Condensate Chambers

At Flowell, we understand that maintaining the efficiency and integrity of your pipeline system requires more than just durable materials—it demands precision-engineered components designed to withstand the unique challenges posed by gaseous and steam service lines. Our condensate chambers are built to do exactly that.

What Is a Condensate Chamber?

A condensate chamber, often referred to as a seal chamber or condensate pot, is a critical component used in instrumentation loops to collect condensate and foreign material from gas and steam lines. These chambers are strategically installed to prevent debris or unwanted liquids from reaching sensitive instruments, like pressure or differential pressure transmitters.

In systems where accuracy, performance, and safety are paramount, our condensate chambers provide the protective buffer necessary to maintain optimal operation. Whether used in high-temperature steam systems or corrosive gas environments, our chambers function as a reliable safeguard against contamination, pressure surges, and loss of seal integrity.

Our Design Philosophy

Every Flowell Condensate Chamber is engineered with performance, safety, and longevity in mind. We design our chambers to trap not only condensate but also particulates and contaminants that may accumulate over time. This helps reduce maintenance frequency, extend instrument life, and prevent costly downtime or measurement inaccuracies.

We believe in simplicity without compromise. Our standard offering features ½” FNPT top and bottom connections—ideal for most industrial and process control applications. These chambers integrate seamlessly into new or existing systems, and if your needs fall outside the standard, we offer a range of customizations to ensure a perfect fit.

Built for Demanding Conditions

Our condensate chambers are manufactured from pipe materials that match your system requirements. They’re available in standard wall thickness classifications, including Schedule 40, Extra Heavy (XH), and Double Extra Heavy (XXH). Each schedule option ensures that the chamber provides a pressure rating equivalent to the wall thickness of the matching pipe material.

We know that industrial systems don’t operate in ideal conditions—they face intense heat, pressure differentials, and, often, aggressive chemicals. That’s why our chambers are built with the same resilience and pressure capabilities as the piping they are installed alongside. You can rely on our chambers to maintain their integrity over long operational lifespans.

Key Applications

Condensate chambers are essential across a variety of sectors:

• Petrochemical Processing: Protect instrumentation in high-pressure gas lines and corrosive environments.
• Power Generation: Maintain measurement accuracy in high-temperature steam lines in boiler systems.
• Pharmaceuticals and Food & Beverage: Prevent cross-contamination in sanitary steam service systems.
• Refineries and Chemical Plants: Protect differential pressure transmitters from liquid intrusion or clogging.

If your application involves high-pressure steam, corrosive gases, or any service where condensate buildup is a risk, our condensate chambers offer unmatched performance and peace of mind.

Superior Liquid Seal Performance

One of the major advantages of using our condensate chambers is their ability to maintain a stable liquid seal. This is especially important in steam service lines where pressure transmitters rely on a consistent water column to function properly. Without this seal, instrument readings can be erratic or misleading.

Our chambers trap and retain a defined volume of liquid to act as a buffer, minimizing fluctuations and maintaining process consistency. This liquid seal helps isolate instruments from high-temperature or corrosive process media, protecting them from thermal shock and chemical attack.

Custom Configurations Available

While we provide a robust set of standard features, we understand that no two operations are the same. That’s why we offer flexible options for custom configurations. In addition to the standard ½” FNPT top and bottom ports, you can specify additional taps, alternative thread sizes, socket welds, or flanged connections.

Do you need different materials to match exotic alloys in your process line? We can fabricate condensate chambers using a wide range of stainless steel and alloy grades to suit your application’s chemical and thermal profile.

We also offer custom dimensions, capacities, and pressure ratings tailored to your system’s layout and needs. Just let us know your specs, and we’ll engineer the right solution.

Precision Fabrication and Testing

Quality is at the core of every chamber we produce. Our condensate chambers are fabricated using industry-approved welding and machining practices. After fabrication, each unit undergoes stringent quality checks to ensure dimensional accuracy and pressure integrity.

For customers requiring added assurance, we can perform hydrostatic or pneumatic pressure testing to verify chamber integrity. Upon request, welds can also be subjected to non-destructive examination (NDE), such as dye penetrant or radiographic inspection.

We take pride in our craftsmanship and back our products with performance documentation and traceability when needed.

Seamless Integration into Instrumentation Loops

Installing a Flowell condensate chamber is straightforward. The chamber is typically placed in the impulse line between the main process pipe and the differential pressure transmitter. Our standard ½” FNPT ports make threading and installation easy for most configurations.

For steam service, the chamber should be mounted below the transmitter to allow gravity to maintain the water column. For gas service, placement may vary depending on whether you’re draining condensate or capturing entrained particles.

We provide detailed guidelines on installation orientation and best practices to help ensure your chamber performs as intended. If needed, our team is available to consult on installation and integration.

Engineered for Reliability

System reliability starts with component dependability. That’s why we build our condensate chambers to stand up to harsh conditions, minimize maintenance demands, and protect the instruments you rely on for safe, accurate process control.

Our chambers are corrosion-resistant, structurally robust, and highly effective in isolating instruments from contaminating process fluids. They act as the first line of defense in complex systems, preventing minor issues from escalating into major failures.
