Expansion Engine

Delhi Cryogenics Products Pvt. Ltd. is a medium scale industry setup by a team of experienced, highly dedicated & skilled engineers working in the designing, manufacturing and commissioning of oxygen-nitrogen plants & acetylene plants for more than 20 years. As a leading and reputed company, it is engaged in manufacturing and Supplying Oxygen plants, Nitrogen plants and Acetylene plants in India. Incorporated in 1987 at New Delhi, India, the company is equipped with latest and state of the art technologies. We supply a broad range of oxygenmedical and industrial gas plants and processing equipment for both industrial and medical customers all over the world.
We offer technically advanced oxygen plants, liquid oxygen nitrogen plants, oxygen gas plant, cryogenic liquid oxygen plant, nitrogen generators, liquid oxygen generators, acetylene gas plants and more. Designed in compliance with international quality standards, these plants also help in the filling of gas pressure in cylinders.
We manufacture cost-effective, safe and reliable oxygen generating systems for high quality industrial and medical use. Currently our oxygen plants are being exported to many countries worldwide, serving markets for bottling cylinders, industrial gas cutting of steel, production of steel glass Petrochemical industry, Fabrication, Medical use in Hospitals, Oil & gas Industry, and Animal Husbandry.
Our Process is based on the latest design and technology of Liquefaction of AIR where the basic principle of deep refrigeration and cooling is used to liquefy the atmospheric air specially suitable to produce liquid oxygen-nitrogen and filling high pressure oxygen Nitrogen of high purity cylinders & bottles and safe to operate for production of medical and industrial oxygen because the pure oxygen can be filled directly into cylinders without coming into contact with the air or moisture


Expansion Engine

The Expansion Engine is a vertical single acting reciprocating type engine.The Electric Motor is used initially to start the machine. Thereafter the engine is moved by the air pressure itself and during which time, the engine motor retains the speed by acting as a brake. Since work is done by air in rotating the Flywheel, it loses its heat content (enthalpy). Thus the air gets cooled. This cooling is more than that of an expansion in an expansion valve. Our High Pressure Expansion Engine is used for liquid Plants.

The Expansion Engine can be considered as three major units:

1. The drive unit.
2. The Cylinder Unit for air expansion
3. The Hydraulic Systems for operating the Valves

We are a manufacturer and supplier of a large number of Expansion Engines of numerous types such as single, vertical and reciprocating. When manufacturing the plants, we keep in mind the requirements of our clients. Our products are come in three major units such as cylinders unit, hydraulic systems and drive unit. Apart from high quality products at discount rates, we ensure longevity, durability and ease of use of our products.
