Ludowici said the contracts would be delivered progressively over the second half of this year and the first half of 2010.
Despite the downturn, Ludowici chief executive officer Patrick Largier said the company was receiving a significant level of enquiry from current and potential customers, particularly in China, Australia and South America.
He added the company had worked closely with John Finlay Engineering to win the contracts.
