This is a strange one as, in my experience, neonatal unit "room temperature" is almost always too hot for comfort, rather than too cold.
The other interesting factor is, rather than one type of ventilator and one type of circuit being mentioned, we have a situation where various combinations all suffer from similar problems.
OK ... are we talking about one particular station (position in the room) here? The one right next to the HVAC duct (or open window, doorway, whatever) for instance. Or is this a more general problem?
Of course, we could also be heading up the Garden Path with that one ... maybe all the vent/circuit combinations are not the "ones of choice" anyway. Lack of heating "power" has already been mentioned - due (I suspect) to poor impedance matching. So ... have other (heated, supposedly) circuits been tried (like the ones recommended by the vent manufacturers, for instance)?
