AquaKond Split is the ideal solution for heating buildings where stricter regulations on fire prevention apply (workshops, woodworking plants, printing sites, textile and paper manufacturing plants, public and commercial buildings).

Combustion efficiency can reach 109%, (4 stars according to the Boiler Efficiency Directive 90/42/EEC - compliant with 2002/91/CE Directive) and assures consistent fuel savings if compared to traditional, non-condensing systems.


Each 70 kW boiler includes a whole range of safety, protection and control devices, fully compliant with I.S.P.E.S.L. standards.

The total heat requirement can be split across multiple units, thereby making the installation convenient and rational: thermal output can be managed on an area basis and new units can be installed when additional requirements arise.

AquaKond Split does not require any dedicated room for installation. Boilers can be installed outdoor, thus freeing indoor space.

PLUS heaters have been designed and developed by Apen Group's R&D department combining premix gas burner and microprocessor-assisted electronic control technologies. This results in a continuous adjustment of output power, and therefore of fuel consumption, to the heat request from the environment. When less heat is required, gas consumption decreases and efficiency tops 94,5%.

Energy savings over 20%: Modulation electronic card uses an advanced control system to keep delivery temperature steady at 41° C. This dramatically improves season average efficiency by considerably reducing thermal stratification.

Environment friendly technology: Everybody knows that carbon and nitrogen oxides are heavily responsible for atmospherical pollution. Premix burner optimises combustion and guarantees reduction of nitrogen oxide (NOx lower than 30 ppm) and absence of carbon monoxide (CO = 0).

User comfort: room temperature always constant and heat exchanger splits airflow in several layers preventing air stratification.

Their modular structure enables the user to heat only the chosen zones and also to perfectly suit the size of the rooms to be heated.

In ducted installation with centrifugal fan, Rapid heaters can deliver warm air through an air distribution system.



Minimising thermal inertia, Rapid warm air heaters guarantee energy savings if compared to other systems.

AirCooling units' evaporative cooling system presents an excellent solution.

The fan pad system cools the air using a natural principle: air flows through special wetted filters where it partially reduces its temperature through evaporation.

No refrigerating equipment is therefore required, thereby minimizing energy consumption, while large air volumes can be treated for the number of required air changes.

AirCooling cooler is an electrically powered equipment, also connected to the water supply system.

It is installed on the roof, on an external wall, or in a windows of the building or room where ventilation and fresh air are required.

Ducts have to be installed to connect the cooler to fresh air grilles which blow into the building.

The main advantages are:

As many air changes as required

Air cooling and filtering

Ventilation in colder periods

Customized or different management in different areas of the building

Low TCO, running and maintenance costs

Minimized energy consumption

No coolant gas - no environmental impact

Better environmental health.

The peculiar design of the hydraulic circuit of boiler and blowers allows installing indoor and outdoor units at different heights and distances.

By installing fittings for pipe connection in the upper part of the boiler you can:

Install outdoor boiler at a convenient height for maintenance and positioning.

Choose a suitable height for installing the blower in the room to be heated.

Shorten the distance between outdoor boiler and indoor blower, enhancing performances, reducing pressure drops and increasing water flow rate to the coil.
