Aquilo F4C

Trench convectors - Aquilo F4C

Trench convectors Aquilo F4C are especially designed for the in-floor mounting, and can be used for either heating or cooling. The heating or cooling element is a double-loop copper-aluminum heat exchanger, painted black, mounted inside a duct made of stainless steel in natural colour. Aquilo F4C convectors are equipped with noiseless centrifugal fans mounted inside the duct, by the exchanger, whose number depends on the exchanger’s length, providing the enforced air circulation and – with it – adequately higher heating or cooling efficiency of the convector. The fans are driven with 12 V motors. From the top the convector is protected with a crosswise masking grille made of any material available in the Manufacturer’s offer, to be ordered separately. The exchanger’s connection to the quadruple-pipe heating system is executed with four stub pipes with a G ½” internal thread. Obligatory electrical accessories, to be ordered separately, constitute a properly selected transformer (for surface or flush mounting), as well as a surface-mounted thermostat for the fan’s rotation regulation.

Non-standard versions available at request.
The order execution proceeds only after the graphic design has been accepted by the Client.

Grilles

In places where intense mechanical load on the grilles might occur (car dealers, gyms), the duralumin or stainless steel grilles are recommended.

The moisture content for beech or raw oak Aquilo convector grilles is approx. 10%. To enable the Clients coloring of their own choice, the grilles are not sold protected by preliminary varnishing.

However, while stored or after mounting, raw wood grilles can naturally lengthen even with 2-3 mm per each meter of the grille’s length, due to the natural process of moisture absorption from the ambient air. To avoid the adverse effects of this natural process, the grilles need to be protected against moisture. Painting with oil or varnishing eliminates the possibility of the negative effects of swelling or shrinking of the wooden grilles. In case grilles become moist, they should be varnished only after they become entirely dry and return to their required length, appropriate to the duct’s dimensions.

Note:
All Aquilo convectors if you need to apply them in swimming pools must be ordered in special version. This applies to a special version of stainless steel duct as well as other specially designed pieces of equipment. In the description of the type of heater and pool grille version should be added to the type of letter B. Eg: FMKB, F1TB, F1PB or PMOB, PMLB, PMZB and further details as to the basic version. Recommended performance grille for the version pool of duralumin.

    Installation of Purmo panel radiators in small open system installations ( up to 25 kW) is allowed provided the corrosion inhibitors are used.
    During the warranty period the radiators and their components with the faults originated from the manufacturer and reported not later than one month after having been discovered will be repaired or exchanged into new, free of defects devices.
  4. The guarantee is recognized when:
    • there is an evidence of purchase, that is the invoice, 
    • the radiators have been mounted in water central heating systems in compliance with the national technical regulations and standards, 
    • adhering to the requirements of the Guarantor included in „ Terms and conditions of Purmo panel radiators usage”.
  5. Maximal operating pressure in central heating installation for PURMO panel radiators may not exceed 10 bars (6 bars for Vertical radiators ) and the maximal service temperature is 110 °C.
    In high and high-rise buildings a zone distribution system must be applied. The tightness test must be carried out at the experimental pressure equal to working pressure in the installation, adding two bars, yet not lower than four bars. Maximal pressure during the installation tightness test shall be equal to 12 bars ( 8 bars for Vertical radiators). 
  6. The guarantee does not cover radiators mounted:
    • in central heating installation connected to a high temperature heat distribution network through a suction elevator or  pump mixing loop;
    • in swimming pool areas, car wash centers, laundries, slaughterhouses, public toilets, bathrooms or other rooms with high activity of corrosive substances in the air , as well as areas where the radiator is exposed on  permanent or temporary moistness – it does not refer to galvanized radiators , with additional anti-corrosive protection and guarantee for 6 years , yet not longer than 7 years since the production date
    • in central heating installations connected with the water- supply system without protective fittings, against backflows; 
    • in central heating installation with water removed  more frequently or for longer periods than advised in exploitation requirements; 
    • in steam installations ;
