Hanover Indirect Line Heater 48" x 17'6" 1.5MM BTU

The Hanover Indirect Line Heater is a robust, skid-mounted heating system designed for the oil and gas industry, particularly for heating natural gas, crude oil, or process fluids to prevent hydrate formation and improve flow characteristics. Manufactured by The Hanover Company in 2003, this unit features a 48-inch diameter shell with a length of 17 feet 6 inches, housing a high-pressure coil bundle rated for 1.5 million BTU per hour. It operates by circulating a heat transfer medium (typically glycol-water mixture) around the coil, indirectly heating the process fluid without direct flame contact, enhancing safety in hazardous environments. Key benefits include high pressure tolerance up to 15,000 PSIG on the coil, efficient heat transfer with a total coil area of approximately 137.2 square feet, and suitability for remote field operations. Drawbacks may include the need for periodic coil cleaning due to potential fouling, as evidenced by rust and residue in the provided images, and higher initial costs compared to direct-fired heaters. This used unit shows signs of wear, including external rust and internal corrosion, but offers advantages over similar products like those from competitors (e.g., Sivalls or Natco) through its durable construction and customizable coil configurations for extreme pressures. Ideal for upstream applications in cold climates or high-pressure pipelines.
