Cleaning of cooling coils
Cooling coil cleaning system in the food industry
We incorporate 6 spinners to a frame to guarantee a homogeneous sanitization and disinfection of all parts of the conveyor in an agile way.
Original situation:
Challenges posed by the client:
Need to clean four cooling coils during weekly shutdown (8 hours)
During this time, production is completely stopped and the plant is cleaned by a team of external specialists.
Resources used:
- High-pressure washers (x2)
- Water consumption – 1,200L/hour, 6,000L/week
- Chemical products, particularly caustic soda, a highly contaminating substance.
- Need to hire 4 operators during the cleaning shift (annual cost of c. €30,000).
Issues:
- Excessive water consumption.
- Mediocre results with reduced pathogen elimination
- Need to use chemicals.
Proposed solution:
Automation consisting of 6 spinners on a frame
Proposed solution:
The solution consists of a 120 kW fixed steam generator with two steam pipes, one for each application point.
The operation is carried out by positioning a set of 6 spinners on a frame that would be interchangeable between the two thanks to the installation of anchors (plug and play) that would facilitate the positioning of the frame at the point of application.
Both systems act automatically on the belts without the use of MOD, drastically reducing water consumption and simplifying the process.
Technology used:
- 6 spinners
- Frame, connections and anchorages at the points of application
- Steam generator NGV60120
Benefits
Return on investment in less than 18 months
Higher sanitization levels due to the effectiveness of saturated steam application at 180°C with spinners
80% reduction in water consumption, including the elimination of any chemical products.
Reduced labor requirements. Only two operators are required on a one-time basis (10 minutes) to change the location of the frame.

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.
