SunTank solar panels

Making the most modern solar absorption technology available to the South African market.

As solar energy usage becomes more mainstream, consumers are looking to exploit the resource in the most effective way. The new Blackfusion TM absorber technology, developed in-house by our engineers, takes the SunTank solar panel another step up the cost efficiency and cost effectiveness ladder. Using Ultra thin copper substrate, chemically treated to enhance absorption and welded onto the heating manifold, the SunTank collector is at the forefront of innovation and implementation of the latest solar absorber technology.

The innovative ROLL-FORMED, light -weight panel frame is another world first, contributing to the technical superiority of the SunTank solar panel. This high precision sleek design provides for easy installation, perfect water resistance under the most severe climatic conditions and versatility of materials and finishes, to suit different type roofs.

The collector case is injection-moulded with Polyurethane and further protected by synthetic wool, giving the collector the most superior and long lasting thermal insulation properties, totally unaffected by time, radiation or humidity.

Developed by a company which is in direct daily contact with customers and installers all over South Africa for almost two decades, Blackfusion TM absorber technology combines the greatest degree of cost efficiency with the toughness and ruggedness demanded by the extreme working conditions presented by the South African climate.

Backed by the 10 year performance warrantee offered by South Africa’s leading solar heating brand, the SunTank BlackfusionTM solar panel is the most attractive proposition currently available for the South African consumer.

The glazed collector cover offers a unique combination of toughness and ruggedness with best radiation transmission, using the latest tempered prismatic glass technology.

 

Stainless Steel solar geysers – world leadership in production, research and development, made in Pretoria, South Africa.

Built to last – The SunTank Stainless Steel, solar geyser Range consists of solar geysers capacities of 100, 150, 200, 300 and 400 liters, offering solutions to a diverse range of applications. All solar geysers distributed in South Africa to inland provinces are equipped with a double jacket type heat exchanger which enables the correct subsequent connection of solar panels should the end user desire to do so.

Our Stainless Steel geyser production started at the end of the previous century. During the years our engineering and production teams have mastered the craft of fabricating geysers that last longer and perform better than the traditional alternatives. There are a number of technologies and techniques pioneered by SunTank, to name a few:

The use of  STAINLESS STEEL GRADE 1.4509 for manufacturing of solar geysers. This grade was developed specifically to handle extreme heat conditions. Solar geysers fabricated using this grade are immune to corrosion problems often experienced by water heaters that are incorrectly engineered. Of course, fabrication techniques must also be appropriate.

Our post fabrication weld treatment system was developed over the years using the wealth of experience accumulated. Our engineers are a leading authority in the field of metal treatment, making sure that every Solar Geyser produced is designed for long service.

The world first Double-Weld system, a ground breaking manufacturing technique, using state of the art welding systems enabling external as well as internal welds providing unmached weld strength and quality. This unique and exclusive welding technique in combination with top grade Stainless Steel, produces solar storage tanks guaranteed to provide long service under the most strenous working conditions.

Double jacket Solar Geysers require careful design and highly accurate manufacturing process in order to perform well once in service. Both the heat exchange performance and the durability of our double jacket solar geysers are unmatched anywhere in the world.
