Process plant spares, retrofits and supportmaintenance contracts and remote diagnosis.

The pattern is consistent across plants. A small problem appears and is worked around because the line is busy. Another appears. Neither is urgent on its own, and neither gets a shutdown slot. Over a year those workarounds accumulate into a maintenance deficit, and the deficit is eventually paid all at once — as an emergency repair, an unplanned shutdown, or a safety issue. Nothing in that sequence requires anyone to be negligent. It only requires maintenance to be the thing that always gets deferred.

PTP supplies spare parts for process equipment on their own account, not only for equipment PTP installed. Filters, blower and vacuum pump parts, bearings, gaskets and sealing for various process machineries, vibratory motors and air fluidisers cover most of what actually wears on a powder line. For valve work the wear items are usually rotors, tip strips and shaft seals on rotary valves, and seals, actuators and position switches on diverters and isolation valves. Where a part is no longer made, a functional equivalent is identified rather than the plant being told to replace the whole machine.

The Annual Maintenance Contract puts the work on a calendar so it stops competing with production for attention. PTP's automation team runs a system care contract covering the health of PTP-supplied panels, the plant control system, and field instruments — level sensors, limit switches, pressure transmitters, load cells, indicators and other safety devices — with basic training for plant operators and electricians included. The contract combines a set number of engineer visits across the year with online support hours available when something goes wrong between them.

Remote support changes the economics of a fault. A large share of control system problems are diagnosable without anyone travelling: a sensor reading out of range, a sequence stalled waiting on an interlock, a parameter changed and not recorded. PTP Remote Support provides remote access for support and maintenance work, and can be extended to give the customer's own staff remote access to the same system. What used to be a next-day site visit becomes a call, and the line often restarts the same hour.

Retrofits sit alongside this. Adding a magnet ahead of a mill, fitting a metal detector before packing, putting in a diverter so a destination can be changed from the panel, adding a dust take-off at a transfer point — these are small, contained jobs on a line that already exists, and they are the most common way PTP works on plant it did not originally build.
