Phillips & Temro Preheaters

Stockcode:

GENHEAT supplies preheating systems from all the leading brands.

Circulation tank heaters provide pre-heating for dependable engine starts in all temperatures by circulating warmed coolant through the engine. The tank heater reduces the time needed to reach operating speed, and enhances immediate full-load acceptance. The temperature is controlled by a regulating thermostat. Circulation tank heaters are especially suitable for power generation applications

About us

GenHeat was established to address the increasing demand for specialised expertise and products in engine heating.

We provide heating solutions for diesel, fuel, coolant, engine oils, hydraulic oils, other industrial liquids, batteries, cabins, and more. Our systems enhance engine starting, reduce wear, lower fuel consumption, extend battery life, and minimise environmental impact.

An engine preheater warms the engine and maintains a stable starting temperature while it’s not in use. An engine heater can heat the engine's coolant and circulate it through the engine. This transfer of heat can occur in two ways: through a built-in circulation pump that moves the heated coolant, or via a thermosiphon or immersion heater that relies on natural convection to circulate the coolant.

Types of Preheaters Include:

Coolant Heaters
Coolant heaters warm the engine by heating the coolant and transferring that heat to the engine. Some use an electric circulation pump, known as forced flow or circulation heaters, to evenly distribute heat by pumping the coolant through the engine. Other coolant preheaters utilise the thermosiphon process, which relies on thermal convection to circulate the heated coolant through the engine.

Fuel & Oil Heaters
At low temperatures, paraffin wax in diesel fuel can begin to gel, leading to solidification and obstructed flow. This prevents the fuel from reaching the engine, causing significant issues. Oils can also experience increased viscosity in cold weather, reducing their flow to engines and hydraulic systems. These problems can be avoided with fuel and oil heaters, and at GENHEAT, we provide a range of heaters from various brands.

Circulation & Tank Heaters
In addition to enhancing sustainability, preheating offers significant environmental benefits. A substantial amount of fuel is used during engine start-up and reaching operating temperature, and a cold engine produces more harmful emissions than a warm one. Preheating reduces fuel consumption and lowers emissions, making it environmentally advantageous.

In addition to coolant heaters, we offer forced circulation heaters, thermosiphon heaters, and direct immersion heaters for warming (bio) fuels and (engine) oils.
