125-430 HP 100-125-150-175 psi 171-2.242 cfm

Oil Injected, Two-Stage, Direct Coupled, 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

• 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
