Using dryer in 220V country
There are two systems in use in the states
110v dryers are available that fit a standard 11v 15a socket
110/220v fit the oversize 'dryer' sockets, and they are two 110v phases 90 degreees apart
the motor runs of a single phase 110v.
there is 220v between the 'outside', the active lines of the two phases, at any time, but it is not useable to provide mechanical power as a single service, due to the complicated shape of the wave form when you add out of phase voltages together, but is ok to drive the heaters, they have no mechanical efficiency requirement
A 2 phase 110v heater it means 3kw can be supplied without a 30 amp circuit
but it becomes difficult to use a single phase 220-240v transformer to provide 2x110v 90degree 2 phase current unless you specially buy one in. .
High power applications in 220-240v are generally supplied by 415v 3 phase 60deg supplies,
Any transformer would be onsellable at the end of your posting, to your replacement, who would doubtless be in the same boat as you, with a heap of 'stuff' that needs to run.
UK Aus NZ may be sources of transformers, or dryers to suit.
check with Australian UK NZ suppliers as well as local Indian ones, as those countries are also nominal 240v single phase home suplies and they may have (1) the dryer, or (2)the transformer to suit the 110 2 phase dryer
