Ultra-efficient bulk solids heating
Solex’s heat exchangers heat bulk solids to uniform temperatures of up to 700°C while using up to 90% less energy, virtually no emissions and a significantly smaller installation footprint than traditional methods.
Waste heat from elsewhere in the facility can be captured and reused, improving efficiency and generating even greater cost savings.
And thanks to a vertically oriented modular design with no moving parts, you can quickly increase capacity and eliminate bottlenecks while reducing maintenance costs at the same time.
How it works:
Watch the Solex heat exchanger in action:
Controlled Product Flow
Indirect Plate Heating
Free-flowing bulk solids pass slowly downward between a series of vertical hollow heat exchanger plates.
Steam, hot water, thermal oil or air flow through the plates to heat bulk solids material by conduction.
The mass flow discharge feeder creates uniform product velocity and regulates product flow rate.
Bulk solids pass through the vertical heater by gravity, using no moving parts.
Dramatically increase your energy efficiency
Use up to 90% less energy
Indirect heating by conduction uses drastically less energy than other conventional direct heating equipment, such as fluid bed heaters or rotary heating equipment.
Recover and reuse waste energy
Indirect plate heating technology makes it possible to capture and use low-grade heat from elsewhere in your facility for heating bulk solids – whether through hot water, steam, thermal oil or air. The more recovered energy you have available, the greater the potential savings.
Get a consistently superior final product
Prevent abrasion or degradation
The slow and controlled movement of the bulk solids material prevents product abrasion and degradation so that there is no change in particle characteristics or quality.
Receive precise & uniform final temperatures
As it is heated, your product flows with uniform velocity through the heat exchanger with a longer residence time (usually five to 10 minutes) enabling even temperature distribution and stable, uniform final temperatures.
Significantly reduce emissions, dust, fines or odors
Because no air is used during the indirect heating process, emissions, fines, dust and odors are virtually eliminated.
Minimize installation cost and footprint
Eliminate costly air-handling equipment
Because air used does not contact the product directly, there is no need for air handling equipment such as large diameter air ducting, motors, fans, scrubbers, heaters and emissions controls.
Reduce your installation footprint
The heat exchanger’s modular design and vertical orientation make it an ideal choice for debottlenecking or revamping. You can quickly and easily increase capacity without sacrificing additional floor space.
Cut maintenance costs
Our heat exchangers use no moving parts, drastically reducing the maintenance required over time. Plates can be removed and replaced individually with easy access via a full-height access door.
