REMKO GPM
Description of the unit
Definition of the equipment
Pursuant to EU Directives, the
equipment is defined as:
"Gas fan-assisted air heater
without flow-operated safety
device, equipped with a fan in
front of the heat exchanger".
The equipment is a fully-
automatic, directly-lit, fan-assisted
air heater for wall and ceiling
installation. It can be fuelled with
natural gas or liquid gas.
The equipment is used for
continuous and temporary
heating of open and closed spaces,
e.g. in:
halls, workshops
greenhouses,
storage rooms, etc.
Classification of the equipment
The equipment was classified by
the European standardised
regulations EN 437 and EN 1020
according to:
The gas category:
determination according to the
type of gases with which they may
be operated.
For Germany DE II2ELL3B/P
The gas type:
the burner can be operated with
gases of the second family (natural
gas - group H and L) and with
gases of the third family (butane
and propane).
The type of gas fireplace:
differentiation according to the
possibilities of the discharge of the
combustion products or the supply
of the combustion air.
(ambient-air-dependent/
independent)
Additional notes can be found
in the chapter "Installation of
the flue gas evacuation and the
combustion air supply".
Design of the equipment
The exterior cladding of the
equipment is made from coated
steel sheet, which guarantees
durability.
The outlet grid is found in the
front section.
In order to ensure an optimal
distribution of warm air in the
installation location, the horizontal
fins of the outlet grid can be
manually adjusted.
On the rear side of the equipment
you will find the fan(s) with
protective grid, the connection
nozzles for the removal of
the exhaust and supply of the
combustion air, the gas connection
nozzles, the cable passages for
the electrical lines as well as the
plug connection for the mains
connection. In the right-hand side
section the necessary components
for the control and safety are
found behind the inspection door,
including:
- the electrical circuitry with the
cabling
- the control electronics
- the gas valve
- the modulating gas burner
In the interior of the equipment,
directly in the circulation air flow is
the combustion chamber with heat
exchanger.
The combustion chamber is
manufactured entirely from Inox
stainless steel, grade AISI 430. For
the purpose of higher resistance to
corrosion from damp vapours, Inox
stainless steel, grade AISI 441 is
used for the heat exchanger.
The special form and the large
surface area of the combustion
chamber and heat exchanger
guarantee a high level of efficiency
and long service life.
The gas burner is likewise
manufactured entirely from special,
mechanically-processed stainless
steel.
Function of the equipment
The modulating, gas fan-assisted
air heater of the GPM series has
been developed for the heating of
industrial and commercial spaces.
The electronic control of the
equipment continuously regulates
the heat output between minimum
and high-output according to the
actual heat requirement.
With the pre-mix and modulation
technology, efficiency of up to
94% can be achieved.
The nominal heat output of the
REMKO GPM series lies between
11.8 and 71.5 kW.
The equipment consists primarily
of the combustion chamber with
heat exchanger and the fan(s).
The ambient air is suctioned
in by the fan(s) and efficiently
channelled through the
combustion chamber with heat
exchanger. The combustion
chamber is heated by the gas
burner operation and releases its
heat to the air flowing past. The air
heated in this manner is blown out
of the front side of the equipment
through an adjustable outlet grid.
The operation of the equipment
as intended is only possible with a
connected control unit, e.g. ATR-6
(accessory).
The units are not suitable for
the heating of living spaces or
the like.
