Scrubber Level System Tools
Scrubber Level Control System Emissions Calculator (.xls, 613KB)
The SLS Emissions Calculator allows you to plug in application information, such as ambient temperature, dump frequency, dump rate and supply pressure, and provides the total system emission of gas per hour.
DVU Selection Guide (.zip, 327KB)
The DVU Selection Guide selects the appropriate dump valve model for the user using a series of calculations. This calculation is obtained after the user inputs application information such as diameter of vessel, duration of dump cycle, vessel pressure and pressure at outlet of DVU.
New Product Release: MLS
Murphy is proud to announce that effective immediately, the MLS is officially approved for production release.
Purpose
The MLS Series connects directly into the gas scrubber wall and can be used with a Murphy weld collar or Murphy external float chamber and is available in both 2”NPT and 1-1/2” NPT models.
The MLS Series can replace many existing electric liquid level switches currently being offered by Murphy including the L1200 and LS200. The Stainless Steel construction makes the MLS a perfect single model for all applications without the need for special part numbers or multiple items stocking.

Its primary features/benefits are:
- Seal free, stainless steel construction
- Clean Magnet Design
- Trip on rising or falling without need to rotate the body
Agency Approvals:
- CSA C/US Class I, Div. 1 Grps. B, C & D
- NACE MR0175 compliant
- Canadian Registration Number
- MLS-020, 0F01476.2
