Johnson Controls A19ADB-11 Utility Thermostat Refrigerant High-dielectric ceramic insulator prevents signal

High-dielectric ceramic insulator prevents signal leakage to the chassis ground

facilitating a robust braze-in connection that eliminates common leak points found in flare-style fittings

offering the structural integrity required to withstand high-pressure differentials common in industrial refrigeration cycles

it is best practice to verify chemical compatibility with the seal material before utilizing it for non-steam fluids

Johnson Controls A19ADB-11 Utility Thermostat Refrigerant High-dielectric ceramic insulator prevents signalThe Johnson Controls A19ADB 11 is a commercial grade remote bulb temperature control designed for extreme high temperature monitoring. This single stage, manual reset thermostat is engineered to open the circuit on temperature rise, making it a critical safety limit for heating systems. Operating on multiple line voltages (120 208 240 VAC), it features a liquid filled sensing element that ensures reliable performance across a broad 200F to 550F range.
