Multiple distribution system from Regloplas
More process reliability: 4 to 16 temperature control circuits and temperatures up to 180 ° C can be individually controlled and monitored with the multiple distribution system.
Parallel temperature control circuits offer several advantages over serially connected ones. At least Regloplas AG, St. Gallen / Switzerland, is convinced of this and has recently started offering a multi-manifold system for large injection molding machines. In the production of a form are often different Temeperierkreise necessary. If these are connected in series, they are dependent on each other and susceptible to temperature fluctuations. These fluctuations can only be countered with additional energy supply - be it for heating or for cooling. Or the different temperature control circuits are connected in parallel and thus independently of each other. This eliminates the risk that the temperature difference between the first and last circuit or consumer becomes impermissibly high. At the same time possible calcifications and blockages in one of the circles no longer affect other circles. Also for smaller temperature control units However, investing in a multiple distributor often pays off only for a certain machine size. Today, temperature control circuits connected in parallel are therefore only common on large production machines and the distributors are attached to the machines, not to the temperature control units. "Our multi-distribution system can also be combined with smaller devices," explains Andreas Kuhn, Head of Research & Development at Regloplas. A quad distributor for temperatures up to 160 ° C with individual flow control of each circuit is available as standard, with up to 16 temperature control circuits possible for temperatures up to 180 ° C. However, it is likely that four to eight-way distributors will remain on the temperature control unit, Kuhn suspects. "This can save costs and energy, and fewer temperature control units are needed." Fully integrated into the controller The key advantage of the multiple distributor is that it is fully integrated into the control system with sensors, monitoring, displays and controllers. Each circuit is set individually and monitored in parallel. This results in a monitoring window with constant flow and return control - and when the temperature runs out of the window, the system sounds an alarm. The monitored parallel connection significantly increases process reliability. At the same time, according to the manufacturer, the full flow with complete pump capacity can be used in parallel temperature control circuits, which would not be possible serially.
