DEHYDRATION OF REFRIGERANTS Among contaminating agents causing serious damages to refrigerating systems, moisture plays a major role. Its presence, even possible in the refrigerating system, is due to many factors: - inadequate or insuciently prolonged vacuum before refrigerant charging - oil used for topping up remained exposed to air humidity - refrigerant used for subsequent additions contained in non dried vessels - sealing defects especially in systems not designed for operation at low temperatures High temperatures combined with humidity give rise to complex phenomena enhancing acid...

LIQUID INDICATORS & MOISTURE-LIQUID INDICATORS Approved by Underwriters Laboratories Inc. APPLICATIONS e indicators, shown in this chapter, are classied “Pressure accessories” in the sense of the Pressure Equipment Directive 97/23/ EC, Article 1, Section 2.1.4 and are subject of Article 3, Section 1.3 of the same Directive. 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...

CONSTRUCTION New liquid indicators, series 38, and new liquid/moisture indicators, series 39, are manufactured in a total hermetic construction to avoid any possible refrigerant leaks. e glass “lens” , with its proper gasket, is housed into the brass body and is xed in this seat with an edge calking operation. e main parts of the indicators are made with the following materials: - Hot forged brass EN 12420 – CW 617N for body - Copper tube EN 12735-1 – Cu-DHP for solder connections - Glass for lens - PTFE for outlet seal gaskets Liquid/moisture indicators series 3770 , 3771 , 3780 and 3781...

ANTI-ACID SOLID CORE FILTER DRIERS WITH MOLECULAR SIEVES AND ACTIVATED ALUMINA – SERIES 42 Approved by Underwriters Laboratories Inc.. SOLID CORE FILTER DRIERS WITH 100% MOLECULAR SIEVES – SERIES 43 Approved by Underwriters Laboratories Inc. APPLICATIONS e lters, shown in this chapter, are classied “Pressure vessels” in the sense of the Pressure Equipment Directive 94/23/EC, Article 1, Section 2.1.1 and are subject of Article 3, Section 1.1 of the same Directive. ey are designed for installation on commercial refrigerating systems and on civil and industrial conditioning plants, which use...

e shape of the block is designed in order to oer the maximum possible surface area to the incoming uid. e internal cavity is also positioned in such a way as to have a uniform wall thickness. As a result, the uid encounters a constant strength at all points, ows linearly through the block, and ensures ecient dehydration and minimum charge loss. e block is chemically inert, not deliquescent, does not react with refrigerating uids, and is capable of blocking oil by-products dragged into the circuit. Impurities accumulate in the ring between the metal shell and the block; this prevents lter...

Comparing this calculated reference ow capacity with the values shown on table 3, the result involves the selection of lter 4305/3S with a ow capacity of 17,8 kW., at a pressure drop of 0,14 bar. Comparing the absorption capacity required with the values shown in table 3, drier mod.4341 should be selected, with a water absorption capacity of 40,5 g at 50 °C. If the dehydrating capacity of products is expressed in water drops, it must be remembered that: FILTER SELECTION BASED ON WATER CAPACITY System data: Refrigerant: R407C Liquid temperature: + 50 [°C] Evaporating temperature: - 10 [°C}...
