Recirculation / Neutralization Systems (RNS) from BHS control, filter, and recirculate water used for cleaning industrial batteries. This dramatically reduces volumes of contaminated wastewater, cutting down on disposal fees.

Recirculation / Neutralization Systems (RNS) from BHS control, filter, and recirculate water used for cleaning industrial batteries. This process cuts down on disposal fees by greatly reducing the output of contaminated wastewater.

Each model of RNS is equipped with a spray wand (spray wand in not included when combined with a BHS Battery Wash Cabinet) connected to a 10-foot (3 meter) hose. A 120 V / 1 PH external sump pump operates automatically to return battery wash water from the wash cabinet back to the RNS. The result is a steady source of battery wash water that complies with environmental regulations and reduces overhead.

In combination with a BHS Battery Wash Cabinet, the RNS creates a closed-loop system that contains and controls the water used for cleaning industrial batteries.

Water used to wash forklift batteries becomes contaminated with acidic residue, lead particles, and other potentially harmful substances. The EPA places strict limits on disposal of wastewater left over after battery washes.

Recirculation / Neutralization Systems from BHS allow you to reuse your wastewater rather than paying for compliant disposal or, worse, making a mistake while disposing of it in-house. Every model of RNS is designed to feed directly into Battery Wash Cabinets from BHS, creating a closed-loop system that can complete multiple washes with the same volume of water.

Contaminated water passes through a special filter which removes particles down to 5 microns. Filters are inexpensive and easy to replace when they fill up. Next, the system neutralizes the pH level of the water, removing the acidic content.

The RNS-4-SS provides another level of cleaning with an ozone water-purification system.

RNS-1

The RNS-1 comes standard with a 125 gallon (473 L) polyethylene tank. Voltages are available in 120 V & 240 V / 1 ph or 240 V & 480 V / 3 ph / 60 Hz. This machine is fitted with fork pockets for easily relocating the unit. A handheld pH meter allows staff to monitor pH levels throughout the neutralization process.

RNS-3-SS

The RNS-3-SS comes standard with a 200 gallon (757 L) integral tank and utilizes 120 V / 1 ph / 60 Hz power. A hand-held pH meter allows staff to monitor pH levels as they return to a safe state. The RNS-3-SS features an on-demand, automatic start system. An auto-shutoff for filter service or low water level makes maintaining the system simple and easy.

RNS-4-SS

The RNS-4-SS comes standard with a 200 gallon (757 L) integral tank and utilizes 120 V / 1 ph / 60 Hz power. An automatic pH monitoring system is what makes this model the most popular in the RNS family. The system automatically shuts down for unsafe pH range while warning lights alert the operator, who can inject neutralizer with the push of a button to bring the pH back in balance.

The RNS-4-SS features an on-demand, automatic start system. An auto-shutoff for unsafe pH range, filter service, or low water level makes maintaining the system simple and easy. This ecologically friendly system also boasts a built-in ozone purification system.
