TECHNICAL FEATURES
AND DIMENSIONS
The furnace is accessed through a burner support door fixed
to the generator by hinges; the door is internally coated with a
suitable layer of refractory cement and is fitted with flame light
and burner support plate.
The rear flue gas casing is fixed to the generator by bolts, is
internally insulated with insulating concrete and is fitted with
cleaning door.
The generator body is covered with a suitable layer of high den-
sity rock wool and externally covered with a painted sheet met-
al casing; this reduces the heat losses, improving the overall
performance.
The DĨATHER type diathermic oil boilers provide a maximum
temperature of use of 300°C with a thermal gradient of 40°C
between oil inlet and outlet.
NOTE:
The DĨATHER boilers are CE marked accord
-
ing to Directive 2014/68/UE (category I). Weld
-
ing procedures and devices are approved and
certified according to Standards EN 15614,
EN287 and UNI EN ISO 9606.
The design does not take account of fatigue
stress nor of damage due to earthquake or
other natural events.
The DĨATHER model diathermic oil boilers are of the type with
four principle helical tube bundle, with execution in two concen-
tric rings inserted in a fumes hermetically sealed sheet metal
cylindrical body.
The tubes constituting the tube bundle are made of "seamless"
quality steel.
The first "ring" characterises the furnace along which the flame
extends; the second "ring" originates a three flue gas pass path
which allows an optimal exploitation of the entire exchange sur-
face.
The base consists of electrowelded steel profile frame
