We just got a heat tunnel from one of our overseas plants. It is a 380v 3 phase machine, the controls and motors have a xformer to step down. My question is the heat elements are 380v 16kw x3, If I only supply 240v to them will I get a direct heat loss of approximately 1/3. The unit will heat to over 400F and I only need 240F so at 1/3 loss it should work I think. I am going to test it but was just curious what others say. I do have control of the air flow also.
