 GVTA or GTA with Blinded Flange Shown Above

GTA / GVTA are ideal for demanding high-pressure applications such as:

  • high pressure engine sensors and exhaust
  • jet engine test stands
  • reactors (industrial preheating)
  • combustion systems
  • simulation testers
  • MVTA, GVTA and GTA are often used for combustion (simulation)
  • more applications…..Smartpower™ device

Low maintenance devices. These units are easy to service.

MHI provides very important warranties which cover all parts even heaters. Attractive service contracts are offered where required.

All GVTA models discussed on this page are examples only. Exact specifications are quoted as per customer requirements. Temperatures are rated at standard t/c locations. However, typically users have indicated very little temperature drop within extended piping. GVTA models accept high pressure inlets.

Pressure drop: Very Low. MHI offers DirectFlow™ Airtorch models. MHI uses its combined thermal knowledge across diverse equipmet offerings to optimize and provide low friction flows.

Custom units upto 250kW have been designed. Choice of Temperatures. Choice of inlet three-phase voltages 208, 220, 240, 380, 440, 480 or 600V. Please discuss with MHI.

 

* Normal Flanged (GVTA) for 4-28″ diameter pipe (GVTA) or blind (subject to actual quoted specifications) ** Normal flanged for 3-8-28″ diameter pipe or blind (subject to actual quoted specifications).  In-line VTA high pressure models have in-line flanges as per code.

New recommended models for combustible gases  Models CGH-KW-(XPV)-(YPV).

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 1.8psig).   This condition remains true even when the fan can output large CFM flows. Blowers are considered in circumstances where larger pressure drops are present.
