Danfoss 7701038 Start Kit
The Danfoss 7701038 Start Kit is a critical field-service component designed for high-torque applications where single-phase compressors encounter significant starting resistance. Engineered specifically for Danfoss reciprocating compressors, this kit facilitates reliable startup under high differential pressures, common in refrigeration and air conditioning systems utilizing polyolester (POE) lubricants or mineral oils. The assembly features a high-grade start capacitor and a potential relay, ensuring the start winding is energized only during the initial torque phase to prevent thermal overload. This compressor hard start kit is essential for maintaining system stability in environments where voltage fluctuations or long refrigerant piping runs increase mechanical load. By optimizing the electrical phase displacement, the 7701038 reduces the duration of high inrush current, protecting the motor windings from excessive heat and mechanical stress. Field installation is streamlined via standardized spade terminals, making it a standard replacement part for HVACR contractors servicing commercial or residential refrigeration platforms.
- Enhanced Starting Torque: Provides the necessary electrical boost to overcome high-head pressures in Danfoss SC and TL compressors.
- Potential Relay Integration: Precisely disconnects the start capacitor once the motor reaches optimal RPM, preventing winding damage.
- Universal Refrigerant Compatibility: Designed to work with systems running R134a, R404A, and R290, ensuring versatile application across various cooling cycles.
- OEM Reliability: Ensures exact electrical matching to factory specifications, maintaining the balance of the single-phase refrigeration cycle.
Common Questions
When should I install a Danfoss 7701038 instead of a standard capacitor?
Use this kit when the compressor fails to start under load or when diagnosing "humming" issues in systems using thermostatic expansion valves (TXV) that don't allow pressures to equalize during the off-cycle.
Is this kit compatible with other compressor brands?
While functionally similar to other hard start devices, the 7701038 is specifically tuned for the capacitance requirements and relay trip-points of Danfoss hermetic units. Verification of microfarad (µF) ratings is required for non-Danfoss applications.
Does this kit help with low voltage issues?
Yes, by increasing the starting torque, the 7701038 allows the motor to turn over more effectively during voltage sags that would otherwise stall a standard permanent split capacitor (PSC) motor.
