Professional purge unit is easy to use and enables low pressure purging to be carried out safely according to the Institution of Gas Engineers and Managers document UP/1 and 1A. It is quick and simple to set to the correct velocity to minimise gas emissions to the atmosphere -no calculations are required. The unit can be used for setting up meter regulators under flow conditions to save a second visit when appliances are being commissioned.
The complete package is contained in a durable aluminium framed box. The MPU purge unit is designed for the direct purging of pipework up to 150 mm bore from air to low pressure natural gas. It can also be used for natural gas to air purging but an air mover must be used which is available as an optional extra item. The MPU unit can also be used for setting up meter regulators under flow conditions.
