The latest in a globally proven range of portable particle counters, LaserCM provides a 6 channel model that uses laser light as a development to the standard 'white light' CM20.
The filters fitted when the ships were built were single filters, assembled with check valves and large changeover valves, into a duplex arrangement.
This configuration proved to be cumbersome and difficult to use.
In addition, support for the products was subsequently withdrawn by the supplier.
Discussions with engineers from Parker Filtration and distributor, Rotec Hydraulics, resulted in the Royal Navy commissioning a full minor trial of replacement Parker filter products.
This involved the fitting of two Parker Filtration 32PD duplex filters to the CPP systems on HMS Campbeltown.
The successful trial improved levels of cleanliness which helps to ensure the long term reliability of the ship.
The Parker 32PD high pressure duplex filters operate within the CPP systems at a pressure of 50 bar and flow of 225 litre/min.
The fluid is OM33 mineral oil. Request a free brochure from Parker Hannifin - Filter Division ...
