Rimor Srl has been a Master Distributor of Marelli Motori SPA for over 35 years and operates throughout the national and international territory.

Marelli Motori has a long tradition that dates back to 1891 when Ercole Marelli founded the company. Thanks to the experience gained in over 100 years and its excellence in “made in Italy” production, Marelli Motori has become a leader in many energy, petrochemical, naval, and industrial production sectors.

As Master Distributor, it can guarantee prompt delivery for generators, three-phase and single-phase asynchronous electric motors for powers up to 200 KW with IE3 efficiency degree.

Rimor also boasts extensive experience in the hydroelectric sector, for which it designs and supplies both synchronous and asynchronous generators.

Marelli engines in marine execution for shipboard are also available in the warehouse, manufactured according to the directives of the primary certification bodies.

Marelli Motori has the largest motor test room in Europe for tests that guarantee product quality with the final test certificate issue and the report of all the statistics collected during the test development.

As a Marelli Motori Master distributor, Rimor can quickly guarantee assistance and spare parts thanks to the Marelli warehouses’ prompt delivery.

Rimor is a Marelli Motors distributor with many years of experience gained from the collaboration with Marelli Motori. It has developed and industrialized numerous special versions of motors for applications in prohibitive environments for standard motors.

Rimor, as a leader in the production of industrial fans for high temperatures, produces electric motors for agitators and fans for ovens. Thanks to engineering and fluid dynamics simulation, Rimor has developed long shaft motors with water cooling that allow installation for applications up to 1,000 ° C.

These motors are made with materials suitable for working temperatures (for example, AISI304, AISI309, AISI310S) and are equipped with a water chamber with continuous recirculation for cooling. Rimor carries out all the studies that define the correct amount of water to be recirculated to ensure proper motor cooling.

Rimor water-cooled motors can also be used in environments where external sealing is required for treatments in an inert atmosphere (for example, hydrogen sealing).

Rimor engineering can ensure the correct power-to-axis height ratio of the motor without incurring oversizing typical; instead of applications with high temperatures; Rimor cooling systems guarantee engines a much higher life than the same products can be found on the market.

The great strength of Rimor’s water-cooled engines is also their rapid delivery, which is definitely below market standards.

Advanced technology and production capacity make Rimor water-cooled motors a highly interesting product for all companies operating in the furnace and foundry sector, and for this reason, have guaranteed numerous partnerships with major global furnace manufacturers.

The motors with air-cooled shaft are applied to dissipate the heat coming from the environment where the part driven by the motor operates

Rimor has studied and introduced a motor cooling system to the market using a finned dissipator installed on the crankshaft (Rimor blockheat). The heatsink, usually built in aluminum and equipped with a fin that better disperses the heat, dissipates the heat coming from the environment where the applied load (usually an impeller) is inserted, blocking the flow that would otherwise be directed to the motor.

This system can guarantee the operation of directly coupled fans for very high temperatures (up to 750 ° C), where the competition still uses belt transmission today.

Therefore, this solution has considerably reduced the maintenance aspect related to the transmissions and increased the efficiency of the ventilation units.

Rimor Engineering can provide calculations for critical speeds and for the maximum load that the crankshaft can drag.

These solutions are widely used in sectors related to high temperatures, such as agitators for ovens and heat treatments.

The inverter is a voltage and frequency converter capable of generating a three-phase system controlled in voltage and frequency to make it possible to change the speed of three-phase asynchronous motors or vector motors.

Rimor offers LV inverters; for single-phase voltage in the power range from 1.5 to 4 kW and three-phase voltages in the power range up to 630 kW.

All the units are equipped with a display for reading and programming, with the possibility of activating a vast number of functions to satisfy any industrial application.

The application of inverters to the various operating machines (pumps, fans, conveyor belts, mills, etc.) allows for real energy savings, as only the actual power required is consumed. Starting via an inverter takes place by absorbing the actual current required, so the high starting currents present in the case of starting with other systems must not be taken into account.

Rimor can supply inverters with IP23 and IP54 protection degrees.

The IP54 unit is equipped with filters for the inlet and outlet of the cooling air. That allows to keep the internal inverter unit particularly clean, limiting the deposit of dirt on the heat sink, the boards, and the internal components.

Therefore, the Rimor IP54 inverter is presented as a simple, robust and reliable device, containing the classic standard Rimor IP23 inverter, which is thus protected and cooled most appropriately. This solution guarantees reduced maintenance, longer life, and greater reliability of the inverter.

Our IP54 inverter units can be supplied with a series of accessories that make them particularly interesting. It is also possible to have two configurations:

• Slave; with inverter without power commands
• Independent; with switch on board and therefore the possibility of local on and off.

Furthermore, Rimor Service can help the customer in the application and perform calibration and commissioning, while an equipped internal laboratory allows diagnosis and repairs on site.

Some applications involve the execution of very low voltage auxiliary circuits and some peculiarities such as automation, remote controls or communication protocols, Rimor produces to complete its units, electrical control and control panels with inverters and PLCs of primary brands.

Rimor has a long tradition of building panels and control systems for its machinery and plants with Rina certification for installation on ships.

The electrical panel for the inverter can be equipped with multiple accessories, such as circuits for external controls, remote keyboard kit with emergency button and LED lamp for voltage presence, potentiometer for speed regulation, feedback from encoders, specific communication protocols.

It is possible to have control panels up to 630 KW of power with inverter onboard Rimor brand, an excellent quality product combined with a technical service and repair management. All switchboards usually have an IP54 degree of protection. On request, panels with higher degrees of security can be made.

The range of Rimor electrical panels also include special executions such as:

• Watertight panels with closed circuit cooling with air conditioners on board the panel.
• Forced air cooled panels with inlet filter.
