Automation Components Inc (ACI) A/FLS-20-M Freeze Stat

The Automation Components Inc (ACI) A/FLS-20-M Freeze Stat is a high-performance low temperature cutout control designed to protect commercial HVAC systems from costly coil damage. Featuring a 20-foot vapor-filled copper capillary, this manual reset freeze stat provides comprehensive coverage across the face of heating and cooling coils. As an essential HVAC safety limit switch, the A/FLS-20-M monitors air temperature stratification and triggers a system shutdown if the sensed temperature drops below the user-defined setpoint. This model is engineered with a 4-wire, two-circuit configuration, allowing it to simultaneously open the main load contacts to stop the fan and close auxiliary contacts to activate a remote alarm or building management system notification. With an adjustable range of 15 to 55°F, it offers precise low limit protection in a durable NEMA 1 rated metal enclosure. Ensure your air handling units remain operational and damage-free with this reliable electromechanical sensing solution.

Key Benefits

  • 20-Foot Capillary Length: Provides extensive coverage for large coils to detect localized cold spots.
  • Manual Reset Security: Ensures a technician inspects the system before restarting after a low-temperature trip.
  • Dual Circuit Control: Simultaneously shuts down fans while signaling an alarm for immediate response.
  • Adjustable Setpoint: Field-adjustable trip points between 15°F and 55°F for versatile application needs.
  • Rugged Construction: Features a galvanized steel NEMA 1 enclosure with a 1/2-inch conduit knockout for secure installation.

Common Questions

How do I install the capillary for maximum protection?

The sensing element should be installed in a horizontal serpentine pattern across the downstream side of the coil to ensure it monitors the entire airflow path for temperature stratification.

What is the difference between manual and automatic reset models?

Manual reset models like the A/FLS-20-M require a physical button press to restore operation, whereas automatic models reset once the temperature rises above the differential.

Can this unit be mounted in any orientation?

For accurate performance, the control case should be mounted with the element bellows pointing down and located in an area warmer than the setpoint.
