Alphacool 15377 δοχείο εξισορρόπησης

The Alphacool ES reservoir for DDC pumps is a compact expansion tank developed for 1U server racks. Its integrated pump top accepts DDC (Laing-style) pumps and supports high pump performance while the reservoir volume is sufficient for a liquid cooling loop in a 1U chassis. The housing is finished in black and the small footprint allows flexible placement in tight server environments.

Advantages

The reservoir provides seven G1/4" threaded ports (1x OUT, 6x IN) distributed on all sides to enable multiple loop layouts and simplified filling. Mounting holes on the bottom and sides match standard 2.5" drive mounting positions, and an included adhesive Velcro pad offers an alternative quick-attach option. A double-nipple fitting is included to mount the reservoir directly to compatible Alphacool NexXxoS radiators, saving hose length and installation space.

Suitable for

• 1U server racks and other low-profile chassis
• Custom water-cooling loops using DDC (Laing-style) pumps
• Compact systems requiring multiple G1/4" connection options

How to use

Install a compatible DDC pump by placing the pump into the integrated pump top with the supplied O-ring and secure it with four screws. Use the G1/4" ports for inlet, outlet and filling: one top inlet is intended for filling while the second top inlet helps vent air during the process. Mount the reservoir into a 2.5" drive bay using the side or bottom mounting holes, attach with the included Velcro pad where mounting holes are not available, or screw the reservoir directly to a compatible Alphacool NexXxoS radiator using the supplied double nipple fitting.

Recommendations

Ensure the installed DDC pump uses the original Laing-style housing; alternative pump housings may be larger and not fit the integrated pump top. During filling, open the venting inlet to allow air to escape and verify all G1/4" fittings are tightened to prevent leaks.
