Grupel’s Energy shines for the third consecutive year with the Five Star Award

For the 3rd consecutive year, Grupel is distinguished as the brand of reference, in the Generators category of the Five Stars 2020 Award. This distinction is based on five variables that influence Portuguese consumers in their purchasing decisions:satisfaction/experimentation; price/quality; recommendation; confidence in the brand; and innovation.Having 4 brands been evaluated, Grupel is once again the winning brand, in the Generators category, this year, which emphasizes its status as a leading company, in this sector, in Portugal.This honour is the [...]

The difference between single-phase and three-phase voltage

The difference between single-phase and three-phase voltage

The difference between single-phase voltage and three-phase voltage, respectively, simple voltage and compound voltage, is basically in the value between them. The compound voltage is √3 times higher than the simple voltage, ie V (compound) = V (simple) x √3 (approximately 1.732). This difference can be identified with a voltmeter. For compound voltage, the voltage is measured between the two phases, and for single voltage, the voltage is measure between the phase and the neutral.An alternator that supplies single-phase voltage [...]

How can you verify the necessary power for a generator?

There are several methods to calculate or verify the necessary power for a generator, learn the process and how to know which genset you need to purchase. Mainly in Portugal at major projects, the designers have at their responsibility the calculation to verify the necessary power for a generator and then define it in the contract documents of the project. In the case of private individuals, they are the ones responsible for this calculation, so the solution is to check the [...]

New features in Grupel’s soundproof cabin

New features in Grupel’s soundproof cabin

In the continuous improvement in Grupel’s soundproof cabin, we developed a design that changed the concept of manufacturing and assembling in order to upgrade the product and to make it even more competitive. We started by the model 2300 of Grupel’s soundproof cabin, and soon this design will be in the other models so that we can increase the quality of our products and meet with the customer's demand. In this new concept, we reduced the welding usage which diminished the [...]

Different Types of Fuel Tanks

Grupel has available different types of fuel tanks that can adapt to each application of the genset or customers demand. In the generators, the combustion and the fuel tank are a key element, because it’s the tank that defines the genset's autonomy. Generally, the tanks are selected and designed so that, the genset can operate in full load (100%) at least for 8 hours. Depending on the engine consumption we provide in the standard range tanks from 40L to 1000L. In the [...]

Main extras in a standard genset Grupel

Main extras in a Standard Genset

The extras in a standard genset are something very usual because one of the features that most distinguishes Grupel is the capacity to adapt its products to each case, application or purpose. With the variety of extras in a standard genset that we have available, the generators manufactured by Grupel can be customized, improved and changed according to the customer’s needs. The genset has as purpose to fulfill the energy demand, and it can be used as the main source or an [...]

Grupel Military Project

Military Project from an engineering perspective

The gensets in this military project characterize for having very complex specifications, which have many requirements and details that are destined to ease the usage of these gensets. Through the development of this military project, we intended to create a system of fast implementation where every element must allow an optimize assembly and disassembly since we have as base the Plug & Play with the purpose to facilitate the user on set. The engineering equipment resulted in two types of power [...]

military project Grupel

The process of a military project

Recently we had a big project in Grupel, a military project that had a great level of concentration and demand from every department. The process in this military project started through a tender to develop and manufacture the energy solution. After this process, the starting point was the negotiation, like usual, when it comes to develop and manufacture a project the process of negotiation is intense because it is necessary to discuss costs and more importantly the technical solutions. Since Grupel already [...]

Grupel generator installation

Precautions in the Generator Installation

Most of the gensets in Portugal, function in the emergency system, and for that, it is necessary to guarantee the good functioning of the generator installation and its precautions. For that we must guarantee: A good fresh air intake:For the genset to cool and for the combustion of the diesel engine, the installation location should contain an opening for the fresh air intake (cold) directly from the exterior A good hot air outtake:It is also very important that the [...]
