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.
