TurboChill™ R513A Air Cooled and FreeCool
Turbocor Compressor
Each installed compressor comes with the following components:
●
Suction and discharge shut off valves.
●
Discharge non-return valve.
●
Line reactor (for removing additional impedance harmonics and voltage spikes in the ac waveform).
● EMI/EMC filter:
◦ AC-DC rectifier.
◦
DC capacitors.
◦ DC-AC (IGBT) converter.
◦
Motor/bearing management system and incorporated surge protection.
◦
Soft start module.
◦
Magnetic bearing system.
◦
Vibration reducing isolating rubber mounts.
◦
Linear capacity modulation is provided by a variable frequency drive.
Key benefits of Turbocor compressor technology:
● Oil Free Operation:
◦ More efficient heat exchange.
◦
No oil entrainment issues – pipe work can be optimised for performance not oil return.
●
Small and light, only 120kg or 132kg (compressor size dependant).
●
Turbocor compressor shaft and impellers levitate on a magnetic cushion eliminating friction and vibration resulting in
the compressor running at a smooth and reduced sound spectrum.
● The TurboChill compressor’s variable speed control offers 2 major benefits:
◦
Uses substantially less power at part load and gives accurate set-point control and exact capacity match.
◦
The inbuilt electronic soft start produces a very low starting current of just 2A and eradicates the need to
oversize electrical supply components on site.
