Over/Under Pressure Unit

System Accessories

To regulate biogas pressure within the digester and to comply with local regulations, an over/under pressure unit is required.  The unit that we offer from our German supplier is highly reliable and is well-insulated with internal frost protection to cope with our Canadian winters.  The units are constructed of high grade, 316 stainless steel, and contain a sight glass on the over and under pressure side of the unit for easy inspection. Lastly, the units can be ordered with pipe connections ranging from 6-12” and relief pressures are always adjustable.
