Condensate Chambers & Seal Pots (CC)
To Separate Fluids and Protect Instrumentation
For Steam and Corrosive Fluids
- Line size: 2 to 4”
Industry-Leading Condensate Chambers for Protecting dP Instrumentation
Condensate chambers, also called seal pots, are pressure vessels that protect pressure sensing transmitters from the damaging effects of steam and corrosive or aggressive line fluids. In steam service, the transmitter impulse line is bottom-mounted and kept filled with condensate from the transmitter sensor up to a controlled level in the pot. This condensate “seal” isolates the transmitter from direct steam exposure while still transmitting pressure changes accurately.
Pressure variations from the flowing fluid are communicated through the condensate pool surface to the transmitter sensor, helping maintain stable measurement and extending instrument life.
Condensate Chamber & Seal Pot Key Benefits:
- Transmitter Protection: Shields sensitive sensing elements from hot steam and corrosive fluids.
- Stable Pressure Transmission: Uses a condensate seal to reliably transfer pressure variations to the sensor.
- Improved Instrument Longevity: Reduces thermal and chemical stress that can shorten transmitter life.
- Versatile Service Compatibility: Suitable for steam, water, hydrocarbons, process liquids, and gas applications.
Typical applications include steam systems, water service, hydrocarbon and process liquid lines, and gas process measurement. Common industries include oil production and refining, chemical and petrochemical facilities, power generation plants, and steel plants, anywhere transmitters require added protection in harsh process conditions.

Applications
Oil and Gas Production and Refining
Seal pots isolate transmitters from harsh hydrocarbons and high temperatures. They are commonly used on steam, hydrocarbon, and gas process lines where reliability is critical.
Steel and Heavy Industrial Facilities
In heavy industrial environments, condensate chambers help shield transmitters from heat and contaminants in steam and utility services. This improves reliability and reduces downtime.
Power Generation
Power facilities use condensate chambers on steam and water systems to reduce thermal exposure at the transmitter. This supports more stable dP measurement and easier maintenance.
