If the flow rate is of the order of 2-40 scfm please choose from the MTA, VTA or LTA models or the MVTA925 flanged units. If the flow requirement is higher than 40scfm please choose from MVTA models. Airtorch units are supplied with several safety features like the over temperature cut-off feature and the low flow cut-off feature (model dependent).

VTA 600-900C Models

VTA750-4GS, VTA-1GC,


VTA Airtorch models are process air heaters designed for use with fan/blower (maximum back-pressure of 50 w.c./inches of H20 ~ 1.8 psi.).

 1kW VTA

VTA-1GC with fan– 120V

Flow Temperature Curves / Airtorch Application Information Page

  • Airtorch Operation:  The flow rate and temperature are related. The air/gas heater should not be used beyond its rated temperature or power. The thermocouple is integral to the heater. The principle of an air/gas heater is for flowing gas to heat within the residence time of heater/configuration.
  • Flow Rate is Important: If using a blower or fan the air flow will be controlled by the characteritics of the fan or blower. 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 fans output large CFM.. Blowers are considered in circumstances where larger pressure drops are present.
  • For LTA and MTA when the inlet flow is pressure driven, the flow rate is often set by an appropriate SCFM flow meter. Minimum flow rate rated for the should be maintained when powered. MHI power controllers cmay be used to set the power.

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

Most units are compatible with an optional control panel. Contact us or call us at 513-772-0404. VTA-BL models have integrated air/gas controls. VTA models offer low flow cut-off with extendable user interface. Fan control is available with the FANCS, which also includes a temperature controller.
