Building a spare parts warehouse is the responsibility of anyone who is serious about the cogeneration business. Motorgas has a central warehouse with a total area of 1000 m2 in Prague. We keep in stock not only spare parts of the sudden need (emergency), but also a robust amount of spare parts - rebuild semi-sets, which we use in exchange to reduce downtime during major repairs. This reduces operating costs. Typically, cylinder heads or engine blocks are not always needed new, but cost-effective is to use a remanufactured, replaceable method.
