Outgassed Oxygen Collector Gets Redesign
The newly designed SOLAR-RIPP® air
separator collects oxygen that is outgassed during operation as well as residual air that remains in the solar energy system after startup, especially in the upper inside ‘pockets’ of the ribbed solar pipes. The air intake volume is just under 500 cubic centimetres, in other words half a litre. Delivery includes a SOLAR- RIPP®
coupling bush which allows the component to be connected directly to the original 50mm outgoing line (hot water outflow) or after the 90° or 180° bend, ideally at the highest point in the system. The company were unable to achieve satisfying results with the products currently on the market for the pool industry – either additional air was drawn into the system or the parts leaked water, which inspired them to design a better solution. Even supposedly automatic systems failed
to meet their quality standards under strongly fluctuating pressure and temperature conditions. That’s not surprising when you consider that some absorber systems, for instance ground assemblies, are located on a slope 1 metre under the pool, while other builders install their systems on a tiled house roof several metres above the pool.
In order to ensure that solar panels positioned higher than the surface of the pool water will function properly, the company recommend installing a shut-off ball valve after this component in the return line. Made from PROPYSOL, the product is resistant to UV rays, chlorinated water, sea and salt water and is free from internal metal components.

Powermaster Reduce Carbon Emissions By Over 15,000 Tonnes
In 2012, Stafford based energy-for-pool specialists Powermaster were responsible for reducing overall UK carbon emissions by 15,136 tonnes which equates to 14 seconds of all global emissions. This is the result of an electricity consumption reduction of 8,115,000 kWh units, which is the equivalent of £2,389,775 based on an average cost of 8.5 pence per kWh unit. One of the company’s key energy saving tactics is fitting variable speed drives, also known as VSDs or inverters, on pump and fan electric motor applications in private and public swimming pools. VSDs regulate the speed and rotational force (or torque) of an electric motor and reduce the energy used in-line with what the motor requires to work efficiently. Because motors used in swimming pools have a varying output requirement, installing a VSD reduces the amount of electricity used and thus the amount of carbon emitted into the atmosphere.
Patent Considered ‘Obvious’ By Examiner
The legal team working on behalf of Thermapool in connection with the Polypool application to the Patent office to issue an opinion as to whether Polypool’s patent had been infringed by Thermapool have received the Patent Office’s Examiner’s opinion. Karl Whitfield was to decide whether the differences identified would have been ‘obvious’ to the skilled person at the date of application of the Polypool patent. The Patent Office examiner concluded that it was his opinion that claims 1 to 3 of the Polypool patent were ‘obvious’

at the date of application (in light of FR2573116) and were ‘common knowledge’. In his opinion therefore, Thermapool has not infringed the patent and there is no reason to stop selling and installing the Thermapool panel system. Thermapool have seven different swimming pool insulation systems on the market only one of which was the subject of this patent dispute.

“These figures just show how effective what we do is,” said explained Geoff Renshaw, Director at Powermaster. “We typically offer energy savings of between 30-70% per annum, per facility. This scale of energy saving confirms that we can both save you money and drastically reduce your carbon footprint.” The Powermaster team has also developed and patented a unique Integrated Water and Energy Management System (IWEMS), which reduces electricity consumption and chemical costs in a swimming pool or spa by up to 70%. There is also a web-based remote system for monitoring usage and reliability. IWEMS maintains water quality by carefully dosing the right amount of chemicals, in response to the load, which can help to reduce water usage.
The ultimate environmental benefit provided by Powermaster’s range is the reduction of carbon emissions which contributes to a slower rate of global warming, as well as alleviating the risk of health problems.
