Radiant Heat Tube	Onix™	click to enlarge Onix is the fastest, friendliest, and safest radiant heat tube you can specify or install. It installs with less labor and takes jobsite abuse better than any other radiant tubing. Onix is Aramid reinforced EPDM with an aluminum oxygen barrier. Onix is the product that can be installed with lifelong confidence in blazing heat and sunlight, or in Arctic frost and shadows. Used for commercial snowmelting, space heating, residential staple-up and supply/return lines, you'll find Onix installed in thousands of quality projects every year. Onix is ICC listed.
PEX Tubing	RadiantPEX™	click to enlarge The cross-linked molecular structure of RadiantPEX offers toughness, flexibility and lasting durability. RadiantPEX is corrosion resistant and virtually maintenance free. This radiant tube combines all of the traditional advantages of plastic PEX tubing, but with an EVOH oxygen barrier. This barrier provides added protection against corrosion for ferrous components in a heating system. RadiantPEX is manufactured to meet the American Standard Testing Method for cross-linked Polyethylene Tubing (ASTM F 876) and all sizes are made to the Standard Dimension Ratio for plastic pipes, SDR 9. RadiantPEX is ICC listed.
Composite Pipe	RadiantPEX-AL	click to enlarge RadiantPEX-AL is a composite pipe engineered for radiant floor heating. We call it ALEX Pipe. It's proven, long lasting and maintenance-free. Installers like it because it's lightweight, durable and can be shaped to fit any jobsite. The aluminum layer protects boiler systems against corrosion and it has superior temperature and pressure ratings. ALEX Pipe is manufactured to American Standard Testing Methods for composite radiant pipe and fittings (ASTM F-1281). Included are requirements and test methods for materials, workmanship, dimensions, environmental stress cracking, sustained hydrostatic pressure strength, thermo-cycling resistance and bend strength among other tests. RadiantPEX-AL meets or exceeds these specifications.
Hydronex Panels - Family	Hydronex™	click to enlarge 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 130 standard models come with powder coated metal enclosures and a lower price point than any comparable product. Hydronex panels come in three general types.
P-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 Watts, B&G or Taco circulators.
D-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 D Series Panels are Rail Mounted and can be equipped with Watts, B&G or Taco circulators.
Z-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.
