High-pressure geyser technical specifications
The high-pressure systems are available in a Stainless Steel series and a Green & White series. The differences are explained below.
Available models:
| Stainless Steel Series | Green & White Series |
| 10 Tubes per 100L | 10 Tubes per 100L |
| 100 Litres - 10 x 1.8m Tubes | 100 Litres - 10 x 1.8m Tubes |
| 150 Litres -12 x 1.8m Tubes | 150 Litres -15 x 1.8m Tubes |
| 200 Litres - 20 x 1.8m Tubes | 200 Litres - 20 x 1.8m Tubes |
| 250 Liters - 25 x 1.8m Tubes | 250 Liters - 25 x 1.8m Tubes |
Guarantee:
| Stainless Steel series | Green & White series |
| 5 Years | 2 Years |
Outer tank material:
Stainless Steel series - 0.4mm Stainless steel sheet.
Green & White series - 0.4mm White steel sheet.
Inner tank material:
Both series' inner tank consists of 1.2mm SUS 304 stainless steel.
Insulation material:
Both series have 55mm thick polyurethane foam between the inner and outer tank.
Weight:
The high-pressure tanks can weigh up to 50kg.
Pressure:
| Stainless Steel series | Green & White series |
| 500kPa | 500kPa |
Evacuated Tubes:
- This is a standard 1800 mm length x 58 mm diameter x 2 mm thick glass tube. These tubes are designed to withstand 38 mm diameter hailstones.
- Heat transfer into the high-pressure tanks is done with copper heat pipes. Heat pipes utilize a liquid which boils and condenses, thus causing an effective heat transfer cycle.
- There is no water inside a high pressure vacuum tube. Thin aluminium plates and a copper heat pipe transfer the heat from the hot black inner vacuum tube to the tank.
Optional electric backup system:
All models can accommodate a standard 32 mm screw-in South African electric element with pocket. It can be controlled with either a thermostat or an SR609 programmable controller.
SR609 smart controller:
The SR609 is a programmable electronic control panel. The features include:
- The display of the water temperature inside the tank that is measured by a probe that fits inside the pocket of the element.
- It can be set to heat the water in the tank electrically in three cycles of time and temperatures.
- Default: if the water is cooler than 54oC between 4 and 5 am, the water will be heated to 60oC. The same happens between 5 and 10 pm again.
- A manual button raises the temperature up to the programmed temperature (usually 60oC), whenever needed.
- There is a battery backup, so it will not forget its settings.
The choice between low and high pressure:
If you want to keep your municipal or pressure pump pressure, a high-pressure system is the better choice. You will have less available hot water compared to the low-pressure systems, because high-pressure geysers do not store hot water in the tubes like low pressure systems.
