Pour Point, Cloud Point, Freeze Point, and Cold Filter Plugging Point (CFPP) of Petroleum Products – ASTM D97, D2500, D5853, D6371, D6422 | IP 15, IP 16, IP 219, IP 309, IP 441 | ISO 3015, ISO 3016 | DIN 51597| EN 116, EN 23015 | NF T 60-105 | FTM 791 201 | JIS K 2269
Model DR4 series of chillers for cooling the automated analyzers uses the Lawler developed concept of direct refrigeration. The test cup (metal jacket) for cloud point, pour point, or CFPP is directly cooled by the refrigerant, thus replacing the middle step of first cooling the flammable alcohol and then pumping the cold alcohol to the test jacket. Offers the additional advantage of rapid cool down to test temperature within minutes versus hours with bulky floor model cryostat models. The automated analyzer is mounted on the same cabinet as the refrigeration system, thus saving valuable laboratory space. DR4 series coolers are available in 1 or 2 test positions with lowest temperature of either -34° or -70°C.
Model OL series are designed to work with an external alcohol chiller, either your own or supplied by Lawler. OL series units are available in 1, 2, 3, or 4 position units. Lawler offers two recirculating chiller models (MRCC-80 and MRCC-5) for use in conjunction with the OL analyzer.
Model MRCC-80 is a high capacity cryostat able to cool up to three Model OL series analyzer positions.
Its lowest operating temperature is -70°C.
Model MRCC-5 is a very high capacity cryostat able to cool up to six Model OL series analyzer positions.
Its lowest operating temperature is -70°C. This model has a 5 year guarantee against compressor failure.
A wide range of models is available with working temperature ranges from +48° to -69°C. Each multi-bath unit conforms to ASTM D97 Pour Point and ASTM D2500 Cloud Point test methods and related methods. Each stainless steel liquid bath has its own digital indicating PID temperature controller with 0.1°C resolution, providing temperature stability of ±1.5°C. The baths of select models are agitated for improved temperature stabily (±0.5°C) and uniformity and are, therefore, suitable for ASTM D6371 (or IP309) cold filter plugging point test with the addition of the CFPP kit. Each bath comes equipped with 4 metal test jackets, 4 cork rings, 4 O-rings, and 4 cork stoppers for the thermometer (test tube is available separately). All units are mechanically refrigerated using ozone friendly non-CFC and non-HCFC refrigerants.
Model 334 is the most popular and versatile 3 bath bench model is the “work horse” of the industry. The baths are factory preset at 0°, -18°, and -33°C. Each bath has 4 test sample capacity. The approximate overall dimensions are 25 x 19 x 26 inches high (62 x 48 x 65 cm).
Model 644 is also a popular caster mounted, floor model with 4 baths factory preset at 0°, -18°, -33°, and -51°C. Each bath is mechanically agitated for improved bath temperature uniformity and control. Each bath has 4 test sample capacity. Approximate overall dimensions are 37 x 31 x 43 inches high (94 x 78 x 110 cm.)
Model 654 is a caster mounted floor model with 5 baths factory preset at 0°, -18°, -33°, -51°, -69°C. Each bath is mechanically agitated for temperature stability of ±0.5°C.
Model 549 is a single liquid bath apparatus with 4 sample test capacity, adjustable from 0° to -69°C. Its temperature stability is ±1.5°C. It is an economical choice for those laboratories with samples with extra low temperature pour point samples.
Model DR-2L with two test positions is a portable, unique cloud and pour point bath, not using any liquid as the cooling medium. It has the ability to very rapidly (less than 2 minutes) change the metal cup temperature to the next lower temperature. This allows one bath to perform the pour and cloud point as well as CFPP tests without the need to move the test tube to the next lowest bath temperature. Each cup has its own digital temperature controller and their temperature may be set independently. Lowest bath temperature is -69°C.
Model DR-1H/L is similar to Model DR-2L and is an economical, compact single test position bath with lowest bath temperature of -33°C. It is an ideal bath for mobile fuel testing laboratories. Overall dimensions are 22 x 18 x 33 inches high (55 x 45 x 83 cm).
The DR5 is a cold properties analyzer. A unique interchangeable cartridge system allows cloud, pour, and CFPP on the same machine. The DR5 is single position. There are three types of cartridges: cloud, pour, and CFPP. Each DR5 comes with a single cartridge. Upon ordering, please specify which cartridge type to include. Additional cartridges can be bought as accessories. The DR5’s state-of-the-art cooling system allows temperatures from -120°C to 60°C. It cools at a rate of 1° C in 5 seconds or less. It maintains temperature of +- 1°C.
- Low consumption.
- No calibration required.
- Cloud, pour, and CFPP on a single machine.
- Only 11 inches wide.
- High resolution, tablet-style touchscreen.
- Fully contained, maintenance-free refrigeration system.
- View current test in real-time from a PC, tablet, or smartphone via wifi or ethernet.
- Easily export test data to LIMS, flash drive, or web browser.
- Print tests from machine.
In addition to standard tests, the machine can be set to maintain a certain temperature, which is convenient for various lab activities. Note: “Plunge Style” indicates a large initial drop in temperature and then maintaining that temperature. This allows for faster test results. It gives an approximation of the test result but is no substitute for ASTM tests. This was provide via customer request.
