The aim of Venair is to offer not only hoses, but complete systems of fluid transfer specially designed to get the most optimal solution for the specific application required by the costumer. Our Engineering and R&D departments work continuously in the development of new constructions that allow the improvement of the features and functionalities of the product, so that our client increases the performance of his processes and reduces machine downtime and maintenance costs. In this article, we will provide about a few examples of custom made solutions that we regularly provide to our customers:
Heated hose construction
An example of this is the heated hose with spiral reinforcement in stainless steel and electrical resistance, which maintains optimum fluidity of the conveyed product. Recent advantages in this field affect the control of electrical power and the end-to-end temperature of the hose through an electronic controller, the optimization of consumption or the installation of new connectors, which facilitate assembly.
Optimization in the efficency
Based on empirical tests conducted in the laboratory, a study of energy efficiency was carried out. This study has optimized the design of the heated hoses according to temperature of work, the diameter and the time it takes to reach this temperature.
Completely designed on demand
The result of this study has been represented graphically by combining the heating time and the temperature of work. In this representation, there is an intertwining of different trend curves. Each trend curve represents the diameter of the hose. With this graphical tool, the hose construction is optimized, as the combination of the temperature of work and the diameter given by the customer will determine the optimal design of the hose in order to reach this temperature, if the time it takes to reach the energy consumption is known.
Completely made under demand
Due to its technical characteristics, this type of hose maintains optimum fluidity of the conveyed product, which prevents solidification. Therefore, it is very suitable for the transmission of viscous products as glycerin. The hose can be manufactured completely in accordance with the demands. Furthermore, it can also be strengthened internally with different elastomers to optimize its performance according to its use. The voltage component can also vary in accordance with the demands. In addition, its temperature range can vary between 5ºC and 200ºC, but it can also withstand extreme temperatures for brief periods of time ranging from -60ºC to 200ºC.
Maintenance of temperature from one end of the hose to another without cold areas, offers a wide range of possibilities for the products that require constant temperature to prevent degradation. Moreover, the probe placed inside always allows a temperature control .
Venair SZR® connections
This type of hose can be equipped with clamp connections: DIN, SMS, or BSP, and has certifications according to the FDA, USP class VI and BfR, among others. Connections incorporate Venair’s SZR® system, which eliminates areas of retention between the metal connection and the hose in order to avoid any possible contamination.
Developement of highly transparent silicones
Another example of this is the development of highly transparent silicone for processes where the display of the conveyed product is required. This type of transfer hose is specially designed for the transport of liquids or semi-liquids in pharmaceutical, biochemical, cosmetic or food industries, because of its high thermal wear resistance, which has a constant range between -60°C to 180°C, and all the way up to 200°C for short periods of time.
Tested and certified
This silicone allows sterilization of the hose by hot air up to 250°C or steam up to 135°C, as well as cleaning products, such as caustic soda and dilute nitric acid. It is constructed with certified material, according to the FDA, USP class VI standards and BfR standard part XV, and it complies with the European directive EU 2002/95/EEC regarding the Restriction of Hazardous Substances (RoHS).
The possibilities of modification are enormous regarding of the hoses’ mechanical properties and the properties of the formulation of new silicones. This great effort in the R&D department goes in two directions: the, until now, unprecedented benefits in the market, as well as the adaption to specific demands in highly technical industries such as the pharmaceutical and biopharmaceutical industries.
