saved per year

Replacing a diesel generator costing an average of $0.33 / kWh.

500t of CO2

saved per year

Replacing a diesel generator releasing 1 ton of CO2 per MWh.

Select number of valves:

5 valves

Bearstream turbine

Energy recovering turbine

Each pressure release valve dissipates an average 15kW of constant energy. A micro turbine can recover that lost energy at low cost, while reducing downtimes.

Typical pressure limit: 50-100 psi
Typical pipe diameter: 4-8 in
At 100 psi pressure flow: 5-50 l/sec
Dissipated energy: 15 kW / valve
