The Hoffman 17C-2 Steam Trap is a high-performance automatic air venting steam trap designed for use in steam heating systems. This AP 1/2 size trap is engineered to efficiently remove condensate and excess air from the steam line, ensuring optimal system performance and energy efficiency.
The 17C-2 trap features a unique thermostatic disc design that opens and closes based on steam temperature. As the steam temperature rises above the set point, the disc opens, releasing any accumulated condensate and excess air. Once the steam temperature drops, the disc closes, trapping the steam in the system and preventing the loss of valuable heat.
The trap body is constructed of high-quality cast iron, providing superior durability and resistance to corrosion. The trap inlet and outlet connections are threaded for easy installation and can be configured for either horizontal or vertical applications. The trap also includes a built-in drain for easy maintenance and cleaning.
The Hoffman 17C-2 Steam Trap is designed to handle steam pressures up to 15 psi and temperatures up to 400 F. It is suitable for use in a wide range of industrial and commercial applications, including HVAC systems, process heating, and steam boiler feed systems.
The trap is also equipped with a non-clogging, self-cleaning mechanism that prevents the accumulation of debris and mineral buildup, ensuring reliable operation and long service life. The trap's compact size and low profile design make it an ideal choice for applications where space is limited.
Installation of the Hoffman 17C-2 Steam Trap is straightforward and can be completed without the need for special tools or extensive plumbing modifications. The trap is shipped with all necessary mounting hardware and includes clear installation instructions to ensure a successful installation.
In summary, the Hoffman 17C-2 Steam Trap is a high-performance, reliable, and durable automatic air venting steam trap that is ideal for use in steam heating systems. Its unique thermostatic disc design, robust construction, and easy installation make it a top choice for industrial and commercial applications where efficient steam system operation is essential.
The Hoffman 17C-2 Steam Trap AP 1/2 is a popular automatic air venting steam trap model from Hoffman Engineering. This trap is designed to remove condensate and air from steam lines, ensuring efficient steam distribution in industrial processes. Let's discuss the pros and cons of buying a Hoffman 17C-2 Steam Trap AP 1/2.
Pros:1. Reliable Performance: The 17C-2 trap is known for its robust design and dependable performance in various industrial applications. It effectively separates condensate and air from steam lines, maintaining the steam quality and efficiency.
2. Easy Installation: The trap is relatively easy to install, with a simple piping arrangement and no external controls or power requirements.

5. Suitable for High-Temperature Applications: The trap can handle high-temperature steam, making it suitable for use in various industrial processes.
Cons:1. Limited Capacity: The 17C-2 trap is only suitable for low to medium steam flow rates, making it less ideal for applications requiring high steam volumes.
2. No Temperature Compensation: The trap does not offer temperature compensation, which could affect its performance in applications with significant temperature fluctuations.
3. Manual Drainage Required: While the 17C-2 trap is self-cleansing, manual drainage is required to remove any accumulated dirt or debris.
4. Limited Applications: The trap is designed primarily for automatic air venting applications and may not be suitable for other steam trap functions like liquid separation or level control.
Conclusion:The Hoffman 17C-2 Steam Trap AP 1/2 offers reliable performance, easy installation, a long service life, and cost-effectiveness, making it an excellent choice for low to medium steam flow automatic air venting applications in industrial processes. Its limitations include limited capacity, no temperature compensation, and manual drainage requirements.
Recommendation:If your industrial process requires a steam trap capable of handling high steam volumes, you may want to consider other models with higher capacity and temperature compensation capabilities. However, if you're looking for a cost-effective, reliable, and easy-to-install automatic air venting steam trap for low to medium steam flow applications, the Hoffman 17C-2 Steam Trap AP 1/2 is a solid choice.
