Energy-saving Free Float Steam TrapFeatures
The TLV Free Float SS1 Steam Trap Series is the world’s #1 energy
saving steam trap, reducing steam use and CO2 emissions.
● Precision-ground Spherical Float and Three-point Seating
Unique three-point seating and precision-ground float free float typesteam trap continuously discharges condensate without
accumulation. The spherical float provides infinite sealing surfaces
for high durability and long product life. The float and three-point
seating provide tight sealing.

ground float● Stainless Steel Components Ensure High Durability
The body and the valve seat use corrosion and rust-resistant
stainless steel, thus maintaining the initial performance for a longtime.
● Built-in Bimetal Automatic Air Vent
The built-in air vent responds to temperature and promptly exhausts
initial air in the piping, thus making it possible to start operating thetrap immediately after the supply of steam.

● Specially Designed Insulating CoverNo insulation work is required because the SS1 Series can beequipped with specially designed optional insulating covers,
providing effective insulation.

Basic Concept or Summary
Overview
Steam is often used incleaning, hospitals, food/rubber
factories and other industries,
and the boiler fuel cost togenerate this steam has a lot to
do with production costs.
Discharging condensate isessential when using steam,and steam traps are thedevices for that job. Boiler fueluse is influenced in a large partby steam trap selection.
The SS1 Series has realized
tight sealing, long service life
and the features shown above
to become the world's #1
energy-saving steam trap.

SS1 Series

Operation
1. At start-up the system is cold,causing the bimetal air vent strip
to hold the float off of the valve
seat. This allows rapid dischargeof air and cold condensate whensteam is first supplied to thesystem.
2. If the temperature of thecondensate rises above 90 ºC(194 ºF), the bimetal air vent
strip allows the valve to close.
The float lifts off the valve seatas condensate levels rise,discharging hot condensate.
3. When the condensate flow rate
decreases, the lowering level ofcondensate causes the float tofall, resting on the valve seat. A
water seal over the valve seat
prevents steam loss. The
bimetal is still curved, notaffecting the float movement. As
the condensate flow ratechanges, steps 2 and 3 will
repeat in cycles.

Effects or Remarks

F-42

Up until now, the most commonly used steam traps are disc type, but as the graph below shows, even anew disc trap loses approximately 1 kg/h of steam. Additionally, while in use, each year the amount ofsteam loss increases. In comparison, the SS1 Series loses less than 0.1 kg/h, and keeps the loss at thatlevel over an extended period.
Therefore, the steam loss from 100 properly operating steam traps is 360 tons per year, or approximately
1.44 million yen. The equivalent amount of CO2 emissions saved is approximately 70 t-CO2/year (operating
4,000 hours/year, with steam at 4,000 yen/ton). In reality there is also steam leakage from failed traps thatmakes the effectiveness even greater.
As part of the Environmental Technology Verification (ETV) program, Japan's Ministry of the Environment
has verified that the SS1 series minimizes steam loss associated with condensate discharge.
