LTA Airtorches™ are process air heaters designed for compressed air/gas input. LTA models offer temperatures up to 850°C.

VTA Airtorches™ are process air heaters designed for or supplied with by a fan or blower. VTAs offer temperatures up to 900°C. Fans are employed when the drop in pressure of the system is no greater than approximately 50 in. w.c. (50 in. w.c./inches of H20 is approximately 1.8psi.) This condition remains true even when the fan can output large CFM values.  Blowers are considered in circumstances where larger pressure drops are present.

VTAs are highly energy efficient, allowing for less energy use and higher cost savings. VTA models are fully compatible with electronic control panels, allowing for accurate control of flow rates and temperatures for your process. Suggested uses for these models include integration into existing systems for cable conveyors, drying, process heating, coatings, production line heat treating and a number of other specific process applications.

VTA Models

Because of their versatility, MHI's Airtorches™ may be used in several applications. Because each application is unique, please contact us to discuss which product best fits your needs. VTAs offer full power transfer up to 900°C.

All Models listed above, unless noted otherwise are single phase systems.

VTAs include an integrated Type "K" thermocouple.

Most units are compatible with an optional control panel. Contact Us Online or Call Us at 513-772-0404.

VTA-BL models have integrated air/gas controls.

3-Phase VTAs require TRIPAN Control Panel.

Dimensions are subject to change and exclude flow controls.

VTA has low flow cut-off with extendable user interface. VTA also has full control features if required, please discuss with an MHI Representative.

Fan control is available with the FANCS, which also includes temperature controller.




LTA Models

LTA Models allow for easy idependent control of power and flow-rate. LTA Airtorches™ are to be used with compressed air and power controller.

*At full power the minimum flow required is higher. This is also minimum airflow required when fully energized to rated kW.

All LTA models feature an optional Temperature Indicator module.

 All LTA models feature an integrated Type K thermocouple.

Note that dimensions are to be read within a standard tolerance.

Contact Us for Flow Rate vs. Temperature Charts. MHI units feature a nearly 100% power transfer efficiency.
