Filters and liquid/humidity indicators are designed for installation on commercial refrigeration systems and civil and industrial air conditioning systems employing Group II refrigerants.
Filter driers are available in a hermetically sealed version or with a solid exchangeable cartridge.
Hermetically sealed filters are supplied in the standard drier version, series 43, anti-acid series 42, bi-directional flow series 46, with indicator series 41 and mechanical series 45.
Filters with a solid exchangeable cartridge are available in packages of 1 to 4 standard drier, anti-acid or mechanical cartridges.
Liquid/humidity indicators are available with welded or flare connections in a monitoring only version, series 38, or monitoring + humidity detection, series 37 and 39.

Series 3030 and 3060 valves are safety accessories according to the definition contained in Directive 97/23/CE and are subject to the requirements of the Directive.
These valves are conventional unbalanced direct load safety valves.
Series 3070 rupture discs are pressure limiting devices which open at a certain pressure and cannot be reclosed.

Threaded brass connections
Designed for installation on systems using the following refrigerants: R22, R134a, R404A, R407C, R410A; R507 in Group II (as defined in Article 9, Point 2.2 of Directive 97/23/CE, with reference to Directive 67/548/CEE). Contact Castel’s Technical Office for information on specific applications with refrigerants which are not listed above but do belong to Group II.

Vibration isolators
Vibration isolators are installed on commercial refrigeration and civil and industrial air conditioning systems to eliminate transmission of vibrations generated by the compressor to the pipes in the circuit. They also reduce noise and compensate for slight thermal dilation.
Vibration isolators are designed for installation on systems using the following refrigerants: R22, R134a, R404A, R407C, R410A; R507 in Group II (as defined in Article 9, Point 2.2 of Directive 97/23/CE, with reference to Directive 67/548/CEE). Contact Castel’s Technical Office for information on specific applications with refrigerants which are not listed above but do belong to Group II.

Access fittings and mechanisms
All filling fittings and mechanisms illustrated here are excluded from application of Directive 97/23/CE in that they are classified as piping components, as stated in Guidelines 1/8 and 1/9.
Access fittings permit quick, economical creation of a filling or bleed point. Once filling or bleeding operations have been completed, a sealed cap (code 8392/A or code 8391/A) prevents all possible refrigerant leakage.
