Hydrovane T02 rotary compressor, extremely compact, water-cooled version with integrated, frequency-controlled controller. The Hydrovane Compressor Smart Protocol precisely adjusts the rotary speed of the compressor to suit the compressed air requirement of the vehicle.
The technical data is ground breaking: direct drive by means of a 400V AC IEC E-motor in a speed range of 800 to 3000 rpm. With a maximum pressure rating of 13Bar, an air volume flow of 6.7l/min is possible; the power consumption is 1.1. to 4.0 kW. In comparison to the previous compressor stages, this new development achieves double the volume flow and a 30% higher pressure level.
For use in the demanding environment in which local buses operate, rotary vane compression has proved to be an ideal principle for compressed air generation, which surpasses the piston compressors with its quiet vibration- and pulsation-free operation, compact design and low maintenance requirements.
Not only are many of the compressors on the market today still too loud and/or too heavy, they also require extensive cooling equipment. This means additional costs during installation and during vehicle operation.
But there is another way, as demonstrated by the extremely lightweight, compact Hydrovane T02 unit with integrated air dryer, AC electric motor and inverter technology, which is around 50% lighter than conventional DC units. Thanks to the water cooling, the unit can also be mounted in poorly ventilated, confined installation spaces in the vehicle. The inverter works with the Hydrovane Compressor Smart Protocol and precisely adjusts the rotary speed of the compressor to suit the compressed air requirement of the vehicle.
The T02 unit can be configured to suit customer requirements. For example, an air-cooled unit can also be configured with the same core components. This flexible, modular construction can be used in a huge range of vehicle types with different drive concepts and the easy integration of e-motors with even greater energy efficiency makes this compressor unit “future-proof”.
The Hydrovane T02 unit has a proven track record in the diesel-electric hybrid bus market. 3 years of series production manufacture has seen product running in London, Paris and Berlin with a number of other OEMs interested in using the product on their vehicles. Gardner Denver also plays an active role in the EU Commission sponsored “Ecochamps” Project, which is aimed at creating an efficient, compact, low weight, robust and cost effective hybrid powertrain for both commercial vehicles and passenger cars. The T02 unit is an integral part of the new hybrid vehicle configuration.
