Designing Thermal Solutions for Photovoltaic Processing Equipment Watlow’s thermal solutions start at the beginning with silicon ingot production and are found all the way through manufacturing and test of photovoltaic cells and modules. Watlow® products can be found in a variety of thin-film processes including those used to produce a-Si, CdTe and CIGS solar modules. As an extension of your internal engineering resources Watlow can provide engineering teams dedicated to solving your most complex thermal problems. The rapid evolution of photovoltaic tool design and manufacturing processes combined...

Radiant Heater Panels Watlow’s custom radiant heater panels can be used to provide uniform heat to both single piece and web style substrates. With custom panel sizes up to 47 in. (1.2 m) x 86 in. (2.2 m) and a choice of heating technologies to choose from, these radiant panels can be designed to meet your thermal processing needs. Custom engineered panels are fitted with appropriate heat shielding to maximize process efficiency by providing more heat where you need it and less where you do not. The entire package is then assembled to a structural frame that can be easily mounted into your processing...

Thick Film Heaters Watlow layers thick film resistor and dielectric materials on stainless steel to produce high performance industrial heaters. The thick film heaters provide very fast temperature response and uniformity on a low-profile heater. Thick film heaters are ideal for applications where space is limited, where conventional heaters can not be used, when heat output needs to vary across the surface or in ultra-clean or aggressive chemical applications. Watlow’s large flat panel heaters were developed to address customers’ growing processing requirements. These large panel thick film...
