    Equipment for Construction and HVAC

    HVAC installations in commercial buildings must meet the Ecodesign energy efficiency thresholds, with low-EEI circulation pumps and correct hydraulic balancing on each circuit for even distribution of the heating medium. We supply IE5 circulation pumps, booster sets, balancing valves, expansion vessels, chillers and BMS automation. Send the estimated thermal load, the type of installation and the number of circuits for a quote.

    Frequently asked questions

    What does the EEI index of a circulation pump mean and why does it matter?

    EEI (Energy Efficiency Index) measures the energy efficiency of a circulation pump relative to a reference pump - the lower the value, the lower the consumption for the same hydraulic duty. EU ecodesign regulations (Ecodesign) set minimum efficiency thresholds for circulation pumps sold in the EU, and modern pumps with a permanent magnet synchronous motor reach an EEI below 0.17-0.20, compared with 0.4-0.6 for older asynchronous pumps. The difference translates directly into the building's electricity bill, especially for pumps that run continuously in central heating installations.

    How do I choose a balancing valve for a heating installation with several circuits?

    The hydraulic balancing valve regulates the flow on each circuit, so that all zones of the building receive heating medium in proportion to their load, not just those closest to the pump. The choice is based on the design flow of each circuit and the valve's flow coefficient (Kvs) - an undersized valve adds unnecessary pressure loss, an oversized one gives no fine control. Modern valves with digital presetting allow balancing without complex manual calculations on site, which is especially useful in large buildings with many circuits.

    Which expansion vessel do I choose for a heating installation?

    The expansion vessel absorbs the expansion of the heating medium as it heats up, protecting the installation from overpressure. Correct sizing takes into account the total volume of water in the installation, the maximum working temperature, the static pressure (the height of the installation) and the set pressure of the safety valve - an undersized vessel causes frequent discharges through the valve, with loss of heating medium and low pressure at the next start-up. For high-temperature installations, also check the membrane's resistance at the maximum peak temperature, not just at the average operating temperature.

    What is the difference between a chiller and a heat pump for a commercial building?

    The chiller produces chilled medium only, and is the classic solution for summer air conditioning in large buildings or data centres with a large thermal load to be rejected from the building. The heat pump can produce both cold and hot medium (reversible), and is efficient for buildings with mixed heating and cooling needs throughout the year, especially if you want to reduce dependence on fossil fuels for heating. The choice depends on the peak thermal load, the annual usage profile and whether the existing installation already has a separate heat source.

    What HVAC equipment do you offer for a commercial construction project and what do we send for a quote?

    For commercial projects we supply circulation pumps, booster sets for pressurisation, balancing and thermostatic valves, expansion vessels, chillers and heat pumps, plus BMS automation for integrated control. For a quick quote we need the estimated or calculated thermal load (kW), the type of installation (two-pipe, single-pipe), the number of circuits/zones and whether the project already has a principle diagram prepared by the designer. For standard equipment, the lead time is 24–72 h when the item is available locally or at the supplier, which matters on sites with tight execution deadlines.
