CoolGuard

The optimum cover for reducing water temperatures by up to 15%

What is a CoolGuard™ cover?

The innovative CoolGuard cover with available GeoBubble™ technology inhibits swimming pool algae, reflects the sun’s heat and saves money, time, water and energy usage, as well as being scientifically designed to last longer.

It is the combination of this products opaque light blue top surface and a black underside that gives the CoolGuard swimming pool cover the ability to provide a variety of benefits:

• Reduce water temperature by up to 15%
• GeoBubble technology
• Inhibit algae growth
• Reduce filtration/pump time by up to 50%
• Reduce chemical consumption by up to 70%
• Reduce energy consumption by over 50%
• Eliminate water evaporation by 98% +
• Save money
• Reduce debris contamination
• Can be used as a winter pool cover
• 6 year + expected lifespan
• Reduce the carbon footprint of your pool

CoolGuard swimming pool cover

Reduce water temperature by up to 15%

We know that the colour white reflects the sun’s heat in a very efficient way. Research and scientific tests have resulted in the development of an opaque reflective light blue colour that has similar heat reflecting characteristics.

On your pool the sun’s heat is reflected away from light blue colour top surface of the CoolGuard swimming pool cover and allows the water surface directly under the cover to stay cool and refreshing for you to enjoy. The CoolGuard material prevents the absorption of the sun’s energy and reduces water temperatures by up to 15%.

Reflect the sun's heat

GeoBubble technology

The CoolGuard material available with GeoBubble technology which through its unique and patented shape increases the expected life of the product by improving its endurance against the harsh swimming pool environment with attack from Ultra Violet light and chemicals.

Inhibit Algae Growth

A CoolGuard cover inhibits algae growth as the opaque reflective top surface and black underside will block light from entering the water, therefore stopping photosynthesis. The advantages of this to the pool owner are:

• Save money by using up to 60% less pool chemicals
• Reduce electricity usage and costs by cutting filtration/pump time by up to 50%
• Reduce filter blockages
• Lower the risk of eye, ear, skin and gut infections
• Avoid slippery surfaces
• Improve the aesthetics of the water
• Save money and time preparing a pool after the winter period

Winter cover inhibits algae growth

Research and tests

Even without chemical treatment, our experiments proved that the CoolGuard swimming pool cover inhibits algae growth.

The testing ran on two swimming pools for ten days, where one pool had a standard solar gain cover and the other an CoolGuard cover. Both pools had simulated use, with no chemical treatment and no filtration.

The pool with the standard solar gain cover soon went green due to algae growth, whereas the pool with the CoolGuard cover showed no algae growth.

This test was continued for a further two months and the pool with the CoolGuard cover still remained free of algae for the duration.

How can this save money?

A CoolGuard cover will save money by reducing water, heating, electricity and chemical costs. The CoolGuard swimming pool cover can pay for itself in less than a year.

Reduce Filtration/Pump Time by up to 50%

By inhibiting algae growth filtration time can be cut by up to 50% greatly reducing your electricity usage. Filtration will still be required to circulate the water and remove impurities from the pool, but calculated on regular pool use a 50% reduction is achievable. If the pool is used heavily more filtration time will be needed.

Reduce Chemical Consumption by up to 70%

Chemical usage can be reduced as the CoolGuard cover inhibits algae growth and eliminates water evaporation resulting in cost savings:

• Use of the CoolGuard swimming pool cover means algae growth will be inhibited by physical means rather than chemical means, this will result in the use of less chlorine.

• About 90% of chlorine consumed by outdoor pools is lost due to photolysis reaction which the cover also reduces.

• Additional cost savings will be made by using less pH plus/pH minus to correct any pH imbalance caused by algae.

• Chemical consumption will also be reduced through the elimination of evaporation of the water in which the chemicals are contained.

Research in collaboration with UK universities showed that by using a CoolGuard swimming pool cover on an average sized UK pool, 4m x 8m, up to 70% could be saved in chemical consumption, which equates to up to 11kg of chlorine!

Reduce Energy Consumption by over 50%

Reductions in the filtration time needed result in economic and environmental saving reducing energy consumption by up to 50%.

If the pool owner chooses to raise the temperature during colder periods pool heating costs can also be reduced as the CoolGuard cover will eliminate evaporation and greatly reduce heat radiation.

Heat retention tests carried out in collaboration with two UK Universities showed energy savings of over 50%. This applied to oil, gas, electric heater or heat pump usage. Where solar heating is used, it is possible to invest in up to half the amount of panels normally required for a pool without a cover.

By using a CoolGuard swimming pool cover on an average sized UK pool, 4m x 8m, that uses a modern heat pump, you could save up to 5000 kWh of electric every year!

Reduce Energy Costs

Eliminate Water Evaporation by 98% +

Using a swimming pool cover helps to save precious natural resources by reducing water consumption. By minimising water evaporation, by over 98%, you will also save considerably on your water costs.

Research carried out in collaboration with two UK Universities showed that in the UK an average sized pool of 4m x 8m the evaporation loss is approximately 32,000 litres of water per year. This could provide you with approximately 400 baths! This figure is reserved and will be considerably higher for hotter climates and windy conditions.

Eliminate water evaporation

Reduce Debris Contamination

Leaves, dirt, insects, bird droppings and other debris are not only unsightly in a swimming pool but also provide nutrients for algae and bacteria to feed on.

When the pool is covered these contaminants will be kept out of the water, greatly improving the quality and appearance of the water, plus helping to reduce chemical consumption.

The CoolGuard cover can be used all year and tests proved that the CoolGuard material has many benefits as a winter swimming pool cover.

From October 2008 through to April 2009 a swimming pool was covered with an CoolGuard cover plus a woven mesh debris cover, with no use of winter pool chemicals.

After the 6 month period the water was clear of algae. By not having to filter, backwash and vacuum the pool, you can save the hours of time normally spent preparing the pool, as well as saving money on chemicals and electricity usage.

Benefits to the environment as well as saving money

A CoolGuard cover will greatly reduce the carbon footprint of your pool by reducing the amount of energy needed to heat and filter your pool water. It also conserves water and, at the end of its life, all of our covers are 100% recyclable (Grade 4 LDPE recycling).

Warranty

The CoolGuard cover has a 6 year pro rata warranty. Please note that the length of the warranty may vary in some countries.
