Hydrolevel VXT-120 Water Feeder

The Hydrolevel VXT-120 Water Feeder (Part Number 45-122) is a heavy-duty 120Vac automatic water feeder engineered for commercial and residential steam boiler systems. Designed for universal compatibility, this unit integrates seamlessly with both probe-type and float-type low water cut-offs (LWCO) to maintain precise water lines without manual intervention. A built-in programmable delay before feed (adjustable from 30 seconds to 10 minutes) ensures that condensate has sufficient time to return to the boiler, preventing overfilling and thermal shock. The digital feed counter provides technicians with a clear record of make-up water volume, which is critical for diagnosing steam system leaks and protecting the boiler block from mineral scale buildup. With programmable feed settings ranging from 1 to 5 gallons or a standard LWCO match, the 45-122 model offers the granular control required to optimize steam heating system performance and longevity.

• Universal Compatibility: Works with virtually all 120V probe or float-style low water cut-offs.
• Flood Protection: Features a lock-out flood protection safety that stops feeding after two consecutive cycles to prevent basement flooding.
• System Diagnostics: The integrated digital water meter helps identify hidden leaks by tracking exactly how much water is being added.
• Flexible Installation: Includes a manual feed button for system testing and a rotating housing for easier piping and wiring in tight mechanical rooms.
• Underfeed Protection: Automatically initiates a second feed cycle if the initial amount does not satisfy the LWCO.

• Can I use this with a 24V control circuit? No, the VXT-120 is specifically for 120V systems; for 24V applications, you must use the VXT-24 model.
• How do I prevent the boiler from overfilling during the return cycle? Adjust the programmable delay via the internal dip switches to allow more time for condensate return.
• Does the counter reset if the power goes out? No, the VXT-120 features non-volatile memory to preserve the feed counter data during power interruptions.
