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.

The reason customers think "I want to come back" often lies in surprisingly minor details. In particular, the "scent experience" in private spaces like restrooms is a testament to cleanliness and comfort. The model we are introducing this time is the compact MFmini, which is easy to install even in restrooms. It can be implemented starting from 4,400 yen per month. It is suitable for scenting restrooms and small private spaces. The Majesta Fragrance is appealing because it can be introduced to your space with low initial costs. A free trial installation is also available. If you are considering scenting for restrooms or small spaces, please feel free to contact Majesta Fragrance.
