NOBEL V: the new frontier of vertically-arranged compression by Power System

Distributed across three sizes, the range covers a power range from 18.5 to 90 kW, introducing important innovations in terms of mechanical configuration and energy control. What makes it unique in its kind is above all the “TWIN” range from 55 to 90 kW, which houses two independent and synchronized machine systems: an innovative design choice that allows for a level of flexibility and control never reached before in this category.

Below are the key elements that define the value of the NOBEL V range and place it at the top of the market:

1. Maximum capacity and specific power at the top of the category
   The first distinctive element of the NOBEL V range is the extremely high volumetric dispensing capacity. Each size has been optimised to ensure a maximum flow rate higher than the reference standards, making the most of the efficiency of the vertically-arranged air-end.
   This feature translates into greater compressed air availability for the same installed power, offering end customers a tangible operational advantage: more compressed air, lower specific consumption, greater reliability over time.

2. Control range width: flexibility up to 6%
   Notably, on the TWIN range – with powers of 55, 75 and 90 kW – the design has introduced an unprecedented innovation: two independent machine sets, but integrated into a single system, working synchronously and dynamically. This approach allows the quantity of air supplied to be modulated with extreme precision based on the actual needs of the system, pushing the control range in some models up to 6% of the total capacity.
   The result is a smart and adaptive energy management, able to drastically reduce waste, optimize partial loads and ensure operational continuity even in highly variable conditions.
   This flexibility represents a significant competitive advantage for distributors, who can offer end customers a truly tailor-made solution, capable of adapting to a wide range of industrial applications.

3. HDPM Motors: Tailor-Made Power for Vertical Compressors
   The technological heart of the NOBEL V range is represented by the HDPM (High Density Permanent Magnet) motors, developed exclusively for application on vertically-arranged screw compressors. These engines offer superior efficiency, great responsiveness even at low revs and an ideal power density to reduce the overall size of the machine.
   The integration between the motor and the air-end has been designed to ensure maximum mechanical synergy, minimising losses and optimising transmission. Furthermore, the choice of permanent magnet motors allows for greater efficiency in all operating conditions, helping to reduce energy consumption and extend the useful life of the system.
   The high efficiency of HDPM motors also allows for air cooling, eliminating the need for complex cooling systems and ensuring a long operating life for the bearings, thanks to minimal motor heating.

4. Compact units, small footprint
   The whole NOBEL V range has been developed with a precise focus on space optimisation. The three carpentry sizes feature a vertical design that allows for minimal floor space need, even considering the spaces required for maintenance activities.
   The concept of compactness translates not only into space savings in the compressor room, but also into a rational arrangement of inner components and greater accessibility, resulting in reduced intervention times and more efficient service, with a consequent reduction in management costs.
   For distributors, this means being able to offer a competitive product even in contexts where space is a critical variable.
5. Smart regulation
   NOBEL V TWIN models, equipped with a double compression system, are pre-set in ISC (Internal Sequencing of Compressors) mode. This system allows you to automatically activate or deactivate the compressors based on the actual demand for compressed air.
   The objective is twofold: on the one hand, to maximize energy efficiency in all load conditions, on the other, to optimize work cycles by distributing them evenly on the two units and extending the maintenance intervals.
   ISC regulation stands for a strategic function that identify the NOBEL V TWIN range, making it particularly suitable for systems with variable loads and continuous changes in air demand.

6. Simplified maintenance with unified kits
   A further strength of the NOBEL V range is the extreme rationalisation of the components used between the different sizes. This allows you to manage the ordinary maintenance of the entire range with just two spare parts kits, valid for all machine families.This design choice offers significant advantages for distributors and service centres, enabling them to optimize their spare parts inventory, simplify after-sales logistics, and speed up maintenance, with a positive impact on costs, time, and service quality.
