What makes Solex technology so efficient?

Traditional cooling technology requires high energy consumption

A common method of cooling bulk solids is direct air-cooling – for example, fluid bed coolers or drum coolers. With this method, large horsepower fans take in and blow ambient air across the product. The air is then discharged through an air cleaning system to an exhaust stack.

The challenge with using air to directly cool bulk solids is the significant quantity of air required and the expense involved in chilling, processing and cleaning that air.

Solex cooling technology requires minimal energy

Solex uses moving bed heat exchangers (MBHEs) that use vertical plate technology to cool bulk solids indirectly using fluids such as water. With this technology, the heat transfer fluid is circulated through a vertical bank of hollow stainless steel plates while the bulk solid passes between the plates at a rate sufficient to achieve the required cooling.

No air is required in the cooling process, and the energy requirements are minimized. In fact, the total energy consumption can be 90% less than air-cooling methods.

Energy savings example

Compare the energy consumption of Solex's plate-based MBHE to a typical fluid bed cooler.

Example: 50 tph facility

Energy consumption: The energy consumption of the Solex MBHE is 0.3 kWh/tonne vs 7 kWh/tonne for a typical fluid bed cooler.

Energy savings: The total electrical energy savings over five years is approximately $750,000 US.
