Start every day off on the right foot
After a restful, cozy night’s sleep, wouldn’t it feel great to step onto a nice, warm surface? We think so. With hydronic radiant floor heating, specially-designed pipes circulate a customized fluid throughout the room (and building), keeping the floor – and your feet – at a constant, comfortable temperature.
How can we help create efficiencies from the ground up?
These highly-flexible, multi-layer pipes are made by securely bonding an inner layer of material to an outer layer of polyethylene of raised temperature resistance (PE-RT).
Used in three- or five-layer floor heating pipes, DOWLEX™ 2344 PE-RT Resin builds on the traditional strengths of polyethylene to deliver a little something extra:
- Long-term hydrostatic strength at high temperatures with no need for cross-linking
- Excellent toughness and flexibility (even at low temperatures) for durable, extremely leak-resistant performance
- Exceptional surface smoothness for improved flow with reduced pressure loss and deposit/sediment formation
- Corrosion and hard water scaling resistance for added protection of aluminum or EVOH layers
- Potential real-time installation savings
This proven, highly respected solution also meets or exceeds key performance standards:
- North America
- Plastics Pipe Institute (PPI) TR-4 listing of 630 psi HDB at 180°F (82°C)
- ASTM F2623 and ISO 10508 (classes 1, 2, 4, and 5) non-potable heating pipe requirements
- Europe
- ISO 9080 for long-term hydrostatic strength
- ISO 10508 for hot water applications (all classes)
- ISO 2578 for prolonged heat exposure
- ASTM F2023 and NSF P171 protocols for chlorine resistance
Plus, existing cross-linked polyethylene (PEX) pipe equipment can be easily converted to produce pipe from DOWLEX™ 2344 PE-RT Resin.
How can we help keep the comfort flowing?
As in-floor heating systems have advanced, the liquid used to spread warmth throughout them has evolved from plain water to optimized formulations of water and glycol.
DOWFROST™ HD Propylene Glycol-based Heat Transfer Fluid answers the unique challenges of radiant floor heating by helping prevent:
- Freeze-up and/or bursting caused by prolonged power loss and exposure to low temperatures
- Corrosion, scaling, and sediment that can
- Cause leakage and/or system failure
- Reduce efficiency/restrict flow
- Damage pipes, pumps, and other components
- Increase energy costs
- Decrease service life
DOWFROST™ HD fluid offers excellent heating performance ‒ plus peace of mind ‒ to system designers, installers, businesses, and homeowners with:
- Cold temperature protection down to
- -60°F (-51°C) against freezing
(depending on concentration)
- -60°F (-51°C) against freezing
- Corrosion inhibitors, pH stabilizers, and other additives designed to enhance system performance and service life
- Non-toxic propylene glycol to prevent accidental contamination of drinking water
Other products used with hydronic/radiant floor heating systems include:
- BYNEL™ Adhesive Resins (PE-aluminum adhesive)
- DOWTHERM™ Heat Transfer Fluids
- DOWFROST™ Inhibited Glycol Fluids/Coolants
- DOWCAL™ Inhibited Glycol Fluids/Coolants
