The powder-coated steel frame and housing offer excellent protection against harsh working environments, while the integrated water tank, water filter, and limescale protection system help safeguard critical components and extend machine lifespan.

Advanced Safety and Monitoring Systems

To ensure maximum operational reliability, the machine features comprehensive electronic monitoring systems, including:

• Leak detection and automatic shutdown
• Phase failure protection
• Overvoltage and undervoltage monitoring
• Flame and exhaust temperature monitoring
• Water shortage protection
• Overpressure protection
• Integrated limescale monitoring system

These intelligent safety features help protect both operators and equipment while minimising downtime.
