We Ask the Right Questions

We use our experience as former Carrier salesmen to dig deeper to help you avoid unexpected problems. We often ask “have you thought about this” type questions to make sure your coil is designed correctly for your project. One part of our job is to make you look good!

 We Are the 39 Series Experts

From 39A to 39M to 39W, and everything in between, we know the specs and we know the sizes for coils to fit these units.  From old replacements to new applications, SFI will make your job easier.

 

 We Are Your Resource for Plan & Spec Bids

SFI knows how to help you bid a job thoroughly and accurately.  If you have a coil project you need to price, send SFI your schedule and specs.  Similarly, if your engineer needs 1 to 100 coils selected, let SFI do it for you!  In either case, use your time to design and sell the big stuff.  Let SFI sell you the coils.

 We Take Pride in Going the Extra Mile

Customer service means paying attention to ALL the details of your job. We know that you don’t have time for nuisance calls from your customers. So we make sure the coil is tagged correctly and the shipment is marked accurately. We provide scheduling updates and shipping information when you need it. And you can be sure that no matter who you talk to when you call SFI, you will encounter competent, friendly assistance. We treat people just like we want to be treated ourselves.

The greater the distance a fluid travels in the coil the more it passes and the lower the flow rate required. Fluid inside a half circuit coil will travel twice as far as the full circuit coil. The longer the fluid is inside the coil, the longer the heat transfer or higer capacity. There is always a trade off as the water pressure drop will be higher as well.
