ACOMASS® Jet Control Valve

The newly developed VACOMASS® jet control valve is unique world-wide and combines aerodynamically challenges with high-level manufacturing. The special design is registered for patent approval worldwide and has been successful for many years in small and big wastewater treatment plants. 

• Stainless-steel control valve with a central control axis and electrical device drive for precise control of air supply into aeration tanks
• Linear working characteristics from 5%-95%
• Closes gas-tight
• Minimal pressure drop due to high pressure recovery on Venturi-Outlet
• Reduction and expansion of piping is no necessary 
• Air flow meter can be integrated or placed directly in front of the jet control valve (straight inlet and outlet pipe not necessary)

Functions of VACOMASS® Jet Control Valve
1) Controlling the infeed of oxygen into a tank
2) Distributing aeration air over individual tanks or aeration zones as required in interconnected systems

Other features of VACOMASS® Jet Control Valve
1) Suitable for gas temperature from -40°C to 150°C
2) Aerodynamic design 
a. Reduces vortices formation, low pressure drop and noise
b. High level of pressure recovery, decreases energy consumption
3) Out-flow from valve has regular profile, allows first drop pipes to aeration tanks be connected after valve
4) Low drive torque is needed due to low flow resistance, operation costs saved
5) Weight of valve is low, allowing easy installation and minimal additional fixations 

VACOMASS® Flow Meters


The VACOMASS® Flow Meters are for measuring the flow rate of aeration air in wastewater treatment plants up to 220°C. 

Features of VACOMASS® Flow Meters

1) Thermal dispersion air mass flow meter

2) Direct measurement of normal volumetric or gas mass flow in dry gases at standard conditions

3) Flow measurements unaffected by pressure and temperature fluctuations 

4) Stainless-steel sensor with no moving parts

5) Compact and rugged design for good reliability, maintenance-free, corrosion-proof 

6) Easy installation and servicing

7) Dynamic response ideal for monitoring, totalisation and control

8) 10-digit LED display to indicate actual flowrate or totalised flow





Different Models of VACOMASS® Flow Meters

1) VACOMASS® flow meter SS

        a. Electronics are located in a compact, pressure-rated stainless-steel body with a sealed connector box. 10-digit LED integrated display is an
       option

2) VACOMASS® flow meter AL

        a. Electronics are located in a compact aluminium body. 10-digit LED integrated display is an option

3) VACOMASS® flow meter AL DIN

        a. Electronics are located in a compact aluminium body

4) VACOMASS® flow meter AL 100
