The BioPro 190 processes one 50-gallon (190-liter) batch every 48 hours, or every 23 hours with the BioPro 190EX. Each batch uses 50 gallons of feedstock oil.

Adding a SpringPro T76 dry-wash system can shorten the cycle to roughly 11.5 to 13 hours, since the raw fuel is purified in the T76 rather than through the 24-hour water wash and drying sequence.

A 50-gallon BioPro 190 batch uses:

• 10 gallons of methanol
• 1,520 grams (3.3 lbs) of NaOH (lye) or 2,350 grams (5.2 lbs) of KOH (caustic potash)
• 190 mL (0.8 cups) of sulfuric acid

Catalysts are also sold in pre-measured doses, which removes the need to weigh them for each batch.

Yes. The BioPro 190 runs on standard 115V AC power with a maximum draw of 15 amps, so it does not require a 230-volt circuit like the BioPro 380. A dedicated circuit is still advisable so other loads do not trip the breaker mid-batch.

Units built for 50 Hz power are available for customers outside the United States.

The BioPro 190 weighs 405 lbs empty and has a footprint of about 22 by 22 inches, roughly the size of a typical refrigerator. It is self-contained, with no separate settling or wash tanks.

Springboard Biodiesel recommends a working space of at least 10 by 8 feet with an 8-foot ceiling, leaving room to load ingredients, drain glycerin and connect the water supply.

The BioPro 190 uses about 38 gallons of fresh water per batch for its three-stage water wash: a spray wash, then two turbulent washes, followed by an evaporative drying cycle.

The wash and all other steps are PLC-controlled in automated mode, with switch-actuated manual overrides. Used wash water can go down the drain where local rules allow, or water washing can be avoided entirely with a SpringPro T76 dry-wash system.
