Description
The DiversiTech DST-6 Hard Start Kit with Torque Plus technology is engineered to deliver up to 500% additional starting torque to single-phase air conditioning and refrigeration compressors. By dramatically reducing the time and amperage required to bring a compressor up to operating speed, the DST-6 helps protect the compressor from the stress of hard starts — one of the leading causes of premature compressor failure.
Why Use a Hard Start Kit?
Compressors that struggle to start — especially under high head pressure, low voltage conditions, or after short-cycling — draw excessive current and generate damaging heat. The DST-6 addresses these issues by providing an instantaneous burst of starting torque, getting the compressor spinning quickly and efficiently every time.
Key Features
- Torque Plus technology delivers up to 500% starting torque boost
- Reduces compressor start-up amperage draw
- Helps extend compressor service life by minimizing start-up stress
- Ideal for systems experiencing hard starts, slow starts, or tripped breakers
- Compatible with single-phase residential and light commercial AC and refrigeration compressors
- Simple two-wire installation — connects in parallel with the existing run capacitor
- Compact design fits easily within most equipment cabinets
- Solid-state design with no moving parts for long-term reliability
Applications
- Residential central air conditioning systems
- Heat pump compressors
- Light commercial refrigeration units
- Systems operating on low or unstable voltage
- Older compressors showing signs of hard-start issues
