Sentry® QCIII Quick Connect Systems

Entegris introduced their first patented Quick Connect System over 25 years ago and the system remains an industry standard for high-purity chemical dispense. Expanding on the proven performance and functionality of this quick connect system, the Sentry QCIII quick connect system is today’s safest and easiest method of connecting chemical containers with typical bulk chemical delivery systems.

 

This patented connection system comprises a key coded dispense head (DH3) and drum insert (DI3) that self align. Simply rotating the retaining ring pulls the DH3 and DI3 together so no visual line of site is required to make the connection – simplifying the assembly process significantly.

 

The Sentry QCIII quick connect system is designed for use with FluoroPure® chemical containers including HDPE transport drums, PFA composite drums, pressure vessels and intermediate bulk containers.

 

  • The main chemical dispense line utilizes Flaretek® sealing technology, providing a leak-free, secure connection.
  • The system’s four ports enable recirculation and dispense operations in one connection.
  • The optimized dispense head flow path allows chemicals to dispense at 1.5x the flow rate of standard quick connect.

O-ring Free Main Dispense Seal

The main chemical dispense line utilizes Entegris’ industry leading Flaretek® sealing technology, which provides a leak-free, secure connection without o-rings. This sealing technology decreases your cost of ownership by eliminating the need for o-ring replacement and maintenance while minimizing downtime.

Key Codes

Our patented quick connect system is key coded to ensure against unsafe chemical mixing while guaranteeing dedicated clean service. One connection provides dispensing, venting and level detection/connection verification.

 

 

Dispense Port Water Flow

Recirculation and Dispense in One Designing four ports into the system enables recirculation and dispense operations in one connection. This eliminates the need for an independent recirculation dispense head and drum insert. The single dispense head connection assembles faster, requires less labor, reduces maintenance and lowers your costs.

1. The 3⁄4" fill and dispense port allows higher flow in either filling or dispense applications

2. The 1⁄2" vent port allows proper ventilation during chemical dispense operations

3. The 1⁄4" connection verification port ensures proper DH3/DI3 engagement prior to initial dispense operations if OEM equipment is equipped with this feature

4. Optional 3⁄4" recirculation port allows chemical recirculation; an optional diffuser, which reduces chemical agitation and foaming typical with chemicals containing surfactants

Higher Flow Rates Entegris’ innovative dispense head optimizes the flow path to allow chemical dispense at 1.5x the flow rate of standard quick connect systems. This larger flow volume increases the overall capacity of your bulk chemical dispense system, reducing recirculation time and increasing process efficiency.
