Six professional cleaning technologies, equipment sales, rental, service and training — selected around the application, not forced onto it. Show us the surface, contamination and required result, and we'll help determine what is worth testing first.
Where do we start?
Help me choose
Two questions. A reasoned first recommendation. We'll show you what we would test first, the alternative we would compare it with, where each method reaches its limits — and when the honest next step is to test the real part.
The recommendation starts from our own machine datasheets and from the physics of the process. The final decision is made on your part, at a demonstration.
Proven in industry
Signed recommendations from plants that put the equipment, or our cleaning crews, to work in real production. We keep the originals — company, date and signature included.
Automotive · 24/7 operation
Continental Automotive Timișoara bought Cryonomic CAB 52 and COB 62 equipment from Meridian Invest in 2008 and ran it around the clock. In 2009 the relationship was extended with a service contract. The recommendation letter dates from 2009 — and its age is the point: the machines were already in continuous production by then.

Automotive · three shifts
Dräxlmaier Hunedoara ran a Cryonomic COB 62 bought from Meridian Invest for one year and eight months of intensive three-shift use without a single failure. The supplier also trained the personnel operating the equipment.

Beverages · cleaning service
The Brau Union plant in Miercurea Ciuc, today Heineken, confirmed in 2005 the cleaning work Meridian Invest carried out across its brewhouse, fermentation, filtration and bottling areas, and recommended us to other bottling and food-industry operations. This one is not a machine sale — we did the cleaning ourselves.

Bottling · working together since 2002
Romaqua Group / Borsec has worked with Meridian Invest since 2002 and confirmed in writing, in 2009, the cleaning services received, recommending us to other bottling and food-industry operations. This one too is about cleaning we carried out, not about a machine we sold.
Romaqua Group / Borsec · letter from 2009
These letters are old on purpose. They date from 2005 to 2009, and we show the dates rather than hide them: a recommendation written in the first year of operation, for equipment that is still running today, says something a fresh testimonial cannot. Two of the four describe cleaning work we carried out ourselves rather than a machine we sold — that difference is named on each card.
How HD Cleaners works
Send photos, a short video, or bring the real part. Tell us the surface, what has to come off, and what the result has to look like.
We name the technologies that fit the application, the alternative worth comparing, what each one needs in compressed air, water or power — and where it reaches its limit.
Where it matters, we run the application in the showroom or on your site, on your own part, before we recommend a machine.
Our promise
If none of our six technologies is right for your application, we will tell you so and explain which method is.
Including when that means you do not buy anything from us. A machine that does not solve your contamination costs you far more than the sale is worth to us.
Technologies
Deep cleaning with superheated dry steam, using little water and no process chemicals in suitable applications. Heat helps loosen grease and support hygiene-critical cleaning, while temperature, contact time and surface compatibility should be matched to the application.
Recommended for
Food & Beverage, HoReCa, Healthcare Environments, Automotive
Non-abrasive cleaning that sublimates on contact. Zero secondary waste. Less disassembly required. Production continues during cleaning.
Recommended for
Manufacturing, Heavy Industry, Electronics
Precision removal of rust, oxide, paint and coatings using focused laser energy. Cleaning without mechanical contact. The effect on the substrate depends on the laser type, the material and the process parameters; on sensitive surfaces we recommend validating on a sample first.
Recommended for
Automotive, Aerospace, Metal Fabrication
High-pressure abrasive surface preparation. Sand, water, or hybrid methods for demanding industrial applications.
Recommended for
Construction, Marine, Industrial Maintenance
Industrial pressure systems for heavy contamination, large-area cleaning, and exterior applications.
Recommended for
Facility Management, Construction, Municipal
Tank-based precision cleaning using ultrasonic cavitation. Reaches every surface and cavity on complex geometry parts.

Tell us your problem
Choose the problem closest to yours. We'll show you which technology we would test first, the alternatives worth comparing, what each method requires, and where it could reduce cleaning time, labour or downtime.
Or browse the equipment
Browse our equipment by cleaning method and application. Compare the available models, see what each category is designed for, and request a quotation or demonstration when you are ready.
The catalogue holds 106 machines. Some appear in two categories — steam machines used for car detailing, for example — which is why the category counts add up to more.

Documented results for the technologies we represent. These are not HD Cleaners customers, and we do not present them as ours — they show what the method can do when the application suits it.
8 hours → 30 minutes
Varec makes rubber-to-metal parts and used to clean its compression moulds by sand blasting, five days a week — the abrasive eroded the moulds and left secondary waste to collect. With dry ice the moulds are cleaned in place while still at 300 °C: from eight hours to roughly 30 minutes.

8 hours → 2 hours
At the General Mills plant in Hannibal, Missouri, cleaning the production-line equipment dropped from eight hours to two, without disassembly. Previously the line was shut down for one or more shifts while operators cleaned by hand.

300,000 → 130,000 litres a year
Chemiepack packs liquids and powders and used to clean its lines with pressurised water. After switching to dry ice, annual wastewater fell from about 300,000 to 130,000 litres, and cleaning that took two people is now done by one. The machines can keep running while being cleaned.

Every figure above belongs to that one documented case. Your surface, your contamination and your cycle time will give a different number — which is why we would rather test your part than quote someone else's result at you.
Showroom & Training
Visit our showroom in Miercurea Ciuc to compare the technologies that are relevant to your application. Where possible, bring your own part or cleaning problem: we can define what a successful result should look like, test the most suitable methods and show you where each one works — and where it reaches its limits.
Financing & Rental
Professional equipment leasing. Flexible terms. Fast approval process.
Rent any duration. No long-term commitment. Full support included.
Test first. 100% of rental payments offset against final purchase price.
Frequently asked questions
Send us a few details, photos or a short video of the application. Within one business day, a technical sales consultant will review it and come back with the next best step — additional questions, a first recommendation or a proposed test.
