| Precision Controls Tech Fitt® Steam Solutions |
This system uses a design that allows any of the trapping modules to be taken out to be maintained, if necessary, without the need to break pipe or remove the trap body from the system. All models are warranted for the life of the unit on which they serve for steam systems using up to 125 lbs of steam pressure. Systems using higher pressures, up to 175 lbs, are warranted on a case by case basis.

We've summarized the different types of traps below, but for more detailed information be sure to view Tech Fitt's® brochure, visit their website (http://www.tech-fitt.com) or contact us.
- Labyrinthine Modular Traps
This design uses a chamber technology where the condensate enters the module into a chamber, creating turbulence. The higher the pressure the more chambers are needed. This turbulence causes a back-up of condensate, which acts as a barrier, keeping the steam where it belongs. The condensate leaves the module in a continuous flow at a constant temperature, returning to the boiler. This type of trapping system is used where the condensate loads are fairly constant or vary to a moderate degree.
- STR Retrofit (Picture) (Specs Sheet): Used primarily as a retrofit of thermostatic angle type traps where the original unit’s "guts" and seat are removed and replaced, re-using the trap’s body. The module is protected by a stainless steal mesh screen which is easily accessed for cleaning, if necessary. These retrofit kits replace traps in heating units with a smaller range of condensate loads such as cast-iron radiators, fin-tube radiation, fan coils, unit heaters, reheat booster coils, and univents using 10% or less outside air.
- STL Replacement Trap (Picture) (Specs Sheet): Used to replace float and thermostatic traps and bucket traps on steam systems using 15 lbs and less steam pressure. These traps come with a Y-strainer with a stainless steel mesh screen and blow down valve on the Y-strainer. These can be installed on some air handling units using 10% or less outside air where the control valve stays closed when the fan is off and any face and bypass dampers work in conjunction with the control valve. These are also used as drip and end-of-line traps on steam headers and distribution lines, as well as, heat exchangers and absorption chillers with control valves.
- STH Replacement Trap (Picture) (Specs Sheet): Used to replace float and thermostatic traps and bucket traps on steam systems using more than15 lbs of steam pressure. These traps come with a Y-strainer with a stainless steel mesh screen and blow down valve on the Y-strainer. These are installed as drip and end-of-line traps on steam headers and distribution lines.
- Thermodynamic Disc Traps
This design uses a module where a disc is encased inside of it. The module can be taken apart to be cleaned, if necessary. This disc opens and closes based on condensate build-up and temperature change to consistently remove condensate, returning it to the boiler at a constant temperature. This design is used for a wider range of condensate loads.
- TDR Retrofit Trap (Specs Sheet): Used primarily as a retrofit of thermostatic angle type traps where the original unit’s "guts" and seat are removed and replaced, re-using the trap’s body. The module is protected by a stainless steal mesh screen which is easily accessed for cleaning, if necessary. These retrofit kits replace traps in heating units with a wider range of condensate loads such as fan coils and unit heaters near large outside doors where temperatures can vary. These are also used in univents using more than 10% outside air and/or where the control valve can go wide open when the fan is off, and/or where face and bypass dampers are used independent of the control valve.
- Modular Thermodynamic Float Traps
This design uses a heavy base with a module and float that sits on top, where the cover can be removed to clean a stainless screen if necessary. The heavy base absorbs any shock caused by hydro-knocking, preventing any damaging effects. There are no mechanical linkage or bellows used. It is designed to remove a very wide range of condensate loads, on high and low steam pressure systems.
- M Float Trap (Picture) (Specs Sheet): Used primarily as a replacement for the float and thermostatic traps and bucket traps found on large air handlers, especially those taking in 100% outside air, or those where the control valve can go wide open and face & bypass dampers take over controlling the temperature of supply air. These are also used on main distribution lines, as drip or end of line traps, where varying loads of condensate are found.
- L Float Trap (Picture) (Specs Sheet): Used primarily as a replacement for the float and thermostatic and bucket traps on small air handlers, humidifiers, drip and end of line traps. These are smaller than the M Float traps and therefore handle smaller amounts of condensate.
