From the days when our forefathers began draining roofs, gravity has been the driving force to move the rainwater from the roof to the ground. However, our 21st century technology offers a superior alternative to cater for the storm profiles that today’s changing climate brings us. Our solution is available now and it’s HydroMax™.
(In some markets e.g. USA, cost savings of 65% can be achieved)
From the Finnish engineer Ovali Ebling’s early conceptual origins to utilize negative pressures generated by the building height to draw the water from the roof, the market for siphonic roof drainage has grown tremendously in many countries throughout Europe, the Far East and Australasia. Already available worldwide, HydroMax™ is the new drainage system to take the world by storm.
Our partnership with Tyler Pipe Company's Wade Drainage division has seen the launch of the Wade-HydroMax® drains using the USA version of HydroTechnicTM design program (available from Wade).
HydroMax™ was developed to advance the siphonic principles to create a powerful means of literally sucking the rainwater from the roof. Using small diameter pipework running at full-bore flow, HydroMax™ can provide ten times more flow capacity than an equivalently sized gravity system on a single storey building.
HydroMax™ - bringing tomorrow’s technology today.
To enable HydroMax™ to drain with such high performance, the system designer utilises our sophisticated HydroTechnic™ analytical design software program to optimize an Engineered Drainage Solution and is unique in having been independently tested by HR Wallingford (one of the world’s leading Hydraulic Research Establishments) for compliance with the performance requirements of BS EN12056-3:2000.
HydroMax™ siphonic roof drains are also tested in accordance with ASME 112.6.9, the world's most recent siphonic roof drain standard.
The key to the functionality of any siphonic roof drainage system is the sizing of the pipe system to balance flow rates in the outlets. The web-based HydroTechnicTM software is the most technically advanced in the industry, allowing fast and accurate calculations to be carried out on the most complex systems.
Why use a HydroMax™ Siphonic Roof Drainage System?
HydroMax™ is an innovative high-performance roof drainage system which utilizes the power of a siphon to route small diameter rainwater pipes horizontally without gradient to the perimeter of buildings thus eliminating drainage under the building floor whilst offering significant cost savings.
We hope to bring more of our pages of our web-site to you in your language in the near future.
