The Benchmark is Branson’s flagship aqueous ultrasonic cleaning system, a culmination of over 60 years of experience. So much more than just a piece of equipment, the Benchmark is a process solution customized to your precision cleaning needs.

Equipment Applications Accessories Literature and Customer Info Theory

Benchmark Series precision modular cleaning systems incorporate design features and design standards by which all other systems are judged. From state-of-the-art ultrasonic generators to the latest in process management, the Benchmark Series will meet your needs. They are designed from an end-user point of view. Quality, reliability, process flexibility, and serviceability are all designed in.

Virtually any combination of cleaning, rinsing, passivation and drying modules are available for a custom workflow.  Individual modules are selected to form a continuous cleaning process tailored to the specific needs of your applications — not pre-configured, which may hinder your ability to properly clean delicate components, or expand as your cleaning requirements change.

Benchmark Hot-Air Dryer

Air is heated to above 200º F, which enables it to absorb moisture from the parts. Room air is filtered, heated, and circulated through the drying chamber. A significant advantage of Branson's recirculated hot air dryer is that the energy used to elevate the temperature is reused, minimizing overall energy consumption.

Key Features and Benefits:

  • Available in three sizes
  • Temperature range ambient to 250º F +/-3º F
  • High response NiChrome heaters
  • A programmable logic controller (PLC) controls all functions
  • Recirculating hot air for efficiency
  • All stainless steel construction for long life
  • High efficiency, high flow blowers for fast drying
  • Temperature alarm with automatic shut-off
  • Non-contaminating heaters
  • Low loss duct design for improved efficiency
  • HEPA filtration for precision drying applications 99.97% effective at 0.3 micron particles
  • Linear actuated power cover with releasable hinge for operator safety
