If that contact point runs cold, the glass takes a sharp thermal shock. You end up chasing stress fractures after tempering, and throughput tanks while you sort rejects. We built the nip roller preheat module to put heat exactly where it matters, with control that keeps pace with the glass.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>We lean on short-wave infrared (SWIR) quartz emitters for fast, direct energy transfer, tuned to glass emissivity. You get a quick temperature rise without heating the surrounding frame. Each module is specced to your line voltage and footprint, laid out dense and low-profile to fit tight nip zones. Power density is calibrated to give a uniform thermal field across the roller face, so you don’t create hot spots that drive warp and stress. Response is immediate, so temperature tracks glass speed without lag.</p>
