Rotenso Aquami AQM40X1 Heat Pump 4kW Monoblock 1PH Outdoor unit


Rotenso Aquami Monoblock heat pump AQM40X1 R14 (outdoor unit)

The AQM40X1 model is a monoblock, single-phase heat pump with a heating capacity of 4.2 kW (A7/W35).It is a highly efficient unit with 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.

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 piece of equipment is the compressor crankcase heater which, at temperatures below 0°, heats the compressor oil and prepares 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 AQM40X1 heat pump is equipped with a 3kW booster heater. 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 knowing that the use of heaters has a beneficial effect on the durability and reliability of the heat pump.

The Rotenso Aquami AQM40X1 heat pump is easy to install, maintain and operate on a day-to-day basis. The design of the pump's housing provides easy access to all its components and the USB function allows for quick software updates.

Simply copy the stored parameters between controls using a memory stick. The use of a single-fan design with a bionic vane pattern, a two-rotation compressor and optimised piping design have significantly contributed to the pump's quiet operation.

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