Fantini Cosmi

Fantini Cosmi pressure switches span 1 to 300 bar. The B13CN bellows switch handles 1–10 bar for low-pressure pneumatic circuits. Diaphragm models like the B12DN operate 5–16 bar, B12GNY covers 25–150 bar, and the B12HNY reaches 60–300 bar for high-pressure hydraulic applications. The B12CRNY variant includes vacuum-rated models from −0.2 to 8 bar. Differential settings range from fixed to adjustable (0.6–40 bar depending on model), allowing precise on-off hysteresis tuning for pump protection and load control.

The C16I ambient thermostat uses vapor-tension sensing to modulate or switch boiler burners in response to room temperature. It features two-pole cable termination for direct wiring to boiler control panels and carries ErP Class I classification, meeting EU energy-efficiency directives for space-heating appliances. Typical applications include wall-mounted room-stat installations in residential and light-commercial heating plants, where the thermostat signals the control module to adjust or cut fuel supply based on setpoint deviation.

Both are immersed-electrode level regulators with IP68 protection and stainless-steel bodies for tank and boiler applications. The A96D features a 15-meter polyurethane cable rated to 4 bar and 60 °C, suited for mobile or extended-distance sensor placement. The A95B uses a 3-meter PVC cable, rated 10 bar and 60 °C, with 10(4)A switching current at 250 VAC, typically for fixed internal-tank or close-proximity installations. Cable material and length determine application fit; polyurethane offers better chemical resistance and flexibility.

Yes. Models like the B12DN, B12GNY, and B12HNY are designed for both fluid media. They use stainless-steel diaphragm or piston sensing elements and G 1/4 threaded or flange ports compatible with standard manifold assemblies. IP40 enclosures protect against dust and liquid splashes in industrial environments. Differential settings ensure stable switching and prevent chatter in pump-pressure control, compressor unload, and accumulator protection circuits.

Key parameters include port type (G 1/4 threaded, G 1/4 flange, or SAE NG10 cavity), protection rating (IP40 or IP68), switching current (typically 5A–16A at 250 VAC), and differential range (fixed or adjustable). Cable-exit termination (two-pole, connector, or flange) must match control-panel wiring. Pressure range, setpoint accuracy (±10 %), and sensing-element material (diaphragm, piston, or bellows) define functional fit. 3G Electric provides full spec sheets and can advise on substitutions or custom setpoint configurations.

3G Electric stocks Fantini Cosmi pressure switches, thermostats, and boiler control components across 169+ SKUs, allowing next-day or rapid shipment for urgent maintenance. Common wear items—such as the B12HNY pressure switch (used for fuel-pump shutdown at overpressure) and ambient thermostats—are maintained in inventory. Technical documentation, setpoint tables, and cross-reference guides are available. For obsolete models or specialized configurations, 3G Electric can source direct from manufacturer or recommend current-generation equivalents.
