GVTA and GTA MODELS (High Pressure) * Air, inert, and non-combustible gas ready * Shown below is the typical configuration for a 60kW- 400kW GVTA Note that the basic design follows the MVTA style or VTA style depending on temperature and pressure
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 minimal temperature drop within extended piping.
Pressure drop: Very Low. MHI offers DirectFlow™ Airtorch models. MHI uses its combined thermal knowledge across diverse equipment offerings to optimize and provide low friction flows.
Choice of Temperatures. Choice of inlet three-phase voltages 208, 220, 240, 380, 440, 480 or 600V. Choice of turn-down ratios. Please discuss with MHI.
* Normal Flanged (GVTA) for 4-36″ diameter pipe (GVTA) or blind (subject to actually quoted specifications) ** Normal flanged for 3-8-28″ diameter pipe or blind (subject to quoted specifications). In-line VTA high-pressure models have in-line flanges as per code.
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. If inlet pressure is one atmosphere, choose from VTA or MVTASelection Guide Airtorch™ (DPF, LTA, VTA, GTA, MVTA925, MVTA)
