Medium Voltage Frequency Inverters, Measurement Services, and Energy Efficiency Audits
Medium voltage drive implementations
The MVD (Medium Voltage Drives) division has been involved in turnkey implementations of medium-voltage inverters and soft-start systems in many projects in Polish industry for more than 15 years. Over the past few years, we have implemented more than a dozen applications based on medium voltage inverters and medium voltage softstarts, including being the first in Poland to perform a speed control application for conveyor belts by implementing medium voltage inverters in current topology. In addition, we made applications using 6kV drive systems in voltage and current topology on exhaust fans, air fans, feedwater pumps and mains water pumps. The company’s warranty and post-warranty service, excellent technical facilities and financial security have enabled it to achieve Rockwell Automation RcSI (Recognized System Integrator) certification. For Introl Automatyka, customer support does not end with the end of the warranty on the equipment and installations delivered. We comprehensively serve our customers also in the post-warranty period, providing fast response and repair times, technical support and training packages also in Polish. Numerous domestic and foreign customers therefore benefit from our top-level commissioning of medium-voltage drive systems, often in applications with the status of critical installations.
In particular, we implement:
- turnkey projects with integration of medium voltage drive systems,
- service contracts medium voltage drive systems. Our team of certified drive system engineers, guarantees fast response times,
- application commissioning – activities which historically, due to their complexity, were only performed by the manufacturer, have also been our domain for many years,
- diagnostics and troubleshooting – technical support for the customer in ongoing operation and system development work contributes to the optimisation of equipment operation necessary for the correct operation of technological systems,
- preventive maintenance – operational trainings and continuous customer support by Introl Automatyka increase the awareness of users as to the essence of preventive actions, in order to minimise unplanned equipment downtime.
Non-invasive measurement services non-invasive flow and energy measurements
For many years we have been offering the service of measuring flow in a pipeline without interfering with its walls. Only isolation of the pipeline is required. The probes flow meter using the ultrasonic method calculate the flow with accuracy of up to 1%. This method saves time and money, especially with large diameters (up to DN 4000). With the flow meter non-invasive we can also carry out the service of measuring heat or cooling energy. This measurement is made possible through the use of dedicated surface measurement sensors. The service report is used for energy optimisation calculations when auditing energy efficiency.
Check of other measuring devices at the customer’s site (flow, pressure, differential pressure, temperature).
We carry out a check of measuring devices at the customer’s site. Using high-quality standards we check the correctness of pressure transducers, differential pressure transducers and temperature transducers. We also check the correctness of the analogue output signals. Measuring devices can be dismantled immediately before checking and reassembled immediately after checking. This reduces staging time to the necessary minimum.
The non-invasive measurement allows:.
- verification of installed measuring equipment,
- checking the correctness of the technology,
- checking pump performance
- testing the tightness of gates and valves,
- determination of utility consumption,
- measurement of thermal energy
- measurement of various media (water with various mixtures, e.g. glycol, oils, acids, aggressive media.
As a result of checking the equipment, you can obtain: – a
- certificate of verification, calibration at several points,
- confirmation of correctness of signals
- confirmation of range stability,
- diagnosis of potential faults,
- process optimisation.
Energy Optimisation: Audits and White Certificates for company efficiency enterprise energy audit
In 2016, the Energy Efficiency Act was introduced, which made it mandatory for large enterprises to carry out an energy audit. The audit must be repeated every 4 years. As part of our obligations under the Act, we carry out an enterprise energy audit with the aim of identifying the largest areas of energy consumption in processes, buildings, transport, which together account for at least 90% of total energy use.
ENERGY EFFICIENCY AUDIT
In order to determine the energy efficiency of a company, we perform an energy audit showing the possibilities for improving energy efficiency in a specific area of activity. An important element of such an audit is to indicate how and to what extent the company can achieve energy savings within its operations. A energy efficiency audit is necessary for a business when applying for white certificates or applying for funding for energy efficiency improvements of the business from various programmes.
White certificates
White certificates are a confirmation of the energy savings that will be achieved as a result of a planned project improving energy efficiency. It is also a mechanism that allows for a significant reimbursement of part of the investment expenditure by selling the acquired certificates on the TGE. Certificates are issued upon application of the enterprise where energy projects are planned. The application is accompanied by an energy efficiency audit confirming the planned energy effects.
Audit businesses qualifying in the following bands:.
- employing more than 250 people,
- whose annual turnover was over €50 million,
- whose balance sheet total exceeded €43 million.
Company audit result:.
- a report produced by a qualified expert, providing an energy consumption profile,
- indications on how to reduce energy sources or maximise existing sources.
White certificate:.
The unit of value of a white certificate, as defined by the International Energy Agency(IEA)and the Organisation for Economic Co-operation and Development, is the toe – tonne of oil equivalent:
- 1 toe = 41.868 GJ,
- 1 toe = 11 630 kWh = 11.63 MWh.
Certificates can be traded on the Polish Power Exchange.
