Description
The A/FS Series controllers are Low Limit controllers also known as “Freeze Stats”. These devices were designed for use on HVAC equipment requiring low-temperature cutout protection and in all ducts to prevent the cooling coils from freezing. The Freeze Stats should be mounted between the heating and cooling coils on the supply side of the fan unit.
Features:
- Adjustable trip point between 14 °F and 54 °F (–10 °C to 12 °C) gives flexible control for different system requirements.
- Manual reset option enhances safety by requiring human intervention after a freeze event.
- Vapor-filled copper capillary provides fast, reliable temperature response, even in stratified air.
- Built-in microswitch with SPDT (Form 1C) contacts rated up to 250 VAC / 15 A (8A) — ideal for control or safety cut-out.
- Durable NEMA 1 / IP40 enclosure: galvanized steel base with fire-retardant ABS cover.
- Long capillary lengths available (6′, 10′, 20′, or 50′), giving flexibility in where you mount the sensor.
- Operating temperature range of 14 °F to 131 °F, with humidity tolerance up to 95% RH (non-condensing).
- CE-approved and reliable for industrial and commercial HVAC applications.
