MVTA and MTA Flanged Sealed Process Heaters

Airtorch™ System Introduction

Convective Heating is One of the Most Versatile Ways of Delivering Heat!

MVTA Models

For Sealed Gas or Air with Blowers for Air/Gas inlet.

Temperatures up to 925°C.  

May may be used as a hydrogen heater only for non-combustible mixtures.

MVTA's are supplied with optional low-flow detection safety controls.

Temperature measurements are reported at the integrated thermocouple location supplied with the MVTA. Should you require to heat combustible gases for abatement purposes such as for semiconductor gas abatement then please contact us for custom solutions.

  • MVTA - Maximum pressure rating of chamber is ~ 14.5 psi in the standard models.  Temperature up to 925°C in MVTA925 models and 1000°C in MVTA models. These are sealed process gas heater with fan or blower capability.
  • GTA or GVTA - For high pressure vessel Airtorch use.  Custom engineering.  Please contact MHI directly.
  • Data Acquisition and Electronic Controls are available.

Some Of Our Many Satisfied Customers Using our Airtorch Products.  Small to large kW.

R.S. , OH
"We purchased the 10kW Airtorch™ to perform rapid cycling tests to qualify our product for a new customer. We have secured the contract and the Airtorch™ is still going strong for 2 years. We are now using it for new development projects."

J.M. of Morgan Tool
"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."

E.L. of National Lab, USA
"I really like the LTA ... very much. They are incredible! As per my calculation, we are seeing (very high) efficiency..."

Jim V. , Michigan
"This device will save us money."

Specifications subject to change at the time of quotation.

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.
