Trane CNT2190 Pressure Control

Ensure critical protection for high-pressure circuits with the Trane CNT2190 Pressure Control. Specifically engineered for commercial and residential HVACR applications, this high pressure cutout switch monitors refrigerant discharge to prevent compressor damage from excessive head pressure. Featuring a robust 90-inch capillary tube and a 1/4-inch male flare connection, the CNT2190 provides a versatile installation footprint for tight cabinets and complex line sets. The unit is factory-calibrated for a high-side range of 90 to 450 PSI, functioning as a reliable auto-reset pressure switch that maintains system uptime without requiring manual intervention after a temporary spike. This HVAC high pressure control is a direct replacement for several legacy safety controls, offering precise setpoint accuracy for Trane compressor protection and general refrigeration duty. Built to withstand demanding thermal environments from -13°F to 158°F, the CNT2190 is a standard-issue component for technicians looking to restore factory-spec safety parameters to Trane air handlers and condensing units.

• Universal Compatibility: Includes a 1/4-inch male flare nut and 90-inch capillary for flexible routing and connection to Trane HVAC systems.
• Automatic Reset Logic: Eliminates nuisance lockouts by automatically restoring circuit continuity once system pressure falls below the differential threshold.
• High-Pressure Range: Supports precise monitoring up to 450 PSI, making it suitable for modern high-pressure refrigerants.
• Contractor Grade Construction: Designed for long-term durability in professional HVACR refrigeration service applications.

Is the Trane CNT2190 an automatic or manual reset switch?
This is an auto-reset pressure control, meaning the switch will automatically close and allow the system to restart once the pressure drops back within the safe operating range.

What is the connection type for this pressure control?
The Trane CNT2190 features a 1/4-inch male flare (SAE) connection, typically used with high-side service ports or tee-fittings.

Can this part replace other brands of pressure switches?
Yes, as a 90-450 PSI pressure control, it frequently serves as a direct cross-reference for specific Johnson Controls and Ranco series high-pressure cutouts; always verify the electrical rating and connection size.
