Tandem Compressors
Comprising of 2 scroll type compressors linked together by refrigerant pipework to
one common circuit.
Tandem compressors provide variable control of the system performance by
activating individual compressors as required. Multiple steps of unloading allow
external load demands to be met with greater precision, eliminating unnecessary
temperature and humidity variations. Consequently, system efficiency and reliability
are much improved by extending major component working hours.
X and WX Models
Utilise a single hermetic scroll compressor fitted as standard with:
• Thermal motor protection internal or external (dependent upon model size)
• High temperature discharge protection
X2 and WX2 Models
Utilise a tandem hermetic scroll compressor set, to provide 2 stages of control, fitted
as standard with:
• Thermal motor protection internal or external (dependent upon model size)
• High temperature discharge protection
• Sight glass on common equalisation line.
