MTM MX 20 electric heater (10/20 kW)

MTM XE portable electric heaters are designed to operate in difficult conditions without failure. They are intended for reheating and heating various rooms with worse thermal insulation. They are most often used to heat production halls, workshops, warehouses, workshops, social rooms, shops, warehouses, garages, guard booths and even flats. They are perfect for construction and finishing works, supporting the work of e.g. dehumidifying rooms and accelerating the performance of plastering, painting or restoration works.

The undoubted advantage of electric heaters is their high mobility - you only need to provide access to the electrical installation, in the outdoors you can use power from power generators, and thanks to the low weight, you can easily change the heater's place of operation. These are devices for professionals, designed to operate without failure in difficult conditions. Professional quality; 99 hour ON / OFF timer; compact, metal housing; high efficiency; quiet work; no exhaust emissions and no oxygen consumption are the features of electric heaters, thanks to which they can be used in rooms where people and animals are present. The fact that no water vapor is released prevents the accumulation of moisture in the rooms and supports their drying.

MTM XE heaters are equipped with an adjustable timer up to 99 hours and an adjustable thermostat - if the temperature in the room is lower than the temperature set on the thermostat, the device will start heating. After reaching the temperature set on the thermostat in the room, the device switches off: the heating elements and the fan stop working. After the temperature in the room decreases, the device automatically starts heating by turning on the heating elements and the fan.

The heating power is regulated by the main switch, which can be set to 1/2 or 1/1, depending on the model. Models from 9 kW to 20 kW can work in the fan mode after selecting the mode with the main switch marked with the fan pictogram.

In order to better distribute heat in a heated room, models with power from 9 kW to 20 kW during operation, continuously force air circulation even when the heating elements are turned off. This allows the air temperature to be equalized in different parts of the room.

The heaters have protection against overheating in the form of an automatic RESET function with simultaneous cooling - if the temperature of the outgoing air exceeds 105oC (the temperature is measured by a sensor), the STB thermostat will automatically activate: the heating elements will be turned off and the fan in the heater will work to cool the heating elements . The most common cause of this function is a power failure during the heater operation, causing the temperature inside the device to rise as a result of the fan stopping or turning the device off without cooling down for 3 minutes.
