Commercial & Industrial Water Softeners
Skid-mounted commercial and industrial water softener systems engineered, built and factory-tested by Robert B. Hill Co. Single-tank to multi-tank parallel configurations from 18 to 700+ GPM for manufacturing, healthcare, food and beverage, hospitality and more.
Commercial & Industrial Water Softener Systems by Flow Rate
Choosing the right commercial or industrial water softener means matching your facility’s peak flow rate (GPM) and daily capacity to the right system, so you avoid pressure drops and wasted salt. Every system below can be built as a skid-mounted water softener, pre-piped and factory-tested before it ships. Browse by flow rate, then compare full specs, model numbers and data sheets on each product page.

Skid-Mounted Water Softeners
A skid-mounted water softener ships as one complete assembly: resin tanks, valves, piping, flowmeters and controls mounted and pre-plumbed on a steel skid, then pressure- and cycle-tested at our facility before it leaves. On site, your contractor or our technicians set the skid, connect inlet, outlet, drain and power, and the system is ready to run.
- Faster installation: no field assembly of tanks, valves and piping
- Less downtime: plumb-and-play connection to inlet, outlet, drain and power
- Factory-tested for pressure and regeneration cycles before shipment
- Compact footprint sized for tight mechanical rooms
- Industrial options: PLC/HMI controls, NEMA 4/4X panels, ASME code vessels and online hardness analyzers
Every Hill commercial and industrial water softener can be built skid-mounted, from compact duplex skids to multi-tank HICAP-XL industrial water softener arrays. See a custom skid-built water softening system we delivered, or read more about the benefits of skid-mounted water treatment systems.

What to Expect When You Work With Hill
Rest assured that you’re working with water softener experts who value transparency. Here’s how it works:
Consultation & Sizing
We start by learning your business inside and out, from water quality reports to daily usage patterns and space constraints.
Our team uses this data to design a system that delivers the right flow rates, regeneration schedule, and efficiency for your specific application.
You’ll get a clear proposal, including system specs, cost, and installation timeline, so there are no surprises.
Commercial Water Softener Installation
Every system is skid-mounted, pre-piped, pre-wired, and factory-tested before it ships.
That means faster installation, less disruption, and minimal downtime for your operation.
Our technicians coordinate directly with your team or contractor to ensure the system is set up, tested, and ready to perform from day one.
Maintenance, Support & Salt Delivery
We stand behind our systems long after installation.
Our maintenance plans include resin checks, valve calibration, and regeneration optimization to keep performance at peak levels.
Need help? Our technical support team is available by phone, chat, or on-site visit. And with scheduled water softener salt delivery for our Minnesota clients, you’ll never have to worry about running low on brine again.

Commercial & Industrial Water Softener FAQs
What is a skid-mounted water softener?
Skid-mounted water softeners arrive pre-assembled, pre-piped, and factory-tested on a sturdy steel frame (skid), allowing for fast installation and minimal downtime. Just connect power and water, and the system is ready to go.
What is the difference between a commercial and an industrial water softener?
Mostly scale and duty. A commercial water softener typically serves restaurants, hotels, car washes, laundromats and multifamily buildings at roughly 20–120 GPM. An industrial water softener serves boiler feed, process water and cooling systems at 150 GPM and up, with larger resin beds, multi-tank parallel arrays, PLC controls and options like ASME code vessels and online hardness analyzers. See the HICAP-XL Series industrial water softener for an example.
How do commercial and industrial water softeners work?
Water softeners for commercial use utilize ion exchange resin to swap hardness-causing minerals (calcium, magnesium, iron) with sodium ions, producing soft water that protects plumbing, scales, boilers, and process lines. Learn how commercial water softeners work here.
How do I know what size system I need?
Sizing depends on water hardness (grains per gallon) and your daily usage (gallons per day). Multiply these to determine your grain requirement, then choose a softener that handles that capacity before regeneration. Learn how to size a commercial water softener here.
What are the main benefits of installing a commercial or industrial water softener?
Soft water extends equipment life by preventing scale buildup, improves boiler and cooling tower efficiency, reduces detergent, energy, and maintenance costs, and enhances operational reliability and safety in demanding environments
What upkeep and maintenance can I expect?
Regular tasks include monitoring and refilling salt levels for regeneration, inspecting valves and swapping worn seals and pistons every 1–2 years, periodic resin cleaning and system inspections. Optional vendor maintenance plans can reduce your workload.
Are there environmental concerns or regulations?
Yes. Salt-based systems generate brine discharge that may require permitting or compliance with local wastewater regulations. Efficient systems and proper planning can help minimize environmental impact.
How do I choose between timer-based and meter-based systems?
Timer-initiated systems regenerate on a fixed schedule, which is simpler but can waste salt and water. Meter-initiated systems regenerate based on actual water usage, offering higher efficiency and cost savings.
Does Hill install home water softeners?
No. Robert B. Hill Co. focuses exclusively on commercial and industrial water softening systems for businesses. While we don’t install home water softeners, we do supply wholesale water treatment equipment to qualified businesses and contractors. Become a dealer.
