Fasi Gravimetric Blending System – New 2017 – Model FGB-2 – 4 Component Blending System with 2 Loading Receivers and 2 Self Contained Loaders
HiTech Automatic Screen Changer – New 2017 – Model Eo7RXL – Continuous Screen Type – Complete with Closed Loop “Cycle Time” Control.
Features of the Closed Loop – Time algorithm:
Operational modes: OFF/AUTO/TEST/MELT – Password protected – Screen advancement based on constant increments according to a Tine Based Logic Cycle. The Closed Loop-Time algorithm is used to maintain a steady incremental rate of screen travel. The rate of screen movement are operator selectable and adjustable. Screen movement is verified by the controls. Immediate indication of any malfunction in screen movement is given by means of the NO FEED alarm. The automatic cycling is stopped, and the operational mode is turned off. Variety of heating patterns for the heater (s) can be selected to customize the controls for a variety of polymer and processing conditions. All the heating zones are monitored by temperature controllers. Power consumption indicators are also included. Door handle is interlocked with a disconnect switch inside the enclosure.
Alarms (visual and audible) supplied for:
NO FEED: screen movement cycle is not completed. NO COOL: accidental loss of cooling water to the line. NO HEAT: alarm stops operation of the controls and returns to OFF mode. prevents tracking issues by not allowing the screen to advance without adequate heating conditions.
Protection supplied for:
TEST: mode has max time protection. BOOSTER and EXILT LIP heater (s) have separate protection limits against overheating in all modes. Incorrect settings of the timers. MELT mode has an additional protection against overheating of BOOSTER and EXIT LIP that allows the cooling system to expedite the drop of temperature (mainly for low flash point polymers). Incorrect mode selection when properly interlocked with the extruder.
