BOWMAN HELPS CUT FUEL COSTS AT AUSTRALIAN VINEYARD

Posted: Thursday 18th October 2012

Super-efficient Bowman heat exchangers are helping to minimise fuel costs and emissions on an Australian grape farm. The Bowman units were supplied as part of a new irrigation system which was designed by consultants, Riverina Water Engineering and supplied via Bowman’s Australian distributor, Luxford Marine Industrial Solutions.

The 165 hectare Farm 8a Benerembah in New South Wales produces a wide range of grape varieties. Some of the vines are up to 800m long which means the irrigation pumps require high operating pressures, making it difficult to control the fuel consumption of the system.

To address this problem, Riverina Water Engineering designed a new turnkey drip irrigation system designed to operate with the lowest practical fuel consumption without jeopardising the integrity of the system.

The pump sets include two Iveco 6.7l after cooled turbo charged engines which were bought without radiators or a cooling system. Instead, Riverina Water Engineering retrofitted them with Bowman GK190 charge air cooler and an FH300 header tank heat exchanger in place of the radiator and turbo air cooler. Filtered irrigation water cools the air from 140O C to 50OC. The Bowman units have contributed to the efficiency of the system, which now uses just 13l of fuel per hour per engine.

Bowman header tank heat exchangers and charge air coolers were chosen as they are highly effective ways of cooling both incoming combustion air, as well as engine coolant in diesel engines. The high level of cooling efficiency of the Bowman units has helped ensure the Iveco diesel engines run at their optimum temperature, aiding fuel efficiency – even in the testing climatic conditions of a New South Wales summer! Additionally, should it be required, the Bowman units can also be used to recover waste heat from the engine and convert it to a valuable energy source for heating or hot water and at no extra cost in terms of fuel usage.

Bowman manufactures one of the most comprehensive range’s of heat exchanger’s to recover waste heat from exhaust gases, jacket water, fuel, oil and charge air systems. They are all highly efficient, both in terms of controlling the engine’s operational temperature, as well as recovering waste heat from the engine and converting it into a valuable and free energy source for heating and hot water.

All Bowman units are available in a variety of materials to suit even the most demanding operational requirements and an important design feature of the heat exchangers is the ability to easily remove the tube stack for routine cleaning and maintenance.
