NOVA WERKE AG - NOVA SWISS - Pioneering spirit makes Nova Swiss your ideal development partner.

The compression space is separated from the crank mechanism by double diaphragms, thereby preventing the gas from becoming contaminated by oil. The parts in contact with the medium are made from corrosion-resistant steel. The compressor is characterized by extreme reliability, ease of use and low maintenance requirements. The compressor features overpressure protection on the oil side. Special versions for hydrogen (H2) and oxygen (O2) are also available. The compressor is equipped with a diaphragm breakage detector.

Advanced Nova Swiss technology allows high-precision gas mixing under controlled pressure. The servo motor ensures state-of-the-art pressure regulation that is optimal for the respective application. This results in maximum precision for the injection process and ensures exact gas metering at the required pressure. Benefits : High flow rates Maximum pressure precision Low maintenance costs No daily re-adjustment required Faster start-up after interruptions. Thereby less waste during the start-up process. No compressed air supply required. Contamination-free gases thanks to diaphragm technology. The Nova Swiss gas injection unit does not require compressed air, as it is the case with pneumatic amplifiers. The integrated lubrication unit allows the system to be operated at very low speed, which in turn enables the dimensioning of extremely small quantities.

The Nova Swiss hand pump with spindle drive is particularly well-suited to use as a pressure generator for smaller high-pressure systems. It is ideal for all applications in which common high-pressure media are used, including those with low viscosity. This pump can be used anywhere and is not dependent on a compressed air or power supply. The finely threaded spindle allows precise adjustment to the desired pressure. Operation is facilitated by three long crank arms. The stem does not rotate, thus significantly extending the longevity of the packing

The standardized pressure supply unit (dosing system) from Nova Werke AG allows pressures to be set with extreme precision. Nova Swiss pressure supply units are modular and available in three stages: 3,000 bar for gases and 7,000 to 14,000 bar for liquids — custom adaptations are also possible on request. Adjustable pressure Output up to 3,000, 7,000 and 14,000 bar Ultra-pure gas compression: N2, He and Ar for industrial applications and test stands Liquid compression, e.g. for bursting pressure tests and autofrettage

The heat exchangers in our high-pressure series are especially designed for extremely high-pressure ratings of up to 20,000 PSI/1,380 bar and are manufactured in accordance with customer-specific requirements and wishes. The production of high-pressure heat exchangers is ASME or PED compliant. Compliance with special approvals and directives can be arranged on request. The heat exchangers of the Nova Swiss high-pressure series thus offer our demanding customers the option to cool or heat fluids and gases (including hydrogen) without having to reduce the operating pressures.

The Nova Swiss coaxial valve is a solenoid valve that is ideally suited for applications in complex systems and harsh environments. It consists entirely of stainless material and is suitable for use under the most challenging conditions (including salt spray). Its special design guarantees extreme leak-tightness. Its small footprint and low weight make it ideal for a wide range of applications.

The ultra-compact and extremely light Nova Swiss solenoid valve is designed for hydrogen and inert gases applications for an operating pressure of up to 1000 bar. Your applications can now be realised even more cost-efficiently thanks to its minimal dimensions. The piloted 2-way on/off valve, manufactured from stainless steel, is monostable (normally open or normally closed). It features a flow coefficient KV = 0.6 m³/h. If the current drops at the solenoid coil, the normally closed valve closes reliably and tightly (safety function).

The direct operated solenoid valve offers all the advantages of the pilot operated solenoid valve at operating pressures up to 1000 bar, but is even smaller and more compact. Here too, the focus is on cost efficiency and reliability. The direct operated 2-way on/off valve is made of stainless steel and has a monostable design (normally open or normally closed). Its flow factor (KV) is 0.006 m³/h. The direct operated normally closed solenoid valve also has a safety function. In case of a voltage drop, it closes automatically, reliably and tightly.

We create the basis for sophisticated, new and optimized products in the areas of "High-Pressure Technology" and "Engine Components" by continually expanding our expertise. In addition to complex calculations, our ongoing tasks include the assessment of suitable materials and manufacturing processes. In our state-of-the-art materials lab, we carry out results-oriented material analysis for our "High-Pressure Technology" and "Engine Components" product lines. For our "Surface Technology" product line, we check the quality of coatings via elaborate analysis and test procedures. We constantly ensure that all Nova Swiss products meet the latest requirements of the market as well as all statutory regulations. Our duties: Support for the"High-Pressure Technology" and "Engine Components" areas Analysis and testing of materials and coatings New product development Optimizations

Thermal spraying processes (as classified in the EN 657 and ISO 14917 standards) offer a wide range of applications within modern surface technologies. Components made from a wide range of base materials can be coated with layers of high-melting-point metals or ceramics to protect them against wear and corrosion. Furthermore, thermally conductive or heat-insulating layers can be applied to highly thermally stressed components. Almost all coating materials that can be produced in powder or wire form can be processed in this way. During thermal spraying, the coating materials are fed into — and melted by — an energetic heat source (fuel gas oxygen flames from combustible gas, arcs or plasmas of noble gases such as argon, hydrogen, nitrogen, helium). The particles, which are either softened or fully molten, are accelerated in the direction of the workpiece and collide with it at high speed (40–600 m/s).
