Thermal Resilience: Class F insulation allows for higher operating temperatures without compromising internal windings

Replacement motors usually do not include the capacitor

preventing unnecessary cooling load and humidity spikes

the manual reset is a deliberate design choice to ensure system inspection after a high-heat event

Built with a NEMA 2 (IP54) rated polymer housing

Sporlan 180399P Power Element 322057-301 Thermal Resilience: Class F insulationThe Sporlan 180399P (KT 46 SZ) is a replacement thermostatic power element designed for field servicing of Sporlan thermostatic expansion valves. This Type 46 element features a 60 inch capillary tube and is engineered for precise refrigerant metering in specialized R 404A and R 507 applications. Given the SZ charge characteristics, this element is optimized for sub zero temperature ranges, ensuring consistent superheat control and preventing
