Description
Custom MHI MTA925 Airtorch Air Heater
MHI MTA Process Air/Gas Heater (2kW) (A bundled price of optional BPAN or BPAN-O-PLUS is offered with this product- Please contact MHI 513-772-0404 if required).
When selecting flow meter please indicate Air or Nitrogen in the remarks column.
- Continuous Hot Air Discharge up to 925°C (Nominal)
- Temperature Control is by flow control. (accuracy provided by optional BPAN-O-PLUS Control Panel)
- 2 kW Total Power (Nominal will be slightly different for 208V and 240V)
- Stainless Steel Shell Construction
- Built-In “K” Type Process Thermocouple
- 208/240V Plug-In Design
- Ready to Use. 1 Bar. For high pressure units please contact MHI for a paper quotation.
- Minimum Flow 5.0 – 5.5 SCFM for Air (different for other gases)
- Threaded exit nozzle 1/2″ NPT Male
- Full Power and Flow Controller Options Available (call MHI)
- BPAN-O-PLUS models have a temperature and over-temperature control, Canada rating choose model with cUL. (call MHI)
- For MTA/MVTA models when the inlet flow is pressure driven, the flow rate is often pre-set by an appropriate SCFM flow meter.
- Minimum flow rate should be maintained. MHI BPAN-O-PLUS power controllers (optional) can be used to set power.
- Please use calibrated Flow Meters.
Model: MHI Model# MTA925-02
Temperature: 925°C Maximum Continuous (Minimum airflow to be maintained). Temperature measured by internal TC before nozzle exit. Exit temperatures highly dependent on application and use conditions.
Thermocouple: Built-in K-type thermocouple. Can be linked for external display (TC-READ) or full POWER control (BPAN-O-PLUS Control Panel).
Element Installation: Factory installed. Heating elements can only be serviced at MHI approved location, where applicable. Please contact your MHI sales representative for service program and details.
Wiring Requirements: 240 Volt, single phase @ 50/60Hz, 9 Amp Max current. Unit may be used for 220V input.
Power Consumption: 2 kW (Nominal @ 240V). Slightly lower power and temperature for 220Volts.
Frequency: 50/60 HZ
Air Source: Via compressed air source or compressed gas source (e.g. Nitrogen / Argon). Approximately 5 SCFM is the minimum airflow (compressed air) required when operating the device at full power to achieve maximum temperatures. Compressed air source not included and is within the user’s scope. Please contact MHI for assistance.
Inlet: 1/4″ NPT Male
Outlet: 1/2” NPT Male
Display: Not included. Built-in thermocouple can be linked for external display on TCREAD basic display. Optional: 3 ½ LCD display switchable between °C and °F
Power Control: Optional: MHI BPAN-O-PLUS™ Control Panel. Single Phase Controller. Includes on-off switch, thermocouple readout and PID controller. Advanced phase angle fired SCR with soft start and current limiting features integrated for device protection and control.
Flow Control: Optional: FLM flow meter for basic flow control of pressure flow. Setting range suitable for 2kW. Please indicate Air or Nitrogen in the remarks column. SCFM readings.
**Fans are employed when the drop in pressure of the system is no greater than approximately 50 in. w.c. This condition remains true even when the fan can output large CFM values. Blowers are considered in circumstances where larger pressure drops are present.
Controls: Can I use my own. Generally not an issue if you have experience. Please ensure that you have over temperature cut off and soft start features like the BPAN-O-PLUS offers. This is particularly important when using close to the maximum rated temperatures. Please note that sealed units cannot be repaired if a burn out occurs. There is no warranty on the heaters when used with non-MHI controls or if control features are disabled.
Efficiency. Flow chart to consider https://mhi-inc.com/airtorch-design-graphs/. It is a general guidance chart not specific to your device. Also there could be small variations of the nominal resistance or air flow provided by flow meters (even mass flow meters).

“Using the LTA as the primary heat source for my customer’s tool turned out to be a wise decision. It’s robust for continuous use in a shop floor environment.”
C.A., UK (International)
I am very satisfied with the Airtorch™; we operate it everyday between 1100 and 1200°C for our experiments.
EL, National Lab, USA
“I really like the LTA … very much. They are incredible! As per my calculation, we are seeing (very high) efficiency…”
Nate M, Utah
“We added the 15kw Airtorch to our existing Gas Tunnel Kiln to improve uniformity and overall drying time. It was cheaper than buying a new kiln”
Paul F, Pennsylvania
“We’ve used the Airtorch™ as a pre-heater for our application. It works well, we bought two…”
Ron J, Ohio
Finally, a product for die heating that really meets our needs!”
Tim D, Ohio
“Airtorch™ is a great concept, it works well for my unique applications…”
Ken F, Tennessee
“This hot air device offers great versatility, its the device I’ve been waiting for…”
Jim V, Michigan
“This device will save us money.”
