Selection and purchase of resin Softener

Regardless of their capacity, resin softeners have automatic and semi-automatic types. Stay with us in the future to provide you with more technical information about the types of resin softeners and how to estimate their capacity and choose them.

Review, Selection, and Purchase of Resin Softener

Water softeners are used to remove and destroy magnesium and calcium ions or water salts, and resin softeners are responsible for removing suspended mineral compounds and water-soluble salts in the building's heating and cooling systems in the best way. The resin hardener has a very resistant metal cylindrical body or an FRP body, and its internal design is made in such a way that there is a bed of silica and resin in it.

It is necessary to remove the hardness or the salts in the water because the salts in the water when the water is heated or even cooled in the equipment and installation systems in the form of deposits on the heat exchange surfaces such as the inner surfaces of the tubes and the combustion chamber of the central heating boilers. Coils of coil sources, heat exchange surfaces in heat exchangers, condensers and evaporators of chillers, coils of fan coils, air conditioners, etc. are stuck and reduce heat transfer and as a result, reduce heat exchange and system efficiency.

Types of Resin Softeners According to Body Type

• Fiberglass Softener: Its body is made of fiberglass and polyethylene, the body color of these resin Softeners is often white or blue.
  
• Metal Softener: its body is made of steel or galvanized, metal resin Softener has a higher capacity than fiberglass Softener and is used for larger and industrial buildings.

Types of resin Softeners in terms of how the multi-way valve works

• Fully automatic water softener: Reviving and cleaning the resin (backwash) is one of the most important operations that is performed after removing water hardness in water softeners. Performing this operation in some equipment and detecting its time is done automatically without the intervention of a human operator. These devices are called fully automatic softeners.
  
• Semi-automatic softener: In the semi-automatic softener, due to the use of a manual valve, the process of detecting the time of washing and changing the resin is not done automatically, and a skilled human operator is needed to do this.

Types of resin softeners in terms of structure and shape

• Single tank: In the structure of this device, only one source is considered, where hard water enters it and after passing through the resin layers, it turns into soft water and finally leaves the tank.
• Two tanks: In this type of resin softener, two tanks are considered, so that in the step of replacing or washing the resin layers, the replacement tank performs the water-softening process.

Buy semi-automatic and automatic resin softeners

To calculate the capacity and choose the required resin softener, after determining the amount of water consumed in the complete cooling and heating cycle of the project and measuring the amount of water hardness in the project location (using special kits available in the market or its special tools), you can use From the formula given below, the capacity of resin softener was calculated with sufficient accuracy.

Also note that the volume of resin, the dimensions of the softener (such as diameter and height), and the material of the body are the main characteristics of a resin softener. Resin hardener manufacturers usually provide general specifications including service water flow rate, regeneration flow rate, and quick washing flow rate, based on which the volume of resin can be calculated.

In order to choose and buy a semi-automatic and automatic resin softener, you must first determine its capacity and type. On the site of Damatajhiz HVAC's specialized collection, the technical information of dozens of models of resin softeners, from reputable brands with original warranties, has been presented in order for you to enjoy the good feeling of an optimal and smart purchase.

Semi-automatic and automatic resin softener price

The price of semi-automatic and automatic resin softeners is different according to the variety of models and capacity, body material, and brands available in the market, it should be noted that the prices offered in the Damatajhiz HVAC collection are up-to-date and the discounts desired by consumers in These prices are included. You can check the different types of resin softeners at the best price for the best choice by visiting the Damatajhiz HVAC website.

Advantages of resin softener

1. Reducing the harmful effects of water hardness on the health of the body and the occurrence of problems such as kidney and bladder stones
2. Save money and energy
3. Extends the useful life of equipment and appliances such as pipes and appliances
4. Reducing the possibility of precipitation of calcium and magnesium sulfate in water pipes

How resin softeners work

In resin softeners, water softening is done using an ion exchange process. As ion exchange resins absorb hard water ions and instead replace sodium ions, sodium ions are stable in water and do not precipitate. For this reason, water containing sodium ions is called soft water. Of course, it should be noted that the choice of resin depends on the hardness and type of water hardness.

Resin softener loses its ion exchange power after a while. When the resins lose their ion exchange power and do not function properly, they should be washed with a 10% salt or sodium chloride solution to restore their ion exchange power. Before the salt water passes over the resin, the resin is first rinsed so that the salt does not enter the water of the central heating system because salt is highly corrosive and damages the equipment of the facility system.

Important points for choosing resin softener

• Inlet water hardness in PPM
• The inlet water flow rate makes it hard to hold the resin
• Resin type and capacity
• The time taken for the regeneration and washing cycle in this device

Constituent components of resin softener

1. Resin hardening tank:
   The tank and the source considered for the placement of the resin layers and the entry of water to pass through these layers are the most important components of the hardener. A very important point in the hardening tank is its very high resistance to impact and corrosion
2. Resin softening nozzle:
   After removing the calcium and magnesium in the water and producing it into soft water, the filtered water is collected by the nozzle.
3. Softening resin:
   Resin grains are other important components in water hardness equipment, which are placed in the lowest level of the tank in cationic and anionic types. With a lot of use of resin hardeners and the presence of salts such as copper and manganese in water, it has caused a lot of damage to the efficiency of the resin over time, and for this reason, it is necessary to replace the resin layers.
4. Multi-way valve with resin hardness:
   In semi-automatic and fully automatic softeners, the process of reverse washing or backwashing of resin layers takes place. This operation is done by setting the solenoid valve mode, which is done automatically in automatic hardeners, and the human operator manually adjusts the solenoid valve.
5. Resin hardening salt tank:
   In order to revive the resin layers and increase their efficiency after contact with manganese and iron in the water, a small tank is considered next to the main resin softener tank.
6. drain pipe
7. Silica substrate
8. Viewing window

The following formula can be used to calculate the resin softening capacity

Calculation of required resin softener capacity (Grain) = Water crossing field from the softener (GPM) * 60 * 24 * The hardness of the water entering the softener / 17.1

In order to calculate the required resin hardness capacity, after determining the amount of water consumed in the cooling and heating cycle of the project and measuring the water hardness of the project site (using special kits available in the market), the resin hardness capacity can be calculated using the above formula. calculated with sufficient accuracy.

Application of resin softener

1. Prevention of water transfer pipe clogging.
2. Used for softening boiler and heat exchanger water.
3. Preventing scale buildup on heat exchange surfaces in heating, HVAC, and industrial systems.
4. Softening water used in paint and dyeing industries.
5. Boilers, reactors, and makeup water.
6. Used in dry cleaners and large restaurants.
7. Applied in reverse osmosis processes or deionization systems.
