Grid heaters

Grid heaters are type of devices designed to pre-heat the air sucked into the cylinders to the temperature necessary to ignite the air-fuel mixture when starting the engine and thereby facilitate starting diesel engines. The use of heaters, as well as other types of starting aids, is designed to provide quick and reliable engine starting, reduce emissions, reduce fuel consumption at start-up and reduce engine wear.

A distinctive feature of grid heaters is their design and installation location.

Grid heaters consist of a metal housing with mounting holes around the perimeter for installation on the inlet manifold. At the request of the consumer, the heaters can be built directly into the engine inlet manifold and may not have their own housing. The housing has a through hole through which the air flow passes, with a heating coil installed. The ends of the spiral through a threaded connection are brought to the outer sides of the housing for connection to the on-board electrical network. The connection to the on-board network is carried out through terminals located, as a rule, on the heater body. Grid heaters are usually installed in the inled manifolds of engines.

Suitable for various types of engines, from 1.5L or even less to 24L or more for large vehicles.

Rated voltage: 11 V (for 12 V), 22 V (for 24 V) (other voltages are also possible upon request).

Electrical power: 390W — 3600W.

The consumers of ISKRA grid heaters are large machine-building companies such as John Deere, Deutz, CNH Industrial, Lombardini / Kohler, MAN, Cummins. ISKRA grid heaters are also commercially used on YaMZ engines, as well as on GAZ vehicles with Cummins engines.
