Description
LTA750-02 Airtorch® Hot Air/Gas Generator
Overview
The LTA750-02 Airtorch® is a compact cartridge-style hot air and gas generator designed to provide continuous high-temperature heating for industrial and laboratory processes. Operating at approximately atmospheric pressure, this unit delivers outlet temperatures up to 900°C while maintaining precise thermal performance for air and compatible non-reactive gases.
The LTA series features an integrated Type K thermocouple, compact design, and flexible voltage options, making it suitable for a wide range of process heating applications.
Important Safety Notice:
The stainless-steel body of the LTA750-02 will become extremely hot during operation above 700°C. Users are responsible for wearing appropriate personal protective equipment (PPE), including thermal gloves, eye protection, and other required safety equipment.

Temperature Performance
Operating Temperature Range
- Outlet temperature range: 100°C to 900°C
- Typical continuous operating temperature: 850°C
- Maximum recommended continuous temperature: 900°C
Temperature and Flow Performance
| Airflow Rate | Outlet Temperature | Inlet Air Temperature |
|---|---|---|
| ~3.6 SCFM | Up to 900°C | ~40°C |
| ~5.0 SCFM | Up to 750°C | ~40°C |
For systems operating above 750°C, accurate airflow control becomes increasingly important. For applications above 850°C, MHI strongly recommends the use of:
- A high-accuracy flow meter
- BPAN-O-PLUS control panel
- Closed-loop temperature feedback control
Power Specifications
Model
LTA750-02
Power by Supply Voltage
| Supply Voltage | Approximate Power Output |
|---|---|
| 208V / 220V | ~1.75 kW |
| 230V / 240V | ~2.0 kW |
| 277V | ~2.5 kW |
Typical Temperature Performance by Voltage
- 208V to 230V: Typical maximum outlet temperature approximately 850°C
- 240V: Up to 900°C under appropriate flow conditions
Proper airflow must be matched to the available power input to achieve the desired outlet temperature.
Gas and Air Requirements
Compatible Media
The LTA750-02 is suitable for:
- Compressed air
- Non-reactive gases
- Compatible process gases
Inlet Conditions
- Maximum inlet gas temperature: 75°C
- Typical inlet temperature for rated performance: 40°C
- Steady flow conditions are required for proper operation
Connections
Air/Gas Inlet
- 1/4″ NPTF compressed air fitting
Temperature Monitoring
- Integrated Type K thermocouple for process temperature monitoring
Control Recommendations
BPAN-O-PLUS Controller
For applications operating above 750°C, MHI highly recommends the use of a BPAN-O-PLUS controller.
Benefits include:
- Temperature feedback control
- Accurate power regulation
- Improved process stability
- Enhanced protection against overheating
For operation above 850°C, the use of both a BPAN-O-PLUS controller and a highly accurate flow meter is strongly recommended.
One control panel is required per heater unit.
Installation Requirements
- Designed for operation at approximately one atmosphere pressure
- Steady airflow must be maintained during operation
- Airflow and power input should be properly matched to achieve desired temperatures
- Suitable mounting and thermal protection measures should be provided by the user
Safety Information
Hot Surface Warning
The stainless-steel body of the LTA750-02 can reach elevated surface temperatures during operation.
When operating above 700°C:
- The heater body may become hot to the touch
- Thermal gloves should be worn
- Appropriate eye protection should be used
- Additional PPE and guarding should be considered based on the application
Operating Limits
- Maximum inlet gas temperature: 75°C
- Atmospheric pressure operation only
- Stable, uninterrupted airflow required
- Proper flow control is essential for high-temperature operation
Additional Notes
- Product images may be for illustration purposes only and may not exactly represent the delivered configuration.
- Performance values are based on typical operating conditions and may vary depending on voltage, airflow, gas type, and installation requirements.
Summary
The LTA750-02 Airtorch® Hot Air/Gas Generator delivers reliable high-temperature process heating in a compact cartridge-style design. Capable of continuous operation up to 900°C, it features an integrated thermocouple, flexible voltage options, and compatibility with air and non-reactive gases. For maximum performance and temperature stability, applications above 750°C should incorporate accurate flow measurement and BPAN-O-PLUS temperature control.
Unit Features:
- Steel Shell Construction
- Built-in Type K Thermocouple
- Lightweight, compact, ergonomic design
- 208, 220, 230 or 240V plug-in design
- Rapid heat-up
Such hot air guns are used in plastic welding, heat shrinking of thermoplastics, ceramic drying, on-site heat treatment, plastic forming, and many other applications.
The unique steel shell construction provides efficient heat recovery and management, providing high-efficiency hi-temperature discharge.
This recuperating design eliminates radiant heat loss while enhancing efficiency and maintains a cooler outer shell temperature.
Note: Parts of the surface are hotter than 50°C (DO NOT TOUCH), providing greater operational safety.
