electric flow water heater with adjustable power, electronic switching and pressure operation MKX 4.5/7kW

Product detailed description

Electric flow water heater MKX-2 by HAKL, with adjustable power, electronic switching and pressure operation, 4.5/7 kW.

HAKL MKX is structurally and parametrically developed from the model range MK. It is intended for demanding consumers who require comfort as well as energy savings. Simple manual switching of heating spiral powers is appreciated by customers in the case of using, for example, a sink and shower mixer. During showering, there is an increased demand for hot water, so the heater operates at full power. In the case of using a sink, half power is sufficient.

The two power levels are also useful for year-round operation, especially in the winter period when the incoming water is colder and the increased heating power finds its use.

CHARACTERISTICS:
• installation on non-pressure and commonly available water mixers
• pressure operation 6 bar with switching from 0.06 MPa
• electronic switching by control unit
• connection to 2x230V, adjustable heating power
• immediate and continuous water heating up to 50 °C
• possibility of power switching (winter / summer mode)
• electronic two-stage protection against overheating of spirals

SPECIFICATION:
Pressure operation: installation of the heater is possible directly into the water supply system for one or more commonly available water mixers.
Electronic switching: water heating is controlled by an electronic control unit, which uses protective sensors and thermal fuses.
Power switching: possibility of switching the power of the heating spiral.
Water tightness IP 24: possibility of installing the heater above or below the sink
Voltage 2×230 V: connection to a three-phase electrical network. The heater is installed only on two phases from the three-phase electrical distribution.
Mounting bracket: simple wall installation is enabled by the installation bracket and screws included in the package.
Metal flange: massive design of the metal flange increases the durability of the heater during installation.
Light indication: switching on and off of the heating is indicated by a red light on the front cover.
Compact dimensions: shape and small dimensions allow installation in confined conditions.
