It&#8217;s used to prepare the raw materials that go into the company&#8217;s deodorizing products.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/monovate.net\/en\/wp-content\/uploads\/resin-to-stainless-tank-new.jpg\" alt=\"The newly installed 500L stainless tank\" \/><figcaption>The newly installed 500-liter stainless tank, fitted with two mixer units<\/figcaption><\/figure>\n<p>Before this upgrade, the company used a resin tank. Over years of use, the resin hardened, cracked, and picked up scratches on the interior. Grime worked its way into those scratches and dents, which they managed by relying on antibacterial agents. On top of that, colored products containing colorant would stain the resin itself, and as the material degraded, cleaning only got more time-consuming.<\/p>\n<p>The old mixer was a simple propeller type. Run it hard, and the liquid surface would churn and splash over the sides \u2014 which meant they always had to hold back on mixing intensity, and handle the equipment carefully.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/monovate.net\/en\/wp-content\/uploads\/resin-to-stainless-tank-old.jpg\" alt=\"The previous resin tank, same 500L capacity\" \/><figcaption>The previous resin tank \u2014 the same 500L capacity as its stainless replacement<\/figcaption><\/figure>\n<h2>Behind the Decision to Upgrade<\/h2>\n<p>MONOVATE had already supplied this customer with boiler equipment and a temperature-controlled tank around five years earlier, and the idea of eventually replacing the resin tank had been on their minds ever since. Budget constraints kept pushing the decision back, until this year, when they finally moved forward.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/monovate.net\/en\/wp-content\/uploads\/resin-to-stainless-tank-boiler.jpg\" alt=\"Boiler and temperature-controlled tank equipment delivered around five years earlier\" \/><figcaption>The boiler and temperature-controlled tank equipment MONOVATE delivered roughly five years earlier<\/figcaption><\/figure>\n<p>For the mixer, MONOVATE&#8217;s sales team recommended a Bernoulli-flow mixer as a versatile, all-purpose choice. Seeing it run in person \u2014 and confirming that the liquid surface stayed calm even at speed \u2014 was enough to convince them. Because a Bernoulli-flow mixer can run fast without splashing, it may also come in handy down the line if they need to work with ingredients that are harder to dissolve.<\/p>\n<p>MONOVATE also proposed a larger 1,000-liter tank, but the customer opted to keep the original 500-liter capacity, allowing for a straightforward, drop-in replacement without changing their batch sizes. For the material finish, they chose an electropolished interior \u2014 a high-grade surface treatment that uses electrical current to smooth the surface at a microscopic level, reducing residue buildup \u2014 specifically to improve sanitary performance and resist grime.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/monovate.net\/en\/wp-content\/uploads\/resin-to-stainless-tank-test.jpg\" alt=\"Water test showing a calm surface even at high mixing speed\" \/><figcaption>A water test: even at high speed, the surface stays calm rather than churning<\/figcaption><\/figure>\n<h2>What They&#8217;re Expecting from the New Equipment<\/h2>\n<p>With stainless steel \u2014 and an electropolished finish on top of that \u2014 they expect far less risk of grime working its way into scratches, the way it did with resin. Without colorant soaking into the surface anymore, cleaning should get considerably easier.<\/p>\n<p>Because stainless cleans more thoroughly, they also expect improved cleanability to open the door to manufacturing a wider range of products on the same equipment.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/monovate.net\/en\/wp-content\/uploads\/resin-to-stainless-tank-iqoq.jpg\" alt=\"IQOQ (installation and operational qualification) in progress\" \/><figcaption>IQOQ (installation and operational qualification), confirmed on site with MONOVATE&#8217;s technical staff present<\/figcaption><\/figure>\n<h2>What&#8217;s Next<\/h2>\n<p>If this first stainless tank performs well, the plan is to keep converting more equipment to stainless over time, budget permitting. Capital investment decisions like this haven&#8217;t always been easy to commit to \u2014 which is exactly why they&#8217;re taking the approach of installing one unit first, confirming it works, and then expanding gradually from there.<\/p>\n<hr>\n<p><em>Editor&#8217;s note: It genuinely meant a lot to us that this customer thought of MONOVATE again for this upgrade, five years after our first project together. Picturing how much more comfortable day-to-day work will feel with better cleanability and mixing performance made us feel invested in the outcome ourselves.
