Shand & Jurs 97101E High-Pressure Electric Drip Trap

For remote biogas operators, RNG conditioning engineers, and SCADA-integrated plant teams, the Shand & Jurs 97101E High-Pressure Electric Drip Trap automates condensate removal from pressurized biogas, landfill gas, and vapor recovery piping while maintaining a fully sealed process.

Unlike manual high-pressure drip traps that require scheduled operator rounds, the 97101E uses an electrically actuated discharge valve that removes liquid at timed intervals or under control-system command, eliminating routine confined-space exposure and enabling coordinated drainage across distributed collection points.

The sealed chamber is rated for 100 PSIG working pressure with threaded connections, and a 4- or 6-quart reservoir matches accumulation between drainage events. Corrosion-resistant construction, optional explosion-proof actuators, and position feedback switches support reliable service on wet, acidic gas in hazardous-area installations.

The automated high-pressure design is applied at remote, unattended, or reliability-critical facilities, integrating condensate drainage with plant SCADA as part of a complete monitored gas safety and conditioning architecture.

Features

Automates condensate removal without operator intervention, enabling timer-based or remote drainage on pressurized biogas, landfill, and vapor recovery piping.

Supports scheduled or SCADA-triggered drainage, placing condensate removal alongside valve, regulator, and flame arrester status in monitored architectures.

Maintains gas containment during drainage on pressurized lines, eliminating the need to depressurize or break containment during routine cycles.

Position feedback and external panels confirm each drainage event, supporting alarm-based maintenance strategies and auditable operating records across the site.

Optional stainless steel body and corrosion-resistant internals provide reliable service in wet, acidic biogas, digester gas, and landfill gas streams.

Installs at piping low points to protect downstream flame arresters, control valves, and fuel trains from moisture carryover and liquid slugs.

Applications

Biogas and Digester Systems: Drains condensate from pressurized digester gas piping where automated drainage reduces operator exposure and maintains continuous conditioning flow.
Landfill Gas: Removes moisture from pressurized landfill gas collection piping upstream of blowers, flares, and engines, preventing slug flow and combustion upset.
RNG Conditioning: Supports renewable natural gas conditioning trains where predictable drainage is required between upgrading, compression, and custody transfer stages.
Vapor Recovery: Installs on pressurized vapor recovery headers where automation eliminates the need for routine manual draining during active collection.
Remote and Unattended Sites: Supports distributed and remote facilities where operator rounds are impractical and drainage must occur on schedule or SCADA command.
Cold Climate Installations: Optional insulation jackets and freeze protection enable reliable automated drainage in outdoor and cold-weather service environments.

When do I specify the 97101E instead of the 97100E?

−

Select the 97101E whenever the piping operates above the 25 PSIG envelope of the 97100E. The 97101E is rated for the full 100 PSIG service pressure typical of pressurized biogas, landfill gas, and vapor recovery headers, with the same SCADA-ready automation as the low-pressure version.

How does the electric actuator integrate with plant SCADA?

An optional control panel interface and position feedback switch allow each drainage event to be triggered, monitored, and logged by the plant control system. Drainage can be scheduled on a timer, command-driven from SCADA, or alarm-based, and each cycle produces a confirmable open/close signal back to the host.

Is an explosion-proof version available?

Yes. An explosion-proof actuator is available for hazardous-area installations, complementing the standard NEMA 4X/7 enclosure for wet and corrosive service. Area classification should be confirmed against the applicable local electrical code before specifying the actuator option.

What materials are available for corrosive service?

The 97101E is offered in carbon steel or stainless steel construction. Stainless is recommended for saturated biogas, landfill gas, and any stream with elevated H₂S or moisture content where long-term corrosion resistance is a priority.

Can the 97101E be operated during power loss?

The 97101E is designed for normal operation under the electric actuator. Where a manual backup is required on pressurized piping, the 97101 Manual Drip Trap is used in parallel or as an alternate at that drip leg; the paired approach supports both automated and operator-initiated drainage at a single low point.

What is the operating temperature range?

The 97101E is rated for saturated gas service, matching typical biogas, digester gas, landfill gas, and RNG conditioning conditions. For freezing ambient conditions, an insulation jacket option with a maintained heat source preserves drainage reliability through winter operation.

How does automated drainage reduce operating cost?

Replacing manual rounds with scheduled or SCADA-triggered drainage reduces field labor, eliminates confined-space exposure on routine draining, and prevents the corrosion and downstream damage that missed drainage cycles cause. Alarm-based maintenance strategies also replace calendar servicing with condition-based intervention.

Summary

With over a century of tank-safety heritage, Cognesense delivers the Shand & Jurs 97101E High-Pressure Electric Drip Trap for pressurized biogas, landfill gas, and vapor recovery piping that must drain reliably without operator rounds. Its actuated positive shutoff valve, 100 PSIG sealed chamber, and SCADA-ready feedback integrate condensate removal into the plant’s monitored gas safety architecture, reducing field labor while protecting downstream flame arresters, flares, and blowers. For remote and reliability-critical sites, the 97101E is trusted wherever you need to measure, monitor, and protect what matters most.
