Start Capacitor for Duratech DURA-18, DURA-22 / DURA+19 Heat Pumps
Genuine OEM Compressor Start Capacitor for 2014+ Models
As a retailer of pool and spa heating equipment, I supply genuine OEM start capacitors specifically designed for Duratech DURA-18, DURA-22, and DURA+19 heat pump compressors. This factory-specified component provides the essential electrical boost required for reliable compressor starting.
Product Overview
This start capacitor delivers the high-torque electrical assistance necessary to initiate compressor motor operation in your Duratech heat pump. Unlike run capacitors that provide continuous support, the start capacitor engages briefly during startup to overcome initial motor resistance, then disengages once the compressor reaches operating speed.
Key Features
OEM Specification
Manufactured to Duratech’s exact electrical and physical specifications for DURA-18, DURA-22, and DURA+19 models from 2014 onwards.
High Starting Torque
Engineered to provide the precise capacitance surge required for smooth compressor motor starting under varying ambient conditions.
Multi-Model Compatibility
Compatible across DURA-18, DURA-22, and DURA+19 models, simplifying parts inventory for service applications.
Applications
This start capacitor is essential for reliable compressor starting in compatible Duratech heat pumps. Common replacement indicators include compressor failing to start, hard starting with clicking sounds, thermal overload tripping, reduced starting reliability in cold weather, or visible capacitor deterioration.
