THE MrPEX RADIANT PANEL
SYSTEM
The MrPEX® Radiant Panel Heating System is
a complete radiant heat distribution system,
consisting of tubing, fittings, manifolds, controls and
accessories that are matched for high performance
and reliability over many years of service. When
used together, these components provide trouble
free installation and long-term reliability. The MrPEX®
tubing and fittings meet current national standards
of performance and dimensional tolerances.
Products from other manufacturers may deviate
from these standards. Therefore, it is recommended,
as a best course, to only use MrPEX® radiant heating
pipe and fittings components as a complete system.
WHO IS MrPEX?
MrPEX®—Tomas Lenman—started at Wirsbo
Bruks AB in Sweden as a development engineer
in 1971, developing the very first PEX process
ever invented. He developed many Standard
Specifications for PEX Tubing in Europe and
Australia. MrPEX® wrote the ASTM F 876/877
for PEX Tubing during 1982–84. In 1982 he co-
authored the book “Water and Pipes”. He founded
and managed Wirsbo Company (USA) 1984–1992
and continued consulting for this group until 1996.
He authored the Canadian CSA B137.5 standard
for PEX Tubing in 1989.
MrPEX® managed the successful start-up of Roth
Industries PEX Tubing Division 1997–2001 after
which he started his own radiant floor heating
supply company: MrPEX® Systems using PEX
Tubing with exclusive distribution in North America
for LK PEX AB in Sweden. The unique production
process is invented by Mr. Lennart Aagren of
Sweden, previously manager of Uponor Innovation
AB for many years, and his second innovation of a
PEX Tubing manufacturing process.
