Benefits and Features Improved Productivity The X-element discharges air at a temperature approximately 22 ºC (40 ºF) lower than the saturation temperature of steam. With high-capacity venting capability, it rapidly vents air and lessens residual air inside equipment. Improved heating efficiency and faster increases in temperature. Application Areas These air vents are especially recommended for the following applications: Processes with batch operation and therefore requiring the venting of large quantities of initial air. Processes in which hot air during operation often causes malfunctions. Main Applications Jacketed kettles, vulcanizers, presses, dryers, heat exchangers, steam transport piping pipe-ends, etc.
