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.
