SCOPE :-

HOLYSCIENTIFIC is one of the leading science equipment manufacturer & exporter our equipments are widely used in many industries like laboratory sterilization, clean room, microbiology, pathology, bio technology, pharmaceuticals, seed & soil testing, metallurgical, food processing and many more. Cloud & pour point apparatus is widely used in oil and petroleum industries.

Usages :-

Cloud point and pour point are indicators of the lowest temperature of utility for petroleum products. The sample is periodically examined while it is being cooled in the cloud and pour point apparatus. When oil cooled slowly, the temperature at which it appears hazy or cloudy is known as cloud point. The temperature at which oil stops flowing even after tilting the glass containing the oil under test to a horizontal position for 5 seconds is known as pour point.

cloud pour points determined by pour point apparatus. the lubricating oil sample is filled (to a height of 2’’ to 2) in a flat bottom glass tube of 30 mm in diameter and 120mm in height. The tube is covered tightly by cork stopper. The glass tube is enclosed by air jacket the whole assembly is dipped in a freezing mixture. The freezing mixture depends on the working temperature range of the apparatus.

Features

  • RASAYAN cloud & pour point apparatus confirms ASTM D-97, ASTM-D5853 and related specs.
  • Compaq design. Table top and floor both models available.
  • CFC free Vapor compressor based refrigeration system with preset cold bath
  • Individual digital temperature controller for each chamber
  • Temperature : 0 °C,-17 °C, -34 °C,-51 °C and -65 °C
  • Power Supply : 230 volts, single phase, 50 Hz

MODE OF HEATING :-

RASAYAN cloud & pour is made according to specification laid by IP by 15 & ASTM D 97. The Pour Point is lowest temperature at which the oil will just fail to flow. The apparatus consists main cooling bath made out of S.S. Sheet and stand Unit with drain Plug and cover has provision for fitting thermometer and a filling adventure for adding freezing mixture. A Glass Jar for containing Oils, Jackets, Disc and gasket as specified are also provided. Bench-model and floor-model test units with multiple four-jacket mechanically refrigerated baths, each factory preset at a different temperature for convenient cloud and pour point testing. Bench model has three baths, set at +30, 0, and –30°C floor model has four baths, set at +30, 0, –30 and –60°C. Each bath has a S.S made top plate with ports for thermometer and four copper test jackets. Synthetic sponge covers over each top plate and gasket hoods over each bath prevent excessive ice accumulation around the test jackets. Cascade hermetic refrigeration system provides reliable long term service. Bath interior and cabinet is constructed entirely of stainless steel. Cloud & Pour Point Appratus, Floor model rides on swivel castors. Supplied with test jackets, gaskets, disks, and thermometer holders for test jars and cooling baths.
