Thermo E 200 / 320 2 Technical Data

2 Technical Data
Unless limiting values are defined, the technical data
should be understood with tolerances of ±10% common
for heaters at an ambient temperature of +20°C and at
nominal voltage.
Table 201 Technical Data
2.1 Electrical components
All heater components as well as the circulating pump and
the timer are designed for 24V nominal voltage. The
temperature sensor voltage is regulated by the control
unit.
NOTE
Circulating pumps must be assigned to the heaters
according to the flow resistance in the coolant circu-
lation system.
2.2 Fuel
Only fuels listed on the type plate as well as fuels
approved by Spheros may be used. The fuel use limita-
tions in the heater listed below must be observed.
– Diesel fuel according to DIN EN 590 and DIN 51628:
The limitations of use of the standard apply, hence
winter diesel down to -20°C, Arctic diesel down
to -40°C
– Light fuel oil according to DIN 51603 (above 0°C)
– Mixture of 70 Vol-% diesel fuel (winter diesel) accord-
ing to DIN EN 590 or DIN 51628 and 30 Vol-% Bio-
diesel according to DIN EN 14214: -5 .. -10 °C without
preheating system, -15°C with nozzle block preheater
and heated fuel filter (use limitations depending on
fuel quality).
At temperatures below 0°C commercially available winter
diesel should be used. This especially applies for fuel
extraction from a separate fuel tank.The use of lubrication
and flow improving additives is permitted. No negative
impact is known at time of the preparation of this work-
shop manual.
ATTENTION
The listed temperature ranges, hence minimum per-
missible temperatures strongly depend on the re-
spective fuel quality. In case of bad-quality fuel the
use limitations may deviate, e.g. in case of too high
water content.
When fuels are used, their respective limitations of
use must be observed and appropriate measures
(nozzle block preheater, electrically heated filter)
must be applied as needed.
In case fuel is extracted from the vehicle tank, the
vehicle manufacturer's mixing regulations shall
apply.

Max. continuous current of the circulating pump 8.75 A, max. peak current for 0.5 s duration = 90 A - We recommend the use of Spheros
circulation pumps for highest efficiency and reliability! In order to reduce starting currents the circulating pump can be synchronized by the
control unit for a short time period during activation.
Confirm compatibility in case pumps provided by different manufacturers are used!
