Aquacomputer ULTITUBE D5 100 Reservoir with D5 PWM Pump (34097)

The Aquacomputer ULTITUBE D5 100 Reservoir with D5 PWM Pump is a pump and reservoir combo, with a D5 PWM pump installed in the base. The tube reservoir has a 100 mm borosilicate glass tube and a capacity of approx. 230 ml. Pump speed is set by a PWM signal from a 4-pin fan connector.

Properties

• Pump: D5 PWM, installed in the base
• Capacity: approx. 230 ml
• Ports: 2x G1/4 thread, inlet engraved IN
• Maximum head: 3.7 m at 12 V
• Supply: 8 to 24 V DC, 4-pin Molex plug
• Size: approx. 72 x 72 x 200 mm including pump

Borosilicate glass tube

All reservoirs of the ULTITUBE series, which Aquacomputer also calls expansion tanks, are equipped with a glass tube made of borosilicate. That is in contrast to the Plexiglas, or acrylic glass, often used for tube reservoirs. Aquacomputer says borosilicate offers a very high hardness and scratch resistance, a very low thermal expansion and excellent chemical and thermal resistance. On this reservoir the tube has an outer diameter of 65 mm and a wall thickness of 5 mm.

Metal rings of black anodized aluminum are firmly connected to both ends of the tube, and they do not come into contact with the coolant or any other cooling medium. Base and lid of the tank are made of resistant acetal and screwed to the glass. After unscrewing the lid, you have a large opening available for filling.

Filter and seal

A filter element of fine stainless steel wire mesh is integrated in the bottom of the container. In addition to functioning as a particle filter, the mesh also separates air bubbles from the coolant. It sits in a molded rubber part, so it can be taken out and, for example, rinsed under running tap water. The seal between the upper area of the glass tube and the lid is a molded rubber part as well. It is designed for easy assembly and is therefore held securely positioned while the lid is screwed on.

What the loop needs

Please note that the reservoir is supplied without connections, so order two suitable G1/4 fittings separately. Connect the return line to the port engraved IN and the other line to the remaining port.

Fill it with Double Protect Ultra or water. Coolants with solid micro particles, found in various opaque coolants, must never go in: they damage the D5 pump bearing and may lead to destruction of the borosilicate glass tube.

Notes

• A valid speed signal cannot guarantee an actual flow of coolant.
• The pump must not run dry. Fill the loop first, then deaerate by gently swaying the system or switching the pump off and on several times until no rattling noise is heard.
• In operation the pump's rotor must point up or to the side, never down.
• Screw fittings in with light force only, so the threads in the plastic base part are not damaged.
• To open the lid for filling, hold the glass tube and turn the lid counter-clockwise, taking care not to lose the gasket. Screw it back by hand with moderate force and no tools.
