Graham Corporation, a manufacturer of equipment for the oil refining and petrochemical industries, has received two orders for ejector systems that total approximately $4m.

The first order is for an ejector system to be installed at a US refinery that is being modified to process crude oil from the Alberta oil sands.

The ejector system is slated for delivery in the third quarter of Graham’s 2012 fiscal year, which begins on 1 April 2011.

The second order is for an ejector system destined for a refinery expansion in China.

The delivery for that system is planned for the second quarter of fiscal 2012.

The company said that the ejector system for China is expected to have certain of its components built in China.

Graham has also received orders of $17.8m in its fiscal 2011 third quarter.
