Auto de-gritting; Digester tank does not silt up, allowing consistent performance.

 

 

Auto de-gritting

Any grit, sand, soil, glass or metal that enters the digester is removed automatically. This enables the digester to consistently run at maximum capacity, without the need for a periodic shut down to remove grit.

 

 

 

Foam alleviation; Fast recovery from indigestion, can cope with any feedstock.

 

 

 

Foam alleviation

This enables the Fre-energy digester to process shock loads of high strength feedstocks containing fats and sugars that are prone to causing acid indigestion. Removing the foam allows the bacteria to recover quickly to optimum gas production.

 

 

 

Non mechanical gas agitation

 

 

 

Non mechanical gas agitation

Our AD's operate using a very low parastic load. The energy used to mix a digester with the methane gas is a fraction of that used in a mechanically mixed system.

 

 

 

 

Insultate Fibreglass roof

 

 

 

Fibreglass roof

Our thermally insulated fibreglass roof has unrivaled strength and has been proven to last over 25 years. It helps retain heat in the digester and will not blow away or puncture in stormy weather.

 

 

 

Simple mixing/loading pit; Our simple loading system is cheap, flexible and reliable.

 

 

 

Simple mixing/loading pit

Our simple loading system is both flexible and reliable; the sump provides a central drain for the site and a stone trap prevents any large objects damaging the loading pumps.

 

 

 

Plug-n-Play control system

 

 

 

Plug-n-Play control system

All the equipment required to run the process is contained in a single unit. It is delivered to site, tested and running, so only needs plumbing and wiring to the digester.

 

 

 

Remote monitoring

 

 

 

Remote monitoring

Our technical team can monitor all information from the control unit and CHP online. They can ensure that the system is achieving optimum performance and alert the client or a Fre-energy engineer of any potential problems.

 

 

Standard agricultural tanks; Agricultural tanks constructed, cheap and quick to install.

 

 

 

Standard agricultural tanks

We use standard agricultural tanks either made from glass enamel steel plates or precast concrete panels, these are quick and easy to erect and are significantly cheaper than poured in-situ or stainless steel.
