The ULTITUBE D5 200 expansion tank with D5 PWM pump from Aqua Computer is a high-quality solution for water cooling in computer systems. Equipped with a robust borosilicate glass tube, this expansion tank offers superior scratch resistance and chemical durability compared to conventional acrylic models. The glass tube has an outer diameter of 65 mm and is connected at both ends with black anodized aluminum rings that do not come into contact with the cooling medium. The tank features an integrated stainless steel filter element that acts as both a particle filter and a bubble separator. The D5 PWM pump, mounted directly at the bottom of the tank, allows for precise control of pump performance via a PWM signal and additionally provides a tachometer signal for monitoring pump function. This combination of functionality and high-quality craftsmanship makes the ULTITUBE D5 200 an ideal choice for demanding water cooling systems.
