Smart app for pipes
DPI FlowCalc is a new app available from DPI Plastics. The app has a calculator that can be used to determine friction loss, flow resistance, pipe size, and water delivery for pipelines under pressure.
Results of the calculations can be emailed directly to the user via their smartphone. The app also allows users to email DPI Plastics’ technical department should they have any additional questions. The app can be used with most smartphones and can be downloaded for free from Google Play and the Apple App Store.

Time-saving interaction Being in control of
heat pumps
The WPM heat pump manager from Stiebel Eltron offers a variety of functions. One of them is control of a cascade of two on-off or inverter heat pumps or one direct and two mixed heating circuits. It is operated intuitively and conveniently with a touch wheel.
The Magna3 from Grundfos is the most widely ranging wet runner series with 45 types and over 220 models. It is available in sizes from 25 – 40 to 32 – 120 with pipe fittings and from 32 – 40 to 100 – 120 with flanges. The conveying capacity covers nominal pump heads of 4 – 18 meters.
Software updates to the WPM system can be installed with an SD memory card. Other features of the system include the WPE module that makes it possible for two additional mixed heating circuits to be controlled. In addition, up to four further heat pumps can be managed, which means that in total, a six-unit cascade can be used.

The twin pump designs can be run in both alternate and reverse operation, as well as in parallel in peak load operation, and thereby achieves flow rates like much more expensive volute pumps do. The Magna3 pump is flexible and reliable, and has low noise levels, long life, and no maintenance requirements.
The Magna3 is suitable for media temperatures between-10 ° C and + 110 ° C, and therefore covers a wide range of applications in heating, air conditioning, refrigeration, and industrial applications.

Keeping electricity costs out of hot water
HeatTech’ s solar line geyser is available in 100, 150, and 200 litre tank sizes. The geyser is capable of automatically switching to dual solar and / or electric hot water heaters.
The geyser combines an indirect, high-pressure full double-jacket water heating system with long life and environmentally friendly performance, regardless of weather conditions. The geyser is powered by natural sunlight; therefore, reducing electricity costs. The geyser is suitable for both flat or pitched roofs— and also absorbs maximum solar energy. Other advantages of the geyser are that it does not overheat, it requires low maintenance, and it has high density.
