cooling tower water treatment does more than just cool. It also acts as an air-scrubber for removing dust, pollen and pollution circulating through the system.....?
These people supported by our technical team of engineers, install and start-up the appropriate cooling tower water treatment systems. They also train personnel on-site on the use of the equipment.
VORTISAND® uses a tangential inlet to introduce water with a swirling action. The water centrifugal separators help to remove the suspended solids and significantly increase the effective filter surface within the tank. This creates a concave surface on the sand media and increases the total filtration surface area.
In a variety of applications such as evaporative cooling (side stream filtration), industrial water treatment (water reuse), processing, potable water and swimming pools.

Originator of the centrifugal sand filtration technology, Vortisand® filters have proven themselves for nearly three decades worldwide. Once installed, Vortisand® filters need no attention during backwash and rinse cycles. Vortisand® filters are widely used for various types of applications such as cooling water side stream filtration, water polishing, pre RO treatment, recreational and aquaculture applications.

VORTISAND® cooling tower filtration provides clean, clear water when used in conjunction with chemical treatment programs that chemical treatment alone cannot guarantee. Greater benefits result from very fine particle removal.

The VORTISAND® cooling tower filtration system is also used as a polishing filter or tertiary treatment for waste water plants to remove fine solids from water and meet the environmental regulations on suspended solids or other contaminants. Its compact size makes it very suitable in new installations or for adding to an existing system.
Vortisand®‚ is the pioneer in combining centrifugal water separators (Vortex effect) and sand filtration. In fact, it uses a tangential spin across the sand to keep dirt from building up in the unit. Using centrifugal force above the multi-layered media helps to remove the suspended solids and significantly increases the effective filter surface within the tank.
These people are professionally trained by our team of factory engineers. They receive the latest up to date knowledge on HVAC tower micron water filtration application, proper model selection and materials of construction, controls integration, serviceability, installation, and start-up. We guarantee a smooth transition from purchase to start-up.
VORTISAND® is a high performance automatic backwashable cooling tower sand filter that ingeniously combines centrifugal separation and sand filtration in the same vessel.VORTISAND® achieves very fine filtration (down to 0.45 micron) at high rate, using 80 to 90% less water for backwashing compared to the traditional cooling tower sand filter.
VORTISAND® provides a filtration 10 to 20 times finer than the traditional cooling tower sand filter. Continuous filtering removes suspended solids.
Our "A" Series is used for In-line applications to ensure a continuous or intermittent flow – the flow can be maintained during backwash operation. When one vessel is in backwash mode the remaining vessels ensure the selected flow. The VORTISAND® cooling water filter is available in a variety of materials and components depending on each application requirements. Sonitec manufactures customized systems based on your specifications.
We know that water is a valued vital resource and must be used with respect. Our vision is a perfect match with the latest green trends for water reuse. Sonitec contributes to a wise use of our water resource. “Leeding the way” to the best environmental practices by increasing industrial water filter systems performance.
Vortisand® filters used in a variety of applications such as stream-side filtration of cooling water, industrial water filtration systems, and drinking water treatment. In addition to offering a superior filtration, the Vortisand industrial water filtration systems benefits from an undeniable comparative advantage due to its low operating costs.
?The Vortisand® high-efficiency water filtration systems for the removal of suspended solids down to sub-micron range are easily installed and fully automatic. The very compact filters ensure a filtration that is 10 to 20 times finer than traditional sand filters. The performance of Vortisand® filters is due to a unique concept which ingeniously combines centrifugal separation and sand filtration.

Sonitec Inc. was founded in 1986 to manufacture and offer innovative technologies aimed at improving the quality of the water used in cooling and heating systems. Commercial, Industrial, Health Care and Educational Institutions had a sincere desire to improve energy efficiency, equipment performance and system integrity in their Heating, Cooling and Process water filtration systems.

Sonitec Inc. offers the Vortisand, centrifugal filtration system for various process water filtration applications. Vortisand is fully automated, compact and provides removal of solids as small as 0.45 micron. It also reduces backwashing frequency and amount of water used, the company says. The technology is applicable in pre-filtration in front of reverse osmosis equipment and more applications.
VORTISAND® provides a filtration that is 10 to 20 times finer than the traditional sand filters. Its high performance results from a unique concept that combines the centrifugal separator and sand filtration and this is what makes our filter the best available polishing solution to RO.
Our clients receive the highest degree of reliability and satisfaction with our cutting edge technologies. Sonitec has developed and marketed unique industrial water filters for polishing potable, process and wastewater.

VORTISAND® industrial water filters are available in a variety of materials and components depending on each application requirements. The standard model is suited for most conditions, and Sonitec manufactures customized systems based on customer's specifications.
Even if we became a reference to many, we always innovate and keep looking for ways to improve the quality of cooling water filtration and give our customer greater benefits and simple mode of operation.

Sonitec offers unique high-performance cooling water filtration solutions for customers worldwide. Our Service Options (Follow up Program, Long Term Service Contracts or Integrated Filtration Service) allow our customers to make the appropriate choice of equipment and to obtain cooling water filtration solutions that add value to their facilities.
In addition to cooling and heating applications, we developed a number of unique approaches for polishing water of specific applications such as:
Water polishing for RO pretreatment of reverse osmosis systems
Effluent treatment - removing suspended solids to meet discharge limits
Water reuse and zero discharge package
Water polishing for green buildings (rain water)
Recreational, Snow Making, Olympic Pools, Aquaculture

VORTISAND® is also very effective as RO pretreatment systems. The VORTISAND® filters have proven themselves for more than 35 years and are the result of many years of research and development.
The most suitable VORTISAND® cooling tower filtering system will be chosen according to the tonnage of the refrigeration system, the circulation flow and/or the volume of water in the system. Other parameters such as temperature and maximum inlet pressure will also be considered.
For cooling water filter applications (condenser and closed loop systems), the side stream installation handles large flow rates and cleans your cooling system automatically without interruption of the flow. Our proven technology will maximize your chiller performance and provide a very short energy payback.

Used for spray nozzle protection, VORTISAND® filters minimized municipal water consumption by switching to efficiently treated river water. The VORTISAND® cooling water filter gave opportunities to save on many other aspects.
In a variety of applications such as evaporative cooling (side stream filtration), industrial HVAC towers water filtration (water reuse), processing, potable water and swimming pools.
