What's the bulk solid plate heat exchanger?
3.Indirect cooling by conduction, no cooling air is required.
4.A mass flow feeder regulates the solids flow at discharge.

Solex bulk solids cooler/power flow cooler has installed more than 60 coolers of this type in fertilizer plants around the world, cooling virtually every type of granular and prill fertilizer - urea, ammonium nitrate, NPK's, MAP, DAP, etc. The basis of the bulk solids cooler technology is the gravity flow of product moving through a bank of welded heat exchanger plates, cooled with water.
Why So Many Factories Install the Indirect Plate Heat Exchanger?
1, Lower the packing temperature below 40ºC, solving the caking problem
2, Reduce energy consumption and emission
3, Compact design with simple system
4, Easy to install with small installed space
5, Increase plant competitiveness
6, Low maintenance cost
The Challenges, the traditional fluid bed cooler/rotary drum cooler has to face the below problems:
1, High packing temperature causes product degrades and cakes during the storage
2, Energy consumption not sustainable due to very low profit margin
3, Emissions above the new limit legislation

The heart of the bulk solids cooler is the bank of exchanger plates. The product to be cooled flows slowly between the plates. Cooling water flows through the plates in counter flow and the product is cooled by conduction. Mass flow of the product is achieved by means of a discharge feeder mounted as an integral part of the exchanger below the plate bank. The discharge feeder also regulates the flow of product through the exchanger to keep it full at all times.
Chemequip manufacturing plant is equipped with four sets of large-scale model fiber laser welding machines so that we can guarantee a high-quality plates and a shorter delivery time.
