOP range is available in two air discharge versions: TOPT with top air discharge and TOPB with bottom air discharge.
Unit supervision is developed by means of Modbus RTU protocol over RS485 serial interface as standard configuration. Other communication protocols and interfaces are available as option.
The units can operate at high ambient temperature (up to 52°C) with dedicated combination with remote condensers.
