Holroyd Precision set to complete £2.4 million export order

Destined for a customer in the Far East, the order is for a Holroyd 8EX rotor milling machine; the largest machine of its type in the world. Due for delivery this month (February 2009), the 8EX machine has a swing of 900 mm and is for the production of screw rotors for the gas processing industry. “This machine is the largest rotor miller ever made, however we now have enquiries for even larger machines,” said Mike Duignan, sales director of PTG. “At present there is a rapid growth in the requirement of large gas processing systems. Holroyd is key to this development with our expertise in screw rotor profiles and design coupled with ultra rigid machine construction for high speed high precision milling to produce high efficiency screw rotor technology, which provides gas compression for a wide range of applications.” Prior to placement of the order, the Precision Components Division of the PTG Group proved the machining process for the large screw rotors, by producing pilot batches for the customer. The rotors, each one weighing over 6 tonnes, are manufactured from stainless steel to enable them to resist corrosion from the aggressive waste gases from a Styrene manufacturing process.
