Flash coil steam generators of the series UNI-MATIC
(UM) with forced circulation guarantee a steam
production range between 300 and 3000 kg/h; design
pressure is up to 12 bar.
Models of the steam generators series UNI-MATIC:
• UM 30: up to 300 kg/h
• UM 50: up to 500 kg/h
• UM 100: up to 1.000 kg/h
• UM 150: up to 1.500 kg/h
• UM 200: up to 2.000 kg/h
• UM 300: up to 3.000 kg/h
UM-UNIMATIC UM flash coil steam generators’ fields
of application are laundries, texile industry, food &
beverage, rubber, cellulose industry, agrotechnology,
woodworking and others.
UNI-MATIC UM generators are supplied as packaged
units, complete with all necessary equipment and
ready to be connected to site utilities.
As optional, an air preheater can be purchased
additionally to the steam generator.
Preheater enables the boiler to increase efficiency by
2%, therefore reaching 90% at full load.
UM model reaches operating conditions 2-3 minutes
after ignition of the burner.
UNI-MATIC model UM is available both in vertical and
horizontal version - UM compact design is also suitable
for small plants, although always guaranteeing high
quality performances.
UNI-MATIC UM generators are deisgned and produced
according to ISPELS code, PED directive 97/23/CE

Figure 5
Control panel for UNI-MATIC UM steam generator.
•Two versions: vertical and horizontal
•Maximum efficiency and high reliability
•Easy maintenance. The upper cover facili-
tates inspection and cleaning of the combus-
tion chamber and the internal parts of the
steam generator.
•Fast to reach operating conditions. Thanks
to the absence of thermal inertia, UNI-MATIC
UM steam generator is highly efficient in peri-
odic processes. It takes 2÷3 minutes to reach
operating condition after burner ignition.
•High reliable supply of feeding water.
Feeding pump flow sections are made of
Kevlar, a syntetic composite material which
guarantees maximum reliability and efficient
supply of feeding water.
•Easy-to-use and reliable automatic combus-
tion regulation with the following regulating
types:
• “on/off” regulation of gas fuel feeding
to the burner, burner air vent and feeding
water pump. Liquid fuel supply to burner
nozzle is achieved through electromagnetic
opening/closing valve.
• two-stages regulation (1st stage - min.
50%, 2nd stage - 100%), through regulation
of the amount of air and gas in the com-
bustion chamber, regulation of feed wa-
ter supply with two-position valves on the
fuel, air and water lines combined with on/
off regime of water and gas supply. Liquid
fuel supply to burner’s nozzle is achieved
through an opening/closing valve.
modulating regulation of steam produc-
tion with 30-100% range, achieved with an
electronic control of air and fuel supply and
servocontrolled valves. Feeding water sup-
ply is regulated through plunger pump with
frequency transformer. Liquid fuel oil sup-
ply to burner’s nozzle is achieved through
opening/closing electromagnetic valve with
fuel pressure regulation through a bypass
valve.
•Safety. The quantity of water, and thus steam,
is limited, allowing therefore a high level of
safety for personnel if compared to standard
steam boilers types.

The generator must be supplied with water with
hardness less than 0.1° F made up of the condensation
recovery and the make-up water softened by a
purifier (cation resin) or demineralised. The water
supply must always come from the supply tank; a
direct connection to the mains water or to the purifier
is not allowed.
The suction piping must be as straight as possible
and its diameter must be larger than that of the
connection on the pump (see connection diagram).
The supply water must be at a temperature of at least
70° C as lower temperatures cause deterioration in
the generator coils.
If the water temperature is lower than the value
indicated above the supply water must be heated.
The tank capacity must be adequate for the boiler
capacity and normally at least the same as the
consumption of an hour operation at maximum load.
The tank must be fitted with a drainage tube with
cock direct to the sewers for regular drainage and to
empty the tank for cleaning.
Water pump must not suck from the bottom of the
tank but slightly higher to avoid the entry of impurities.
If the oxygen scavenger is required please refer to
the technical specifications of the product in use.
Total hardness Less than 0,05 °F
pH 8.5-10.0
Alkalinity Max 1000 ppm
Silicone (Si O2) Max 100 ppm

Water supply specifications. In order to maintain
its best performance the steam generator must
be supplied with water conforming to the below
specifications.

Table 4
Feedwater Quality Requirements for best UNI-MATIC UM operation and preservation
(a) with copper alloys in the system the pH value shall be maintained in the range be from 8.7 to 9.2
(b) with softened water pH value >7.0 - see the manual of the boiler
(c) If the operating pressure is <1 bar, the max total acceptable hardness should be 0.05 mmol / l
(d) Instead of observing this value at intermitted operation or operation without deareator if forming agents and/or excess
of oxygen scavenger shall be used.
(e) Organic substances are generally a mixture of several different compounds. The composition of such mixtures and
behaviour of their individual components under the conditions of boiler operation are difficul to predict.
Organic substances may be decomposed to form carbonic acid or other acidic decomposition products which increase the
acid conductivity and cause corrosion or deposits. They also may lead to foaming and/or priming which shall be kept as
low as possible.

GENERAL COMMENTS
The Generator must be installed on a rigid, levelled base, preferably on a concrete slab, in a room which
ensures adequate access to all the equipment and for the personnel.
The boiler room must comply with the prevention standards in force and must be dry, clean and well ven-
tilated.
Good ventilation is essential to supply enough air for combustion and a temperature which is suitable for
the regular operation of the electrical equipment, in any case not higher than 35-40°C.
The boiler room must have at least two constantly open air inlets, one of which as close to the fan as pos-
sible.
The boiler room must be high enough for the coil to be taken out.
Connections to be made
Make the following connections to start the generator:
• Chimney pipe to drain the fumes from the boiler outlet to the outside.
• Steam piping at the distribution system.
• Water piping at the water/condensation collection tank.
• Humidity separator (if fitted) drainage piping.
• Safety valve drainage piping.
• Boiler drainage piping.
• Fuel piping to the burner.
• Electricity to the panel.
!INSTALLATION OUTSIDE IS ABSOLUTELY FORBIDDEN, EVEN UNDER A ROOF
UNLESS THE GENERATOR HAS BEEN SPECIALLY MADE FOR THIS PURPOSE
!DURING INSTALLATION ALWAYS MAKE THE HYDRAULIC CONNECTIONS FIRST
AND THEN THE ELECTRICAL CONNECTIONS.
