Air Heaters

Product catalog summary
Overview: This technical catalog from OSRAM SYLVANIA provides detailed information on Air/Inert Gas Heaters, focusing on product specifications, applications, and operational guidelines. It highlights the necessity of using these heaters exclusively with air or inert gases, cautioning against their use with explosive gases.
Product Applications: The heaters are adaptable for various industries, including aerospace, packaging, automotive, plastics/rubber, textiles, semiconductor/electronics, sterilization, and paper/printing. They are used for combustion simulation, high-speed sealing, adhesive curing, and hot air bonding, among other applications.
Product Features: The catalog details different heater models, each featuring quartz insulator tubes, built-in thermocouples for precise temperature control, and high-pressure capabilities. These heaters can achieve air temperatures up to 1600°F (871°C) and are engineered for efficiency and safety.
Specifications: Key specifications include maximum air temperatures, pressure limits, and blower compatibility. The heaters are CE compliant and come with stainless steel or quartz housings. They can control air temperatures up to 1400°F (760°C) with a precision of ±1°, and have a power range from 3.0kW to 36.0kW, compatible with 240/380/480V systems.
Control Systems: The document outlines closed-loop and open-loop control systems. Closed-loop systems utilize digital temperature controllers and thermocouples for precise regulation, while open-loop systems depend on manual adjustments.
Installation and Maintenance: Proper installation and maintenance are essential for optimal performance and longevity. Recommendations include selecting suitable air sources, minimizing air restrictions, and ensuring a clean, dry air supply.
Performance Data: Performance data for various heater models is presented through graphs and tables, showing temperature capabilities relative to air flow rates.
Accessories: A range of accessories is available, such as power controllers, thermocouple holders, and adaptors, to enhance the heaters' functionality and integration into different systems.
Performance: The heaters are designed for high pressure and high flow applications, capable of handling air/inert gas temperatures up to 1400°F (760°C). They feature the SureHeat overtemperature protection system and offer up to 192kW in a compact size.
Installation and Wiring Notes: S1 and S2 sensors are 'K' type thermocouples for measuring inlet and exit air temperatures. Detailed operating instructions are available online.
Technical Calculations: The document provides formulas for calculating air heater energy requirements, temperature conversions, air flow conversions, and wiring configurations for both single-phase and three-phase systems.
Contact Information: Contact details for OSRAM SYLVANIA are provided for orders and product information.
