#PROP_VALUE#
The GST MP30M-LF is a compact, fully integrated mobile liquid-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-LF process, the system supports kerosene-based fuel configurations. 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 MP30M-LF 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.

Closed-loop
Mass flow control of process gases
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.
Integrated
Liquid-fuel supply and control system
Liquid Fuel Supply Module
The liquid-fuel module provides controlled delivery of kerosene to the HVOF torch according to the selected system configuration. Fuel supply is coordinated with oxygen flow, ignition, safety logic, and process recipes through the central control system.
High-pressure
Cooling-water circulation with continuous monitoring
High-Pressure Cooling-Water System
HVOF-LF torches operate under high thermal load and require continuous forced cooling. The MP30M-LF incorporates a high-pressure cooling-water circuit with continuous monitoring of the operating conditions required for reliable torch performance.
Oxygen (O₂)
Oxidizer
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, liquid-fuel lines, ignition circuit, cooling-water connections, and auxiliary process interfaces required for stable HVOF-LF operation.
I/O interfaces
Robot integration through communication and I/O interfaces
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.
Rotating-disk
Precision rotating-disk dosing system
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.

Applications
The MP30M-LF is intended for HVOF-LF 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 MP30M-LF 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.
