Hydro Introduces New AccuMini Dispenser

DOWNERS GROVE, Ill., June 28, 2023 /PRNewswire/ – Hydro, part of PSG and Dover (NYSE: DOV), today announced the release of its new AccuMini™ dispenser. The AccuMini, available in low-flow (LF) and high-flow (HF) models, is designed to meet the needs of space-conscious and environmentally focused facility owners.

Building off the design and multi-market success of Hydro’s highly regarded AccuMax® dispenser, the AccuMini offers similar operational benefits but in a smaller size. At only 4.3” wide by 8.0” long, the AccuMini is among the smallest dispensers currently available on the market. An optional plug add-on narrows it to 3.9” wide, making it the slimmest of all top-choice dispenser models. The size reduction makes it ideal for use in a wide range of applications and reduces its environmental footprint, given the 46% less material required for production.

Additionally, the AccuMini allows the use of Hydro’s new Swivel AirGap™ eductor, which employs a 1-inch gap of air between the water source and the chemical inlet to provide American Society of Sanitary Engineering (ASSE) 1055B-approved backflow protection without the need for additional hardware. The Swivel AirGap’s construction is made more environmentally sustainable by requiring up to 42% less construction material with up to 40% reduced space. Powered by Hydro’s patented AccuPro Pressure Regulation Technology, the AccuMini delivers industry-leading accuracy of up to 95% dilution control in both high- and low-water-pressure applications.

The AccuMini also offers the following operational benefits to the user:

  • Ability to daisy chain multiple units together with no required additional tools or accessories. This saves installation time and space and enables expansion of the number of chemistries that can be used as they are needed
  • A one-touch button lock that is more ergonomic and intuitive to operate than the buttons found on competitive models
  • Use of O-ring seals, which allow water-inlet swaps with leak-free seal-tight performance
  • A simple three component design – cover, button and water-valve manifold – all of which can be removed without tools
  • Two flow-rate configurations: 1 gallon per minute (GPM) and 3.5 GPM
