C.E Niehoff & Co. was founded in 1923 and has become the world leader in the design, manufacture and supply of heavy duty brushless alternators. Our strength is understanding the customer requirements and tailoring the most appropriate electrical power solutions to meet them, whether it is by utilising existing in house technology or developing a bespoke solution.

Heavy Duty Brushless Alternators

Our Standard products range starts at 140A and goes up to 910A and can be supplied as either 14V, 28V or in dual voltage format. There is a wide variety of mounting methods and drive systems and this reflects the numerous military vehicles powered by our alternators.

CEN alternator design favours a stationary field coil which eliminates the need for brushes and slip rings that wear and need periodic replacement thus providing the highest reliability, serviceability and durability in heavy-duty arduous applications... Their elimination greatly reducing the amount of generated electromagnetic interference (EMI). 

Being air cooled also simplifies the installation, reduces cost and minimises the parts count.

C.E Niehoff’s high efficiency alternators reduce the power required from the engine to produce  electrical power, this saves fuel and makes more engine power available for other purposes. C E Niehoff alternators generate less waste heat, provide higher charging currents at low engine speeds and operate at 70% efficiency, compared to 50% or less for a typical claw pole alternator.

Dual-voltage operation, over voltage cut-out, load-dump protection, reverse polarity protection, EMI suppression and the ability to meet Military Standards makes CEN  the market leader. Many of the above features are available in our commercial alternators that operate in the equally arduous world of Emergency Service vehicles, Mining and Public Transportation. These high-tech capabilities have earned CEN a reputation as an engineering innovator; anticipating future requirements and designing for tomorrows demands.

Regulators/Electrical Power Supply

Every C E Niehoff Alternator is supplied with a regulator that can be set to match the battery charging characteristics or work several alternators together. The more advanced regulators can link main engine systems to APU’s via J1939 communications creating an integrated vehicle electrical system.

Power Management and Battery Monitoring Systems

CEN’s Electrical Power Manager (EPM) is a multi-function device that consists of high-current, bi-directional switches, with programmable electric power source to respond to vehicle operating conditions, electric load status and various fault conditions. Its features include:

• Solid-state automatic battery connect and disconnect
• Protected 28V and 14V auxiliary output power
• Automatic reverse-polarity protection for vehicle loads
• LED diagnostics
• Automatic battery-less operation when used with a compatible voltage regulator
• Battery information such as voltage and charge current
• Capable of communication with other vehicle digital systems via J1939 data bus

Systems using multiple alternators can be designed to operate with a single regulator providing over 2000A and communicate with the vehicle management system using the EPM.

Other systems include the Auxiliary Battery Controller (ABC), an intelligent, programmable battery isolator - isolates the main battery and auxiliary battery from the alternator and starter, making them independent power sources.

The Load Battery Control Device (LBCD) enables an energized operating alternator to generate power for vehicle electrical loads without requiring a battery in the circuit (battery-less operation). The device has the capability to recharge a designated number of batteries or energy storage capacitors at a different voltage to that of the vehicle electrical system voltage.

Service Repair

All our products are fully supported by our repair and rebuild facility which can provide routine maintenance, accident repairs or damage investigations. The team also provides a training facility for our Customers to ensure they maximize the reliability of their electrical power supply systems and minimise vehicle or system down time.

Auxiliary Power Units 

As well as alternators, we provide Auxiliary Power Units; through our sister company Goodman Ball Inc., GBI uses only proven components, which have an established track record, as well as having access to the entire inventory of alternator models from C.E. Niehoff & Co.

To learn more about DRASH products, please visit our website at www.drash.com

Featured Products:

J Series Side Mounted Large Screen Display Systems

This quarter’s featured product is the J Series Side Mounted Large Screen Display System. It is the newest addition to the DRASH Deployable Command and Control Equipment.

The purpose of the J Series Side Mounted Large Screen Display System is to increase mobility throughout DRASH shelters by eliminating the need to set up DC2E along the shelters' width. Instead, the new Side Display System posts on the shelters' length. Such a design enables personnel and equipment to move freely throughout the length of a DRASH shelter without restriction. The new design also allows military personnel to connect various shelters as needed to increase the size of the overall system.

Rapid Military Deployable Shelter Systems

DRASH Deployable Rapid Assembly Shelters are the epitome of quick and efficient soft walled technology. Superior protective elements and reliable features are what make these shelters so functional and unique. All shelters are rapidly deployable and structured with an advanced, highly flexible composite material called Titanite®. The shelter’s frame is comprised of pairs of Titanite® struts that connect at key points in the framework called hubs. These hubs allow for rapid deployment, as they enable the entire shelter to be pushed up and out swiftly without additional assembly.  The shelter comes pre-attached with a double layer of Xytex, a high-tech fabric that provides insulation from hot and cold temperatures.  The specially coated fabric is fire retardant, water repellant and resistant to mildew, abrasion and ultraviolet rays.

DRASH Shelters come in a variety of sizes and divide into separate categories according to their width.  Beginning with the smallest C Series shelter, at 109 square ft. (2.3 meters) and ending with the largest J Series shelter, at 1,250 square ft. (116 meters), the range in size accommodates a diversity of client needs.  In addition, every shelter is easily connectable to any other shelter regardless of the series or model.
A key component to the DRASH Shelter System is the Utility Support Trailer (UST).  A UST is an integrated support system designed to provide mobility, power and or environmental control for all DRASH shelters.  USTs come in various models, tailoring to the energy needs of every mission. Depending on the model, a UST comes equipped with a generator and/or ECU. Models that are equipped with ECUs enable the shelters to function in harsh climates. Some trailers incorporate a new energy efficient Intelligent Power Technology (IPT), while other trailers have traditional analog systems.  All trailers are operable in rough terrain, and are easily towable by military vehicles.    
Every element within a DRASH Shelter System has undergone rigorous testing to meet all Military Standard Requirements.

Intelligent Power Technology™ - IPT

Interconnectable Trailer-Mounted Generators

Intelligent Power Technology (IPT) is a reflection of DHS’s effort toward creating energy efficient products. The DRASH IPT enables users to interconnect various trailer-mounted generators to form a micro grid of networked power.

When activated, each generator responds to real time power demands. The system is self-adjusting but users have the ability to monitor activity from inside the Tactical Operations Center.  Because IPT responds to the user’s power needs, it eliminates wasted energy expenditure in unoccupied areas of the shelter. Having, IPT reduces unused energy, which ultimately minimizes unnecessary fuel costs.

Deployable Command and Control Equipment (DC2E)

DRASH Deployable Command and Control Equipment (DC2E) encompasses projector systems, audio visual switching systems and system accessories , all designed to facilitate information management on the battlefield. 

DC2E equipment is portable and lightweight so setting up and dismantling requires minimal time and few personnel.  Front/Rear Projection Systems are available with Medium, Large, and now Side Mounted Screen Displays.
