What is the difference between TD32F and TD32FLC variants?

The TD32FLC is a low-capacity variant specifically designed for low-load applications such as steam mains drainage. Standard TD32F units are suited for higher condensate loads in process applications.

When should I choose the TD32FA or TD32FALC with anti-air-binding disc?

Select the anti-air-binding variants when your system experiences air accumulation during start-up or when rapid air removal is critical. Note that these variants have a lower maximum operating temperature of 255°C compared to 400°C for standard versions.

What is the maximum backpressure the TD32F can handle?

The TD32F can operate with a maximum backpressure of 80% of upstream pressure. A non-return valve is recommended when discharging into return lines where backpressure is present.

What is the correct installation orientation for the TD32F?

The trap must be installed with the capsule in a horizontal plane and the cover facing upward. Installing a diffuser is recommended when discharging to atmosphere.

Are spare parts available for field maintenance?

Yes, the TD32F is a maintainable trap. Spare parts include replacement discs, strainer screens, strainer cap gaskets, and optional insulating covers for DN15 and DN20 sizes.

Overview

The Spirax Sarco TD32F is a maintainable, medium-pressure flanged thermodynamic steam trap designed for reliable condensate removal in industrial steam systems. It features an integral strainer screen that protects internal components from dirt and debris, reducing maintenance requirements and improving operational reliability.

The TD32F series includes multiple variants to suit different application needs. The TD32FLC is engineered specifically for low-load applications such as steam mains drainage. The TD32FA and TD32FALC variants incorporate an anti-air-binding disc that ensures prompt air removal during start-up, making them suitable for systems where air accumulation can impede performance.

Constructed with a stainless steel body and internals, the TD32F is built to withstand demanding industrial environments. The trap operates on the thermodynamic principle, using the difference in velocity between steam and condensate to open and close the disc, providing efficient and automatic condensate discharge.
