Shand & Jurs 97110 Automatic Drip Trap

For digester operators, utility gas engineers, and remote-site maintenance teams, the Shand & Jurs 97110 Automatic Drip Trap provides continuous condensate removal from low-pressure gas piping where liquid accumulates faster than routine inspection intervals allow, preventing flow restriction, regulator instability, and hydraulic shock.

Unlike manual or electric drip traps that rely on operator rounds or control system commands, the 97110 uses a float-operated stopper valve that opens automatically when condensate reaches the operating level and reseats once the liquid drops, keeping a continuous liquid seal during discharge to prevent gas escape or air ingress.

Condensate collects in a 2- or 4-quart chamber rated for 5 PSIG standard or 25 PSIG optional service, with 1-inch NPT connections suited to direct installation in condensate legs. Aluminum or 316 stainless steel body options match service corrosivity, and a note: the 10 States Standard does not permit float-operated traps in its regulated applications.

The automatic float design is applied where accumulation is continuous or unpredictable, eliminating manual servicing while maintaining stable gas flow and protecting downstream regulators, valves, and burners in unattended or remote installations.

Features

Automatically opens the drain when condensate reaches the operating level, closing again as the liquid drops, with no operator action required.

A liquid barrier remains above the outlet during discharge, preventing gas escape or air ingress throughout each drainage cycle.

Removes condensate without operator intervention or routine manual servicing, eliminating scheduled rounds for unattended gas piping low points.

Supports continuous drainage in low-pressure gas piping with a 2- or 4-quart reservoir sized for distributed drip legs across the site.

Installs directly at piping low points without additional adapters, simplifying retrofit into existing drip legs, headers, and equipment drops.

Aluminum and stainless components withstand wet gas and contaminated condensate, with a 316 stainless steel body option for aggressive service.

Applications

Unattended Gas Piping: Drains remote or distributed drip legs continuously, removing the need for manual rounds on unattended low-pressure gas systems.
Headers and Manifolds: Removes condensate at distribution headers so downstream regulators, valves, and burners continue to receive a stable, dry gas supply.
Condensate Legs: Fits purpose-built drip legs on utility gas and process gas piping where float operation is permitted by the applicable installation code.
Continuous Drainage: Handles unpredictable or continuous condensate accumulation where manual drainage intervals would be exceeded by the liquid generation rate.
Utility Gas Distribution: Installs on utility fuel gas systems where low-pressure float-operated drainage is accepted practice under the applicable local code.
Remote Facilities: Protects unattended drip legs on remote sites where automatic operation eliminates the need for routine operator drainage rounds.

How does the float-operated drain prevent gas release?

−

A liquid seal remains above the drain outlet during discharge, so the gas path never opens to atmosphere during drainage. The float lifts the stopper valve when condensate reaches the operating level and reseats as the level drops. This continuous liquid seal is the fundamental safety feature of the 97110 and the reason it can operate unattended.

Can the 97110 be used on biogas under the 10 States Standard?

No. The 10 States Standard does not permit float-operated drip traps in its regulated applications. For biogas and digester gas under that standard, select the 97100 Manual Drip Trap for attended sites or the 97100E Electric Drip Trap for SCADA-integrated operation. The 97110 is appropriate for utility fuel gas and other low-pressure services where float operation is accepted by the applicable local code.

What is the difference between the 2-quart and 4-quart chambers?

Chamber size sets the buffer between drainage cycles. A 4-quart reservoir gives a longer dwell between cycles on wetter gas or higher accumulation rates; a 2-quart reservoir suits drier service or distributed drip legs where continuous, more frequent drainage is acceptable. Both use the same 1-inch NPT connections and operate up to 5 PSIG standard or 25 PSIG optional.

What materials are available for corrosive service?

The 97110 is offered with aluminum or 316 stainless steel body construction, with 304 or 316 stainless internal components and NBR seals. Specify the 316 stainless body and stainless internals for aggressive or sour gas streams where long-term corrosion resistance is required.

How is the 97110 installed?

Install at a piping low point in a vertical drip leg so accumulated liquid gravity-feeds into the reservoir. The 1-inch NPT connections allow direct threaded installation without flanges or adapters. Discharge should be routed to a safe drain or capture vessel per site procedure.

When should I pick the 97100 or 97100E instead?

Select the 97100 Manual Drip Trap for attended sites where operator-controlled drainage is preferred or required by code, and the 97100E Electric Drip Trap where drainage must be timed, remotely triggered, or integrated with plant SCADA. The 97110 is the right choice specifically when continuous automatic drainage without electric power or operator involvement is acceptable.

Does the trap require routine maintenance?

The 97110 requires minimal routine maintenance: periodic inspection of the float and stopper valve, verification of the seal, and cleanout of accumulated solids. The float-operated design has no timers, controls, or power supply to service, which is the principal operating-cost advantage of the device on unattended low-pressure gas systems.

Summary

With over a century of tank-safety heritage, Cognesense delivers the Shand & Jurs 97110 Automatic Drip Trap for low-pressure utility and process gas piping where continuous condensate accumulation would otherwise outrun operator rounds. Its float-operated stopper valve and continuous liquid seal drain liquid automatically without releasing gas, while aluminum or 316 stainless construction matches the corrosivity of the service. For unattended low-pressure installations outside 10 States Standard jurisdictions, the 97110 is trusted wherever you need to measure, monitor, and protect what matters most.
