Vapor Trap
Overview
FTS Vapor traps are mechanicallyrefrigerated cold traps that protect
expensive vacuum pumps from harmful
vapors which can shorten their life. The
harmful vapors constitute any
condensable gases such as water vapor,
which, when allowed into the vacuum pump
oil, cause it to break down. This results in
decreased lubrication and can eventually
cause failure of the pump.

Maximum efficiency for vacuum trapping
vapor to -90°C, without LN2 or dry ice
Available with low temperatures to -50°C or -90°C
Reduces the need for liquid nitrogen

In addition, Vapor Traps eliminate the
expense and potential hazards associated
with the refilling and monitoring of LN2 or
dry ice traps.
FTS Vapor Traps consist of a well-insulated
stainless steel chamber that is cooled by
direct expansion of refrigerant in
refrigeration lines that are bonded directly to
the outside of the chamber walls. This
method of refrigeration is a highly efficient
and energy-saving means of heat removal.
Vapor Traps are available with operating
temperatures of -50°C or -90°C.
Vapors enter the chamber through a port in
the vacuum top plate. While the vapors circulate in the chamber, they strike the sides
and are frozen-out on the low
temperature of the chamber wall. The
system will trap all condensable vapors that
have freezing points higher than the operating temperature of the Vapor Trap.
Non-condensable vapors and gases are
evacuated through a second port in the lid
by the vacuum pump. Traps are rated to
accommodate vacuum pump flow rates of
up to 250 liters per minute. (9scfm)
