With a single source for all brining components you are offered economy and dependability. As our customers will attest, we have the capability to customize systems to fit particular requirements for a given installation. Our bulk salt systems are manufactured to current ASTM standards, using USDA-approved resins and are conditioned to meet food grade sanitary guidelines. An exclusive Two (2)-Year Warranty backs our ISO 9001 quality standards and our 30+ years of experience.

The downflow brining principle ensures consistent brine saturation. As influent water rises, higher density brine sinks. Sludge from rock and solar salt is concentrated at the bottom of the system where it can be periodically removed.
Our tough, damage-resistant fiberglass reinforced plastic shell is constructed to withstand many years of brinemaking maintenance-free.
In many commercial brinemakers, inlet water is not distributed evenly. Eventually, this results in the formation of salt pillars in the tank, which can collapse and damage the vessel. This problem is eliminated in the by use of a schedule 80 PVC ring induction header around the inside circumference of the tank. The ring is installed at a three-foot height to spray water evenly around the base of the salt mass, resulting in the desirable plug or mass flow.
A collector on the bottom of the tank collects brine evenly over the entire surface area of the vessel by infiltration through 4″ ID slotted PVC pipe feeding a center mounted FRP plenum. It filters undissolved salt crystals and insolubles from effluent saturated brine. An outlet pipe draws brine from the plenum through a flanged and gussetted nozzle in the vessel wall. When fine vacuum granulated salt is used, the collectors are covered with a quartz rock filter bed to ensure that fine salt crystals do not pass through the slotted PVC pipe. Replacement of such a filter bed should never be necessary due to the insignificant insolubles content of vacuum salt.
A pneumatic loading and air venting system is designed for rapid loading, easy maintenance and minimum dust emissions. The 4″ ID fill pipe is fabricated from 304 stainless steel and mounted for center fill using a long radius turn to minimize particle attrition and dust. The pipe is fitted with an aluminum camlock coupling and cap that adapts to a P/D truck hose connection. A threaded nipple on the pipe may be fitted with a water hose to inject water during truck unloading to wet the conveyed salt, resulting in minimized dust emission.
Onveying air is exhausted through an 8″ gooseneck vent at the top of the vessel. A FRP extension mounted to the tank wall, with a salt dust bag at serviceable height, facilitates cleaning. Should the bag become plugged during filling, a 24″ weighted manway on the top will open to relieve pressure and prevent tank damage.
All of Nancrede’s Brine Systems are fitted with a 24” diameter side-mounted, leak-proof manway near the base for convenient clean-out access. This port is used for periodic sludge clean-outs, which are required when rock and solar salt are used. All collection and outlet internal piping is removable through the manway for cleaning or repair; however, removal of the internal piping is usually not necessary for a clean out.
Our unique brine level control system easily opens and closes a valve in the water inlet line to control liquid level.
The level control can be set for any desired liquid level. Normally, a “fully wet” mode of 8’ – 9’ is desirable for vacuum granulated or solar salt. For rock salt, a fully wet level may be used to reduce sludge accumulation and clean-out frequency, or a “semi-wet” level of 3’ – 4’ may be selected.
The digital level control is contained in a corrosion resistant waterproof box. The unit comes complete with a digital display revealing the brine solution level. An optional output signal for high-low level alarms capable of sending signals to a PLC (Programmable Logic Controller) is also available from Plas-Tanks.

Our tanks have received NSF 61 certification. Our systems are widely used in water softening, food processes and in the generation of sodium hypochlorite, which is used in water disinfection processes. The NSF standard 61 was developed in an effort to control the potentially adverse health effects of products added directly to water for its treatment, storage, and transmission.
Plasta-Therm® Thermal Retention System
Plasta-Therm®: Better from the bottom up
Plasta-Therm® Thermal Retention System eliminates the heating concerns of old-fashioned wrap around tape or heating plates. It drastically reduces operating costs with a system that is simple, efficient, and trouble-free.
Plasta-Therm® is available with any of the FRP tanks that we design and manufacture. It can be readily installed in the field or in existing FRP tanks.
What is Plasta-Therm®?
The Plasta-Therm® heating element consists of a fine-gauge, standard, nickel clad resistance wire encapsulated in braided “E” grade fiberglass. Plas-Tanks lays the Plasta-Therm® element near the bottom of the FRP tank and seals it into the structure with a 120-mil barrier.
The Plasta-Therm® element thus becomes an integral part of the tank itself. Protected by its own fiberglass braiding and by the fiberglass of the tank both above it and beneath it, the element is almost damage-proof.
Experience the Benefits of Plasta-Therm® vs. Wrap Around Tape
Plasta-Therm® is much more efficient than outside, wrap-around tape.
- Plasta-Therm® introduces heat at the bottom of the tank so that the heat can do what it does naturally: rise directly into the liquid above it. Wrap-around tape, on the other hand, has to transmit heat sideways through thick, insulating FRP walls. Hence Plasta-Therm® produces more usable heat per KWH of electricity than is possible with conventional outside tape.
The Plasta-Therm® element is controlled by a solid-state system that senses the temperature of the contents of the tank.
- The much more complicated capillary bulb thermostat used with wrap-around tape reacts to the temperature of the tape itself – not to the tank’s contents.
The Plasta-Therm® solid-state system maintains a temperature of ±3°F
- This is a degree of accuracy that is virtually impossible to achieve with conventional tape!
The Plasta-Therm® system eliminates the need for troublesome thermowells, capillary ports, and jumper wires.
Our Plasta-Therm® Thermal Retention System solves the problems that have long been considered necessary evils of outside heating tapes. More important, it provides the most accurate, efficient, reliable method of heating tanks ever developed.
