Shand & Jurs 97100E Electric Drip Trap

For biogas plant operators, digester gas engineers, and remote-site maintenance teams, the Shand & Jurs 97100E Electric Drip Trap removes accumulated condensate from low-pressure gas piping on command, schedule, or supervisory control, rather than by manual operator intervention.

Unlike manual drip traps that require routine operator presence, the 97100E uses an electrically actuated ported disc valve that seals the inlet gas path before opening the drain, enabling timed or SCADA-initiated drainage while maintaining continuous gas containment across the piping system.

Condensate collects in a 3- or 6-quart reservoir rated for 5 PSIG standard or 25 PSIG optional service, with 1-inch NPT connections and a NEMA 4X/7 actuator suitable for classified gas areas. A visual open/closed indicator and manual handwheel override support commissioning and power-loss conditions.

The electrically actuated design is applied where drainage timing must be coordinated across multiple collection points, remotely initiated, or performed without exposing personnel to the piping environment, across digester gas, landfill gas, and monitored utility gas systems.

Features

Enables drainage without personnel present while maintaining positive gas isolation through a sequenced inlet-then-drain opening cycle.

Integrates condensate removal into SCADA or scheduled maintenance routines, replacing manual rounds with coordinated, programmable drainage events.

Confirms open or closed valve position before maintenance access, supporting safe lockout and clear status verification at the device.

Suitable for classified gas areas and outdoor installations without additional environmental protection or intermediate weatherproofing equipment.

Maintains operability during commissioning or power loss, allowing site personnel to drain condensate without waiting for control system restoration.

Coordinates drainage across multiple collection points from a single external panel, with optional data transmission back to the plant SCADA.

Applications

Remote Biogas Sites: Drains condensate on unattended digester gas, landfill gas, and RNG sites where scheduled operator rounds are impractical or uneconomical.
SCADA-Integrated Piping: Fits monitored gas networks where condensate removal must be triggered, logged, and confirmed alongside other valve and regulator operations.
Equipment Drops: Protects individual fuel drops feeding burners, boilers, and flares by removing liquid on schedule, upstream of control valves and ignition trains.
Utility Gas Systems: Installs on attended utility gas piping where automation reduces operator exposure during routine drainage of confined or classified spaces.
Classified Gas Areas: NEMA 4X/7 actuator housing suits hazardous-area installations without additional enclosures, simplifying specification for digester and landfill service.
Coordinated Multi-Point Drainage: Drains multiple drip legs in a managed sequence, preventing the pressure disturbances that uncoordinated manual draining can introduce.

How does the 97100E differ from the manual 97100?

−

The 97100E adds an electric actuator that rotates the same ported disc valve used in the 97100, enabling timer-based or SCADA-triggered drainage instead of operator-initiated rounds. Mechanically the gas path is identical: the inlet seals before the drain opens, so methane does not escape and air does not enter. The electric version is the right choice where drainage must occur on schedule or command without on-site personnel.

Can the 97100E operate during a power loss?

Yes. A manual handwheel override is included so site personnel can drain condensate during commissioning, power loss, or controls maintenance. The sequenced gas-path sealing behavior is preserved in manual operation, so the device stays safe to operate even when the electric actuator is unavailable.

Is the actuator suitable for classified gas areas?

The actuator is supplied in a NEMA 4X/7 enclosure, which is rated for wet, corrosive, and hazardous-location service. This means the 97100E typically installs in digester gas, landfill gas, and biogas piping without additional explosion-proof housings. Always confirm the area classification and local electrical code before installation.

How are multiple drip traps coordinated across a site?

An optional external control panel allows multiple 97100E units to be coordinated from a single location and, where configured, to transmit status back to the plant SCADA. Coordinated sequencing prevents the pressure disturbances that independent manual draining can introduce and produces an auditable record of each drainage event.

What reservoir size should I specify?

Size the reservoir against the expected condensate accumulation rate and the drainage interval configured in the controller. A 6-quart chamber suits wetter service or longer dwell between drain events; a 3-quart chamber is well matched to drier gas or more frequent cycling.

Is an insulation jacket needed outdoors?

An optional insulation jacket is available for cold-climate service and requires a maintained heat source under the jacket. Use it where ambient conditions would otherwise freeze accumulated condensate and block drainage between cycles.

When is the 97101E the right device instead?

Use the 97101E High-Pressure Electric Drip Trap where the piping operates above the 25 PSIG envelope of the 97100E. The 97101E carries the same automated behavior but is rated for service up to 100 PSIG on pressurized biogas, landfill gas, and vapor recovery headers.

Summary

With over a century of tank-safety heritage, Cognesense delivers the Shand & Jurs 97100E Electric Drip Trap for biogas, digester gas, and utility fuel gas piping that must drain on schedule or command rather than on operator rounds. Its sequenced ported disc valve, NEMA 4X/7 actuator, and manual handwheel override maintain positive gas containment during every drainage event, whether triggered by a local timer, a SCADA command, or a commissioning technician. For remote and monitored sites, the 97100E is trusted wherever you need to measure, monitor, and protect what matters most.
