รายละเอียด
The advantages to this type of application can be summarized as:
- Zero contaminant emissions
- Ability to work both outside and inside the Hangar
- Practically no noise input
- Savings on the machine operating cost
- Savings on maintenance (given the absence of the diesel engine)
- Reduction in defects and increased profit for the system life (no rotating parts)
Static GPU:
- Model ST400-MICRO-4,5
- Model ST28-MICRO-600
- Model ST400/28CTL-25
- Model ST400-BS120
