Hoshizaki H9320-52 Twin Water Filtration System - 4 GPM, 42,000 Gallon Capacity Description

Hoshizaki H9320-52 Twin Water Filtration System - 4 GPM, 42,000 Gallon Capacity Commercial Description

Hoshizaki H9320-52 Twin Water Filtration System - 4 GPM Protection for High-Volume Ice Equipment

The Hoshizaki H9320-52 twin water filtration system supplies treated water to compatible high-volume commercial ice equipment at up to 4 gallons per minute. Its twin-cartridge design has a rated service capacity of 42,000 gallons, giving operators a practical way to address sediment, chlorine taste and odor, and fine particles before water reaches the ice machine.

The system uses two Hoshizaki 4HC-H replacement cartridges and carries a nominal 1-micron filtration rating. Hoshizaki's performance information lists an average chlorine reduction of 97.3 percent, Class I particulate performance under NSF/ANSI Standard 42, and 95.6 percent reduction of particles measuring one micron or larger. Cleaner incoming water can improve beverage taste and ice appearance while helping protect water-contact components from suspended debris.

A stainless steel head and mounting manifold support commercial installation. The twin assembly is intended for selected high-capacity Hoshizaki KM cubers and compatible equipment, including applications in the approximately 900- to 1,301-lb/day class identified by Hoshizaki. It is not the manufacturer's recommended choice for flaker applications, so compatibility should always be checked against the exact equipment model before purchase.

Filter life depends heavily on inlet-water quality and usage. In locations with visible sediment or unusually dirty water, Hoshizaki recommends adding the E-20 prefilter to twin and triple systems to help extend cartridge life. Replacement should follow rated capacity, flow reduction, water-quality changes, or the maintenance interval required by the installation—whichever occurs first.
