The characteristics of Grupel’s Canopies

Grupel's product development team works daily for the constant improvement of each of our products, with the purpose of evolving and innovating the final product and, ultimately, satisfying the needs of our clients. From one of these improvement projects, a new type of canopy emerged which is more resistant and whose manufacturing process is faster and more flexible.But which features distinguish Grupel’s canopies?Bolted / non-welded canopyThe main advantage of the bolted canopy is that it presents very low levels [...]

Grupel solutions for the Telecommunications sector

Today's world lives on communication with others, whether in business and other professional activities, or in the personal relationships we establish. Nowadays, people all over the world maintain long-distance relationships and connections using their phones, cell phones, computers, the internet and mobile networks. The telecommunications sector therefore involves more and more automated operations, and the infrastructure that makes it up is often in remote locations where access to a structured and stable power grid is very difficult. A deficient power grid [...]

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 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 for calculating or checking the required power for a generator. In Portugal, in major works, the designers generally have the responsibility of carrying out the calculation of the required power for a generator and establishing it in the works specifications. When this responsibility rests with private individuals, the solution is to consult their electricity bill to check the contracted power. It is necessary, however, to consider that the value in the electricity bill may not be 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

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 [...]

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 [...]

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 [...]

Precautions for the Generator Installation

When thinking about purchasing and installing a generator, there are some precautions that must be taken in order to optimize its operation and eventual maintenance. Here they are: Fresh air intake:For the cooling of the generator set and for a good combustion of the diesel engine, the location of the installation must contain an opening to the outside, for the entry of fresh (cold) air. Hot air outlet:Likewise, it is extremely important that the hot air from the radiator is [...]
