A Dutch maker of valves, couplings and flow regulators claims it has developed what it calls a “sustainable 700-bar filling technique” for hydrogen cars.
The company, Teesing, says its PusH project successfully filled cylinders fast and efficiently with hydrogen at 700 bar.
The system runs at 700 bar because hydrogen has a lower energy content than natural gas, which means that the same volume contains three times less energy.
Refuelling hydrogen at a higher pressure, 700 bar, supplies enough energ
Trimble is offering a new version of its Trimble GCS900 grade control system designed for use with milling machines. The new package allows contractors using planers for road repairs to achieve material savings and increased road smoothness during the ensuing paving operation. By controlling the cutting depth of a milling machine accurately, a contractor is less likely to make an overcut in the areas being repaired and as a result, is less likely to require additional asphalt or concrete when paving the new
A Wirtgen SP 62i slipformer has been used for the cost-effective paving of concrete slab in the US state of Texas. The machine has been utilised for construction work in College Station, a town some 150km northwest of Houston, Texas.
