COMPANY INFORMATION

The MONARCH nozzle is an important component of clean and flawless combustion.

For decades, burner manufacturers, servicemen, wholesalers and tradesmen have chosen the MONARCH nozzle for its precision, efficiency, and long life resistance.

Monarch is participating on committees for the development of European CEN standards, to be adopted in the near future.

DONGAN ENERGY EFFICIENT TP-1 TRANSFORMERS

Dongan’s 41, 42, 43 and 44 series are designed to meet the D.O.E. Energy Efficiency guidelines established under EPACT in 2005. This was sued to establish energy conservation standards for various consumer, commercial and industrial products including certain types of General Purpose Transformers.

This applies to transformers 15kVA and larger and establishes a minimum 97% efficiency level. The following transformers must meet TP-1 standards and therefore no transformer in this group can be manufactured that do not meet these standards.

The following types are excluded from having to meet TP-1:

  • Auto TransformersMotor

  • Drive Isolation (except in Canada)

  • Sealed Transfomers

  • Non-ventilated Transformers

  • Testing Transformers

  • Grounding Transformers

  • Rectifier Transformers

  • Regulating Transformers

  • Welding Transformers

  • Machine Tool Transformers with taps of more than 20%

DONGAN SOLID STATE IGNITER

Dongan’s  SupraSpark or Solid State Ignitor line was introduced as a replacement or alternative to the traditional iron core transformers that Dongan has been manufacturing for over 50 years. The SupraSpark is an alternative to our XD series of transformers used on residential oil burners as made by Wayne, Beckett and others. We also offer a solid state version of our most popular transformer the A06-SA6 for industrial applications.  These are available in several configurations as outlined in the brochure. We still offer the iron core versions and have no intention of discontinuing them but the SupraSpark offers a lighter more robust construction with a high output.

DONGAN MAGNET IGNITION TRANSFORMERS

Dongan has been manufacturing ignition transformers since the 1950’s. We offer industrial oil and gas ignition transformers along with transformers for residential oil burners. Dongan introduced a solid state igniter in 2005 for the residential oil heat market. We refer to this product line as the SupraSpark and they can be used on all major OEM burner manufacturers. We offer these as universal mount or completely fitted for the burner. Along with this product we also offer a Service Manager’s Kit that includes two igniters and mutilple base plates and fittings.

While we have a catalog that features our most commonly sold ignition transformers, we manufacture countless more that are not shown in our catalog. Please contact us for any ignition transformer requirement that you have.

Dongan also offers have an ignition transformer tester that will test any manufacturers ignition transformer up to 10,000 volts. This product is our 1909-82 and is the preferred tester in the market place.

DONGAN THREE PHASE GENERAL PURPOSE TRANSFORMERS

Dongan has a full complement of three phase ventilated transformers from 3kVA to 300kVA We offer encapsulated three phase transformers from 3kVA through 9kVA and ventilated from 15kVA and up. Our enclosures are NEMA 3R without the addition of a costly weather shield as standard with only some exceptions at the smallest kVA which are indicated in the catalog.

Our transformers can be wall mounted or floor mounted cabinet style depending upon the kVA rating. These are UL and CUL listed and are copper wound through 9kVA although we offer copper designs on any of the products in the catalog. Our aluminum wound transformers start at 15kVA and extend through 225kVA as standard off the shelf. We also build larger custom transformers too.

In addition, we also offer TP-1 Energy Efficient Transformers starting at 15kVA and larger as required by the D.O.E. These transformers meet the minimum energy efficiency requirements as set forth by the Department of Energy in EPACT. Dongan’sTP-1 transformers begin with the prefix 43 for aluminum wound and 44 for copper wound transformers. These are competitively priced against our competition.

All of our transformers have an electrostatic shield between the primary and secondary for transient noise reduction. Insulation systems are 200° or 220° depending upon the series of transformer.

DONGAN HAZARDOUS LOCATION – HL SERIES TRANSFOMERS

HL series transfomers are designed for applications where the possiblity of a fire or explosion may result from sparks in environments containing high concentrations of dust , gases or other voltatile substances. The HL transformers wiring compartments are completely filled with electrical grade silica and resin leaving no access to tge core and coil. The feature also minimizes air spaces where combustible particulates  and gases may accumulate.

The enclosures are rated for NEMA 12 and range in size from .500kVA through 25kVA. Various voltage combinations are available.

DONGAN SINGLE PHASE GENERAL PURPOSE TRANSFORMERS

Many distribution systems these days have a high harmonic content on them attributed to all of the electronic and solid state equipment needed to operate business and facilities. Equipment such as PC’s, printers, copiers, faxes and solid state lighting control all cause a current to flow back in the neutral which traditionally did not carry and current. Neutrals now must sized at least 200% larger than in years past to accomodate this current.

K-Factor is a measurement of how high the harmonic content is in a building. Obviously the more floors and office the more equipment is needed to run the business and consequently has a higher K-Factor. Dongan’s K rated transformers are designed to handle today’s high harmonic loads. We offer transformer rated at K4, K13 and K20 but also offer higher K factor.

 

Features

  • Double sized neutral

  • Aluminum Windings

  • 220°C system

The Century series comes with secondary fuse clips on every unit that can either be installed or discarded if not needed. In addition we offer this series with factory installed primary fuse kits. All of the kits can also be “dressed up” to be totally finger safe as well with the addition of special fuse covers that we also sell.

DONGAN LIGHTING DISCONNECTS

Dongan Electric Manufacturing Company offers a broad selection of Transformer Lighting Disconnects. These products are the most advanced series of disconnects available in the market today and most important they have the approvals and certifications needed to compete and ship worldwide.

DONGAN BUCK BOOST TRANSFORMERS

Dongan offers a broad range of products for buck boost applications. These transformers are shipped as low voltage isolation transformers that can be easily reconfigured to buck or boost a wide range of voltages. The beauty of these transformers is that they are easily adaptable to most minor voltage corrections that need to be made and are an inexpensive solution to isolation transformers. They are physically smaller and lighter than the corresponding kva of an isolation unit.

A 2kva buck boost transformer can do the work of a 7.5 to 32kva isolation unit depending upon how it is configured. These will work on single or three phase applications.  We offer these an 85 series which is encapsulated and 115° C rise, 80 series which is ventilated and 115° C rise and 35 series which is also ventilated but with a 55° C rise. All of the wiring is done in the field by a license electrician. If you prefer a pre-connected auto transformer instead than please consult the catalog  for the 34 and 84 ODY series or call us at 800.428.2626. We will also help you through the connection of the buck boost transformers as well by pressing “2” for technical.

DONGAN INDUSTRIAL CONTROL TRANSFORMERS

Dongan’s 50 series industrial control transformers have been designed to the highest NEMA and industrial standards. This transformer has a long track record of proven success in the field and has been in use since the late 1960’s. This product is UL and CUL listed and is both 50 and 60 hertz rated so it can be used in many countries outside of the European Union.
