A History of Thermal Management

The Early Years

Herb Josephson served his country with the United States Air Force during World War II. Upon returning from Europe, Herb started the radiator repair shop in 1949. He repaired and serviced all types of heat exchangers. Herb was also the regional distributor for Modine Truck & Bus radiators and cores.

Off-Highway & Beyond

Herb’s son John Josephson took over in 1972. In 1988, Josephson Manufacturing Company began manufacturing and selling to off highway OEMs.

A Continued Dedication to Excellence

Josephson Manufacturing Company designs complete cooling assemblies, providing solutions for the most demanding applications. Josephson offers a complete line of engine cooling systems and components along with custom engineering service and support. Responsive service combined with total quality philosophy – you build value when you build with Josephson.

With over 40 years experience servicing OEM’s, you can count on Josephson for your cooling needs.

Round Tube Compressor & Hydraulic Oil Coolers

Round Tube Coolers provide excellent durability in harsh environmental and operating conditions. Round copper tubes, heavy gauge aluminum fins, and steel manifold designs offer up to 675psi operating pressure.

Pipe Kits, Hoses, Clamps & Fittings

Cooling system pipe kits typically include a range of components, such as silicone hoses, aluminum pipes, clamps, and fittings. The hoses are designed to be more heat-resistant and durable than the rubber hoses used in the OEM cooling system, while the aluminum pipes are designed to be more efficient at transferring heat away from the engine.

Oil Coolers

Oil coolers are used to cool hydraulics, transmissions, fuel, and gear oils. They can be made with integrated thermal bypass, pressure bypass, or a combination of both. Oil coolers can be made to stack in front of an existing cooling system, or stand-alone with hydraulic or electric fans.

Machined Parts, Threaded Fittings & Components

Custom machined engine parts and components are specifically designed and manufactured for a particular application. These parts are typically made from high-quality materials such as aluminum, titanium, or stainless steel, and are machined to precise specifications using advanced manufacturing techniques.

Low Noise Fan Systems

Low noise cooling fans are an important component in many cooling systems, particularly in applications where noise levels are a concern. By using design features and control systems that minimize noise, these fans can provide effective cooling while maintaining a quiet operation.

Hydraulic Fan Drives, Pumps, Valving & Controllers

Hydraulic fan drives are a type of fan drive system that uses hydraulic power to drive the cooling fan in a vehicle’s cooling system. The hydraulic fan drive system consists of a hydraulic pump, hydraulic motor, and control valve.

Fuel Coolers

Fuel coolers, also known as fuel heat exchangers, are devices used to cool the fuel in a vehicle’s fuel system. They are typically used in high-performance and racing applications where the fuel can reach high temperatures due to the increased demands placed on the engine.

Fans (Steel & Composite)

Steel engine fans are typically made of stamped or welded steel and are commonly used in older or traditional vehicles. They are generally durable and can withstand high temperatures and stresses. However, they are relatively heavy, which can affect engine performance, and they can also be noisy during operation.

Engine Up-Fit Kits

Engine up-fit kits typically consist Engine Mounting and Cooling System Bracketry, Cooling Package (ie Jacket Water-Radiator, CAC, Fuel or Oil Coolers, Surge Tank), Pipe and Hose Connection Kit, Fan with Mounting Hub/Spacer or Fan Clutch and associated Safety Guarding, and in some cases Hydraulic System for driving the fan with required controls.

Engine Bracketry & Isolators

Engine up-fit kits are commonly used in the performance automotive industry and for custom or specialty applications where the stock engine is not sufficient to meet the needs of the owner. By upgrading the engine with an up-fit kit, it is possible to improve performance, increase horsepower and torque, and achieve higher speeds.

Copper/Brass Radiators

As old school as it can possibly get. In recent history, several major off-highway manufacturers have dropped their copper brass product lines, in most cases with some regret. Despite what some aluminum suppliers may say about it, when it comes to performance, durability, and overall efficiency, it is the king in the off-highway realm.

Complete Cooling Packages

Complete system cooling packages can consist of Radiator, Charge Air Cooler, Oil Cooler, Fuel Cooler, Transmission Oil Cooler, AC Condensers, or other coolers that are intended to provide efficient and effective cooling.

Combination Coolers

Combination Coolers make for a compact and economic solution where multiple fluids are needed to be cooled. Aluminum Bar and Plate type combi-coolers generally work well in applications under 300hp or less.

Charge Air Coolers

Charge air coolers, also known as intercoolers, are heat exchangers used in internal combustion engines, typically in turbocharged or supercharged engines, to cool the compressed intake air before it enters the engine cylinders.

Bar & Plate Aluminum Coolers

Bar and plate oil coolers are the most common type of cooler used in automotive and industrial applications. They are typically used to cool oil in high-performance engines and machinery, and can also be used to cool hydraulic fluids.

AC Condensers

AC condensers are a critical component of air conditioning systems that are responsible for removing heat from the air inside a building and releasing it outside. They are typically located outside the building, next to the compressor unit, and consist of a series of thin metal fins that are connected to a network of small tubes.
