The model #5049 12V DC Igniter was developed over several years and has become one of our flagship products. We are proud of the fact that the model #5049 igniter / Beckett igniter is manufactured in the USA.  The 5049 ignitor is used on many different burners manufactured by various companies.  

Custom Coils builds DC ignitors for several different industries and applications.

Our ignitors can be found in:
Heated pressure washers
Steam cleaning applications
DC HVAC industries.
Tar Buggies

Custom Coils sells several different variations of DC ignitors and we have the ability to custom design ignitors to meet the specific needs of customers that have applications that require special design requirements.  The 5049 is a 12V ignitor, but we have other models that are 24V ignitors.

The #5049 12V DC Igniter is constructed using components and techniques that allow the 12V ignitor to function in harsh environments (-20C to 60C).

The igniter consists of both a primary and a secondary winding. Both windings are constructed using high dielectric tapes and 155C magnet wire. The windings are located within the part such that they are isolated from each other. The combination of these 2 design elements keeps the 12V DC igniter from breaking down during operation. The rest of the components are selected such that they have enough head-room to absorb many of the irregularities that comes from different ignition systems from different manufacturers of small engines.

The key components used in the 12V igniter have been selected because their specifications allow them to be used in elevated operating temperature environments. The entire design and layout maximizes heat dissipation and keeps the DC igniter running as cool as possible. The entire part is then placed in a molded shell and encapsulated in a two part, class F black epoxy resin. The encapsulating epoxy is tough, flexible and resists thermal shock. Once fully cured the epoxy is flame retardant and has a high dielectric strength. This allows the 12V DC Igniter to operate in extreme environments.

The Custom Coils Ignitor (Beckett ignitor) has been designed such that it REQUIRES air flow over the heat sink of the ignitor. It is imperative in all applications that there is a good amount of airflow across the heatsink.

The Custom Coil Igniter, Model #5049 (a.k.a. Beckett 7435, Beckett ignitor, Beckett igniter) is a 12V DC igniter mainly used to light oil burners. Oil burners require a very high voltage spark to initiate a burn cycle. he Custom Coils igniter takes 12V DC from a standard small engine ignition system and converts this 12V DC to a 20KV+ spark. This 20KV+ voltage jumps the spark gap while resting in the combustion chamber of the oil burner. The high voltage spark initiates the combustion of the oil in the burner.

This portable burning solution, a small engine, a burner and an ignitor is used to heat water for many applications. In any industry that requires portable hot water, usually a 12V DC ignitor can be found. In the heated pressure washer industry and the heated steam cleaning industry is where the Custom Coils 12V DC ignitor really shines. In these industries equipment portability is a requirement and many units contain an oil burner and a Custom Coils 12V DC ignitor to generate the hot water required in these industries. Another newer industry of portable hot water heaters for showers and personal hygiene has also popped up and is using 12V Ignitors. All these various industries are being serviced by several name brand oil burner manufacturers; Custom Coils 12V DC Ignitors fits on many of these brands of oil burners.

Most industries that these portable devices go into are harsh environments. These pieces of equipment are subjected to high moisture and high temperature environments. Many are cleaning facilities where harsh chemicals, oils and corrosive fluids are used. That is why the Custom Coils 12V DC Ignitor has been designed to work in harsh environments from -20C to 60C. The internal components of the ignitor are protected by a shell made of Rynite and are completely encapsulated in a high temperature, non-flammable 2-part epoxy. The Custom Coil ignitor, model # 5049 is a rugged ignitor that is versatile and can be used in many different applications.

Custom Coils is the manufacturer of the 5049 Beckett ignitor used on many 12V DC based oil burners.  The Beckett 7435 SKU Beckett ignitor is a re-branded Custom Coils 5049 ignitor.  This Beckett igniter is being used on many DC oil burner models throughout the industry.
