The innovation centre:
Testing Labs

FATs (Factory Acceptance Tests) are part of our testing process. These let end customers or their technical consultants personally ascertain that the equipment complies with project specifications.

Temperature, pressure, flow, and vibration transducers are connected to a monitoring computer that provides readings of the product’s operating parameters, for a complete performance assessment. The data gathered are used to calculate different performance indicators and assess efficiency, energy savings and any other parameter for satisfying project requirements. Measurement of noise emissions is a very important aspect at HiRef, which provides an off-site qualified area compliant with the UNI EN ISO 3746 standard. Thanks to our collaboration with the University of Padua, we can draw on the expertise of academics for certification of acoustic tests. HiRef also has a lab for component thermal stress testing to validate continuous operation at extremely low temperatures (as low as -50 °C).

Low-T Lab

The Low-T Lab is a climatic room used to recreate extreme temperature conditions (as low as -50 °C), simulating the coldest winter climates. This makes it possible to test monobloc telecom air conditioners; components such as test units, fans, and electrical panels; and reduced-scale prototypes. To maintain critical temperature conditions, the room uses direct expansion units connected to a two-stage compressor with sub-critical CO2 refrigeration cycle.

Data Centre Lab

Data Centre Lab is a climatic laboratory with raised floor and false ceiling used to replicate different server room layouts. The infrastructure enables us to test direct expansion or chilled water units and allows for reversible and multi-directional airflow inside the room to adapt to different test configurations. With the Data Centre Lab we can exactly reproduce actual operating conditions to test CRAC units with Upflow, Downflow or Displacement configuration.

Hyper lab

A recent addition, the Hyper Lab was entirely designed and built by HiRef's R&D department to test air to-water and water-to-water chillers and heat pumps as well as large-sized (HiRef DataBatic) and high power (up to 1.5 MW nominal cooling capacity and 2.0 MW heating capacity) air-to-air units. For air-to air units, the lab can simulate an external environment (outside air intake) with temperatures as low as -35 °C.

Off-site noise emission testing

Off-site noise emission testing

Thanks to our collaboration with the University of Padua, we can draw on the expertise of academics for the certification of acoustic tests performed in an off-site qualified area compliant with the UNI EN ISO 3746 standard. Class 1 instruments are used, providing an accuracy of 1.5 dBA under favourable environmental conditions.
