COAIRE OIL INJECTED ROTARY SCREW
NEW GENERATION AIREND DEVELOPED BY COAIRE
Coaire’s latest version of the Alpha rotor screw compressors were developed in conjunction with Svenksa Rotor Maskiner (SRM), a Swedish rotary compressor designer and manufacturer.
This new design is owned by Coaire for exclusive use. The improved airend as much as doubles life expectancy through lower vibration and reduces sound levels compared to previous models.
FIFTH GENERATION ALPHA PROFILE PROMOTES SMOOTH AND RELIABLE PERFORMANCE
Reduced blow hole design eliminates friction between rotors, thus reducing vibration and noise levels while minimizing power loss.
- State-of-the-art machining, casting, measuring, grinding, and testing process ensures a high quality product.
- Improved precision of the rotors by adjusting tooling pressure angle and narrowing the sealing line, while reducing the resistance and space efficiency at the same time.
- The thermal efficiency of the Alpha profile is 9% higher than a conventional airend profile.
MADE WITH STRONG AND DURABLE MATERIALS
- All airends are cast from high quality material produced with innovative technology, equipment, and tooling.
- Refined cabinet structure consists of heavy gauge metal (and sound absorbing material) with service-friendly access panels allowing for very low sound levels and easy access for service and adjustments.
- G2.5 grade balance control guarantees low vibration and extended life expectancy of the bearings.
- Dual bearing structure provides rigidity for the axial load.
- High efficiency 3-stage oil seal system for improved leak prevention
MULTI-FUNCTION, USER -FRIENDLY CONTROLLER
- Easy operation key-pad
- Multilingual (6 languages, including English, Spanish, Portuguese, Korean, Russian, and Chinese)
- Pyramid structure menu designed for convenient use
- Large LCD panel
- Up to 60 journal entries are saved to secure stable operation and thorough protection for your machine.
- This user-friendly controller is included.
EASY MAINTENANCE
- Easily detached service doors allow convenient replacement of all parts and minimize maintenance time.
- Flanged connections use a high quality o-ring design which reduces maintenance costs.
- Large oil drain and oil input ports reduce oil change times.
- Two visual oil level sight glasses for positive oil level checks
DIRECT DRIVEN SYSTEM
- All 30hp – 200hp airends are connected to the motor by a direct or gear driven system.
- A direct driven system increases transfer efficiency.
- Coaire uses only high-efficiency certified motors.
VARIABLE SPEED DRIVE (VSD) TYPE
Available as an option:
Inverter Bypass System
This option allows air compressor operation when the inverter is offline.
➊ Inverter & Control Box w/Line Reactors
➋ Visual Oil Level Gauges
➌ Separator Tank
➍ Airend
➎ Suction Filter Assembly
➏ Oil & After Cooler
VSD Screw Compressor Energy Savings
- Reduced power consumption during no-load operation: quick change rotation speed allows quick and accurate adjustment to the system air requirements fluctuations
- Required compressed air = produced compressed air
- Reduced unnecessary production of compressed air while minimizing energy loss
- Pressure control allows pressure configuration based on the system’s requirements
- Soft start prevents power loss from over-amperage and extends motor life.
- Inverters are CE and UL certified.
VSD Screw Compressor Applications
- Systems with large fluctuations in compressed air demand benefit when:
- production line consumption varies
- day and night shift air consumption vary
- monthly and seasonal air consumption vary
- Production lines with future expansion plans
VARIABLE SPEED DRIVE
TOUCH SCREEN CONTROLLER
- 10″ touch screen
- Easy to monitor operating status
- Data back up saves file in Excel format
- Easy setup configuration, operation mode, and controls
- Trend analysis of compressed air usage is available using graphs (daily, weekly, monthly)
- Operating scheduling
- This touch screen controller is available as an option.
