Besides the development and manufacture of quite new vacuum furnaces, in the long term the PZP KOMPLET company provides also service of older vacuum furnaces, for example Tesla PZ 810. Most of those devices have older dates of manufacture, individual assessment of their condition is thus necessary any time. Very often we encounter the devices the operation of which is not economic for the users due to their repeated repairs. In the interest of the customer, in such cases we are able to offer either partial or general reconstruction of the vacuum oven.

In the first stage of works, the whole device was disassembled up to the last screw. We blasted the frame of the device, applied its new coating and modified fastenings for new components.

In the device, there were set a new switchboard with microprocessor control system, a water distributor, new vacuum distribution lines, a new rotary vacuum pump, furthermore vacuum gauges, temperature gauges, electro-pneumatic valves, gas distribution lines, plate valves, hydraulic distribution lines, new glands in full, bellows connecting pieces, flow meters and hoses. It was also manufactured a new casing.

Afterwards, there were disassembled all the vacuum parts, cleaned water circuits, trimmed all contact areas and, as needed, varnished component parts and everything was retested. In this specific case, only the parts of heating, hydraulics shielding, the transformer and the vacuum diffusion pump of the original device has been reused after their renovation.
