Product catalog summary
Overview: The document is a technical datasheet for the Diadef deposit separator with air separation function, produced by Comparato Nello SRL, a UNI EN ISO 9001:2015 certified company. The device is designed to reduce impurities in fluid systems by promoting sedimentation and air bubble ejection.
Use and Features: The Diadef separator operates by creating a low turbulence zone, allowing gravity to settle impurities. A grid inside the separator further reduces particle speed, aiding sedimentation. A sump collects sediments, which can be drained periodically. The design minimizes pressure drops compared to other filters.
Peculiarities: The separator can handle a maximum fluid temperature of 90°C and a pressure of 5 bar. It is made from carbon steel EN10255 and coated with a red water-based primer.
Technical Features: The device includes flame-retardant polyurethane insulation with a silver coating. It is available in threaded and flanged versions, with various sizes and flow rates detailed in the document.
Fluid-Dynamic Features: The document provides flow coefficients (Kv) and flow rates (Q) for different sizes, with pressure drop calculations based on these values.
Versions and Connections: The datasheet lists codes for different connection types, including threaded male and flanged connections, with corresponding insulation codes.
Non-Standard Options: Custom iron and stainless steel separators are available upon request, tailored to client specifications.
Example Specification: An example specification for a thermal power station application is provided, detailing connection types, valve sleeves, and material specifications.
Contact Information: Comparato Nello SRL is located in Cairo Montenotte, Italy, with contact details and a website for further information.

DIADEF deposit separators-1

DEPOSIT SEPARATOR WITH AIR SEPARATION FUNCTION USE AND FEATURES The operating principle of the Diadef deposit separator provides for a low turbulence zone where the fluid flow has a very low speed compared to the pipes: in this way the dragging effect on single particles of impurities is significantly reduced, while the action of gravity prevails, helping their settlement on the bottom of the deposit separator. In order to promote this condition, inside the deposit, crosswise to the flow direction, there is a grid (see drawing and table at the bottom of the page): dirt particles hit the grid, further lowering their speed and, therefore, they sediment more easily. In the lower part of Diadef there is a sump for sediments that, once settled, can not re-enter circulation because of the above-mentioned low speed: then, the periodic opening of a drain cock allows the draining of the sump. The connection position has been designed in order to ease the above mentioned functions. PECULIARITY The low speeds inside the Diadef deposit separator allow the dirt collection, the ejection of air bubbles and, moreover, they give another important feature to the device: low pressure drops, in general and in particular, in comparison with other comparable filters.
