Custom Product for Tutco Farnam
ChemTec has worked closely with Tutco–Farnam Custom Products to provide flow switches that meet the demands of their clients based on specific applications.
Tutco-Farnam Custom Products was contacted by pharmaceutical equipment builder who planned on using the TPC1500, but requested several custom features, which Tutco-Farnam Custom Products commonly does toprovide customers the best solution for their specific application. One of the modifications requested was to change the flow switch material from brass to stainless steel, as they wanted all stainless steel components for the air flow path. ChemTec was contacted to determine the feasibility of this. As discussion ensued about this, ChemTec offered up several suggestions.
The final configuration:
WAS: pipe nipple —-coupling—flow switch—coupling—-nipple—-heater
IS: pipe nipple—flow switch—nipple—heater
1) Simplify installation by providing female threads instead of the former male thread. This reduced the components required to plumb the flow switch into the system.
2) The reed switch is now integrated into a single stainless steel body. The new design provides better protection for the reed switch. Whereas the reed switch was formerly brazed to the OD of a brass pipe, it is now potted directly into the body. In addition, it eliminates the requirement for a brazing operation for ChemTec, easing manufacturability and reducing the opportunity of any damage to the reed switch during assembly.
From our collaboration, we now have a flow switch which has been improved beyond just the requirement for all stainless steel construction. Tutco-Farnam Custom Products receives a flow switch which has been improved in several aspects with a minimal increase in cost. This switch has now been adopted as a standard component in all of Tutco-Farnam Custom Product’s TPC1500s.”

Excess Flow Valves detected leaks in some of the braided flexible hoses that were being used and shut the system down instantly.
First, I must thank you again for all of your information, assistance and patience you showed us when we were investigating these valves, going those few extra yards with my customer has helped us to secure more projects with him.
During my meeting today I enquired about the EFV excess flow valves. My customer and the operators were very impressed with the quality of the product and ease of operation, they have been installed with no hassles or setbacks and no further calibration was required on the system. In their words “the installation could not have gone better”.
In fact the valves detected leaks in some of the braided flexible hoses that were being used and shut the system down instantly.
As expected, once the gas line was vented the valves reset themselves perfectly. My customer could not be happier.
We have added these valves to our product lists and brochures and will be added to our website which will be on-line very soon, we will market them where possible. Hopefully we will continue to sell more of these.
