Optimized fertilizer cooling

Solex moving bed heat exchange technology guarantee highly efficient thermal performance and ongoing reliable operation for cooling fertilizer without product caking. The proprietary process, which uses vertically orientated plates to indirectly cool the product, is designed for long-term operation without the need for regular cleaning as the unit prevents the formation of condensation and therefore product caking.

Each unit is custom designed taking into account:

• Type of fertilizer

• Required thermal performance

• Local ambient conditions

• Selection of optimum water temperatures

• Selection of optimum purge air flow rate and dewpoint to prevent condensation

Watch how our moving bed heat exchangers use vertical plate technology to indirectly cool fertilizer and phosphates:

"The CAN [fertilizer] plant started up on June 5, and until now [September], the Solex cooler hasn’t needed cleaning yet and is working perfectly. [After one year of operation] the operators already forgot [about] the coolers.”

Gemlik Gubre Sanayii A.S., Turkey

“Of all the engineering packages I received for the project, Solex’s was the most complete and thorough.”
