FITTINGS FOR REFRIGERANTING SYSTEMS FROM QUALITY OUR NATURAL DEVELOPMENT Achieved the goal of fty years working in the industry of Refrigeration and Air Conditioning, Castel Quality Range of Products is well known and highly appreciated all over the world. Quality is the main issue of our Company and it has a special priority, in every step, all along the production cycle. UNI EN ISO 9001:2008, issued by ICIM, certies the Quality System of the Factory. Moreover Castel Products count a number of certications in conformity with EEC Directives and with European and American Quality Approval. We produce on high tech machinery and updated automatic production lines, operating in conformity with the safety and environment standards currently enforced. Castel oers to the Refrigeration and Air Conditioning Market and to the Manufacturers fully tested products suitable with HCFC and HFC Refrigerants currently used in the Refrigeration & Air Conditioning Industry.

INDICE THREADED BRASS FITTINGS VIBRATION ABSORBERS All the products illustrated in this Handbook are submitted, one by one, to tightness tests besides to functional tests. Allowable external leakage, measurable during the test, agrees to the denition given in Par. 9.4 of EN 12284 : 2003 Standard: “During the test, no bubbles shall form over a period of at least one minute when the specimen is immersed in water with low surface tension, …”. PRESSURE CONTAINMENT All the products illustrated in this Handbook, if submitted to hydrostatic test, guarantee a pressure strength at least equal to...

THREADED BRASS FITTINGS APPLICATIONS All the ttings, shown in this chapter, are excluded from the scope of Directive 97/23/EC, as specied in the Guidelines 1/8 and 1/9, because they are piping components. ey are designed for installation on commercial refrigerating systems and on civil and industrial conditioning plants, which use refrigerant uids proper to the Group II (as dened in Article 9, Section 2.2 of Directive 97/23/EC and referred to in Directive 67/548/EEC). OPERATION e sealing system between the end of a male connection and a nut series 7010 , 7020 and 7030 requires a special...

VIBRATION ABSORBER APPLICATIONS e vibration absorbers are designed for installation on commercial refrigerating systems and on civil and industrial air conditioning plants. e function of this item is to avoid the transmission of compressor’s vibrations to the refrigerating system pipes, reducing the risk of damage and the noise level. e vibration absorbers can also compensate small thermal expansion of the piping. e vibration absorbers are classied “Pressure vessels” according Article 1, Section 2.1.4 of the Directive 97/23/EC and are subject to Article 3, Section 1.3 of the same Directive....

Care should be taken to allow sucient space for the vibration to avoid static compression or tension, after brazing on place. High speed of the refrigerant uid can produce vibration and noise phenomena. In this case it’s advisable to install a larger size of Vibration Absorber. e connection of the vibration absorbers to the piping is normally performed by a brazing process. e specic design and construction COMPRESSOR of vibration absorbers allows welding without particular protections to prevent overheating. WARNING! Ensure a gap corresponding to the 2% of the total length of the vibration...

ACCESS FITTINGS & VALVE CORES APPLICATIONS OPERATION All the access ttings and valve cores, shown in this chapter, are excluded from the scope of Directive 97/23/EC, as specied in the Guidelines 1/8 and 1/9, because they are piping components. ey are designed for installation on commercial refrigerating systems and on civil and industrial conditioning plants, which use the following refrigerant uids: R22 , R134a , R404A , R407C , R410A ; R507 proper to the Group II (as dened in Article 9, Section 2.2 of Directive 97/23/EC and referred to in Directive 67/548/EEC).
