Any closed system or tank can be overfilled and doing so can prove to be dangerous or can rupture your tank and ruin your equipment at the least.
Both the Extractor Tank and Recovery Tank can be filled up to the shoulder of the tank. The shoulder of the tank is the max fill line when filling with solvent. The area above the shoulder of the tank is the air buffer zone. This area should never be filled with liquid.
TE175 system can hold 700 ml or 400 grams of pure butane solvent.
TE700 system can hold 2800 ml or 1600 grams of pure butane solvent.
If mixing butane with other solvents you will need to know what a milliliter of that solvent weighs to properly calculate the exact volume that solvent will take up in the tanks. Then adjust accordingly.
If you use water for example, 1 gram of water occupys 1 milliliter of space. Meaning a gram of water will take up more space than butane because 1 milliliter of butane only weighs .577 grams. If you fill up with 400 grams of pure water you will only have 400 milliliters of water. Way under 700 and very safe.
To over fill when mixing butane with other sovlents you would really have to miscalculate.
