Everything from a single source: Manufacture
Manufacturing at HOF comprises the areas of metal processing, refrigeration technology & service, electrical assembly & insulation in which the electrical and mechanical assembly work and individual production jobs are taken care of by the company's own workers. The construction of the switch cabinet is just as much a part of this as the cabling of the system, the insulation and full function testing with the respective documentation.
Manufacturing steps at a glance
In manufacturing halls arranged especially for this purpose, the first phase sees the company's workers manufacture these high-quality modules in separate areas. All of this runs concurrently, so that construction time can be kept to a minimum. Since each specialist group has enough well-trained workers, the individual modules are pre-tested upon completion and the results documented.
Pre-assembly is done in the individual technical groups so that larger units can be made available for final assembly. In this way, the metalworking department, for example, can manufacture the finished chamber with condenser, all of the internal structures, the outer framing and the primed sheet-metal panelling.
The entire technical unit with refrigeration system, heat transfer system, vacuum pump sets, hydraulic system, CIP pump and water ring pump, including full framing, is taken care of by the refrigeration technology department.
The electro-technical department supplies the finished switch and control cabinets and other small pre-assembled modules.
All of these large units are then transported to available separate assembly halls for final assembly. Here, the customer's plant layout is perfectly simulated in such a way that all of the connections between the components can be established and tested precisely. In this way, it's possible to provide highly accurate results in the FAT, saving valuable time for the customer during on-site assembly.
