Evaporator and Vaporizer Systems
Evaporators play a vital role in converting cryogenic liquids such as LCO2, LOX, LIN, LAR, and LNG stored or transported in cryogenic tanks back to gas phase. Furthermore, these systems use ambient temperature to supply the energy required for liquid evaporation. Moreover, we convert the liquid to gas ready for consumption without requiring an additional energy source. Consequently, we reduce operational costs significantly on every installation.
High-Efficiency Heat Transfer and Design Features
We equip the evaporators we manufacture with custom engineering solutions to achieve phase transition in the most efficient way. Furthermore, we deliver the following technologies as standard on every unit:
Aluminium Alloy Technology
We manufacture finned tubes from special extruded aluminium alloy and connect them in series and parallel configurations. Furthermore, this structure delivers high heat transfer efficiency. Moreover, the aluminium alloy provides full resistance against cryogenic temperatures. Consequently, we offer long service life with low maintenance costs.
Maximum Surface Interaction
We maximise surface interaction with the environment through our finned tube design. Furthermore, this maximises heat transfer efficiency on every unit. Moreover, we meet the gas capacity your operations require in the most effective way. Consequently, we guarantee uninterrupted gas flow at all times.
Durable Structure
We select materials that deliver full resistance against cryogenic temperatures and high pressures. Furthermore, this selection guarantees long-term reliable operation. Moreover, we design for the full pressure range from 5 Bar to 450 Bar. Consequently, we provide a solution for every industrial requirement.
Environmental Factors Affecting Performance and Engineering
We calculate all variables that directly affect evaporator performance with precision. Furthermore, we manufacture across a wide range from low to high pressure. Moreover, we consider the following critical factors throughout the design process:
- Furthermore, we calculate material flow rate and operational duration.
- Moreover, we assess the altitude above sea level and atmospheric temperature of the installation site.
- In addition, we analyse relative humidity and icing/frosting cycle duration.
- Consequently, we also include wind speed and solar radiation effect in our engineering calculations.
Industrial Application Areas
We apply Harsan evaporators with confidence in every industry requiring controlled cryogenic liquid vaporisation. Furthermore, we deliver solutions to the following sectors:
- Furthermore, we provide continuous gas flow for cutting and welding processes in metalworking and heavy industrial facilities.
- Moreover, we supply medical gas systems for hospital infrastructure in healthcare and medical facilities.
- In addition, we produce reliable vaporisation solutions for food processing lines and precision laboratory work.
- Consequently, we serve all production facilities where continuous and controlled gas supply is of critical importance.

Evaporator and Vaporizer Systems — Frequently Asked Questions
What is a cryogenic evaporator (atmospheric vaporizer) and how does the system work?
Evaporators are heat exchanger systems that convert cryogenic liquids such as LCO2, LOX, LIN, LAR, and LNG back to gas phase. Furthermore, atmospheric vaporizers carry out this process without requiring an additional energy source. Moreover, they use ambient temperature to supply the energy required for liquid evaporation. Consequently, we deliver gas ready for consumption at your facility and reduce operational costs significantly.
How do you achieve high heat transfer efficiency in atmospheric vaporizer systems?
We use finned tube technology manufactured from special extruded aluminium alloy to achieve phase transition in the most efficient way. Furthermore, we connect these aluminium profiles in series and parallel configurations. Moreover, this structure maximises surface interaction with the environment. Consequently, we deliver the continuous gas flow your operations require without interruption.
What environmental factors affect the performance of cryogenic evaporators?
The gas conversion capacity of atmospheric vaporizers depends directly on the ambient conditions of the installation site. Furthermore, the altitude above sea level, atmospheric temperature, and relative humidity directly affect performance. Moreover, wind speed, solar radiation, and icing/frosting cycle duration are also critical factors. Consequently, Harsan engineers calculate all these variables with precision during the project phase and deliver the most suitable design for your facility.
What are the operating pressure and flow rate options for industrial evaporators?
We manufacture in compliance with EN 13445 and ASME SEC VIII 1 standards across a design pressure range of 5 Bar to 450 Bar. Furthermore, we customise flow capacity from 5 Nm³/h up to 5000 Nm³/h and beyond according to your operational demands. Moreover, the design temperature range is –196°C to +50°C. Consequently, we deliver a precisely scaled solution for every industrial facility.
