HydroNex | Hydronic Control Systems

HydroNex® panels are built to do more, for less money, faster. We pre-engineer and mass produce them on a new assembly line as a modern, radiant appliance. They're dependable; built for easy installation and fast service. Link them together or use them stand-alone. All 35 standard models come with powder coated metal enclosures and a lower price point than any comparable product.

HydroNex Panel Installation

Primary Series Panels

Primary loop panels manage high temperature circulation from your boiler with automatic or manual fill value options with 1-1/4" copper mains with pump isolation flanges, air remover and a temperature/pressure gauge. All Primary Panels are Rail Mounted and come equipped with Watts, B&G or Taco circulators.

Zone Series Panels

Zone panels install in or close to the zones they heat. All components are enclosed in a thin-profile steel lockable cabinet that can be surface mounted or installed between wall studs. Zone Series is available with Watts Radiant pumps and stainless steel manifolds in three options:

  • Zone Basic with or without actuators. These panels require a zone pump which is typically supplied by a D series panel.
  • Zone Pump manifolds with built in pump, with or without actuators.
  • Zone Mix manifold with built in pump, thermostatic mix valve, with or without actuators.

Distribution Series Panels

Distribution panels circulate water to a variety of heat distribution options by way of 1-1/4" mains, pump isolation flanges and easy serviceability. All Distribution Series Panels are Rail Mounted and can be equipped with Watts, B&G or Taco circulators. Your options include.

  • D-Direct Pump panels circulate water from your Primary loop to remote manifolds. These panels are typically used for higher temperature applications like radiators, fan coils, staple up, underfloor radiant, kick space heaters or indirect water heaters.
  • D-Mix panels use a thermostatic mix valve and up to three pumps to deliver an adjustable temperature to remote manifolds. Each pump is pre-wired to a built-in zone control.
  • D-VIP panels use an outdoor reset control to vary water temperatures as weather conditions change. They provide independent control over one to five remote zones.
