#PROP_VALUE#
The GST MP 30M-HV is a compact, fully integrated mobile gas-fuel HVOF system developed for high-performance protective coating applications in industrial workshops and field-service environments. The platform combines process control, oxygen and fuel management, high-pressure cooling, powder feeding, electrical control, and system monitoring within a single mobile industrial enclosure.
Designed around the HVOF-GF process, the system supports hydrogen-based fuel configuration. Its closed-loop control architecture provides stable management of critical process parameters while the touchscreen HMI, remote diagnostics, process-data recording, and configurable user access support repeatable production and efficient service.
The MP 30M-HV can operate as a compact mobile coating workstation or serve as the process core of a larger automated cell. Communication and I/O interfaces allow integration with industrial robots, workpiece positioners, soundproof spray booths, exhaust and filtration units, and other project-specific peripheral equipment.

System configuration
The MP 30M-HV is built as a compact mobile HVOF-GF process platform. The current product configuration integrates the principal process, fuel, powder, and control functions inside one mobile industrial cabinet, while robots, positioners, spray booths, and filtration equipment can be added according to the production task.
Monoblock
Mobile monoblock architecture
Process Cabinet
The process cabinet integrates the main HVOF-GF functional modules into a single mobile enclosure. The architecture reduces installation complexity and allows the equipment to be deployed in workshops or field environments while maintaining industrial-grade process control and service access.

Control software
Process Control & Software
The MP 30M-HV uses a PLC-based control architecture developed for stable HVOF-GF operation, process transparency, and traceability. Critical parameters are monitored continuously and displayed through the operator HMI. Approved operating ranges for each configured torch can be stored in the control system to reduce the risk of operation outside validated conditions.
- Closed-loop management of critical HVOF-GF process parameters.
- Graphical touchscreen HMI for operation, recipe selection, and monitoring.
- Real-time visualization of system status and process values.
- Process-data acquisition, reporting, and complete recording for traceability.
- Multi-level password-protected user access.
- Remote diagnostics and technical-service access.
- Communication and I/O interfaces for robots and external process equipment.
- Expandable software architecture for additional approved HVOF torches and auxiliary systems.

Gas Supply and Regulation Module
The gas module supplies, regulates, and monitors the process gases required for HVOF operation. Accurate gas control directly influences combustion stability, flame velocity, particle acceleration, coating density, and process repeatability. Closed-loop mass-flow regulation is used to maintain consistent operating conditions.
Forced-water
Cooling with dedicated refrigeration unit
High-Pressure Cooling-Water System
HVOF-GF torches operate under high thermal load and require continuous forced cooling. The MP 30M-HV incorporates a high-pressure cooling-water circuit with continuous monitoring of the operating conditions required for reliable torch performance.
High-pressure
Oxygen circuit, gas-fuel lines and ignition
Control and Distribution Module
This module provides the process interface between the mobile cabinet and the HVOF torch. It manages the high-pressure oxygen circuit, gas-fuel lines, ignition circuit, cooling-water connections, and auxiliary process interfaces required for stable HVOF-GF operation.
PLC-based
Closed-loop process control
Electrical Control Module
The electrical module contains the PLC-based hardware and software used to coordinate the complete system. Closed-loop control algorithms supervise critical process variables, while communication and I/O interfaces provide connectivity to industrial robots, filtration systems, workpiece manipulators, and other external equipment.

Hopper volume
Powder Feeding System
The powder feeder uses a precision rotating-disk dosing mechanism for stable and adjustable powder delivery. Powder is transferred into the carrier-gas stream and delivered to the HVOF torch. Carrier-gas flow is regulated by a mass flow controller, while hopper weight is monitored by a strain-gauge load sensor and displayed in real time on the HMI.

- Soundproof spray booth
- Exhaust and filtration unit
- Additional process monitoring and quality-control equipment
Compatible HVOF Spray Guns
The MP 30M-HV control architecture supports approved HVOF-GF torch configurations with predefined operating limits and validated process ranges stored in the control system. Additional HVOF-GF torch configurations can be integrated on a project-specific basis after technical confirmation by GST.
The MP 30M-HV HVOF-GF configuration is built around a gas-fueled HVOF gun package. The current GST DJ2600 is the best compatible HVOF-GF gun for the MP 30M-HV HVOF-GF mobile spray platform.
Applications
The MP 30M-HV is intended for HVOF-GF applications where dense, wear-resistant and corrosion-resistant protective coatings are required together with flexible equipment deployment. Final suitability depends on the coating specification, feedstock, substrate, component geometry, and approved process parameters.
Aerospace
Liquid-fuel HVOF can be used for high-performance carbide and metallic coatings on landing-gear components, turbine-related parts, and other wear-critical aerospace hardware where coating density and repeatability are important.
Power Generation
Typical applications include protective coatings for turbine seals, wear rings, boiler-related components, and other parts subject to erosion, wear, or demanding thermal-mechanical service conditions.
Industrial Repair & Field Service
The mobile architecture is particularly relevant for repair and maintenance work where the HVOF process equipment must be deployed close to the component or moved between workshop areas. Appropriate spray containment, ventilation, filtration, and safety measures remain required.
Automated Production Cells
The MP 30M-HV can also be integrated as the process core of a robotic HVOF cell, combining the mobile process cabinet with an industrial robot, workpiece positioner, soundproof booth, exhaust filtration, and additional monitoring equipment.
FAQ
What is the MP 30M-HV?
The GST MP 30M-HV is a compact mobile HVOF spray system engineered for high-quality thermal spray coating applications outside a fixed production cell. The system integrates process-gas control, powder feeding, safety functions and HVOF gun operation into a transportable platform, making it suitable for on-site coating, repair and maintenance of large or difficult-to-move components.
Which fuels can the MP 30M-HV use?
MP 30M-HVOF-LF — liquid fuel, typically kerosene or ethanol,
MP 30M-HVOF-GF — gas fuel, if you offer a separate gas-fueled mobile based on hydrogen configuration,
MP 30M-HVOF-E — ethanol-fueled version.
Which HVOF torch is confirmed for the system?
The current configuration identifies the GST DJ2600 for hydrogen-fueled operation. Additional HVOF-GF torches may be integrated on a project-specific basis after technical confirmation.
Why does the mobile HVOF-GF system include a fuel-gas leak detector?
Because the GST mobile HVOF-GF system uses combustible fuel gas, the leak detector is included as an independent safety layer.
In a mobile system this is especially important because the equipment may be operated in different workshops, temporary coating areas, or enclosed spaces where ventilation conditions can vary. A leak can occur at regulators, valves, hoses, fittings, the gas-control module, or the spray gun connections.
What powder-feeding principle is used?
The current product description specifies a precision rotating-disk dosing mechanism with mass-flow-controlled carrier gas and hopper-weight monitoring by a strain-gauge load sensor.
How many powder feed lines does the mobile HVOF-GF support?
Powder feed lines: 1 standard; additional line optional/project-specific.
