User Interface
Power Knot

Orca

Power Knot products are developed in-house with customer experience in mind.
Construction
Power Knot

Orca

LFC biodigester is made of 100% stainless steel construction. The drum of the LFC biodigester is an insulated, singular continuous piece with multiple supports.
Electronics
Power Knot

Orca

All Power Knot electronics are designed, developed, and manufactured in Silicon Valley, CA.
NFC Card Reader
Power Knot

Orca

The NFC card reader on LFC biodigesters allows you to identify the source or type of waste food placed into the food waste digester and automatically create reports and charts. Quantify and track the amount of waste that a specific event or multiple events generates. To our knowledge, this feature does not exist on any other biodigester.
Load Cells
Power Knot

Orca

LFC biodigester load cells are intuitively designed to prevent accidents and tripping hazards.
Certifications
Power Knot

Orca

The LFC biodigester from Power Knot has certifications for CE, TUV USA, and TUV Canada.
NTEP Certification
Power Knot

Orca

The LFC biodigester is the only food waste digester to achieve NTEP certification. Without NTEP certification for your biodigester, reporting the weight of food waste diverted from a landfill in your corporate report is akin to fabricating the figures.
Plumbing
Power Knot

Orca

Power Knot products are developed for easy and minimal maintenance.
Arms & Paddles
Power Knot

Orca

Arms and paddles on the LFC biodigester are 100% stainless steel and welded to ensure product longevity.
Hosepipe
Power Knot

Orca

Patented, built-in stainless steel hose on the LFC biodigester.
Hands Free
Power Knot

Orca

LFC-300 and LFC-500 biodigesters have a hands free switch option to activate the automatic door. With this, an operator never needs to touch the biodigester to deposit the waste.
Drum capacity
Power Knot

Orca

All LFC biodigesters have a drum that can accommodate a large amount of waste at one time. For example, if the nominal daily capacity is 100 kg, the LFC drum can accommodate 100 kg of waste. For Orca machines, the maximum waste inside the drum at any time is significantly less than the nominal capacity. This means that the biodigester will always be full and you will have to feed the machine far more frequently than with an LFC biodigester.
