Within a year, DEIF’s anti-knocking module saved us more than 7,000 euros
Efficiency improvement cuts payback time
The installation of the new and contemporary solution not only brings easier operation. Nimtofte Biogas has also registered a considerable efficiency improvement.
“With the old system, we had a 34% efficiency ratio. The new system has elevated this to just below 39%. For a period, we have even been constantly above 40%”, Steffen Thorsen states.
Kristian Thorsen attributes the main part of the progress to the new RMG gas mixer and the power management system from DEIF. Due to the optimised efficiency of the entire plant, he estimates a return on investment equal to approximately one year.
Asked directly if he believes the DEIF controlled solution has led to specific cost saving advantages, Kristian Thorsen replies that due to the flexible controller he and his staff face practically no downtime and less service checks.
As a day of downtime costs around 1,800 Euros in total, it is absolutely crucial that the system remains in operation all the time. High commitment and constructive dialogue Kristian Thorsen describes the commissioning period of the anti-knocking system as a bit challenging because it was a new solution and a first in terms of combining Nimtofte Biogas’ specific engine type with DEIF’s regulator.
“On the other hand, that gave me the opportunity to experience the high level of engagement of DEIF’s project team. Really dedicated and focused on finding the right solution. Our dialogue has been and remains very positive. I feel our input is appreciated and taken seriously. A gas engine breakdown easily costs more than EUR 2,500 in repairs and EUR 1,200 per day out of operation. Within the first year, the AKR from DEIF saved us twice that amount."
