FILLING IN LIN DEWAR'S/DURA LIQUID CYLINDERS
Oxyplants India Pvt. Ltd. offers a full line of Dura liquid cylinder. The Dura liquid cylinder is designed to transport, store and deliver oxygen, nitrogen, argon, as a cryogenic liquid or gas. Dura cylinders are vacuum and super insulated vertical type liquid cylinders with in-built vaporizer which allows storage of cryogenic gases like oxygen, argon, nitrogen, medical oxygen at a very low temperature ranging From -183deg c To -196 deg c. The Dura Liquid Cylinders are manufactured in India As a design standard it is used CODE DOT4L, EN 13458 and ASME standards. Dura Cylinders are low pressure liquid cylinders provide the longest holding time, lowest evaporation rate, highest gas-withdrawal rate and best life-cycle cost.
Dura Liquid cylinders Tanks are produced to store liquid. The inner tank is made our of Stainless Steel 304L(SA240 TP304) & design code DOT4L. While the outer one is made out of stainless steel 304L (AISI304) & design code CGA-341,Ed.2007 . The common application for this liquid cylinder is to provide gas at pressures around 300 psi (20.7 BAR). The Dura Liquid Cylinder will build and maintain pressure at the control regulator setting of 300 psi (20.7 BAR). If the pressure exceeds 300 psi (20.7 BAR) the control regulator will supply gas from the tank vapor pressure. A continuous gas flow can be automatically provided from these cylinders.

AMBIENT AIR VAPORIZER
Oxyplants India Pvt. Ltd. supplies Atmospheric vaporizers for Liquid Nitrogen, Liquid Oxygen, and Liquid Argon and of various capacities ranging from 20 to 1000 NM3/ Hr. Ambient Air Vaporizer utilize convection as the heat transfer mechanism. Ambient air vaporizers use the relative "heat" of the atmosphere to derive the energy necessary for the vaporization of the liquid cryogen. Ambient vaporizers represent the most cost effective equipment to vaporize or re-gasify liquid cryogens. The vaporizers comprise a number of individual multi-finned aluminum heat transfer extruded elements lined with a high pressure retaining stainless steel tube. Extrusions are connected in series. Liners are hydrostatically expanded (tension bonded) into the extrusion element to ensure 100% contact and efficient heat transfer.
Vaporizers are designed and manufactured in accordance with the ASME Section VIII Div 1 latest edition pressure vessel code and the UBC and applicable sections of ANSI A 58.1. Vaporizers may be manufactured in compliance with any global pressure specification, such as ASME; TüV; PED; and other international codes.
The performance of ambient air vaporizers is subject to many factors. These include flow rate, duty cycle, ambient temperature, relative humidity, freeze period, altitude, wind, solar radiation, operating pressure and proximity to adjacent structures. The effects of average solar and wind conditions are not included in quoted ratings. Performance is based on mean ambient conditions of 70°F (21°C) and 70% relative humidity. Special conditions may vary considerably for a particular application, thereby affecting performance.
