In addition to the fact that the pre-assembly dramatically reduces stocking expenses and EDP documentation, the company from Münster can also react more quickly to sudden surges in demand on the market. If the sector is booming, they can maintain short ordering deadlines. This pays off for 2G, since the WAGO connection electronics can be ordered using a single item number: “WAGO has gotten to know how we work here. If demand peaks, we inform our suppliers quickly,” Design Manager Jörg Schmiemann describes the closely entwined supply chain.
In his view, pre-assembled control cabinet components offer additional advantages: reduced risk of error, thus higher quality and system availability. “To begin with, our customers want to reduce energy costs, and at the lowest possible expense. Because the systems function efficiently, the amortization period for investing in a CHP is rather short,” Schmiemann explains the advantages of the 2G CHP. The systems convert up to 42% of the gas into electrical power due to specialized fine-tuning. “A standard motor achieves 38%.”
2G’s specialty is optimizing this point, explains Schmiemann. “We optimize our systems depending on the different types of gas, because sludge gas, biogas, and natural gas all have different knock limits,” explains Liesner, adding that 2G also develops their own spark plugs and cylinder heads. “We began with an efficiency of 38.7%, and now we are at 42.5%.” While it sounds like a modest increase, the cost savings in gas for this motor class amount to several tens of thousands of euros per year – over the system lifecycle of ten or more years, this can recoup the majority of the total investment.
