NuArc’s largest screen exposure system offers the ultimate in computerized touch-screen operation. Job Recall™ allows operators to program Helios™ to repeatedly perform numerous screen exposure sequences—from automatic door closing through automatic lamp centering (on larger models), vacuum draw down, screen exposure, vacuum release, blowback, and door opening. Helios models use powerful instant-start 6 kW multi-spectrum metal-halide screen exposure lamps to speed production while retaining fine lines and dots. Dual 6 kW metal-halide screen exposure lamps are standard on models designed for screen sizes of 208 x 269 cm (82” x 106”) and larger.

Computer-generated diagnostics monitor all functions to quickly identify and resolve problems. The computer-directed pneumatic door prevents the blanket frame from twisting, and it frees operators from the tedious task of manual operation. NuArc’s Light-Loc™ automatically shuts off screen exposure lamps if the door is opened, allowing Helios to be located in light-safe screen-coating rooms. The screen exposure area is angled to ease screen loading and glass cleaning. Standard features include improved heavy-duty blanket material, automatic blowback to release vacuum, and a static electricity reduction system. With six standard models and a wide range of custom sizes available, there’s a Helios for virtually any need. Standard models are sized to accommodate maximum screen frame sizes from 152 x 183 cm (60” x 72”) to a phenomenal 239 x 457 cm (94” x 180”). Helios is an exceptionally fast, quiet, and efficient large-format screen exposure system, with an ergonomic design that’s extremely user-friendly.
