Description
Henry Technologies S-7721 Vertical Suction Line Accumulator
The Henry Technologies S-7721 is a 2-1/8″ vertical suction line accumulator engineered to safeguard refrigeration and air conditioning compressors from the damaging effects of liquid refrigerant and oil slugging. By capturing and metering liquid back into the suction stream at a controlled rate, this accumulator extends compressor life and helps maintain peak system efficiency across a wide range of operating conditions.
Key Features
- 2-1/8″ suction line connection for compatibility with medium-to-large refrigeration and HVAC systems
- Vertical orientation for flexible installation in space-constrained equipment rooms and rooftop units
- Protects compressors against liquid slugging caused by refrigerant flood-back or system off-cycle migration
- Promotes oil return to the compressor, reducing the risk of oil starvation
- Durable steel construction built to withstand the demands of commercial and industrial refrigeration environments
- Henry Technologies quality — a trusted name in refrigeration system protection components
Applications
- Commercial refrigeration systems
- Air conditioning and heat pump systems
- Low-temperature and medium-temperature refrigeration circuits
- Systems prone to refrigerant flood-back or liquid migration during off cycles
Why Use a Suction Line Accumulator?
Liquid refrigerant entering a compressor’s suction port can cause catastrophic mechanical damage in seconds. A suction accumulator acts as a protective buffer — holding excess liquid and releasing it slowly as vapor, ensuring only dry refrigerant gas reaches the compressor. The Henry Technologies S-7721 is an essential component for any system where compressor longevity and reliability are a priority.
