Internal Water Supply Freeze Protection
Retro-Line is an internal self-regulating heat tracing system designed to
provide freeze protectiwon of existing water supply and uid pipes without
their removal. Insulation and an optional thermostat can be used to optimize
energy eciency.
CSA/NSF Approved
Retro-Line is the only cCSAus NSF/ANSI 61 Drinking Water approved, inter-
nal self-regulating P and X factory nished freeze protection system available
on the market.
Complete System
The Retro-Line system is supplied in a predetermined length with all neces-
sary components for a complete system. For polyethylene pipe applications
Retro-Line is supplied with a compression tting for connection to the pipe.
Multiple Interfacing
An I.D. controlled tee tting for polyethylene pipe is supplied standard with the
Retro-Line system. Retro-Line can also be ordered with a CTS controlled tee
or a threaded male adapter for easy interfacing to pipe such as ABS, PVC,
PEX, copper, galvanized and steel.
Requirements
Retro-Line orders require the length of heating cable and pipe size for
polyethylene installations or male adapter thread size for other pipe
installations. System lengths are 120 volt up to 230 feet and 240 volt up to
550 feet. Minimum pipe size required is 3/4 inch ID.
Fully Servicable
Short Retro-Lines can simply be pushed into the pipe while longer systems
may be pulled in using a sh tape. The downward end of the cable does not
need to be internally fastened, as it will not re-coil, which is extremely important
as it renders the system fully serviceable. The system can be removed and
replaced should it become necessary.
Easy Installation
Heat-Line developed a unique, patented dispensing system called “Retro-
Reel” to protect the heating cable and ttings from mechanical injury while the
product is deployed into the pipe with absolute ease. It is not unusual to push
systems in up to 150 feet and sometimes more.
Versatile Application
Retro-Line can be used in a variety of applications, including metal and plastic
water supply, sump pump lines and pressurized or high volume drain pipes.
