General Features
• IE4 efficiency-class electric motors
• Two-stage screw block
• Variable and fixed speed motor power options
• Water cooling and heat recovery (optional)
• Operating with low noise level

Screw Block
• Two-stage screw produces energy efficiency by up to 10%
• Higher flow rate by up to 10% comparing to single stage
• Direct coupled
• Reduced internal losses
• Thanks to low compression rate, low axial and compression forces
• Thanks to low rotor speeds, a long service life
• With two-stage compression near isothermal compression
• Reduced axial and compression forces resulting in longer screw and bearing service life
Electric Motor
• IE4 efficiency-class electric motors
• Motors have B-class temperature increase
• Continuous operating feature
Oil Filter
• Eco-friendly and recyclable oil filter
• Oil filter contains no metal alloys
• Aluminium housing
• Easy maintenance
Water Separator
• Compact, integrated, and unique design
• Reliable initial separation (>% 99)
• High separation efficiency at high humidity and temperature
• Zero loss drain
• High energy efficiency with minimal pressure loss


Air Filter
• Protects the screw block by separating particles down to 3 microns
• Intake pressure loss: <2 mbar results in high efficiency throughout the maintenance period
• 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
• Low noise level with low speed radial fans
• Energy efficiency with optimum oil temperature thanks to VSD-controlled radial

Controller
• 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
• Dual PID feature on inverter-equipped models can run simultaneous PID for temperature and pressure
• Pressure PID on inverter-equipped models ensures energy-efficient operation by maintaining the pressure at the required level
• Temperature PID on inverter-equipped models controls the fan speed to maintain the screw block’s most efficient operating temperature
• On inverter-equipped models, all inverter and compressor control data are managed from a single point
• Internal ModBus communication
• User-friendly on-screen interface
• Alarm log records the last 20 alarms
• Periodic maintenance warnings and log records
