Rotenso Aquami AQS40X1o Heat Pump 4kW Split 1PH Outdoor unit


Heat pump Rotenso Aquami 1F 4KW SPLIT 1F AQS40X1o outdoor unit (outdoor unit)

The Rotenso Aquami Split heat pumps consist of an external unit (unit) and a hydraulic module (for indoor installation).
They are sold as separate components of a kit.

The Rotenso Aquami Split 4 kW heat pump consists of:

  • an outdoor unit with the symbol AQS40X1o
  • an indoor unit: a hydronic module with the symbol AQS60X13i or a hydronic module including a DHW tank of 190 litres (AQS100T190X1i) or a DHW tank of 240 litres (AQS100T240X1i).

It is a single-phase pump with a heating capacity of 4.25 kW (A7/W35) and high energy efficiency class A++ (for 35° flow temperature) and A++ (for 55° flow temperature).
It provides high heating capacity down to an outdoor temperature of -25°C and can operate without the aid of electric heaters even at an ambient temperature of -15°C. The maximum available water temperature in heating mode is: 65°C and in DHW mode it is: 60°C.

The pumps come with as much as a 5-year warranty. The buyer is assured of professional service and warranty care. The manufacturer provides free of charge start-up of the pump by an authorised service, access to a nationwide service network and fast service response time.

In order to ensure trouble-free operation at temperatures below 0°C, the pump is equipped with a drip tray heater, the operation of which protects against freezing of condensate and frosting of the external unit, thus preventing possible damage to the fan and heat pump exchanger.
The second important element of the pump's equipment is the compressor crankcase heater which, at temperatures below 0°, heats the compressor oil preparing the unit for trouble-free start-up in adverse weather conditions.
This technical solution guarantees failure-free operation and extends the life of the compressor - the heart of the heat pump.

The AQS40X1o heat pump is equipped with a 9 kW booster heater with modulating power (3 kW +3 kW + 3 kW).
In emergency situations or at temperatures below -15° C, it is sometimes advisable for the heat pump to use booster heaters to prepare central heating or DHW for economical operation. It is worth bearing in mind that the use of heaters has a beneficial effect on the durability and reliability of the heat pump.
It is worth bearing in mind that in emergency and extreme situations, these heaters may take over as the only source of heat.

The Rotenso Aquami AQS40X1o heat pump is a user-friendly appliance for day-to-day operation.
Easy service access is ensured by the placement of the automation and hydraulic components in the indoor unit and the USB function enables the pump's software to be quickly updated . Simply copy the stored parameters between the controls using a memory stick. The use of a single-fan design with a bionic vane pattern, a two-rotary compressor and optimisation of the piping design have significantly contributed to the quiet operation of the pump.

The Rotenso Aquami pump can be controlled from a mobile app as well as a modern wired controller with a menu in Polish.
