    It's called inking unit temperature control. The purpose of this is to keep constant temperature of inking rollers which is important to keep constant colour especially in long runs.
    You can run the machine without it but is worth to fix it especially in where you live.
    What's the problem with it?

    Additionally, if circulation is disrupted on a press equipped with chill rollers, the seals in the rotary unions will be destroyed.

    In some machine you can not tun without this thermoregulation system , because there a relation between thermoregulation system and dampending solution especially if you have one motor .
    It give error lack thermoregulation solution and the temperature of dampending system will be down .
    So you can not run without this system

    I see that you have a Patreon account. Wondering if this "correction" will come with an invoice attached?

    The flow of water through the ink roller is an important process in the printing process. In an offset printing press, water and ink must be handled very precisely to obtain high-quality prints. The water circulation system is specially designed to keep the ink and ink residue on the printing plate and cylinder.

    The process involves using a watering system that distributes a large amount of water onto the printing plate. The water creates a film layer on the non-image areas, driving the ink away from those areas and allowing it to adhere to the photo areas. This method ensures that only the photo area receives ink, resulting in accurate and clear text.
