Wysiwash® Jacketed Caplets are loaded into a wand, then water from the hose flows through to provide a chlorinated solution that kills bacteria, destroys organic contaminants and controls algae.

• Active ingredient: 68% Calcium hypochlorite
• Dissolve through hose-connect application

Why should I change to hth?

Changing to hth is easy. Many pools in both soft and hard water areas, have successfully changed to hth for the unique benefits and savings that it brings. With a range of products & pack sizes to suit all pools and any plant room situation, hth is widely used in the smallest spa pool and water play feature right up to 50m pools and large lidos.

These figures are based on 1kw/h of gas costing £0.06 and water costs of £1.00 /m³ to purchase and £2.00 /m³ sewerage costs. Assumptions have to be made on the efficiency of the boiler - for an average gas fired boiler within a facility it takes around 1.2 kw/h to heat up 1m³ of water by 1^oC, with the average temperature of incoming mains water 10^oC.

It's easy to change - see what some of our customers say...

Usually a conversion can be achieved for less than the cost of a new bulk storage hypochlorite tank and wherever possible, existing equipment is utilised.

hth Dosing - Pump and Tank system

Figs 1 & 2 - A basic pump and tank system - similar to that used for dosing sodium hypochlorite.

Site surveys by Lonza personnel identify existing equipment that can be utilised to dose hth. Wherever possible existing pumps are redeployed, for example, using the main pool dosing pump on a small pool if appropriate. However the tank itself is usually increased in size, resulting in less frequent recharging. If briquettes are to be used, a suspension net is required which Lonza can provide free of charge, see Fig 2.

Pools remain fully operational during the installation of any type of preferred dosing system.

hth Dosing - Dedicated Feeders

Dedicated feeders are ideal for sites which require minimal operator involvement, as they offer both safety and convenient dosing. There are several feeders which are capable of dosing two pools independently - again bringing down the cost of conversion.

Lonza Technical Services offer a free and no obligation site survey where we will identify your specific requirements and advise on the feeders most appropriate for your site from the Lonza Easiflo^® feeder range

New highly efficient design improves reliability and decreases required maintenance.

• Features a unique 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.
• More reliable dosing method - a smaller reservoir with an updated discharge valve arm allows for more accurate dosing
• Easy to operate & maintain - PLC driven control box with touchscreen controls
• 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. This is controlled by the Pulsar® Control Box logic.
• Improved carbon footprint - booster pump control option reduces energy consumption
• Downstream Venturi injection
• Use with Pulsar® Plus Briquettes
