Equilibar Introduces New LPR2
Ultra Low Pressure Regulator
- Controls down to 0.02 psig!
Equilibar introduces a new Ultra Low Pressure Regulator that controls down to 0.5 inH2O (0.02 psig)!
Designed for static and very low flow applications, the patent pending LPR-2 design extends
the control range well below other commercially available regulators.
Specifications:
| Outlet Range: |
0.5 - 7 inWC (0.02 - 0.25 psig) |
| Inlet Pressure: |
10 - 100 psig (regulated) |
| Ports: |
1/4" NPT inlet/outlet |
| Fluids: |
Air and inert gases |
| Major Materials: |
Cast zinc, PolyEthylene, Rubber |
Low Flow Test Results:
| Sensitivity |
+/- 0.02 inWC (0.0007 psi) |
| 7 Day Stablity |
+/- 0.06 inWC (0.002 psi) |
| Max Air Flow: |
1 SCFH
(4 inWC setting @ 0.7 inH2O droop)
see chart |
|
Air Consumption: |
<0.05 SCFH
|
|
Relieving Sensitivity: |
~ 8 inWC @ 1 SCFH
(2 inWC Setpoint) |
Low Flow / No Flow Applications
The LPR2 can be used as a stand-alone pressure source for applications requiring no flow or very low gas flow:
- Laboratory, research, scientific
- Pressure testing delicate membranes
Medium/High Flow Applications
Use in combination with Equilibar Precision Back Pressure Regulator
The driving force behind the development of the LPR2 is as a setpoint pressure source
for the Equilibar Precision Back Pressure Regulator. These back pressure regulators can
mirror the ultra low pressure from the LPR2 into much larger process streams, providing
pressure control capabilities never before experienced in chemical processes.
- Vessel inert gas control
- HVAC
- Extrusion and blow molding cavity pressure control
Special Application Focus:
Precision Ultra Low Pressure Gas Supply System |
Problem: There are very few if any commercial regulators capable of precisely controlling gas pressure
below 0.5 psig with varying flow rates.
Solution:
The LPR2 can be used in conjunction with an Equilibar Precision Back Pressure Regulator
and a flow control valve to provide incredible precision and responsiveness. By venting any gas flow
not required by the application, this system can accommodate forward or reverse gas flow at the application
without loss of accuracy.
