Varisol DF

World leading technology of Thermomax direct flow tubes and unique new design combines to offer high performance and total flexibility.

The revolutionary new design of the VarisolDF product offers a modern and flexible alternative to the rigid manifold system. Quick and easy to install, VarisolDF allows individual tubes to be simply clicked together to create solar collectors of varying sizes.

Benefits for everyone

Total flexibility and high performance are not the only benefits of this unique new design. The combination of high performance polymer materials and 'click-fit' technology creates a product that is easier to order, store and install and is also more environmentally friendly.
