Attributes and benefits
![Coolers Coolers](https://ivysads.com/wp-content/uploads/2023/12/Coolers.jpg)
Coolers
- Cupronickel coolers with water-in-tube system and is designed for temperature difference of max. 14ºF
- Better Corrosion resistance and 28 times better thermal conductivity than stainless steel
![Rotor Rotor](https://ivysads.com/wp-content/uploads/2023/12/Rotor.jpg)
Rotor
- Patented eta-V profile with 3/5 lobe for high swept volume and lower pressure ratio
- Rotor operates at a lower speed due to the patented profile and fewer inter-lobe Leakages
- Rotor and housing are coated with PTFE-based food-grade PP coating to resist
- Corrosion and endure at high temperatures up to 482ºF. This results in optimum long-term performance with no loss of efficiency
![Capacity-Control-Valve Capacity control valve](https://ivysads.com/wp-content/uploads/2023/12/Capacity-Control-Valve.jpg)
Capacity Control Valve
- Hydraulic rack and pinion-type actuation
- Valve membrane made of stainless steel metal instead of elastomer
- More than one million cycles of life between rebuilds
- Simultaneous closing of inlet valve and opening of blow-off valve by rack and pinion to ensure safety and air-end life
- Less maintenance compared to electrically actuated valves
![Air-Seal Air Seal](https://ivysads.com/wp-content/uploads/2023/12/Air-Seal.jpg)
Air Seal
- Carbon-impregnated SS floating type seals
- Axially locked by Belleville spring and radially locked by compressed air
![Oil-Pump Oil Pump](https://ivysads.com/wp-content/uploads/2023/12/Oil-Pump.jpg)
Oil Pump
- Separate motor-powered oil pump ensures lubrication before and during start of the machine (ensuring no dry running of gears and bearings)
- All oil tubing is made of Stainless Steel to increase reliabilityrnrn
![Timing-Gears Timing Gears](https://ivysads.com/wp-content/uploads/2023/12/Timing-Gears.jpg)
Timing Gears
- Helical gears, precision ground to DIN 4 quality and case hardened to minimize transmission losses and noise during operation
- Dynamically balanced to reduce vibrations by optimizing the loads on bearings and increasing bearing lifern
