Research and development
|
 |
Both our two divisions, INDUSTRIAL FANS an GENERAL MACHINERY, have erected modern independent laboratories, provided with state-of -the-art instruments, which enable us for the essay of machine prototypes or pilot installations. We can in this way study and pre-test all the solutions proposed to each customer.
Continuous research allows the GRUBER HERMANOS company to maintain its position in first line of product development, which, in union with a policy of high productivity, allows us to reach the desired capacity of fabrication. All this being finally to the economic advantage of our clients. |

Modern tools that are reliant on experience
All our experience of almost a hundred years has now been distilled into computer programs developed in-house by our engineers.
This means great capacity of response that allow us to answer each inquiry very quickly. We can, nevertheless, grant all the time to discuss and study a particular question when it is required.
Powerfull CAD-CAM workstations, also programmed in accordance to our quality standards, permit to accelerate the work of our Technical Office so that all drawings and designs will be timely revised and ready. |

Fabrication capability
|  |
 |
In our plant at BURCEÑA -BARACALDO we have a well skilled workforce and the most modern and specialized equipment to rationally manufacture of all kind of fans, mills, mixers and all other equipment included in our fabrication program.
As a direct consequence of our philosophy of quality controlled work we have reached an optimal efficiency-price ratio that we continuously try to improve. |

Quality control systems
In order to give our customers the highest level of satisfaction we have provided our quality control department with the most modern tools.
Basically we are able to affirm that:
- All our machines are controlled during the manufacturing process and their components tested within an strict system of tolerances.
- Metal sheets and shafts are ultrasonic and magnetoscope controlled.
- Welds are controlled by means of penetrating liquids, radiographs, magnetic particles and ultra sounds.
- Shaft alignments is made by laser techniques
- Sound levels are measured in dB(A).

The ROTORS are DYNAMICALLY BALANCED to a minimal tolerance (according to the VDI-2060 standards of the Association of German Engineers) in our original SCHENK machines which have a capacity of 20,000 Kg. for rotary parts of a diameter up to 4,500 mm.
Each machine is tested for several hours by a mechanical running trial before delivery.
Our laboratory testing unit, furnished with modern equipment, allows for the performance of the customer´s reception tests for checking the efficiency and volume-pressure characteristic curves of our fans. |
