HeldonIntroduction New refrigerants and synthetic oils (such as POE/PAG) demand a

more precise operating environment than ever before. Excessive

moisture and contamination levels can quickly lead to a loss

of refrigeration capacity, system efficiency or even breakdown.

The Solution?

Trust in time-tested Heldon Filter Driers/Drier Cores to offer

reliable, long lasting protection, for both food service and

air conditioning applications, whether new installation, field

replacement or retrofit.

The First Line of System ProtectionThe Filter Drier/Drier Core in a refrigeration or air conditioning

system is often referred to as the system protector, because it

removes harmful elements from the circulating refrigerants and

lubricants before serious damage results.

The Filter Driers/Drier Cores Function

The primary contaminants which Filter Driers/Drier Cores

are expected to remove are:

1. Moisture.

2. Acids.

3. Solid contaminants such as metal filings, flux, dirt,

oxides and wax.

4. Sludges and Varnish.

1. MoistureMoisture or water can come from many sources:

• Improper dehydration of new equipment.

• Improper field assembly or poor service procedures.

• Refrigerant leaks.

• Wet refrigerant.

• Wet oil, Poly-ol Ester (POE) which is much more “moisture loving”

(hygroscopic) than mineral oils.

*Note that if the moisture content of the POE oil is greater than

75 PPM (parts per million), the POE reverts back to its original

chemical – an alcohol and an organic acid. Alcohol reduces

the Filter Drier's effectiveness with water and acid attacks the

refrigeration system's internals.

A leading international compressor manufacturer’s experience

with Poly-ol Ester Oil is presented in Fig. 1.

The seriousness of POE’s hygroscopic nature is depicted as the

compressor with its oil, moves its way from manufacture, to rack

fabrication, to field installation and finally comissioning.

For the most cost effective method of removing the harmful effects

of moisture, simply choose a Heldon Filter Drier/Drier Core.

TECHNICAL INFORMATION - FILTER DRIERS/DRIER CORES

HeldonFigure 1.

2. AcidsAcids are formed by a combination of refrigerants being heated

to elevated temperatures and the presence of high moisture

content in the system. This Hydrolysis forms both Hydrochloric

and Hydrofluoric (inorganic) acids. Organic acids are also created

from the lubricants breakdown in the presence of moisture.

Since acids attack and corrode the metals in a refrigeration

system, it is crucial that they be removed as quickly as possible

to minimise damage.

It is crucial to beware of the harmful effects of high discharge or

condensing temperatures on refrigeration systems, as they act

as the major catalyst in the production of acids. It is good trade

practice to replace the Filter Drier or Core whenever a system has

operated for extended periods under high operating temperatures.

Heldon Filter Driers/Cores have a critical mission to remove this

acid, prolonging the life of compressors and refrigerants.

Case Study

A recent Air Conditioning and Refrigeration Institute (ARI) study

showed that even weak acid circulating in a refrigeration

system could reduce a compressor’s life from one million hours

to approximately 1,000 hours.

3. Solid ContaminantsThese include dirt, copper oxide scale, sludges, flux, metallic

particles etc. Such contaminates can be introduced during

manufacture, field assembly or service. They can damage

compressor cylinder walls, bearings and cause blockages of

capillary tubes or TX Valve strainers. These contaminants create

the conditions necessary for the decomposition of the refrigerant/

lubricant mixture at high temperatures.

The effective removal of contaminants is difficult due to the wide

range of particle sizes that can be encountered in a system.

A refrigeration system demands:

• Thorough low micron filtration to capture these particles.

• Guaranteed uniform porosity through the entire Filter Drier

Core.

• A core shaped to give maximum surface area with negligible

pressure drop.

• Improved filtration, long lasting results.

Heldon Filter Driers/Cores offer thorough filtration with less

chance of total core blockage.

Heldon4. Sludges and VarnishEven the cleanest system when subjected to unusually high discharge

temperatures will suffer from lubricant breakdown. Sludge, varnish

and carbon deposits are some of the by-products of this occurrence.

A refrigeration system can feature certain catalytic metals (iron

& copper) that can further contribute to the refrigerant/lubricant

mixture’s breakdown.

What is a Desiccant?Desiccant is the material used to filter and dry the refrigerant and oil.

The four most commonly used desiccants are:

• 3A Molecular Sieve (MS) - most effective against moisture.

• Activated Alumina (AL) - most effective against acid.

• Activated Carbon (AC) - most affective against sludges and varnish

• Silica Gel

Total Filtration Management SolutionsHeldon’s range of Filter Driers /Drier Cores are manufactured from

the desiccants 3A Molecular Sieve, Activated Alumina and Activated

Carbon. The most suitable desiccant is chosen for the Filter Drier's

intended application and its location within the refrigeration system.

Heldon’s vast experience has resulted in the creation of proprietary

mixtures to target the removal of system contaminants before

they can do damage and cause breakdowns to the refrigeration

system. Designed in conjunction with the Suction Filter Element,

Heldon delivers total filtration management solutions for the benefit

of customers.

• 3A Molecular Sieve (MS)

Used for maximum moisture removal, the 3A Molecular Sieve

traps and removes water molecules from the circulating

refrigerant and oil. Tested in accord with ARI 710-86, when

installed in the Liquid Line these Filter Driers provide the

drying capacity necessary to keep the moisture content of

the circulating fluids below 75 parts per million (ppm). This

therefore avoids the creation of acids in POE oils.

Heldon’s 3A Molecular Sieve Filter Driers/Drier Cores are

suitable for the traditional refrigerants (including R717) as well

as the modern refrigerants including high pressure R410A

and CO2. 3A MS Filter Driers/Drier Cores deliver the most cost

effective means of removing the harmful effects of moisture

from the refrigeration system.

• 3A MS and Activated Alumina (AL) mixtures

For high performance moisture, acid and contaminant

removal, Heldon provides its customers with Filter Drier Cores

that contain a mixture of both 3A MS and Activated Alumina.

The Activated Alumina chemically attracts acids that may be

present in the refrigeration system, locking them away so

as to prolong the life of compressors, refrigerants, and oils.

Note that, high percentage mixes of AL are not recommended

for long term use with POE oils, as they can strip the

compressor manufacturer's oil additives from the systems

lubricant.

• 3A MS, AL and Activated Carbon (AC) mixtures

Best suited for clean up after burnout and for severely

contaminated systems plagued with moisture, acids, sludge/

varnish and other contaminant issues. Working in conjunction

with the other desiccants present in this type of Filter Drier, the

Activated Carbon cleans the operating system of the deposits

that contribute to the breakdown of refrigerant and lubricants.

When fitted, these Filter Driers/Drier Cores provide the best insurance

policy available for any compressor replaced in the field.

• Suction Core – 100% Molecular Sieve

Targets moisture & particulate removal from the suction line

before these contaminants can reach the compressor. Ideal

for commissioning purposes, these replaceable Cores feature

a unique design that delivers both low pressure drop, in

conjunction with high refrigerant flow rates.

Compressor manufacturers know that motor burnouts can be

caused by system contaminants returning down the suction

line. Foreign particles including copper oxides, metal and

copper pieces enter the compressor and become imbedded

in the motor windings themselves. As the compressor starts

and stops, these windings flex and move. The particles present

scrape the insulation of the motor windings leading to motor

burnout, system downtime and possible stock losses.

To extend the life span of the compressor, adequate filtration

is required before the suction service valve.

Specially designed for such an application, the Suction Filter

Element removes returning contaminants down to 10 microns

(Filter Beta rating = 10: ISO 4548-12). Its fluted design keeps

the collected debris safely imbedded in the filter whilst its large

surface area keeps pressure drop to a minimum.

Heldon Suction Filter Element provides the compressor with

the particulate protection it needs to prevent breakdowns

caused by a contaminated system.

Note that good trade practice dictates that the Maximum

recommended pressure drop in the Suction Line Filter for

commercial refrigeration (R134a) is 10.3 kPa.

Heldon

IntroductionHeldon Burnout Filter Driers offer a high level of contaminant

removal from refrigeration and air-conditioning systems following

a compressor motor burnout. Designed to remove moisture, acids

and solid particles that can lead to the premature failure of the

replacement compressor.

Employing a solid core design, Heldon Burnout Filter Driers deliver

minimal pressure drop via total core utilisation. This results in

quicker uptake of inorganic acids and other contaminants. The

solid core itself is formed through a binding process that maximizes

surface area and protects the core from acid decomposition.

Available in both standard and short lay-in lengths these models

feature inlet and outlet access Schrader ports for the monitoring of

pressure drop. For smaller suction pressure drop critical systems,

the 3026 series is supplied with a replacement jumper tube.

Note that it is good practice to remove suction burnout driers

after performing a successful acid test, in order to prevent loss

of system performance and the risk of catalytic hydrolysis in POE

oil systems.

Burnout Filter Drier

• Designed for use after motor burnout or mechanical failure; for clean up of the most contaminated systems.

• Activated Alumina and Carbon removes acids and waxes.

• Stainless steel mesh and a post core non-woven fine Polyester Filter provide additional filtering for the best in system protection.

• Suitable for use in either the liquid or suction lines. Best practice is to install Burnout Filter Driers in the suction line to

protect the replacement compressor.

• With POE and PAG oils, burnout driers should be removed as soon as all contaminants are absorbed from the system. This will

reduce the risk of catalytic hydrolysis and the formation of new acids.

• Safe Working Pressure 4,200 kPa (610 psi).

• Fitted with dual access ports to measure pressure drop.

Heldon

IntroductionHeldon offer a complete range of 48 cu. in Drier Cores to suit many

brands of Replaceable Core Drier Shells. Heldon Drier Cores

remove system contaminates and maximise the refrigeration

systems performance.

Together with the Suction Filter Element, Heldon delivers a total

filtration management system for its customers.

Ultra-Dry®: 100% Molecular Sieve.

Employing a 3A Molecular Sieve to trap and remove water

molecules, these cores deliver maximum moisture removal.

Suitable for traditional and modern refrigerants using mineral or

synthetic oils. This includes R717 and the HP refrigerants R410A

and CO2. Use these cores to safely remove moisture before acids

can be formed.

Standard: 80% Molecular Sieve & 20% Activated Alumina.

A blend of Molecular Sieve and Activated Alumina for high

performance moisture and contaminant removal. The Activated

Alumina chemically attracts acids that may be present in the

system. Thorough low micron filtration effectively captures

particles before they can do damage.

Burn-out: 48% Activated Alumina, 45% Molecular Sieves & 5%

Activated Carbon.

For clean up after burn-outs and for highly contaminated systems

with moisture, acid, sludge and particulate issues. The Activated

Carbon cleans the system of deposits that contribute to the

breakdown of refrigerant and oils, actively prevents contaminants

from causing premature failure of the replacement compressor.

Suction Core - 100% Molecular Sieve.

Targets moisture and particulate removal from the suction line

before it can reach the compressor. Ideal for commissioning

purposes, its unique design delivers low pressure drop with high

flow rates. Uniform porosity throughout the entire filter drier core

guarantees particulate filtration & retention.

Suction Filter Element - Fluted Filter Type.

Foreign particles destroy compressor motor winding insulation

and cause burnouts. Employing a fluted design for maximum filter

surface area, particulates down to 10 Microns (Filter Beta Rating

= 10: in accordance with ISO 4548-12) are safely removed from

the system. The Suction Filter delivers maximum compressor

protection with the lowest possible pressure drop. By installing a

Heldon Suction Filter Element you are providing the compressor

with the particulate protection it needs to prevent breakdowns

caused by a contaminated system.

Heldon

Introduction Heldon offers both the "Y" Type and In-line Strainer that allows for cleaning

of the strainer element without the need to replace the whole strainer. These

are suitable for refrigerants and liquids offering protection to compressors,

pumps, meters, valves and similar mechanical equipment.

Installation of a strainer before any mechanical equipment will ensure

trouble free service and avoid the costly shutdowns, repairs or replacement

often caused by the introduction of foreign particles into the system.

The “Y” Type;

The 80 mesh filter can be removed and cleaned with solvent and

compressed air. Y strainers can be installed in the horizontal or vertical

position as long as the filter mesh is accessible. The Strainer can be

removed for cleaning without the need to cut from the system.

In-line;

Heldon manufacture brass in-line strainers for capillary systems and

feature an accessible, cleanable 100 mesh strainer.
