Steam Beds

The steam traps are often located at one end for ease of maintenance, with long pipes connecting them to the drainage points. If steam-locking is a problem in these long pipes, then a Float / Thermostatic steam trap with a steam-lock release is the best selection. The beds should be air vented at points remote from the steam entry. Steam supply lines to ironers should be drained, ideally using a separator.
