Bacharach’s all new Pur-Chek™ Pro is the ultimate HVAC/R refrigerant analyzer that enables fast and accurate testing of the widest range of refrigerant analysis ever offered in a portable instrument. Pur-Chek™ Pro indentifies more than a dozen HVAC/R refrigerants and provides a complete component breakdown of refrigerant blend ratios that can be printed out with the built-in printer.

Designed for Consolidators and Reclaimers.
With the global mandate to significantly reduce the supply of R22 availability by replacing it with many new refrigerants, understanding which refrigerant you are working with becomes critical business information. Non-dispersive infrared (NDIR) technology determines the weight concentrations of refrigerants and provides a component breakdown of the blend ratios and air. ’Blend-Chek Pro’ analytical software quickly and accurately identifies and analyzes common 400 Series refrigerants including R404A, R407C and R410A. Pur-Chek™ Pro automatically determines the purity of refrigerants reducing the potential for human error.

With this diagnostic analyzer, contractors can be sure of the type of refrigerant they are recovering. Refrigerant reclaimers use Pur-Chek™ Pro to check returned refrigerant before it can contaminate their bulk reclaim supply. Pur-Chek™ Pro provides the reclaimer with a quick means of screening a wide variety of refrigerants by both type and quality. It dramatically reduces the need for costly gas chromatograph (GC) testing of small tanks, saving time and money while providing critical analysis of HVAC refrigerants.

Applications.

Reclamation.

Refrigerant reclaimers have unique requirements and the Pur-Chek Pro has been engineered with these needs in mind. The reclamation process is integrally dependent upon the initial purity of the refrigerant components within the cylinders. Contaminants such as oil, moisture acid and particulate can be easily removed however it is far more difficult and costly to separate refrigerants. Because of this, the returned cylinders must be tested for refrigerant content and purity before they are processed and performing a gas chromatograph test on every cylinder is far too time consuming and costly. The Pur-Chek Pro provides a cost effective alternative allowing the reclaimer to quickly and easily check the type and quality of the refrigerant in the cylinder.

Consolidation.
Many Wolesalers/ Distributors have instituted programs to take back recovered refrigerant from their customers. The origins of this refrigerant are often unknown to the Wholesalers/ Distributors and the cost to dispose of a 50lb. tank of mixed refrigerant could exceed $300.00. In the past, many Wholesalers/ Distributors would send the refrigerant to the reclaimer to have it analyzed and then be forced to back charge the contractor who brought them the refrigerant if it was mixed. Clearly this was not an easy task leading to mistrust and poor customer relations. The Pur-Chek Pro allows the Wholesaler/ Distributor to test the refrigerant on the spot before the contractor leaves the facility and inform them if an additional charge or credit is anticipated.

Large Contractors.

Contractors working on a variety of HVAC, refrigeration, chiller and industrial applications will have to deal with many refrigerants. Knowing the type and purity of the refrigerant in a system is critical to both diagnosing system problems and preventing mixing of large quantities of refrigerant resulting in high disposal costs.
	The Pur-Chek Pro is an advanced refrigerant analyzer for use in refrigerant reclamation, consolidation and HVAC/R service. Features of the Pur-Chek Pro instrument include: Widest range of refrigerants Installed printer for record-keeping Internal battery option Remote software updates

Frequently Asked Questions.

1. What is a refrigerant identifier? A refrigerant analyzer is an instrument designed to differentiate between various types of refrigerants and analyze their component content.
2. How do refrigerant analyzers work? Each type of refrigerant has a unique infrared signature. Analyzers take a small sample of the refrigerant and use infrared technology to interpret these signatures and analyze the refrigerant. Certain refrigerants can be analyzed in depth including determining the component breakdown. Other refrigerants can only be identified.
3. What refrigerants can the Pur-Chek Pro analyze? The instrument can analyze R134A, R22, Hydrocarbons, R404A, R407C and R410A.
4. What refrigerants can the Pur-Chek Pro Identify? The instrument can identify many other refrigerants including R408, R409, R417, R422 and R427.
5. How are the test results displayed? Test results are displayed on the LCD display including the refrigerant type and percentage. The total of the percentages will be 100%. Eg. R22 95%, R134A 5%.
6. What happens if I test a refrigerant that is not on the list of refrigerants this unit can test? If the refrigerant tested is not measured by the instrument, a result of “Unknown Refrigerant” will be displayed.
7. Does the Pur-Chek Pro require calibration? Yes, calibration is automatic and done prior to each test. An annual factory recalibration is recommended.
8. How many filters does the unit have? The Pur-Chek Pro has two filters. One metal filter at the coupler end of the hose and a white filter on the unit.
9. What does the metal filter near the coupler do? The metal filter has two functions. It reduces pressure and slows the migration of oil and liquid refrigerant. For sampling liquid, this filter may require frequent replacement.
10. What does the white filter on the top of my unit do and do I have to replace it? The filter on the top of the unit prevents small amounts of oil and liquid from getting into the unit. If red spots appear on the filter, it should be changed.
11. How do I know when either filter needs to be replaced? If oil or liquid appears in the clear hose the metal filter should be replaced. If pink or red spots appear on the white filter it should be replaced.
12. Can the filters be cleaned? No, the filters cannot be cleaned. They must be replaced with new unused filters.
13. What different powering options are there? This unit can be powered in two ways: The default 90 – 240 VAC power adapter or an optional internal battery.
14. How many tests can be run before the optional internal battery must be recharged? The Pur-Chek Pro can run approximately 30 tests on a freshly charged battery.
15. Can I power my unit from my battery charger? No, the battery charger can only charge the internal battery.
16. Can it test liquid refrigerant? Yes, a liquid testing assembly is supplied with the unit and must be used if testing liquid.
17. Are liquid tests more accurate? Generally, the results are the same for testing liquid or vapor. Gas Chromatographs use liquid samples to get the best representation of the sample contents.
18. What is the maximum sample pressure? The maximum pressure rating is 300 Psig.
19. What is the minimum pressure required for operation? The minimum pressure required for accurate readings is 20 Psig.
