    Manufacturer's Part Number:

    Derale makes mounting and controlling your electric cooling fan easy with a variety of controllers, thermostats, and mounting accessories to work with your vehicles cooling system. Derale is dedicated to providing the highest quality products and everyday value in the most complete performance cooling line in the industry.

    16728 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Works as is supposed to for my project I modified the cooling system in my 1978 Toyota pickup with electric fans replacing the mechanical belt driven fan-clutch/fan. The Derale thermostat switch controls just one of the 2 smaller fans shown in the photo. It is the small fan on the top above the other small fan. I refer to it as "Fan 3". I use a toggle switch located on the dashboard that controls whether or not Fan 3 is in service. When Fan 3 is in service, the Derale thermostat switch always controls the cycling of Fan 3. Because of my personal requirements there is a total of 4 relays for controlling Fan 3. One of the relays is just an isolation relay to prevent any of the other relays from "latching". The Derale thermostat switch powers the 'system' of relays, which, 1- draws less amps through the thermostat switch then Fan 3 draws, and, 2- it is necessary for several relays in the design of my fan switching system to meet the operational requirements. Also, the Derale thermostat switch should last longer haveing a longer total lifetime of cycling with the lower amperage demand on it. The reason I have so many relays to control one small fan is because when the fan is in service, depending on ignition switch position, it will either be running on the main starting battery and charge system when the ignition switch is on, or, when the ignition switch is off Fan 3, when it is in service, is always controlled by the Derale thermostat switch, and is powered by a deep-cycle auxiliary battery, so there won't be any draining of the main starting battery whenever the ignition switch is off.
