Flow rate is higher than that because an amount of fuel (varies per manufacturer) exits thru the injector as unused (injector return lines). Granted by the size of the injector return lines that I have seen thats not that much additional flow.

Sorry that Im not a diesel wiz but does fuel continually flow thru the injector return lines?

Just wanted to know if anyone has actually hooked up one or more of these 12V ptc thermistors to effectively heat thier filter,fuel lines,tank or other parts?
If so what did you do and how does it work? Big Grin

RE: the second link...

...like some of the other electric inline heater "alternatives", there are a few things that should be noted...

It looks like a Vegtherm, but isn't.

They don't even want to sell for automotive application, whereas the Vegtherm was designed and used for the specific task of heating vegetable oil in our application.

The push on connectors have not been used on a Vegtherm since about 2004 (we use bolted on connections and wires ready to connect).

Vegtherm - proven, effective, reliable... $99 with relay, circuit breaker, and connectors.

Self-Regulating Heaters

Features

* No thermostat needed
* Virtually unlimited life
* No moving parts to wear
* Very low cost
* No electrical noise
* Efficient

Description

Positive Temperature Coefficient thermistors are truly remarkable for their ability to function as self-regulating heating elements. They can operate at a nearly constant temperature over a broad range of voltage and dissipation conditions. PTC heaters can be manufactured in many different configurations. These include discs, rectangles, squares, cylinders, and various shapes with holes to increase surface area. Multiple PTCs can be used in parallel to provide constant heating over a larger area.

PTC Thermistor Heater - Mar, 30 2010


PTC Thermistors (thermal resistor), also called PTC stone, are ideal heating elements. Thanks to self-regulation properties, heating devices based on PTC thermistor technology can generally dispense with control and regulating components as well as with over-temperature protection, PTC thermistor heating elements are used wherever measurement and regulating equipment as well as heating devices must be housed in tight confines. PTC Heating elements can be designed to be square, rectangular, round, ring or doughnut form, or housed in aluminum, stainless steel, silicon casing.

The POP Diesel Electic In-Line Heater™ (patent pending) is built to provide better heat transfer for vegetable oil fuel than any other electric heater on the market. It allows the free flow of fuel while incorporating an internal structure to increase surface area for heat exchange and more precise fuel temperature control.

A very nice description of the technology used in the Vegtherm and Vegsensor, which were both professionally designed to our specifications for the task at hand. Since we buy in bulk, we have been able to offer at competitive prices in a complete and available package tailored to the SVO application. Thank you for posting, Omar, and have a Merry Christmas.

Heated in-line fuel standpipes (ТП) are intended for the diesel fuel intake from the tank under extended ambient temperature range including under low temperature conditions down to -40°C when the intake of the frozen and condensed fuel is impossible by standard fuel standpipes. The pre-starting period fuel and slotted filter heating is conducted by electric heater operating on car battery (car system) power. During engine operation fuel heating is conducted by heated return fuel in the ТП-101 (102) as well as by heated fluid – engine cooling system antifreeze in the ТП-201 (202) and ТП-301 (302). Liquid heating maintains battery power capacity and depending on temperature and applied ТП model usually provides fuel patency along the entire fuel main line. Under low temperature conditions the simultaneous electric and liquid heating is provided.

Heated fuel standpipes ТП-100, ТП-200, ТП-300 by NOMAKON™ in their modifications have the same length and the same mounting dimensions over flanges and nipples as standard fuel in-line standpipes in the MAZ, KAMAZ trucks and others. Consequently, ТП may be installed instead of a standard fuel standpipe as well as a special spare fuel standpipe for winter conditions.

ТПs have manual heating control and are also connected to the system of automatic heating control system СПА-101 (201). In the case of manual control a switch with indication is mounted in the cabin within visibility zone from the driver's seat. The switching-on of the heater is conducted by pressing the button of the switch.

Thanks to the innovative injection molding technology for PTC ceramic, FormFit™ heating elements from EPCOS can be fashioned into virtually any shape or form imaginable such as tubes, nozzles or rotor blades of ventilators.

Hello Guys, long time since I've been here reading.
Discovered you were discussing heaters, so I just thought I could show you this one enclosed here.
The filter itself is built in inside the heater, which is a double walled cup, where coolant water circulates inside. Thought it would be better than the copper tubes around the filters as i have seen here. We have two sizes of them for standard filter-head.

The small one has a cap. of 35l per 100 km, the other one 35 l per 100 km,
Price is 48 $ each. The filters should last 20 000 km if you use good oil.
Filter is 5 micron rated.
Also suitable for Common Rail and PDI, pressure tested up to 6 bar 230 psi

Are they just coolant heated or is there an electric heater also?
do you manufacture the filters? looks good
