KOSTRZEWA LABORATORY – EUROPEAN STANDARDS
Out of concern for the highest quality of our products, KOSTRZEWA has established an advanced research laboratory. Our facilities allow to test our devices for relevant parameters (efficiency, emission, energy consumption etc.) before they are delivered to our Clients.
– Many boiler manufacturers does not have access to a research laboratory, does not test their products in accredited laboratories and the data on the data plate often depart from the truth – says Paweł Kostrzewa, KOSTRZEWA Marketing Manager – The nominal power of many heating devices currently available on the market is highly exaggerated. KOSTRZEWA has established an advanced research laboratory for accurate testing of the boiler parameters including heating power – the most important factor affecting Client decision.
KOSTRZEWA laboratory was designed for testing central heating boilers up to 700 kW for conformity with PN 303-5:2012.
– We want to test our products not only to PN 303-5:2012 but to a much wider scope – adds Paweł Kostrzewa. – Our boilers undergo detailed inspections to eliminate all, even the slightest design and technical faults at the design stage. We test the operation of electronic programs and perform various mechanical and thermal tests, although those are not required to ensure conformity with the Polish Standards.
The laboratory features three test stands for devices with heating power up to 50 kW, up to 100 kW and up to 700 kW. Each test stand can operate independently and in continuous mode. The tests can be carried out all year long. The laboratory also features a cold store to collect any excessive thermal energy. The heat generated during the tests is used to heat the domestic hot water and central heating of administration buildings and production floors.
Before the products are marketed, each prototype undergoes detailed and extensive tests to verify boiler efficiency allowing for its maximum, average and instantaneous performance, and the energy consumption – maximum, average and instantaneous values – required to generate the specific power. The thermal imaging camera is used to identify any components outside the boiler that lose excessive heat to improve insulation. The laboratory also test the emission of the following components: CO, CO2, O2, NOx, PM2.5 and PM10. The priority to guarantee reliable testing of heating devices is to determine the calorific value, moisture content and ash content in the fuel with a calorimeter and other auxiliary instruments.
The advanced laboratory simulates the conditions in the house and tests the boiler program response – e.g. time to adjust to temperature fluctuations, flue gas emission, energy consumption and efficiency at variable load to determine the optimum operating conditions of the device – full-time operation at moderate power or intermediate operation with high load variations.
The Client should consider the average heating device efficiency.
