Pressure points

OMZ has been providing tank washing services to customers for almost 70 years. Tank Cleaning Magazine caught up with OMZ’s Moreno Romanini about the company’s growing success.
Can you tell our readers a bit about yourself and OMZ?
I am the operative director of OMZ, a company which is involved in industrial washing plants and highly automated washing systems that answer the needs of our customers. OMZ ranks among one of the leaders in its field, in my opinion, boasting the title of being one of the first companies in Europe to develop a broad range of rotary washing equipment subsequently used as a benchmark by competitors.
Can you outline what OMZ does in the high pressure tank washing business? Why is this work so important?
In the early 1980s, OMZ decided to focus its operations on the design and development of high-pressure washing systems able to guarantee the highest level cleaning of tankers (according to EFTCO directives), tank cars and the chassis of both road and rail vehicles. The technology and versatility of OMZ systems has ensured the diffusion of our products worldwide.
Can you give a brief overview of your tank washing processes? These systems, developed at the company’s own facilities in Santo Stefano Ticino on the outskirts of Milan, Italy, rely on proven technology such as rotary washing heads (ATEX certified) in production since the 1970s, driven by a special series of hot and cold water pump units.
The flow rate and pressure performance characteristics have been developed by OMZ technicians. These pump units are for high pressure operations between 50 and 800 bar with flow rates from 20 to 380 litres per minute. The systems can be completely customised because at OMZ, all client ideas and needs are carefully evaluated to satisfy every request.
To meet their different needs, the work can be completed efficiently and to the highest standards thanks to:
• More washing lines, which work simultaneously;
• The use of hot water, obtained through heat exchangers or through efficient generators;
• The feeding of the heat exchangers through high pressure pump systems that improve efficiency;
• The use of steam for effective tank cleaning;
• The addition of detergents, through high pressure dosing pumps;
• The use of cost-effective drying systems; Efficient systems for the sterilisation of tanks, which is carried out following the binding protocols of the food industry and according to EFTCO food hygiene directives;
• An automated management system, which has an unlimited number of washing programmes and helps with tank traceability processes.
How does your company stand out from its competitors?
What distinguishes OMZ from the rest of the market is the focus we place on our customers. Before each cleaning project is carried out, in-depth research and analysis of the customer’s needs and requirements are undertaken to guarantee top quality results. Furthermore, the relationship with our customers does not end at the culmination of this process, but continues through further assistance on dedicated WhatsApp channels and customised maintenance programmes.
Have there been any new developments within OMZ in the past 12 months? In recent months, new plants have been built that have seen us become present not just in Europe, but further afield. For example, one of our latest achievements was the completion of a tank washing plant in Santo Domingo in the Dominican Republic with two washing lines (one chemical and the other food) plus a line for external washing. Furthermore, a few months ago we embarked on a quality assurance path that we hope will lead us to obtain ISO 9000 certification.
What sustainability practices does OMZ employ?
OMZ is attentive to the issues surrounding sustainability. In the last two years, we have invested in photovoltaics, covering the roof of our offices with the latest electricity generating panels. As far as our systems are concerned, the thermal output of our boilers is above 90%, so they fall within the European parameters of gas injection. We also use frequency variators on all electric motors, making a significant saving in electricity consumption.
What are the biggest challenges facing your sector at the moment?
The challenge that every sector must face in this period is certainly to overcome the effects of COVID-19 as soon as possible, and things have certainly improved since last year. Fortunately, our company, being part of a primary supply chain, did not have to close and was able to continue its business. Indeed, we have invested in personnel and machinery to try to become stronger and more competitive than we have been in the past.
Are there any new developments or investments in the pipeline?
We are about to purchase new land adjacent to the workshop which will allow us to significantly improve logistics and allow us to dedicate a larger space to the containers used for transporting. OMZ wants to have a bigger presence not only in Europe, but also worldwide.
