Technical specifications
Compressor can be sized on peak load, for best
applied cost, or optimal efficiency. For optimal
efficiency, see our performance details in
Coolselector software.
Compressor size
Different frequency converter variants are
available according to:
1. Mains supply voltage
2. IP class (CDS303 drives are available in IP20 or
IP55 housings)
3. RFI (Radio Frequency Interference) class H2/H3
or HX
4. Printed Circuit Board (PCB) coated or not
coated.
When the compressor size and mains voltage
have been defined in the above selection criteria,
the code number tables from the “Ordering
information and packaging” section provides the
appropriate frequency converter sizes and up
to eight corresponding code numbers for each
compressor model.
Note this compressor is equipped with
a four poles electrical motor so the applied
frequency from the inverter will be 50 Hz for
25 rps (1500 rpm) up to 200 Hz for 100 rps
(6000 rpm).

Oil injection An oil injection system is integrated into the VZH
compressors for improved sealing of the scroll
pockets during compression thus improving
its isotropic efficiency while also controlling
the amount of oil circulated into the system (oil
circulation ratio).
This system is controlled through the frequency
converter and preconfigured on relay_1.
The oil injection is ON at low speed and OFF at
high speed. The preset speed values are shown
on following table
Internally, the solenoid valve is bypassing the oil
injection
Oil injection is ENABLED when solenoid valve
coil IS NOT power supplied (Below oil injection
speed)
Oil injection is DISABLED when solenoid valve
coil IS power supplied (Above oil injection speed)
The compressors are delivered without the coil.
They are available in 208-240Vac, 110-120Vac or
24Vac and the ordering code numbers are in the
ordering information section.

Technical specifications
OIL level sensor A TEKLAB LC-XN optical-electrical level sensor
is fixed on the inverter compressor. The oil level
sensor prism is fixed on the compressor, the
electrical part is ordered by accessory kit. The oil
level sensor monitors the compressor oil level
and sends oil level signal to an external relay or
digital input of unit controller. A 5±2 seconds
delay is recommended to mitigate oil level
fluctuationand avoid false alarms.
- Lack of oil: Circuit between 2 and 3 will be
opened internally, there will be no current
flowing through load or coil of external relay,
relay is open.
- Enough oil: Circuit between 2 and 3 will be
closed internally, there will be current flowing
through load or coil of external relay, relay is
close.
Note: For 24VDC, output voltage in case of lack
of oil is >13V DC and not 0V
For customers who needs UL certificates, please
order 24V AC/DC sensor.
