Title (EN) GAS HEATING SYSTEM WITH HIGH-PRECISION TEMPERATURE CONTROL
(FR) SYSTÈME DE CHAUFFAGE AU GAZ À HAUTE PRÉCISION DE RÉGULATION DE TEMPÉRATURE
(ES) SISTEMA DE CALENTAMIENTO A GAS DE ALTA PRECISIÓN EN EL CONTROL DE TEMPERATURA
Abstract:
(EN) The present invention relates to a gas heating system with high-precision temperature control, which comprises: at least two combustion chambers, one connected to a barrel containing a mouldable material and the other connected to a dispensing area; a recirculation mechanism; and control means. The present invention provides a system configured with two chambers and two areas, which configuration has a proven effect on temperature control, the system being connected to barrels for injecting or extruding mouldable materials and improving the efficiency of these processes.
(FR) La présente invention concerne un système de chauffage au gaz à haute précision de régulation de température, comprenant au moins deux chambres de combustion, l'une associée à un cylindre renfermant le matériau moulable et l'autre associée à une zone de dosage, ainsi qu'un mécanisme de recirculation et des moyens de commande. La présente invention permet d'obtenir un système doté d'une configuration bi-chambre et à deux zones, apportant un effet prouvé de régulation de la température associée à des cylindres d'injection ou d'extrusion de matériaux moulables et améliorant l'efficacité de ces procédés.
(ES) La presente invención corresponde con un sistema de calentamiento a gas de alta precisión en el control de la temperatura que comprende al menos dos cámaras de combustión, una asociada a un barril que contiene el material moldeable, y otra asociada a una zona de dosificación, asi como un mecanismo de recirculación y unos medios de control. La presente invención entrega un sistema con una configuración bicameral y de dos zonas que aporta un efecto probado en el control de la temperatura asociado a barriles de inyección o extrusión de materiales moldeables y mejora la eficiencia de estos procesos.
