Canne fumarie singola parete SP - SP Single wall flues 5. I camini singola parete La produzione dei sistemi a singola parete trova la sua principale applicazione sia nel risanamento edilizio e nell’adeguamento di vecchi condotti fumari alle nuove esigenze impiantistiche, che nell’evacuazione dei prodotti di ventilazione; la produzione dei sistemi singola parete segue inoltre la crescente diffusione di generatori di calore a tiraggio forzato e a condensazione, le cui caratteristiche rendono essenziale la garanzia di tenuta dei condotti. In base alle norme di prodotto che regolano la marcatura CE sui camini metallici singola parete (EN 1856-1, EN 1856-2), i sistemi a singola parete possono essere utilizzati sia come condotto fumario di intubamento all’interno di camini esistenti o asole tecniche, sia come sistema camino all’esterno degli edifici se applicati a servizio di caldaie a condensazione con emissione in atmosfera di fumi in pressione positiva e a basse temperature (circa 40÷50°C). Inoltre i camini singola parete possono anche essere utilizzati nel tratto di collegamento sub-orizzontale (canale da fumo) tra generatore di calore e camino verticale. La tipologia dei prodotti in acciaio inox viene distinta in funzione del livello di tenuta alle pressioni e della classe di temperatura di utilizzo. Per il funzionamento in pressione positiva (classe P1) e con temperature di esercizio fino a 200°C la Roccheggiani propone sia il modello SPG realizzato in acciaio inox Aisi 316L (1.4404), sia il modello SPGV realizzato in acciaio inox Aisi 316L verniciato color rame brunito (ramato); entrambi i modelli sono provvisti di una guarnizione siliconica a “triplo labbro” che assicura una perfetta tenuta tra i singoli elementi. Il modello SP, disponibile in acciaio inox Aisi 316L (1.4404) e su richiesta in acciaio inox Aisi 304 (1.4301), rappresenta la soluzione complementare al modello SPG per centrali termiche caratterizzate da elevate temperature fumi, caminetti e stufe a legna, ed è adatto per il funzionamento in pressione negativa (classe N1) e con temperature di esercizio fino a 600°C. I modelli SPG ed SP sono costituiti da elementi rigidi, adatti quindi alle applicazioni con percorso del condotto fumario ben definito e lineare; per il risanamento di condotti fumari esistenti con andamento irregolare, la Roccheggiani dispone della serie Flex tubi flessibili, il cui prodotto di punta è il modello TDX a “doppia struttura” con parete interna liscia, realizzata in acciaio inox Aisi 316L (1.4404). A completamento della gamma prodotti singola parete sono disponibili: - i condotti fumari in polipropilene PP, composti da elementi rigidi (modello SPL) e flessibili (modello PPS), impiegati nei sistemi intubati alimentati da apparecchi a condensazione. - i condotti fumari in acciaio verniciato color nero (modello SPV/SPGN) utilizzati per l’evacuazione fumi da stufe e caminetti a legna. Il presente catalogo costituisce un supporto tecnico ed informativo sulle caratteristiche della serie singola parete: grafici dimensionali, modalità di installazione, schede tecniche, disegni tecnici, forniscono tutti i dati necessari per realizzare un sistema fumario conforme alle normative vigenti. differ on the basis of the pressure level and of the working temperature class. For positive pressure (class P1) and low temperature (up to 200°C) working conditions, Roccheggiani offers both the SPG series, made of AISI 316L (1.4404) stainless steel and SPGV series made of antique finish copper painted AISI 316L stainless steel; both the models are provided with a “triple lip” silicone gasket which ensures a perfect tightness between separate elements. The SP series, available in AISI 316L (1.4404) stainless steel, and, on request, in AISI 304 (1.4301) stainless steel represents the complementary solution to SPG series for thermal plants with high fumestemperature, fireplaces and wood stoves, and is suitable for negative pressure (class N1) and high temperature (up to 600°C) working. The SPG and SP series are made up of rigid elements, therefore suitable for applications in which the course of the skylight shaft is well defined and linear; for the renewal of pre-existent skylight shafts with irregular courses, Roccheggiani provides the Flex flexible flues, whose leading product is the “double structure” TDX series, with smooth internal wall, made of AISI 316L stainless steel. The single wall product range also includes: - PP polypropylene flues: rigid liners (SPL series) and flexible liners (PPS series), for ducted systems serving condensation boilers. - black painted stainless steel flues (SPV/ SPGN series), for fumes exhaust from wood stoves and fireplaces. This catalogue represents a technical and informative support providing the characteristics of the single wall series: dimensional graphs, installation instructions, specifications and designs provide all the necessary information to set up a flue-system in conformity with the provisions in force. 5. Single wall flues The single wall system products find their main application both in the building renewal and adjustment of old chimneys to the new plant require-ments and in the ventilation vapour exhaust; moreover, the single wall system products follow the growing spread of forced-draught and condensing heat generators, the features of which make it essential for flues to be sealed. According to the product standards which regulate the CE mark on the single wall metal chimneys (EN 1856-1, EN 1856-2), the single wall systems can be used both as a liner inside the old chimneys or the skylight shafts, and as a chimney system on the building outside if applied on condensation boilers with emission in atmosphere of low temperature fumes (about 40-50°C) in positive pressure. Moreover the rigid single wall flues can also be used in the sub-horizontal linking tract (connecting flue pipe) between the heat generator and the vertical chimney.
