The York S1-373-23068-008 Heat Exchanger is an 8-tube aluminum assembly engineered for high-efficiency thermal transfer in residential and light commercial HVAC systems

Reduced Hysteresis: Flexible material properties minimize internal resistance

Copeland 998-0540-00 Limit Switch R-134A While a 2-pole contactor technicallyThe Copeland 998 0540 00 220F Limit Switch is a critical thermal protection component designed for commercial refrigeration and HVAC compressor safety. This discharge line thermostat monitors internal temperatures to prevent compressor overheating, effectively acting as a high limit cutoff. Engineered with a 220F trip point, the switch triggers when the discharge gas temperature reaches the safety threshold, interrupting the control circuit to protect
