Product Highlights

We are known for our very flexible and durable MrPEX Barrier Pipe for Radiant and Snowmelt Systems, and we now offer a complete PEXa plumbing system with the same great product, offering some… real advantages as compared to conventional copper pipe systems.

The MrPEX POTABLE PEXa tubing is offered in red, white & blue, and in coils or sticks, with complete accessories and tools! The fitting system utilizes Lead Free Brass F1807 and PPSU F2159 profile together with a stainless steel PEX press sleeve.

MrPEX Stainless Steel manifolds achieve the highest level of long term corrosion resistance by using a bright annealed high-grade stainless steel with high nickel content. This creates a stable material structure with low levels of ferrite and magnetism. To eliminate the possibility of contact corrosion, all fittings connected to the manifold are nickel-plated.

The manifolds are fully assembled, ready for mounting, the supply side feature adjustable flow-meters for flows up to 1.45 gpm per loop, and the return side has balancing on/off valves, in accordance with DIN EN 1264-4. The adjustable flow-meter allows for a positive shut-off and the manual plastic cap on the return valve can be removed to accommodate a valve actuator. The return balancing valve disc is designed to enable exact adjustments of small flows while still being able to handle large flows with minimal resistance. The combined branch Cv value is 1.64 gpm and the manifold body accommodates flows up to 14 gpm.

Retrofit system for existing applications

RetroPanel is a perfect retrofit product for applications where comfort, efficiency, system height, and performance is key. It uses the combination of metal on the surface, with high thermal conductivity and built-in insulation underneath, to maximize the heat output at low water temperatures. The metal surface also promotes an even temperature distribution across the floor, minimizing cold spots. The low thermal mass allows for a quick response to changing load requirements. RetroPanel is unmatched in its ability to optimize system efficiency.

The RetroPanel is a floating system and the panels are easily installed by snapping them together to form a uniform layer over top of either a concrete slab or wood sub-floor. The panels are arranged with the tubing channels (grooves) of the RetroPanels. The metal tubing shields and return panel coves are then attached over the tubing. Finally, the finished floor is then installed directly over the RetroPanel surface to complete the installation.

Just a few of RetroPanel’s benefits:

• Snaps together – labor saving
• 1/2″ tubing – longer loops, fewer circuits
• Tubing is protected against damage
• Pre-insulated and low profile (3/4″) – great for retrofits
• Highly conductive surface – high heat output and even temperature distribution
• Water-resistant – great for basements
• Easy to cut if necessary to fit tight spaces and around obstructions
• Low thermal mass – quick output response

MrPEX Systems is introducing a new style extruded aluminum heat transfer plate for 3/8” or ½” PEX tubing in the same plate. DuoTrack is 48” long x 3.75” wide with pre-punched holes featuring a double grove for two sizes of PEX tubing. This reduces inventory, space and cost.

DuoTrack plates are low mass and have a faster response time, higher output, and lower water temperatures requirement as compared to joist heating without plates. Give it a try next time you have a suspended application.
