Thermal oil heaters

PIROBLOC thermal oil heaters are adapted to world-wide standards. We produce a large selection of thermal fluid heaters, customized for our :customers' needs

Horizontal or vertical execution. There is no functional difference between a horizontal thermal oil stove and a vertical thermal fluid stove, with the choice being made according to the available space and height, .and ease of maintenance

Our hot oil boilers can work with liquid fuel (fuel oil, diesel fuel) and / or

.(.gas (natural gas, propane, etc

Thermal oil boiler is the main component of a thermal fluid heating system, where the thermal fluid is heated and distributed to provide .energy to various energy users within a closed circuit

.Features: Automatic oven activation and indirect control

Advantages of a hot oil heating system

safety

Our thermal fluid heaters operate without pressure and water. This avoids typical problems related to steam heating systems, such as leaks, .corrosion, water treatment, etc

Thermal oil heaters require low maintenance

Fuel savings up to 20% compared to steam heating systems. Thermal fluid system consists of a closed circuit with minimal energy leaks. At least .90% of the fuel is used in the heating process

efficiency

Hot oil heating systems are very efficient due to temperature uniformity .throughout the production process

Operation of thermal oil heaters

Initially, the thermal fluid rolls in the outer coil (where the
heat is transferred almost exclusively by convection) before
moving to the inner coil (where the heat is transferred
almost exclusively by radiation), thus achieving excellent
.energy efficiency

The inside of the front cover closes the exhaust gas
between the coils, and has holes for pipe passage, each pipe
connecting to the general collectors, which are connected to
.the outer circuit by flanges

This lid also closes the combustion chamber where the
burner is fixed. It is equipped with an access door to the
.combustion chamber if necessary
PIROBLOC are one of the pioneers in the production of

thermal oil boilers. Extensive knowledge of this technology

and our belief in innovation have enabled us to develop our

design, which takes into account all important technical parameters, as well as offering a vertical configuration that is a perfectly valid alternative to the conventional horizontal configuration in the market.

Our thermal oil heaters are cylindrical, arranged to raise the
temperature of the thermal fluid in the circulation of two
concentric coils by combustion of liquid fuel in the burner
.located in the front wall
High-density rock wool insulation between two casings

ensures low temperatures (30-40 ° C) in the outer casing,
thus achieving minimal structural losses and preventing
.accidental burns from the boiler
The burner flame is projected into the combustion

chamber, which is designed and built according to the
geometry of the flame. Combustion gases swirl around the
coils at high speed and then the direction of the gases
changes and again they rotate at high speeds and swirl
between two coils on the front cover, where they change

direction again until evacuated by a chimney at the end of

.the stove

A coil consists of two, three, four or more stages depending on the model; For the rapid flow of thermal fluid is essential for good heat transfer to prevent the coil piping from being blown out.
