Highperformance Ensiling Systems
More than 30 years in the fish industry refined into a new, optimized design.
The PowerEnsiler is based on more than 30 years of hands-on experience with silage production in the aquaculture industry.
It is developed for continuous operation in demanding environments where hygiene, reliability, and process stability are critical.
Rather than adding unnecessary complexity, the design focuses on efficient flow, integrated cutting, and controlled operation.
The result is a robust and predictable system that supports stable silage quality and longterm operation.
Key focus areas:
• Fast ensilingconsistently high quality
• Hygiene-focused design
• Fully acid-resistant components

Why silage matters
Strong biosecurity is essential for productive and sustainable aquaculture.
A key measure to reduce the risk of disease spreading is the safe and routine removal of mortalities and by-products from the production environment.
By adding 2.5% formic acid, fish silage can be produced with a pH of 3.5, enabling aquaculture operations to significantly reduce disease risks while creating a stabilised and valuable product.
• Improves biosecurity in aquaculture systems
• Converts mortalities and by-products into valuable fish silage
• Enables safe storage and transport of organic material
One integrated system from a single supplier
The PowerEnsiler is delivered as a complete Landia solution, with all critical components manufactured by Landia based on decades of experience with silage production and storage systems.
This ensures full compatibility and clear responsibility throughout the project.
The system can be supplied with tanks in polyethylene (PE) or acid-resistant stainless steel AISI 316, including ATEX-approved configurations. Tank sizes from 1 m³ to 25 m³.
If the silage is intended for biogas production, a dedicated hygienisation solution is available.
Why this matters:
• One supplier, one responsibility
• Stainless steel or PE (polyethylene)
• Available in ATEX configuration
PowerEnsiler: the Principle
The offset inlet uses centrifugal force to guide the fish directly into the chopper pump.
The pump’s knife system ensures immediate processing as the material enters the tank.
By removing zones with fresh fish, the design reduces the risk of decay and unwanted build-up.
The controlled flow contributes to improved internal hygiene and consistent high silage quality.
Design principles:
• Direct flow into the chopper pump
• Fast ensilingconsistently high quality
• No accumulation of untreated material
One control system for the entire process
The entire ensiling process is managed from one control system, handling both the ensiling tank and the storage tank.
This provides clear oversight and consistent control of all critical parameters.
Automatic acid dosing ensures consistent pH levels and stable silage quality.
Discharge is handled via electric, pneumatic, or manual acid-resistant valves, allowing the system to be configured to site-specific requirements.
Control benefits:
• Centralised process control
• Stable and repeatable operation
• Consistent product quality
The Heart of the System: the Landia Chopper Pump
• The Pump
The integrated Landia Chopper Pump features AISI 316 stainless steel pump components, ensuring excellent resistance to the low pH levels found in fish silage.
Its compact design features a short, fully balanced pump shaft and impeller, supported by heavy-duty bearings for reliable operation.
The pump is equipped with double mechanical seals separated by an oil chamber, providing maximum protection against silage leakage.
• The Chopper
The knife system is fully integrated inside the tank, eliminating the need for external grinders. Pump knives working against counter-knives efficiently macerate fish and media into a homogeneous and pumpable silage.
Integrating the cutting system inside the tank reduces the number of external components, simplifies installation, and lowers maintenance requirements, while also minimizing exposed surfaces and potential contamination points.
