Hydrotech HTO Series (Hardness • Taste • Odour)
Whole Home Water Refining System
Why choose between a water softener and a carbon filter when you can have both in one high-efficiency system? Our flagship Hydrotech HTO Series is a dual-tank refiner designed to strip away hardness minerals while simultaneously reducing up to 97% of chlorine, chloramines, and organic odours. Driven by the 89 Series 1” High-Flow valve.
- Dual-Tank Precision: Separate beds for Catalytic Carbon and High-Capacity Resin ensure maximum contact time and easier, more cost-effective maintenance.
- Refined Luxury: Eliminates the “pool water” smell of chlorine for softer skin, silkier hair, and better-tasting coffee and tea.
- Ultimate Efficiency: Up-Flow regeneration and precision brining use significantly less salt and water than traditional “all-in-one” cabinets.
- High-Flow 1” Porting: Engineered so even larger homes can maintain consistent water pressure, even during peak usage.


The Ultimate 2-in-1 Solution for Truly Refined Water
The Hydrotech HTO Series sets a higher standard for home water treatment. Most combination units mix carbon and resin in a single tank, which leads to media migration and expensive replacement costs. The HTO Series uses a unique two-tank design, keeping the media beds separate. This allows for superior chlorine removal and allows you to replace the carbon (which wears out faster) without having to replace your softening resin.
97% Chlorine & Odor Removal
Equipped with premium Catalytic Carbon, the HTO system is laboratory-certified to remove chlorine and organic matter from over 1,100,000 gallons of water. Say goodbye to dry, itchy skin and the harsh smell of municipal disinfectants.
Precision Up-Flow Regeneration
Unlike standard down-flow softeners that push hardness deeper into the resin bed, our Up-Flow technology drives minerals up and out. This “bottom-up” cleaning preserves the unused portion of the resin, drastically reducing salt consumption and extending the life of your system.
Professional Grade Features:
-
Large 4-Line Touch Pad: Clear, plain-English display with no confusing codes or symbols.
-
Soft Water Brine Refill: Keeps your brine tank clean and prevents “salt bridging” common in cheaper units.
-
Quick-Connect Design: Simplified installation with 1” elbow NPT connections and integrated turbine meters
-
Warranty: 7-Year Control Valve Warranty and a Lifetime Warranty on both fiberglass pressure tanks and the polyethylene salt tank.

The Hydrotech HTO Series is ideal for households on municipal water. It combines high-efficiency, high-flow water softening with whole home carbon filtration. Third-party certified to provide soft water while reducing bad taste and odour caused by chlorine and chloramines. Think of it as a combination of an efficient water softener and a giant Brita filter treating all water entering the home.
Included with the Hydrotech HTO Series are:
- Hydrotech’s premium 89 Series Upflow valve with 1″ porting.
- One cylinder containing cation water softening resin.
- A second tank containing a catalytic carbon media bed.
- A brine tank.
The benefits of soft water are many. They include:
- Silky shiny hair and soft supple skin…especially during our harsh dry winters.
- Use up to 75% less soaps and detergents.
- Prevent scale build-up on plumbing fixtures.
- Extend the life of your water-based appliances, like dishwashers, washing machines, coffee makers, and especially hot water tanks.
Once you experience soft water, it’ll be hard to believe you lived so long without it!
The benefits of soft water are many. They include:
- While chlorine is an integral part of the delivery of safe, potable water in a municipality, it isn’t the best for human health once it enters your home.
- Chlorine is quickly absorbed into the skin on contact and aspirated during showering. The Hydrotech HTO Series is IAPMO Certified for chlorine reduction. Its Aquafine catalytic carbon media bed reduces chlorine, chloramines, and chlorine by-products such as chloroform and other trihalomethanes (THMs).
- It will reduce chlorine by 97% for over 1.1 million US gallons.
- It will reduce bad tastes and odours.
- The removal of chlorine will protect the resin bed in the water softener cylinder. Chlorine will degrade softener media, shortening its lifespan.
- Your family’s hair and skin will appreciate the reduction in chlorine…especially during our harsh dry winters.
The Hydrotech HTO Series:
- Has only one valve and controller to control the operation of the complete system.
- Uses Upflow Regeneration which saves salt by preserving the unused portion of the softening bed from unnecessary depletion during regeneration.
- Uses Precise Brining which calculates the exact amount of brine required to regenerate, using up to 30% less salt.
- The Backwash Frequency Preset saves up to 2,000 gallons of water per year by skipping up to ten (10) backwash cycles on clean municipal water supply.
- Has a Soft Water Brine Tank Refill which keeps tank and injectors clean.
- Has an Emergency Regen functionality: if capacity goes below 3%, an automatic 20-minute recharge restores softening until the next regeneration.
The Hydrotech HTO Series carries a 7-year warranty on all its components. The media and brine tanks carry a lifetime warranty.
