Gardner Denver Introduces T02 Hydrovane Rotary Vane Compressor

Gardner Denver Transport is concentrating on innovative solutions for equipping local transport and commercial vehicles with auxiliary units. Overall, electric drives must be designed to be as effective as possible for use in (partially) electrified drive systems. Here, the compressed air supply for door openers on city buses is just as much a focal point as the use of electrically-driven power steering pumps, for example. The efficiency of the entire system thereby depends on the interaction between the on-board technology and on-board electronics. Undesired effects during later use, caused by inadequate interface of the subsystems, must be prevented. 


The Hydrovane T02 rotary compressor, an extremely compact, water-cooled version with integrated, frequency-controlled controller.


This is where Gardner Denver excels, with its core product, the new Hydrovane T02 transit module for compressed air generation. This rotary vane compressor module was specially developed to provide maximum space savings and weight reduction, along with the lowest noise possible while ensuring maximum energy efficiency.

The technical data is groundbreaking, the Hydrovane T02 has a 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, and 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 where local buses operate, rotary vane compression has proved to be an ideal principle for compressed air generation. Rotary vane compressors surpass piston compressors with their 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 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, around 50% lighter than conventional DC units, compact Hydrovane T02 unit with integrated air dryer, AC electric motor and inverter technology. Thanks to 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. Three years of series production manufacturing has seen the 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, 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.
