Gefran Launches the New GRM-H Power Controller
Gefran – Italian multinational specialising in the design and production of sensors , instrumentation for industrial process control , and automation systems – presents the GRM-H power controllers with integrated diagnostics , based on the scalable GRx platform , dedicated to the control of resistive loads in industrial heating . The solution is characterised by an ultra-compact design and by the IO-Link interface , which guarantees advanced features in an Industry 4.0 perspective . “ The new GRM-H are capable of meeting the needs of a wide range of applications , where high performance in temperature control is required : from the heat treatment of metals , to the production of glass and processing of plastic materials , to semi-conductors , up to the food and pharma sectors ” said Paolo Buzzi , Gefran Controllers & Power Controllers Marketing Manager , who continued “ In particular , this innovative series integrates the typical characteristics of a power controller within the dimensions of a solid state relay ( SSR ). Available in current sizes from 15A

to 120A , they guarantee easier installation and enable the management of linear and non-linear resistive loads , such as MoSi2 , Sic , SWIR , graphite and transformers ”. GRM-H are single-phase power controllers , which in a Master / Slave configuration also enable the control of threephase loads . They are equipped with all the main firing mode technologies , from Zero Crossing and Burst Firing , to the Half Single Cycle and Phase Angle , useful for adjusting control according to the various characteristics of the heating elements . Also , in addition to the Soft Start function , ideal for IR Lamps , they provide Feedback algorithms that make the regulator a constant source , with modifiable voltage , current or power set points . An important advantage for certain types of resistors , such as silicon-molybdenum , silicon carbide or graphite resistors . A particularly distinctive element of the GRM-H series is the IO-Link connectivity . These are the first power controllers in the

world to adopt this protocol which enables digital communication from the field level to the higher factory level . Therefore , in addition to cyclic process data , you can also record acyclic variables such as hours in operation , temperature peaks , energy and internal temperature , for the purpose of the machine ’ s efficient predictive maintenance . Thanks to the smart configuration through the Gefran NFC APP , available for Android and IOS , you can quickly set up the main parameters and easily read the diagnostic data . This interface also makes it possible to easily duplicate the configuration on multiple devices or send it via file to the support service , which will analyse it remotely and modify it , if required .
No-Dust Granulators
CMG Granulators will be , with distributor Piovan Mexico , at Expo Plasticos 2023 in Guadalajara , Mexico from 28 to 30 March 2023 ( stand 1112 ). Expo Plasticos is the international exhibition and business forum specialized in presenting the most advanced technology in machinery , raw materials , peripheral equipment and plastic solutions for all industries . The new CMG series of G17 granulators is designed to obtain the most homogeneous regrind

shape and dimensions , along with little to no presence of dust . One additional very unique benefit of this new line is the ability to produce regrind with very small dimensions . The great advantage of dimensionally small regrind is the possibility to add higher percentages to the virgin material with no influence to the quality of the finished product . Small capacity systems , injection moulding machines or extruders , are equipped with small diameter plastification screws , unable to process granules with dimensions exceeding those of the virgin granule . The G17 granulators produce rigrind which is dimensionally comparable to the virgin pellet . With Headquarters , Production Site and Technical Center in Italy , and the largest distribution network in the plastics industry , CMG is active all over the world with localized technical service , spare parts and sales centers .
