General description
Purpose and field
applications
The Dantherm portable, duct type, heater model VA-M40 MK II is designed primarily to
supply un-contaminated, heated air to tents and other types of temporary or portable
shelters.
In addition, the heater is suitable for various field applications such as the warming up
of cold soaked equipment, engines, vehicles, aircraft, and other spot or space heating
requirements.
Principle
The heater operates on the indirect fired (clean air) principle thus ensuring that no com-
bustion products or fumes are introduced into the occupied spaces. The forced air sys-
tem provides the most rapid of warm-up capabilities. The units are essentially self-
contained requiring only a source of external electric power.
Performance char-
acteristics
The heater has a maximum heat output of 38 kW with a minimum combustion efficiency
of 85 %. The unit will start at temperatures as low as - 40 °C, and is factory set for oper-
ation to an altitude of 1,500 m Operation at higher altitudes requires minor field ad-
justment of the oil burner. The protective cabinet allows operation in snow or rainy con-
ditions.
Set up and opera-
tion
Set up and operation can be done by a single person. After start up, the heater functions
are automatic, thus permitting the item to be left unattended between periods of refuel-
ing. An optional remote thermostat may be connected to the heater for accurate tem-
perature control within a tent or other enclosure type. The control system also includes
a "vent" only position, which can be used to bring in fresh air, or circulate interior air,
even when heating is not required. The item is designed to be suitable for all standard
transportation modes.
Replacement of
parts
All critical sub-systems and component assemblies are replaceable as modular kits; this
ensures a repair capability at Unit level. No special tools are required for module re-
placement.
