TECHNICAL DOCUMENTATION
1. INTRODUCTION
Thank you very much for purchasing Reventon Group device. We would like
to congratulate you on excellent choice. Please read and keep this manual.
1.1 PRECAUTIONS
The buyer and the user of the air water heater Reventon Group brand should
read carefully the following instructions and proceed to the content
recommendations. Proceeding due to the following instruction guarantees
the correct usage and safety. In case of any doubts please contact directly
the producer Reventon Group sp. z o.o. The producer reserves the rights to make
changes to the technical documentation without previous notice. Reventon
Group sp. z o.o. is not responsible for the damages which occur due to improper
installation, not keeping the device in repair or using the device out of line.
The installation should be carried out by the professional installers, who possess
the qualifications to install these types of devices. The installers are responsible
for making the installation as instructed in the technical data. In case
of unserviceable please plug out the device and contact with the authorized
for repair person or the supplier. During the installation, use, service
and periodical inspections all regulations and safety rules must be followed.
1.2 TRANSPORT
During the acceptance of goods, it is needed to check the device to exclude any
damages. During the transport, it is needed to use the proper equipment,
it is necessary to carry the device by two people. In case of any damages please fill
in the damage report in presence of the supplier.
1.3 PACKAGE CONTENT
- Heater
- Operation and maintenance manual and warranty card
1.4 USE
Reventon Group Farmer MC-3S heating device is designed for heating 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 device 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
2.1 INTERNATIONAL 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
ź
to dangerous parts as well as against penetration of solids
ź
second characteristic digit – determines the resistance of the engine
ź
to the water ingress, its waterproofness
Fan motor of the Farmer MC has IP54:
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
2.2 CONSTRUCTION AND PRINCIPLE OF OPERATION
Casing: made of galvanized steel casing, powder painted in RAL 9005 color.
Additionally covered by LCE coating.
Air stators: made of galvanized steel casing, powder painted in RAL 7048 color.
It is possible to adjust manually the air stators to achieve the needed directio
of the air flow.
Heating coil: made of copper and aluminum. It is covered by LCE coating.
Supplied by distribution working fluid, which circulates through the coil
and releases heat to 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 MC-3S have a double row heat exchanger.
Axial blowing fan: made of galvanized steel. Fan has to ensure air flow through
the exchanger. It has a single- and three phase motor with the following
parameters: protection degree IP54, rate current 0,54-0,84 A (depending
on the operating mode). Diameter of the fan is 400 mm.
Rotating mounting bracket (optional equipment): enables the device
to be installed in several configurations (depending on the requirements)
and the unit to be rotated in a horizontal plane.
Fixed holders (optional equipment): made of steel, element for mounting
the device on a wall or ceiling. Solid and durable construction, possible
to assemble device in parallel on the angle 60° and 45°.
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.
TECHNOLOGY HAS THE FOLLOWING CERTIFICATES:
ASTM B1 17 salt spray test 1 0000 hours in heating/cooling cycles changing
temperatures between 60 °C and 5°C.
ASTM G 85 A1 Acetic Acid-Salt spray test to prove positive impact on coils used
in food industry.
ASTM G87 Same as G85 utilizing acidic SO2 electrolyte.
ASTM D552 Flexibility test, which investigates flexibility of coating to bond
to the substrate surface of coil.
ASTM G 85 A5 Indirect spraying of dilute salt and ammonium sulphate at 23°C
and followed by 1 hour exposure of dry air at 35°C. Test proving resistance in salt
containing environment and industrial applications.
ASTM G 21 that examines resistance to fungi. Important aspect for evaporators.
