pulsar feeder systems
Pulsar® Feeder Systems

For a remarkable difference in pool water clarity, color and sparkle.
Our advanced feeders and controllers combined with our Pulsar® Briquettes provide systems that give you the power to accurately maintain clean, clear and balanced pool water.

It’s an easy to use sanitation method that chlorinates, treats organics, controls metals, boosts hardness and shock treats all in one simple process.

  • PLC based
  • Touchscreen interface
  • USB port for updating software
  • Controls booster pump for optimal performance and efficiency
  • Calculates individual pool/spa LSI

The new highly efficient Pulsar® 45, 140 and 500 system’s design improve reliability compared to previous Pulsar® models. These systems:

  • Feature a spray technology that enhances your pool’s filtration system
    • Water from the pool enters the Pulsar® Chlorinator via the inletport. The spray manifold then distributes the water onto the briquette grid creating a chlorinated solution. The chlorinated solution falls into the discharge tank and is discharged into the pool recirculation system by the evacuation system. Water flow in the unit is designed to remove residue from the chlorinator base
  • Offer a more reliable dosing method - a smaller reservoir with an updated discharge valve arm allows for more accurate dosing
  • Are easy to operate & maintain - PLC driven control box with touchscreen controls
  • Have automated cleaning features - the automatic wash down nozzles and the well agitator nozzle spray after the unit is done feeding to clean the inside of the Pulsar® feeders, whis is controlled by the Pulsar® Control Box logic
  • Have an improved carbon footprint - booster pump control option reduces energy consumption
  • Feature a downstream venturi injection
  • Use with Pulsar® Briquettes

Pulsar® 45 System - For pools up to 565,000Ɩ

Pulsar® 140 System - For pools up to 2,250,000Ɩ

Pulsar® 500 System - For pools up to 6,000,000Ɩ

Pulsar CRS feeder system

Pulsar CRS™ Feeder System

Pulsar CRS™ technology achieves up to 99% Crypto removal. Adding Pulsar CRS™ technology functionality to your filtration system not only gives the facility crypto protection, it also acts as a clarifier. It not only increases the filter’s capacity to capture crypto oocysts, but it also catches other dirt and debris that could make the pool cloudy.

  • Improves efficacy of UV Systems
  • Improves water clarity and safety
  • Reduces fouling of controller probes
  • Biodegradable
  • Available in 18 and 200l kits
  • Traps microorganisms such as Cryptosporidium in stable flocculants that are carried to the filter media and then filtered out
  • Works on all types of filters, but DE, zeolite and cartridges have better filter capabilities than sand and are therefore more likely to have increased filter pressure from initial use
  • Noticeable pressure increases have not been observed after the first backwash

The Pulsar CRS™ feeder system should be used in conjunction with a proper sanitizer as another layer of protection in a total risk management program.

Sanikit Tablet Feeder System
Lonza Sanikit™ Tablet Feeder System

The Lonza Sanikit™ systems are reliable and are easy to install and operate. With the advantage that no electricity is required with these systems, they are cost-effective and require little maintenance.  

How This Feeder Works
With a gravity fed or pressurized (max 80 PSI) water supply about ¼ of the water to be treated flows through a mixing chamber dissolving HTH® Disinfecting Tablets. A concentrated chlorine solution is created and then remixed with the remaining ¾ of water. This freshly treated water needs to flow into a storage tank to ensure proper contact time.

  • Treatment for system flows of up to ~1M/day
  • Low to mid-sized potable water networks serving between 500 and 5000 persons depending on local conditions and quality of the water to be treated
  • A range of model sizes are available depending on requirements
  • No electricity required
  • Proportional feed rate (function of the flow rate)
  • Intermittent or continuous treatment
  • To be used in conjunction with HTH® Disinfecting Tablets
