FLOOR STANDING HEATER PK-N

A NEW HEATER

CONSTRUCTION FEATURES

Apen Group has redesigned the new series of floor standing heaters PK-N, in order to improve the technical performances and consequently the safety, the efficiency and the quality, meeting the requirements of customized solutions and respect for the environment.

The outfit has been improved thanks to the aluminium frames that, placed on the panels, make the geometric figures more harmonious.

Therefore they fit in the installation ambient, both industrial and civil.

PK-N: THE HEAT THAT LASTS IN TIME MODELS: PKA-N PKE-N PK-N heaters can be supplied in two versions: • PKA-N: floor standing warm air heaters for indoor installation • PKE-N: floor standing warm air heaters for outdoor installation

A) Combustion circuit • Stainless steel AISI 430 combustion chamber, with high exchange surface (with higher volume in respect to the thermal load). Thanks to its particular shape, it assures low thermal loads and an uniform heat distribution.

• Reverse flame combustion chamber, with three pass combustion circuit, completely welded, to assure a long operating life.

• High efficiency stainless steel AISI 304 heat exchanger constituted by a conic section tube heat exchanger with aerodynamic profile.

The PKE-N heaters differ from the PKA-N in the protecting cover, that guarantees to the burner, the electrical and safety components, inside of it, a complete weather-protection.

• Patented tube heat exchanger (Patent n° MI94U00260 dd. 08th April 1994).

The panelling structure of the whole heater (burner casing included) warrants an IP44 protection degree.

• One front and four rear inspection panels on the heat exchanger made in stainless steel AISI 430.

• Exchanger tubes and plates are T.I.G. welded.

• Insulation of the inspection panels made in ceramic fibre.

• Sight glass with combustion chamber pressure tap.

• Insulation panel for the burner plate made in mineral fibre.

HOW TO CHOOSE THE RIGHT MODEL Our large range of models can satisfy any requirement: • PKA-N: indoor floor standing heater: -13 models with capacity from 26 kW to 920 kW; -three available static pressure configurations, that allow the choice among a total of 37 standard versions.

• PKE-N outdoor floor standing heater: -13 models with capacity from 26kW to 920 kW;

Front

Side

-two available static pressure configurations, that allow the choice among a total of 24 standard versions.

WORKING PRINCIPLES C APACITY R ANGE The working principle of the PK-N Heater is very simple.

CAPACITY

The ambient air (7) to be heated is sucked by the centrifugal fan (5) through the aspiration grille (1), and it is heated (8) passing on the combustion chamber (3) and on the heat exchanger (4).

The hot air (9) is then thrown in the ambient, directly by an outlet plenum, or through a duct system.

The heater has the following safety devices(10): fan thermostat and safety thermostat.

All main electrical components are fitted in the electrical board (6) .

MODELS

Upon request, the heater can be supplied with burner (2).

To choose the right model, the following items must be considered: • the use (heating, process plants or other), • the kind of operation (seasonal or continuous), • the kind of coupled burner (on/off, two stages or modulating)

AVAILABLE STATIC PRESSURES

WORKING FIELD

The standard available static pressures are: -version 00A (only for PKA-N), installation with plenum, where there is no need of high air pressure.

This allows the use of motor with lower speed, consequently assuring lower running costs, thanks to a saving in the consumption, and higher comfort thanks to the low level noise; -version 10A, with medium available static pressure values, for installation with duct systems when no particular pressure is needed; -version 20A, with high available static pressure, for installations with articulated duct systems or with high air speed.

Each heater has a wide working field, that goes from the minimum power, with a maximum certified efficiency from 93.1% to 94.6%, to the maximum power with a minimum efficiency from 87.5% to 90.8%.

The use of an oversized heater with regard to the ambient heat request, allows a higher plant efficiency. As you can see from the following diagram, should the ambient heat request be of 190 kW, using a PKA190N heater, the efficiency is of 90.5%; whereas using a PKA 250N, the efficiency goes up to 92.5%.

On specific request, it can be supplied with the air throw on two long sides and one short side.

In case of particular needs, Apen Group can design and manufacture plenum custom-made.

SAVING The PK-N heaters guarantee a real saving according to: • installation: if positioned directly in the ambient to be heated with air distribution through plenum, the plant costs are very low; • operation: high efficiency and heating of the ambient in short time guarantee efficiency and energy saving; • service: the maintenance operations are easy and fast.

Air filter The air filter has been designed and manufactured in modacrilic fibre, fire-proof class 1, can be used in continuous service up to a maximum temperature of 80°C and has an average efficiency equal to 85% (according to the EN 779 Norm) corresponding to class G3.

The air filters, in the standard versions, have been dimensioned to make the aspiration only from one side.

In case of particular requirements, for example horizontal or downflow installations, contact Apen Group to obtain the right sizing.

MAINTENANCE All the maintenance operations are particularly simple and fast and guarantee the heater's efficiency.

To reach the heat exchanger, it is sufficient to take off the front inspection panel.

The fan cleaning can be made with a compressor and with a vacuum cleaner.

The filters can be regenerated through the cleaning with compressed air.

It should be noted that in the installations with duct systems, the filter positioned inside can be removed for servicing and maintenance without any need to disconnect the ducts.

Discharge The heater is a B23 type, that is an appliance without draught switch and with burner fan before the heat exchanger.

The heater can be connected both to flue ducts and chimneys.
