NOBODY GETS EXCITED ABOUT A HOSE CLIP. BUT THE SMALLEST COMPONENT CAN MAKE A BIG DIFFERENCE.

When it comes to engineering, it's often the biggest components that get all the attention. The heater, the engine and the power output.

The smaller details are just as important in helping keep everything working as it should.

At Preheat Engineering, we know that a reliable heating installation involves more than simply choosing the right heater. It's about selecting the right components for the application.
Our range of accessories is designed to make installation, servicing and ongoing maintenance easier.
Our anti vibration kits help protect coolant heaters mounted directly to Clarke engine blocks from excessive vibration. Non return valves help prevent coolant flowing backwards through the heater, while isolation valve kits make heater replacement and servicing easier.
We also supply hose clips, mounting brackets and specialist fire pump hose sets compatible with Clarke IK6 and IK4, and John Deere JU4 and JU6 engines. Each hose set includes the fittings and hose lengths required for the relevant application.
And then there are our Peregrine Serviceable Tank Level Gauges, designed to provide clear visibility of fluid levels using a coloured ball float. Made with durable, high temperature tubing and brass fittings, they are suitable for demanding environments and can be dismantled and cleaned when required, helping extend their useful life and reduce unnecessary replacement.
Designed primarily for water and coolant tanks, the tubing can also be cut to suit the specific installation, making these gauges a versatile and practical solution.
These components might not always be the most noticeable parts of an installation, but they each have a purpose.

Because good engineering isn't just about the main component. It's about getting every detail right.

We think about keeping the engine warm. But what about the battery?

When equipment is operating in very cold conditions, the battery can become an important part of the reliability equation.
Cold temperatures can affect battery performance, so maintaining the battery at a suitable temperature can help it operate efficiently when it is needed.

That is where PEREGRINE Battery Pan Heaters are intended to help.
PEREGRINE battery pan heaters are designed to maintain the battery temperature at a level to allow the battery to operate efficiently.
They are generally used in ambient temperatures below −10°C and incorporate an internal thermal cut out set at 40°C for safety.
The heaters can be fitted in multiples where required, depending on the size of the battery tray and the number of batteries involved.
They are ideally controlled by a separate air thermostat fitted to a nearby panel.
And with a large range of voltages available, including low voltage DC, together with a range of wattages, they can be specified to suit different battery applications.

Reliable equipment operation in cold conditions depends on more than keeping the engine warm. Fuel and battery performance also need consideration.

A small component can make an important difference when equipment has to operate in demanding cold conditions.

Heat isn't the only thing an engine heater has to deal with.

Vibration can be just as important.

When a coolant heater is mounted directly onto an engine, it is exposed to the same vibration generated during engine operation.
Over time, excessive vibration can place additional stress on the heater and its components, potentially compromising its operation and reducing its usable life.
Ideally, heaters should not be mounted directly to an engine where there is an alternative installation option.
But in some applications, direct mounting is necessary, particularly where space or installation requirements leave no alternative.

That is where an Anti Vibration Kit can make a difference.
Preheat Engineering PVAC Anti Vibration Kits have been designed for applications where a heater needs to be mounted directly to a Clarke engine or where high levels of vibration are present.
The kit uses a mounting plate, U bracket and rubber anti vibration mounts to provide additional protection between the heater and the engine.
It is also retrofittable, making it a practical solution for existing installations.

Heat + Vibration + Time

Considering the environment an engine heater operates in is just as important as choosing the right heater for the job.
For Clarke engine applications where direct mounting is required, we would always recommend fitting an anti vibration kit to help protect the heater and extend its usable life.

ATEX Zone 2 explained

ATEX is an important consideration when specifying equipment for environments where potentially explosive atmospheres may occur.
A Zone 2 area is a location where an explosive atmosphere is not expected during normal operation, but could occur occasionally and, if it does, would only be present for a short period.

This can occur where flammable gases, vapours or mists may be present.
Equipment installed in these environments therefore needs to be carefully selected. Electrical equipment must be appropriately designed and certified for the particular hazardous area so that it does not present an unacceptable ignition risk.

This is particularly important when heating fuel tanks.
Where fuel needs to be maintained at the correct temperature within an ATEX classified area, a standard heater may not be suitable for the application.
Preheat Engineering offers ATEX Zone 2 certified fuel tank heaters, with IP66 protection, providing a heating solution for applications where these requirements apply.

Potential applications include:
• Oil and gas
• Petrochemical facilities
• Fuel storage and distribution
• Chemical processing
• Gas processing
• Biogas and anaerobic digestion
• Offshore and marine environments
• Industrial power generation

The important consideration is that selecting a heater is not simply about achieving the required temperature.
The operating environment, hazardous area classification and equipment certification all need to be considered.
The right heating solution starts with understanding the application.

BIOFUEL IS GREENER… BUT WHAT HAPPENS WHEN IT GETS COLD?

Renewable and biofuels are often discussed as part of the move away from fossil fuels, but engineers must also consider temperature.

As fuel gets colder, its physical properties can change. Lower temperatures may increase viscosity and, in some fuels, cause waxing or crystallisation. This can restrict fuel flow and create challenges for reliable engine starting and operation.
This is especially important for equipment that must be ready when needed, particularly when installed outdoors or exposed to low temperatures.

The Role of Fuel Tank Heating
The purpose is not simply to make the fuel hot, but to maintain it within the temperature range required for reliable operation.
A correctly specified fuel tank heater can help maintain fuel temperature and reduce cold-weather problems. The right solution depends on the fuel type, tank size and design, operating environment, required temperature, and application duty cycle.

At Preheat Engineering, we design and manufacture heating solutions for engines, fuel tanks, and other critical applications.

When temperatures drop, reliable fuel flow matters. Good engineering considers the conditions before the engine ever needs to start.

The part of a heater you don’t see could make maintenance much easier.

Imagine having to drain a large tank or sump just to service a heating element.
Not exactly a quick maintenance job.
For large generators, marine applications and other equipment where tanks or sumps contain significant quantities of coolant, accessing a conventional heating element can create unnecessary disruption.

That’s where a PEREGRINE YP-Type withdrawable element pumped coolant heater can make a difference.

The withdrawable element can be removed for servicing or replacement without the need to drain the tank or sump.

The integrated pump forces heated coolant around the engine, making the YP-Type heater suitable for large diesel engines and other high-wattage applications where heat needs to be transferred quickly.
That can mean less disruption to the equipment, easier access for maintenance and reduced fluid handling. It can also help simplify maintenance on installations where one or more heaters are required.

Good engineering isn’t only about what happens when equipment is running.
It’s also about what happens when something needs servicing.

Sometimes, the best engineering decision is the one that makes maintenance easier.

More components doesn't necessarily mean more energy wasted

When it comes to engine heating, it is not simply about producing heat.
It is about getting that heat where it needs to be.

A pumped coolant heater incorporates a pump to circulate heated coolant around the engine or system. This can be particularly important in larger or more complex applications where effective heat distribution is required.

The circulation of heated coolant can be particularly beneficial in a number of applications.
Larger engines may need heat distributed throughout a greater volume of coolant.

Higher wattage installations may require effective heat transfer.
Some systems need heat transferred quickly around the engine.

Additional heat exchange points may also need to be supplied with heated coolant.
Passenger compartment heating can be required in ambulances and specialist vehicles.
In remote oil and gas applications, reliable engine heating can also be essential in demanding environments.

A standard heater may be perfectly suitable for one application.
A pumped heater may be the better solution for another.

It is not about choosing the biggest heater or simply adding more power.
It is about choosing the right heating system for the job.

Engine size, coolant volume, installation configuration, required temperature and heat transfer requirements can all influence the most suitable solution.

At Preheat Engineering, our focus is on understanding the application and providing the heating solution that works effectively for it.

Winter failures don’t start in winter.

They often start months earlier.

By the time temperatures drop and a diesel engine struggles to start, fuel systems begin to gel or equipment starts experiencing unexpected downtime, the underlying problem may already have been developing.

That’s why now is the time to prepare.

Checking heating systems, fuel tanks, fuel lines, filters, electrical connections and other cold weather equipment before winter arrives can help identify potential problems before they become costly breakdowns.

At Preheat Engineering, we believe effective winter preparation is about more than simply adding a heater.
It’s about understanding where heat is needed, how much is required and how the system needs to operate in the real world.
Don’t wait for the first cold morning to find out your equipment isn’t ready.

Winter preparation starts now.

Not all pre-heating is the same

When someone says, “We need a heater”, the next question is
What exactly are you trying to heat?

At Preheat Engineering, we manufacture different heating solutions because the location and method of applying heat matter.

Engine coolant – heating and circulating coolant to pre-condition an engine.
Fuel tanks – applying heat where it is needed to help prevent fuel from waxing or gelling.
Oil sumps and tanks – using direct heating where warming the oil itself is the priority.
AdBlue/DEF – requiring a heating solution designed specifically for the application and the properties of the fluid.

The right solution isn't necessarily the heater that produces the most heat.
It’s the one that delivers the right amount of heat, in the right place, in the right way.

That’s why at Preheat Engineering, we don’t just manufacture heaters.
We engineer heating solutions around the application.

If you’re looking at a pre-heating requirement and aren’t sure which approach is best, our team can help you work through the options.
