Integrated heat pump AHU module with R290 and R454C options
5th July 2026
SWEDEN: IV Produkt has launched cooling and heat pump modules, compatible with both R290 and R454C refrigerants, for integration in its Envistar series of AHUs.
The ThermoCooler HP, a reversible heat pump with stepless cooling and heating power, reduces the need for separate external chillers, boilers or heat pump installations in many applications. A cooling-only version, the EcoCooler, offering the same R290 and R454C options within an integrated AHU design, is also available.
Unlike many traditional integrated systems, which are often based on cooling-led layouts, the ThermoCooler HP has been developed around the heating demands of northern European climates, while retaining the ability to provide comfort cooling when required.
The DX system and heat exchangers are positioned on the warm side of the thermal wheel. This means the heat pump is not exposed to cold air entering the AHU, or the associated problems with frost accumulation on the heat exchangers that can affect traditional reversible systems during winter operation. This allows the system to deliver continuous heating without defrost cycles, helping to avoid capacity reduction, downtime and supply air temperature fluctuations.
The design also allows the AHU to prioritise the thermal wheel as the first stage of energy recovery and maintain temperature exchange efficiency. The control algorithm prioritises the thermal wheel and only calls on the heat pump when additional heating is required. In cooling mode, free cooling and night-time cooling can be prioritised before the DX cooling cycle is activated.
Both the R290 and R454C versions have been tested for more than 45,000 hours.
Calibration-free leak detectors are incorporated in both versions, while the R290 version is also equipped with IV Produkt’s evacuation dilution function, which is designed to dilute and evacuate refrigerant in the event of a leak.
Units are available with air flows from 0.25m³/s to 10.4m³/s, with cooling capacities of 3kW up to 170kW or 250kW, depending on the version. EERs are up to 6 in cooling mode and COPs of 6-15 in heating.
The products are designed, factory tested and CE marked with the application of relevant IEC 60335-2-40 and EN 378 requirements.
