Steam system for shrink-wrapping machine
Project description
Steam solution for a packaging machinery manufacturer customer that needed to optimize the process of shrink wrapping with steam in their packaging lines.
Original situation:
Challenges posed by the client:
The customer is a packaging machinery manufacturer that was faced with the challenge of optimizing the steam shrink process on its packaging lines.
After the vacuum packaging process and hermetic sealing of the product, it was essential to apply steam to the bottom film of the package to complete the shrink wrapping. But there was an essential requirement related to the maximum steam pressure.
The project had to meet the following requirements:
- It could not exceed a maximum pressure of 1.2 bar: the process of applying steam to the bottom film of the package to complete shrink-wrapping had to be carried out in compliance with a very specific technical requirement, without exceeding a maximum pressure of 1.2 bar, a condition imposed by the design of the shrink-wrapping machine.
- A compact, efficient and safe solution: the challenge was to offer a compact, efficient and safe solution, capable of generating and supplying steam at the required pressure, meeting the customer’s quality and reliability standards.
Proposed solution:
Customized steam solution developed by Giconmes.
Proposed solution:
- Steam generator NGV-1715 (15 kW) manufactured in stainless steel AISI A-304: Giconmes proposed a complete and integrated solution, based on the installation of an electric boiler model NGV-1715 of 15 kW, specifically designed for environments where a high degree of hygiene and resistance is required. This boiler has all its components in contact with water made of AISI A-304 stainless steel, as well as its external fairing, which guarantees durability and ease of cleaning. It is equipped with a safety valve set at 7 bar / 170.5 ºC and a water level protection system, which stops the boiler automatically in case of water level failure, ensuring the safety of the installation.
- Condensate recovery tank model DRC00160: with a capacity of 160 liters, also entirely built in AISI A-304 stainless steel, this tank includes level regulator, solenoid valve and thermostat, allowing an efficient management of condensate return and contributing to the energy sustainability of the system.
- Pressure reduction system: designed to reduce the output steam pressure from the 4 bar generated by the boiler to the 1.2 bar required by the shrink-wrapper, ensuring full compatibility with the customer’s process.

FAQs
We understand that many questions may arise. Here are some of the most common ones.
There are no emissions beyond those produced during the electricity production process. Consequently, emissions can be neutral depending on the electricity mix. Electric steam boilers are the present and the future.
Absolutely. In fact, it is recommended to achieve maximum efficiency. There is no problem with remote control as long as it complies with current regulations.
A steam generator is a pressure vessel that, together with the piping network, is subject to regulatory control and complementary technical instructions, according to the regulations published in Royal Decree 809/2021, of September 21. Maintenance is divided into a part that can be easily fulfilled by the owner:
- Know and apply the manufacturer’s instructions regarding use, safety measures, and maintenance.
- Not to put the installation into service or prevent the operation of pressure equipment if the requirements of the Regulation are not met.
- Having at least the following documentation for the pressure equipment while they are installed: Declaration of conformity, manufacturer’s instructions (if applicable), and, if necessary, installation certificate, along with other supporting documentation (such as installation project, record of the last periodic inspection, certifications of equipment repairs or modifications, and any other documentation required by the relevant technical instruction complementary to this regulation). For detailed contents, refer to Annex IV of the regulation. Making this documentation available to the competent authority of the autonomous community and the companies responsible for maintenance, repair, or periodic inspections.
- Use the pressure equipment within its intended operating limits as specified by the manufacturer and take it out of service if it no longer meets the necessary safety requirements.
- Perform maintenance on the installations, pressure equipment, safety accessories, and control devices in accordance with the operating conditions and manufacturer’s instructions, and examine them at least once a year.
- Arranging for the necessary periodic inspections as required by Article 6 of the regulation.
- Having and maintaining an up-to-date record of pressure equipment categories I to IV, as defined in RD 709/2015, of July 24, or equipment similar to these categories according to Article 3.2 of the regulation, as well as their installations.
It is known that by applying heat to water, it transforms into steam at the boiling point and atmospheric pressure. From there, depending on the required saturation degree of steam for its proper application, we need to increase the pressure to obtain a higher temperature. To change the temperature and saturation degree of steam, we always need to modify the pressure.
It is a unit of pressure equivalent to 1 kg/cm2, 0.98 atmospheres, or 14.50 PSI.
