7 factors that determine the cost of commercial UV water sterilizers

Table of Contents

Commercial UV disinfection system is widely used in different areas, such as:

  • Whole house drinking water
  • Industrial water purification
  • Sewage water treatment, etc

All related water filtration system.

From small UV water sterilizers to big UV sterilization for the civil facilities in the water supply system.

To understand the cost of UV water purifiers, it is necessary to break down the product structure, deconstruct it, and analyze and compare the cost of each item.

Research has found that these seven factors may affect the cost of commercial UV water disinfection systems.

1. The size of the UV water sterilizer

The size of a commercial UV water filter affects the cost because it is proportional to the capacity of the UV product.

The larger the capacity, the higher the price.

The flow rate of UV disinfection depends on the UV housing size, and the inlet and outlet diameter, and UV light power, etc.

For example, 1GPM UV chamber diameter is 51mm with 1/4 threads and 6GPM UV chamber diameter is 63mm with 1/2″ threads, but 24GPM UV chamber diameter is 114mm with 1″ or 2″ threads or flanges.

Even for 100T/H, the stainless steel chamber diameter is 273mm with DN150 flanges, needs 12pcs 120W UV lamps and the cost is also several times of 1GPM UV sterilizer.

2. The type of UV light used

The quality of a germicidal ultraviolet lamp is very important, and the intensity determines how much it costs.

The more UV rays there are in ultraviolet light to kill bacteria or viruses on your item, the better protection you get from germs.

Different brands, the cost is also very different, big brands obviously more expensive than the normal ones.

The intensity of ultraviolet radiation is the key to UV lamp quality, the more stable the better.

Also, the UV visible light is from phosphor powder, the cost of the powder is also different as an imported big brand or local.

Normally Chinese high-quality UV lamp can last 8000 hours for stable UV intensity, but the price is cheaper than big brands.

3. Whether or not a pre-filter is included

If the product with a pre-filter, then this will become a complete UV water disinfection system, the cost will be higher.

If there is no pre-filter, then it is simply the cost of the UV sterilizer.

Many systems are combined with UV systems and water purification systems.

And most UV manufacturers normally make a simple UV system like pre-filtration with a UV sterilizer together.

So the water inlet through a sediment filter, then maybe to an active carbon filter, then go to UV sterilizer, or maybe from sediment filter go to UV sterilizer directly.

It depends on customers’ requirements and budgets.

4. How many gallons per minute (GPM) UV water purifiers can process

The bigger the treating water flow rate(GPM), the cost more expensive.

In the commercial applications market, it depends on the common germicidal flow rate preferences, such as 12GPM and 24GPM in the US, and 15GPM and 30GPM in Europe.

However, sewage ultraviolet sterilization system normally needs 100T/H treated flow rate.

5. The power of the UV light source

The higher of UV C light power, the cost certainly higher.

The UV light power decides the UV chamber size, the quartz sleeve size, and the UV ballast power as well.

6. UV Ballast function and quality

The UV Ballast quality good or bad is an important thing for your purchasement. Quality is the first!

Anyway, the ballast cost also can determine from the following other factors.

  1. Whether with alarm or not
  2. Whether with timer digital display or not,
  3. Whether with a control system
  4. If with remote monitoring
  5. If with UV intensity monitoring
  6. If with integrated system management,
  7. If with LCD display

All the above functions can change the UV ballast cost. 

7. What kind of warranty is offered by the UV manufacturers

When buying UV systems, you need to check if there is a warranty and how long it is.

With this information, you can better determine if the product is of good quality and reliable.

If it is a product without a warranty, then it will definitely affect the cost of the product.

The more expensive ones are usually made of better materials and are more reliable.

However, you should also be careful when buying items at very low prices because they may be lower-quality products.
