H+E has recently received a new order for an IBC level control and chemical transfer system for two chemicals from a client in the Pharmaceutical sector.
A number of H+E’s clients commented about the amount of chemical commonly wasted when dosing from Intermediate Bulk Containers (IBCs). This problem really relates to the fact that there is no level control included within IBCs that tell the user when the IBC is empty but, even if there were, when using chemical non-stop 24/7 it is totally impractical to have an operator standing by the IBC ready to change it immediately once it is empty (especially if that occurs over a weekend) and, even if you did that, there is still a substantial time when the chemical is not available, simply because it takes time to disconnect one IBC, remove it, replace it with a new one and then connect it.
H+E therefore developed its IBC level control system to address these issues, and the system has been used by our clients to work with a range of chemicals from standard dosing requirements to rather unusual needs, including dosing of tartaric acid.
System allows non-stop 24/7 operation
The system basically provides an external level control with a “buffer” volume of chemical that allows an alarm to be generated when there is no more chemical leaving the IBC whilst maintaining flow to the point of use. This means that you can connect two IBCs to the system on a “duty / standby” basis, with automatic valves that automatically switch the on-line IBC and also generate an alarm to advise that the empty IBC should be replaced.
You can also have a system with just a single IBC connected if you wish, perhaps because chemical consumption is low and only periodic.
You can also have either single or duty & standby chemical transfer pumps
Depending on its location, the level control system can be built inside an enclosure to provide weather and frost protection. Also, the chemical IBCs can be located inside enclosures.
In this particular case, the system is located outside and handles two chemicals, with duty and standby IBCs.
The Level control unit is inside an enclosure and the IBCs have electrically-heated jackets.
The chemicals are transferred inside the factory via dual-contained pipework to “Point of Use” tanks.
