Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.
