WITTMANN, together with its partner company innovenergy, brought direct current (DC) injection molding technology up to series production.

innovenergy specializes in installing DC networks in industrial plants and other areas, as well as developing and producing particularly sustainable solar power storage batteries operating with sodium chloride (common salt).

The interim storage of solar current in batteries is also significantly more energy-efficient in DC networks than with using alternating current (AC) networks and inverters.

WITTMANN has extended the range of injection molding components available for use in DC networks by adding temperature controllers.

WITTMANN expands DC injection molding components to temperature controller.

The new Tempro plus DC offers same high performance rates as the conventional Tempro plus AC-powered models. For instance, the Tempro plus D90 DC, suitable for temperatures of up to 90°C, has a heating capacity of 9 kW with 750 V DC. The cooling capacity is 40 kW for a differential temperature of 75 K.

The DC version already comes with a 1.1 kW synchronous motor and an inverter as part of the standard equipment package. The motor drives a seal-less submersible pump with a maximum working pressure of 7.5 bar and a maximum flow quantity of 60 l/min. In cavitation-free operation, practical values of up to 40 l/min and 5 bar are reached.

The inverter enables direct connection to the machine’s interim circuit as well as speed control in line with the desired process parameters. In this way, conversion loss is prevented and the pump speed is adapted to the requirements of the process. The result is a two-fold increase in energy efficiency.
