Our client Monometer have specialised in foundry and furnace equipment since 1913. They approached Filter Designs because they were installing a new plant in Rwanda Africa which required a filter to capture particulate from copper smelting fume.
The one tonne liquid copper capacity rotary furnace has an air volume of 25,000Am3/hr.

Our supply scope consisted of:
As this project was destined for Rwanda this was a supply only.

Due to the size of the filter, we needed to get it crated for sea freight as it had to be shipped on an open top container and would be open to the elements.


The control panel was a simple push button panel which housed the inverter for the centrifugal fan with control via a pressure transmitter in the ducting or with a potentiometer. Due to the environment being potentially dusty we opted to also house the reverse jet pulse controller in the panel as well as the digital display for the thermocouples. The control panel was completely FAT tested prior to shipping and we provided an in-depth operational guide for the operatives on site.


Once the filter arrived the site installation team erected the filter using the installation guide we provided with associated drawings to facilitate.

Commissioning is yet to take place, but we are still in contact with our client and will offer support if and when it is needed.

We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
