Technology and Applications

Please contact MHI for Flow Rate vs. Temperature Charts. MHI units operate close to 100% power transfer efficieny. Models can accomoadate almost all line voltages with a factory setting.

LTA
850-900°C max- temperature.
use with compressed air or gas

For higher temperature use, VTA's, MTA925 or AT models.

VTA
750-900°C max- temperature.
VTA's use integral fans and/or blowers. Energy Saver. VTA's allow for full power transfer up to 900C. Beyond 900C use AT models.

MVTA
750-925 °C max- temperature.
MVTA's use integral fans and/or blowers and are fully sealed. Energy Saver. MVTA's allow foralmost full power transfer up to 900C.

AT models

Very High Temperature Systems.

Beyond 900C use AT models or plasma models.

When should I use a compressor and when should I consider a blower based system for my air or gas flow? If in doubt please contact MHI.

** : FANCS: Fan speed controller and temperature indicator

* Check for airflow that must be maintained when energized at the maximum rated power.

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

LTA MODELS

(for use with compressed air and power controller)

LTA Models allow for easy idependent power and flow control seperately. See column below for minimum air setting for maximum temperature at lower power setting. Or use at full power setting (contact MHI for flow detals)

48kW and higher available. Please call MHI. Also see MTA925 page. Note that dimensions are to be read within a standard tolerance. Please call MHI.

* This is also minimum airflow required when energized. (Please contact MHI)
** TI: Temperature indicator

For LTA's please note above BPAN and RPAN's provide full PID control of temperatures.
TI is not a power controller but only a temperature read -out.

FOR VTA's fan control is available with the FANCS which also has the temperature controller Please inquire about our blowe based solutions for small and large VTA installations.
For a picture of the FANCS Unit please see pictures below.
