Elution Heaters

Whether you are looking for a Zadra or split Anglo (AARL) elution circuit for your mine site, Heat Systems has the complete equipment package for your needs. Our heaters can come as either a direct eluate heater, or as a thermal oil heater (where the heat is transferred from the oil to the eluate via a suitably sized heat exchanger). Both versions can be sized specifically to suit your exacting requirements.

A direct eluate heating solution within a Zadra circuit is the most cost effective and less complex of the elution heating solutions. The direct heating of the eluate allows for poor site water quality, ease of management and less components that need to be maintained and replaced.

The indirect elution heating solution requires more infrastructure than the direct eluate heating option, such as multiple heat exchanges, piping and control points. Additionally, this style of heating requires a heat transfer fluid to absorb the heat and then transfer that heat into the eluate through the Primary heat exchanger. Although this is a more complex solution, it is widely used due to the ability to manage the circuit more finitely.

Heat Systems standard thermal oil heaters and direct eluate heaters are LPG, Natural Gas, Diesel or electrically fired, while custom designed heat plants are available on request for clients looking to utilise waste heat, solid fuel or heavy fuel oil.

Control system options are available to suit the needs and budget of any project. Starting with basic relay logic panels and progressing through to programmable logic controllers with touch screens and the latest technology air/fuel ratio burner management systems.

Whether the unit required is indirect elution heater or direct eluate heater, all units come skid mounted for ease of transport and installation.
