Product Description

Frequently Asked Questions

What is the Fantini Cosmi transparent siphon used for?

The Fantini Cosmi transparent siphon is a switching device for thermal applications, primarily used in heating system monitoring and control. It connects to level controls via a G 3/8" male connection and handles up to 160 °C and 10 bar, making it suitable for industrial heating circuits.

What are the specifications of the Fantini Cosmi transparent siphon?

The Fantini Cosmi transparent siphon has a G 3/8" male connection, a maximum operating pressure of 10 bar, and a maximum temperature of 160 °C. It is designed for use with stainless steel electrodes (AISI 303) sold separately, such as the 3G-CBM-03500 (1 m) or FAN02022 (2 m).

Where to buy the Fantini Cosmi transparent siphon in Singapore?

You can source the Fantini Cosmi transparent siphon through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility, providing technical support for thermal applications. Contact us for pricing and lead time on this item.

How to install the Fantini Cosmi transparent siphon?

Install the Fantini Cosmi transparent siphon by connecting its G 3/8" male thread to the system. A single-pole flexible cable (not supplied) links the siphon to the level control. The electrode probe (e.g., 3G-CBM-03500) is also not included and must be ordered separately. Ensure temperature and pressure stay within 160 °C and 10 bar.
