HEATED SAMPLE CONDITIONING |
|||||||||||||||||||||
|
The P53 Heated Sample Conditioning System ensures performance of gas analyzer by delivering a heated sample through patented technology to the analyzer. This avoids costly errors resulting from hydrocarbon dew point drop out by the maintaining at least 30ºF above the expected hydrocarbon dew point. |
The gas sample is heated inside of the regulator before and after the pressure is reduced eliminating hydrocarbon liquid condensation caused by the Joule Thomson effect during the pressure reduction. |

The Pony® Heated Probe Enclosure is designed to provide and maintain heat for the sample probe directly at the sample point with a P53 Heated Sample Conditioning System. The Pony® enclosure is an integral part of the P53, developed to install between 6” center-to-center thread-o-lets. |
Consisting of a molded, insulated, and weatherproof clam shell design, the Pony® enclosure provides easy maintenance with steel latches and chain to prevent loss of lid. Construction selections include hot press glass fiber reinforced polyester or stainless steel. |
