Solex Technology

The vertical indirect heat exchange technology by Solex has several innate advantages that cannot be matched by traditional methods of cooling, heating or drying bulk solid materials. 

The advanced Solex heater exchanger, engineered specifically for use with bulk solids, produces a superior final product, uses up to 90% less energy that other technologies, eliminates the production of air emissions and dust, and solves a host of other issues commonly experienced in the process of cooling, heating and drying bulk solids.

Slow & Controlled Product Flow

How It Works

Bulk solids materials pass slowly downward between a series of vertical hollow heat exchange plates.

Advantage

The slow and controlled movement of the bulk materials produces a superior final product.  It prevents product abrasion and degradation so that there is no change in particle characteristics or crystal shape.

Indirect Plate Cooling

How It Works

Cooling water flows through the plates to cool the material by conduction

Advantage

The indirect plate cooling design means air is not used in the cooling process.

This design is superior because:

• It is ultra efficient, using up to 90% less energy than technologies requiring the use of air
• Emissions, dust, fines and odors are eliminated because air is not used to directly cooling the product 
• Installed capital costs are reduced due to the elimination of costly and unnecessary air handling equipment such as large diameter air ducting, motors, fans, scrubbers, chillers, and emissions controls.
• A superior final product is produced.  Since air is not in contact with the product, risks of bacterial contamination, odor contamination, and product moisture content changes, are eliminated. 
• The plates are configured to enable easy access for inspection and cleaning. The design makes it possible for individual plates to be isolated or replaced.

Mass Flow Technology

How It Works

The mass flow discharge feeder creates uniform product velocity through the cooler and regulates the product flow rate.

Advantage

Mass flow design means the product moves with uniform velocity through the heat exchanger. This feature, combined with long residence times (typically 5- 10 minutes), ensures even temperature distribution as the product passes through the heat exchanger, producing remarkably stable and uniform final product temperatures. Solex provides guaranteed final product temperatures.

Vertical Configuration

How It Works

Bulk solids pass through the vertical cooler by gravity

Advantage

The vertical configuration makes this design both compact and modular.  

• The compact installation footprint makes this design easy to integrate in existing plants and is ideal for de-bottlenecking, revamps and capacity increase
• The clever modular design means that additional heat exchanger plate banks can be stacked if increased cooling capacity is required in the future

The Solex heat exchanger design is an advanced patented technology exclusive to Solex.
