The Delta Current Control fan controller kit monitors the coolant temperature and adjusts the speed of the fan in order to keep the monitored temperature constant. As a result, there is no temperature cycling, a reduction in both average current draw and fan noise, and incredibly accurate temperature control. This is particularly useful on modern OBDII systems, as the temperature can be set just above the cold-mode algorithm of the computer, negating the need to reprogram the system in order to attain a lower operating temperature. The controller is completely transparent, requiring no other modifications.

Unlike the majority of aftermarket products, the Delta control system is designed and manufactured with reliability in mind. Not only are die temperatures kept low to insure long life, a multitude of safety and reliability features, some not even available on OEM products are employed:

Over current, short circuit and over / under voltage protection limit the inrush current to the load, providing protection for not only the controller, but to the fan and to the remainder of the electrical system as well.

Over temperature monitoring provides multi-step protection. Under moderately severe conditions, output current is progressively reduced, causing only a subtle rise in engine temperature. Where more severe conditions are introduced, the control unit will begin to cycle in a fashion similar to a standard controller. This provides not only protection for the controller but also acts as a problem indicator to the driver as cooling noise will substantially increase. Finally, if conditions prove to be too severe for safe operation, the controller will shut itself off.

For added safety, a UL-94-0 self-extinguishing PC board, encapsulated within a high-grade epoxy, also UL-94-0 rated, is housed in an aircraft grade 5052 hard-anodized aluminum fire resistant housing.

High current 3M connectors are utilized in our 10-gauge copper, multi-strand wiring loom. The loom comprises crosslinked polyethylene insulating material, which is abrasion resistant, specified over a -51°C to +125°C temperature range and meets both Ford (M1L-85A) and Chrysler (MS-5919) specifications as well as Society of Automotive Engineer’s SAE J-1128 specification for high temperature engine compartment applications. This is not the case for the majority of aftermarket components.

In lieu of the bigger is better method of temperature sensor retainment, our low mass temperature sensor utilizes a high friction housing and multi-strand, high flex wiring in order to provide a probe that doesn't deform your radiator and is self retaining for ease of placement. Accuracy is +/- 3° F.
