Delta Current Control Module
Looking to replace your belt driven engine fan with an electric fan in order to free up some horsepower? Do not underestimate the importance of having your electric fans properly wired and controlled. A wonderful product that will drastically simplify the process is the Delta Current Control Module.
I recently replaced a 7-blade thermal clutch fan on my 1966 Malibu with a dual 13″ Derale setup. The dual fans draw a massive 50 amps when turned on, but move an impressive 4000 CFM of air. Your car does not always need 4000 CFM of airflow in fact often it will need little to no fan assistance to stay within operating temperature. This is where a fan controller comes into play.
A typical electric fan install consists of a thermal switch that operates a relay. The relay is in turn connected to the fan. Often the thermal switch will turn the fan on at one temperature, for example 210 degrees and off at another, say 175 degrees. The problem with this sort of setup is that your engine temperature is constantly fluctuating.
The Delta Current Control Module operates by varying fan speed to maintain engine temperature at a desired level. The unit is a full, self-contained system. It takes the place of a thermal switch, relay, fuse, manual override switch, air conditioning switch, etc. [Read my article on the Install of a DCC unit in my 1966 Chevelle.]
I have been running a DCC unit on my car for the past week and once car is warmed up the temperature gauge rarely moves at all. This includes a 100-mile freeway drive, multiple drive-thru lines, a trip to the drag strip at LACR and a 30-minute driveway idle. The switch from mechanical to electric fans has also freed up a noticeable amount of power.
Features:
- Turns on fan only when needed
- 100% Self Contained, compact Unit
- Adjustable Target Temperature (148, 158, 166, 173, 180, 187, 194, 202, 212)
- Maintains engine Temperature within a tight heat range
- Has provision for A/C activation and use with under drive pulleys
- Choice of two types of thermal probe
- Frees up horsepower (verified by my faster quarter miles times)
- Can also be used to control an electric water pump.
Verdict:
A no headaches solution to electric fan control. The DCC unit is an elegant solution that works as advertised.

The paperwork that comes with the unit has the number (408) 379.8951 listed to find an authorized service center, you could give it a ring and see where it leads.

Email me at home and I will get his number if that doesnt get you there. Brian was very helpful. I ordered two controllers on Friday a couple weeks ago, and it arrived just as he promised.

Thanks, Brian makes a great product. I plan to get another one for my 1990 Ford Mustang GT project.

I ordered a DC controller on 7/10/06. I still have not received it nor have they answered my emails when emailing dc control. I know this blog is old but wondering if anyone has the phone number for them?
Thank you in advance - my Camaro is out of service until it arrives.

Does anyone have the number to contact anyone at Delta Fan Controllers?

Well I have received a few e-mails reguarding my post. Yes I did receive the module and no it doesn’t work. Don’t buy it! I don’t even think he sending them out anymore. Just taking peoples money. He doesn’t answer e-mails either. That phone # 408-379-8951 is his or was his? I called him on it back in Oct. 06 and talked him. I complained that it was taking too long for the order and offered a refund but I choose to wait. He did check his e-mail while I was on the phone and said oh there’s the e-mails. I install the unit which looks very nice and it was swicthing on and off which resulted in over heating then cooling then over heating, cooling ect. Don’t buy it save your money.

After writing the last post he answered my email and then called me. Hes a nice guy but seems to be not that good at communication. He told me to try a couple test, so tomorrow I’ll see if it works. I’ll update later with the results.

I spoke to brian a week ago before his website changed to the blank page. He is very good at discussing any issues you may have, however getting in touch with him is kinda difficult. I am trying to stay patient since I sent payent to him and need more items. I ll let you guys know whats going on when I reach him. Car is out for now since temps here are 110 in the shade
John
p.s. be patient he is a one person company

I realize that Brian is going this from home and has typically been a bit slow to deliver in the past, however, they product is still dynamite, and I run one on each of my cars. That is two Chevelles and a 1990 Mustang GT Racecar that are being kept cool by DCC units.

My fan control unit burned up when hooked up to power and ground. I cannot get a hold of Brian and would love to send this unit back to him for testing and replacement.

My unit burned as well. Just about totaled my vehicle. No coverage!! November 8/07

Al, how exactly did it nearly total your vehicle?
I did have an alternator meltdown on my 1964 Chevelle a while back, but as best I can tell, it was not related to the control unit.

Control Over heated wires, fire under hood. Most of the electrical wires were burned beyond use. Repair costs were greater than what the vehicle was worth. I bought back the vehicle and located a donor. Vehicle passed inspection. I am using another controller from another supplier now.

I’m sorry to hear that. Both of my units are still working just fine.

I don’t have time right now to try and link the relevant photos, so I’ll just provide a link to a pdf file

Just for the sake of disclosing what information I do have, the ip address for Matt Rogers traces back to Columbia Missouri, the ip address for Al Goldstone traces to Saskatchewan Regina, Canada, nearly 2000km away.
I find Brian’s explanation, hooking the unit up without the proper fuseable link, then grounding the full charge of the battery to ground, seems like plausible cause for Al Goldsteins trouble.
Just imagine the damage that you would cause if you bolted your positive battery wire to the frame. This is essentially what appears to have occurred in this situation.
The use of a proper fusible link is intended to safeguard against this issue, and in my automotive electrical experience, fusible links work as designed.
I would gladly buy another product from DCC.

Mr. Nagy was aware of the fact that you would see the ip addresses of the poster, he was unaware of the fact that you might post them. As you may have ascertained, Andy considers himself to be quite clever. It wouldn’t be difficult for him to post from another ip address, he could either just dial another number or have a dishonest friend do it, as I’m sure he has plenty of those to choose from.
I guess it’s also possible that Mr. Nagy found this thread exactly one month to the day after the person made the post prior to his, it’s just unlikely that it happened that way.

Brian, I have spent the last three hours reading about your product. There is no doubt you have a superior product to anything else out there on the market. Some people have written some negative things about your customer service and delivery time frame. Knowing these things I STILL want to order your product (FK-35) but I don’t know how to get in touch with you. I will leave my e-mail on here, if I’m allowed, amshutterman@yahoo.com . Please let me know how to get in touch with you. Thanks in advance.

I’ve also sent e-mails recently - waiting on a response (sent to paypal address). Just want to confirm somebody is there before directing funds that way…
THanks!
