Revamp & Modernization

Our piston compressors and diaphragm compressors as well as mills and classifier systems have been in operation for decades. Our portfolio therefore also includes the revamp and modernization of systems, plants and machines from NEUMAN & ESSER as well as from other manufacturers. In this way, we support our customers in meeting changing requirements, e.g. changed operating conditions. In addition, revamp and modernization provide support to further increase efficiency, save energy, improve service life and availability.

Revamp & Modernization of Compressors & Compressor Systems

To detail the conversion measures, we first develop the best solution as part of an engineering study in close cooperation with the operator. To do this, we use our own design tool KO³ (compressor optimization software version 3). With the help of KO³, the compressor and system components are checked and designed for the new requirements. Following the detailed engineering study, the customer receives a binding offer for the retrofit.

Machine and ATEX Guidelines

The Machinery Directive and the ATEX Directive are considered accordingly within the applicable EC legislation. A risk analysis is carried out to determine whether the revamp is a significant change or not. Customers appreciate this expertise in revamp and modernization projects, which, in addition to planning and retrofitting, primarily consider the implementation of customer-specific requirements.

Essentially, the main reasons for revamp and modernization are as follows:

• adaptation of compressor performance (Rerating)

• adaptation to changed process parameters (Reapplication)

• installation of modern energy-efficient capacity control systems not just to reduce energy consumption but also to reduce CO₂ emissions (Controls)

• technical improvements to optimize service intervals and reliability

• optimization of existing systems by pulsation studies, torsional analyses, FEM, etc. (Verification)

Revamp & Modernization of Mills & Classifier Systems

Our tailor-made revamp and modernization concepts for mills and classifier systems are based on detailed system observations. They are available for NEUMAN & ESSER and third-party systems and focus on:

• improving performance
• increasing product quality
• improving the degree of separation
• increasing system availability
• reduction of the cleaning time
• reduction of specific energy requirements
• explosion protection
• optimization of process parameters
