The BioPro™ 380 will produce twice the output of the BioPro 190, and can do so in 48, 23 or 13 hours, depending on your equipment decisions. The BioPro™ 380 delivers scale and flexibility. This machine allows you to produce 300 to 400 gallons a week at the traditional speed, or as much as 1200 gallons at highest output. At 1200 gallons per week, a business could save approximately $3156 per week. The BioPro™ 380 operates just like the 190; press the big green START button and walk away. What chemicals are required?
