Thermoregulation units that combine direct heating of thermal oil (via a burner or electric resistance) and temperature control of a fluid to the users via a mixer or indirect system in a single device. Suitable for temperature control of multiple users without an existing thermal fluid network. Electronically controlled via a microprocessor system with 4-20 mA control, they are equipped with a secondary and primary circuit circulation pump, primary circuit heating elements, expansion vessels, a power panel, a control panel, mixing units or high-efficiency exchangers, and certified control and safety systems. Available in versions for design temperatures up to 350°C and for power outputs up to 2 MW.
