GENERAL DESCRIPTION
This versatile mobile electrical boiler is designed as a
robust heat generator for closed heating systems. Wa-
ter can be heated up to 85°C, for applications in both
residential (e.g. back-up boiler) and industrial environ-
ments (e.g. screed drying on working sites).
The E-Tech M can operate in a single-phase or three-
phase environment, with powers ranging from 3 to 36 kW.
It can be connected to a high-temp or low-temp heating
system, to an external hot water tank (heated through
primary circuit) or be used for screed drying.
The E-Tech M is equipped with an internal circulating
pump and with temperature sensors on the supply and
return circuits.
The standard built-in safety equipment are the following:
safety valve, automatic air vent, pressure sensor, double
high temp safety thermostats (60°C and 96°C), frost pro-
tection.
The operation parameters for heating and for screed dry-
ing can be set up using the user-friendly built-in touch con-
trol panel. Configurations can be saved and re-used indefi-
nitely according to operating environment. Operation data
and history are saved on an internal memory and can be
exported to an external drive for analysis and survey pur-
poses.
Thanks to its light weight, the E-Tech M can be easily
moved around and transported from one location to an-
other by one operator.
Maintenance and cleaning are also made easy through
quick removal/installation of components and easy
draining of the appliance.
Single phase (1 x 230 V) cables - 1,4 m (blue)
3 kW (1x16A)
6 kW (1x32A)
12 kW (1x63A)
Three phase 3x400V (+N) cables - 1,4 m (red)
