¨ At lower relief valve settings, weights and capacities are higher (See Table)
Peaks of up to 4 X continuous flow rates can be sustained for 5 minutes if the vaporizer coils allowed to thaw in between.
¬ Height may vary on caster base models depending on specified wheel diameter.
Dura-Cyl has square caster base & Dura-Cyl MCR has round caster base.
