All for one and one for allAskoll aims at improving quality of life considerably through the creation of increasingly inno-vative products that respect the environment and provide significant energy savings in addi-tion to better performance.Innovation applied to the heating field has resulted in a unique product and a true turningpoint in circulation pumps for domestic and residential use: T R O N I C

T R O N I C provides formidable advantages:

A universal product

Energy savings

Ideal performance

Reliability

Ease of installation and regulation

1 A universal product: one for all

Askoll introduces a new standard for circulation pumps: T R O N I C , one circulator to coverthe entire operating field from 1 m to 6 m total head.

● Maximum easiness in identifying the most suitable circulator for each individual installation

● No possibility to commit installation errors

● No subsequent lost time for the installer

One for all! T R O N I C is characterized by an “infinite”number of operating curves to satisfy everyinstallation need (from a simple monotube to more modern and sophisticated systems) alwaysproviding optimal performance: a single pump replaces entire ranges of traditional circulators.

2 Energy savings: up to 80% less

T R O N I C CLASSE A for energy consumption!

3 Ideal performance

Energy consumption has never been this low:ggrreeaatt ppoowweerr iinn jjuusstt 66 WW..T R O N I C is a highly energy-efficient variable-speed pump: in fact, atequal hydraulic performance it absorbs less electricity up to peaks of80%, compared to both traditional three-speed pumps and moreadvanced electronic circulators.

This translates into exceptional energy savings, oovveerr 225500 kkWWhh peryear: in fact, a circulation pump is estimated to operate for about6,000 hours a year. In addition to protecting the environment, thereare obvious economic advantages from using a T R O N I C pump.

An infinite number of stable operating curves, with constant pressure in the working field

OPTIMAL HEAT AND NOISE CONDITIONS

T R O N I C is the ideal solution for every domestic and residential heating system.When a traditio-nal three-speed circulator is installed, it is not always possible to run the pump at the optimalsystem working point (the pump will run at either point P1 or point P2,depending on the regu-lation).

The advantage of an infinite operating curve is obvious:it is possible to select the exact workingpoint over the entire field of use, in every case.

Moreover the performance of T R O N I C pump are very stable: the curve selected does not sufferany translation: it doesn't vary with the temperature of the liquid pumped or with changes inother operating conditions. It is possible to determine the optimal working point with certainty,confident that this will not vary until the system's pressure drops are changed.

NO MORE ROTOR LOCKING

T R O N I C integrates special techniques designed to limit pump locking problems:the patented “square chamber”eliminates the possibility of operation interruption since impuri-ties inside the rotor chamber find a preferential accumulation area in special cavities in thechamber itself;

T R O N I C is equipped with a special cable gland: just connect the two conductors to the ter-minal board and connect this latter to the compartment provided on the connectioninterface box.

Advanced electronic devices detect any rotation difficulty and, if neces-sary, repeatedly start the motor to always guarantee correct start-up.

The pump works with minimum performance.The maximum head is about 0.6 m with a flow rate of 0 l/h while the totalhead is about 0.5 m with a flow rate of 1.000 l/h

Pump performance are equivalent to the performance of a traditionalpump with a maximum head of 2 m.The total head is about 1 m with a flow rate of 1.000 l/h

Pump performance are equivalent to the performance of a traditionalpump with a maximum head of 3 m.The total head is about 2 m with a flow rate of 1.000 l/h

Pump performance are equivalent to the performance of a traditionalpump with a maximum head of 4 m.The total head is about 3 m with a flow rate of 1.000 l/h

Pump performance are equivalent to the performance of a traditionalpump with a maximum head of 5 m.The total head is about 4 m with a flow rate of 1.000 l/h

The pump works with maximum performance.Pump performance are equivalent to the performance of a traditionalpump with a maximum head of 6 m.The total head is about 5 m with a flow rate of 1.000 l/h

Even the regulation of the pump is very simple and intuitive:the desired operating curve is selec-ted by turning the regulator with a screw driver.

Make sure that the pressure at the pump's intake is at least equal to the minimum value requi-red. It is recommended not to start the pump before having filled and drained the hydraulic cir-cuit. It is possible to drain the rotor by removing the drain plug on the motor. Possible connec-tions box positions:

The special cable gland allows a fast electrical connection: connect the two (orange) conductors tothe terminal board and insert the connector in the compartment on the connection box.

T R O N I C pumps have to be always installed with the motor shaft horizontal.
