Oil Injected, Two-Stage, Direct Coupled, Fixed/Variable Speed

Rotary Screw Air Compressors

Next gen compact compressors maximize your energy saving, minimize your total cost of own.

General Features

• IE4 efficiency-class electric motors in fixed speed models

• IE5 efficiency-class IPM electric motors in variable speed models

• Two-stage screw block

• Water cooling (37 kW and above)

• Variable and fixed speed motor power options

• Soft start with variable speed power transmission

• Heat recovery (optional)

• Operating with low noise level

• Integrated dryer (optional)

Screw Block

• Two-stage screw produces energy efficiency by up to 10%

• Higher flow rate by up to 10%.

• Thanks to low compression rate low axial and compression forces

• Zero transmission losses by compact direct power transmission

• No requirement for a power transmission element results in a compact design

• Low axial and compression forces due to low compression ratio between screw blocks

• Thanks to low rotor speeds, a long service life

• Thanks to two-stage compression, low noise and vibration levels

Electric Motor

In Fixed Speed Models;

• IE4 energy efficiency-class electric motors

• Optimised air cooling

• Motors have B-class temperature increase

In Variable Speed Models;

• Ultra Premium IE5 energy efficiency-class electric motors

• Internal Permanent Magnet Motor (IPM)

• Compact design

• F-class insulation

• Optimum oil cooling at all speeds for high efficiency

• Grease-free lubricated motor bearings

Electric Motor Drive*

• The drive and IPM meet the requirements of IES2 (EN50598)

• Functionality in a single unit

• Uses fewer components

• Long service life helps minimize environmental impact.

*Applicable for variable speed models.

Oil Filter

• Non-metallic, environmentally friendly and recyclable oil filter

• Aluminium housing

• Easy maintenance

• Compact design

Water Separator

• Compact, integrated, and unique design

• Separation performance is %99 even in very hot and humid conditions

• High energy efficiency with minimal pressure loss

Air Filter

• Two-stage filtration (Initial filtration/precision filtration)

• 99.9% efficiency in particle separation down to microns

• Low pressure loss (starting pressure fall<3mbar)

• Easy maintenance

• Long service life

Cooling System

• High cooling efficiency in compact air and oil heat exchangers

• Suitable design for operating up to 45°C

• Radial fan for high cooling efficiency (37 kW and above)

• Low noise level with low speed radial fans

• Cooling fan driver for maximum energy efficiency

Controller

In Fixed Speed Models;

• Without the need for an external main controller, ability to work synchronized for up to 5 compressors

• Weekly scheduler for starting / stopping the machine at 3 different time intervals can be individually set for each day of the week

• Internal ModBus communication

• User-friendly on-screen interface

• Alarm log records the last 20 alarms

• Periodic maintenance warnings and log records

In Variable Speed Models;

• 7” LED Display

• Group operation of up to 4 compressors

• Possibility to choose Master/Slave compressor

• Fast communication with ModbusTCP

• Ability to connect to customer DCS system via ModbusTCP

• Compact construction with integrated driver and controller

• Weekly scheduler for starting/stopping the machine at 2 different time intervals can be individually set for each day of the week

• Dual PID feature can run simultaneous PID for temperature and pressure

• Pressure PID ensures energy-efficient operation by maintaining the pressure at the desired level

• Temperature PID controls the fan speed to maintain the screw block’s most efficient operating temperature

• All inverter and compressor control data are managed from a single point

• Ability to determine co-aging times of the system with selectable parameters

• Built-in phase sensor

• User-friendly on-screen interface
