ZEECO PILOT TESTING ® Pilot Testing Per API 537 Flare systems operate as a critical safety device within facilities to protect nearby personnel and equipment. A stable, reliable, and robust pilot is the most critical component in a flare system because the pilot initiates and ensures combustion. Zeeco is proud to offer pilots tested and proven to meet and exceed American Petroleum Institute (API) 537 standards. Given the criticality of flare pilots, industry leaders and international experts came together to set API criteria for evaluating acceptable flare pilot performance. Using pilots that are tested and proven to meet the criteria assures equipment operators and the public that a flare pilot will perform reliably. API is responsible for determining and updating nearly 700 globally accepted industry standards designed to set the expectations for real world performance. Zeeco has installed an API-recommended test stand to test and prove the suitability of our pilot designs, and to develop and test future pilot technologies. The ZEECO® HSLF-Z pilot has been tested and proven to far exceed the minimum standards of API 537. While API 537 requires that a pilot stays lit when subjected to 140 km/h (85 mph) wind speeds and 5 cm/h (2 in/h) of rainfall, the HSLF-Z pilot has been proven to stay lit under punishing hurricane force 274 km/h (170 mph) winds in the face of 131 cm/h (51 in/h) of rainfall. To ensure your flare equipment meets safety expectations and API 537 requirements, choose a ZEECO flare pilot. HSLF Flare Pilot (Still image from live pilot test video.)
