1.4 USE
Reventon Group Farmer HCF heating devices are designed for heating or cooling
surfaces in which aggressive conditions prevail, i.e. high content of acids,
ammonia and high concentration of dust. However, heaters should not be used in
highly corrosive environments for aluminum, copper and steel. The devices
should also not be installed in rooms where they would be exposed to the high
humidity or direct water action, exceeding the fan's resistance to water
penetration (see IP protection degree).
2. DEVICE CHARACTERISTICS
2.1INTERNATIONAL PROTECTION DEGREE IP
Determines the tightness of the electrical device (fan motor), which is defied
by two digits:
ź first characteristic digit - specifies protection of the device against access
to dangerous parts as well as against penetration of solids
ź second characteristic digit – determines the resistance of the engine
to the water ingress, its waterproofness
ENG
TECHNICAL DOCUMENTATON Fan motors of the Farmer HCF series have following IP:
5 - protection against access to hazardous parts by wire with a diameter of 1 mm
or more and against dust in quantities which might impair the proper functioning
of the equipment;
4 – protection against splashes of the water from any direction.
6- protection against access to hazardous parts by wire with a diameter of 1 mm
or more and against dust (total dust tightness);
5 – protection against stream of the water (12.5 l/min) from any direction
2.2 CONSTRUCTION AND PRINCIPLE OF OPERATION
Casing: made of expanded polypropylene (EPP). This material is characterized by
low density (light weighted) and high chemical and physical resistance.
It has an excellent sound and thermal insulation properties. Moreover, material
is environmentally friendly and "green", i.e. 100% recyclable.
Air stators: made of polypropylene PP. It is possible to adjust manually
the air stators to achieve the needed direction of the air flow. There are also
versions with confusor (increased airflow range) or with diffuser 360° (better
mixing of supplied and room air).
Heating coil: made of copper and aluminum. It is covered by LCE coating.
Supplied by distribution medium (heating or cooling), which circulates through
the coil and releases or extracts heat from the air. The coil has the following
technical parameters: the maximum temperature of the heating factor is 120°C;
maximum pressure 1.6 MPa; headers diameter ¾”. Farmer HCF series have
a double row heat exchanger.
Axial blowing fan IP54 (Farmer HCF IP54-3S): made of galvanized steel.

2.3 LCE COATING
The coating technology is based on immersion of the exchanger in the liquid LCE,
which allows ptotection of the whole surface of the exchanger. The LCE coating
is waterproof and protects the heater exchanger from corrosion, mould
and bacteria without compromising heat transfer efficiency. It is flexible enough
not to be teared during thermal expansion of metal parts.
Periodic maintenance guarantees the resistance of the LCE coating
to the following concentrations of chemical factors:
In addition the above LCE COATING demonstrates high resistance to fumes
of the following: Lactic Acid, Oxalic Acid, Humic Acid, Saltwater and NOx.

could take place empty the device out of water
- after the turn off, the elements of device may be warm
-after operating time of the device, please utilize it concerning the local norms
and regulations
- it is recommended to clean the device periodically (at least once per month):
ź heating coil blow with compressed air
ź fan casing and blades clean from dirt
- for installation of the device in a room where is high dust concentration,
the periodic cleaning should be performed much more often, not allowing
the heat exchanger to 'clog’
- failure to comply with cleaning obligations may have a negative effect
on technical parameters of the device and lead to loss of warranty
- if the device is not used for a longer time disconnect the power supply
- air stators of the device have to be open in at least 30% before first start:
