Welcome to Hydro Navitas Solutions

Thank you for finding your way to our website.

In an ever-changing world, it’s good to know we are all doing the right thing, but sometimes this is not easy. Here at Hydro Navitas, we hope to make your life a little easier as everything you find here is 100% biodegradable, non-toxic, non-corrosive, free of toxic chemicals and environmentally friendly.

We know we need to stop using harmful chemicals. If you are here, perhaps it’s because your existing firefighting agent, fire suppression systems, decontaminant or odour removal product contains one of those chemicals where their name seem to defy belief, or maybe you are looking for something that offers more benefits than just features, either way, we can help you. We need to save this beautiful planet of ours. All the products and solutions you will read about here are 100% naturally made and been developed over many years.

We hope you find what you are looking for. Below is a snapshot of each section and what we have to offer. If you don’t find the answers, just call.

move away from toxic chemicals to something altogether more natural, 100% natural



Below you will find a snapshot of our divisions. Each provides you with a range of 100% Naturally Made, Non-toxic, Non-corrosive, Free of Toxic Chemicals and 100% Environmentally Friendly solutions.

Please have a good look around. Each section offers you an incredible level of both features and benefits. We believe that many of these you will not find elsewhere; however, if you have any reason to question any of our claims and you read them and think, really?!?! Let us come and show you. Trust us; there is nothing better than seeing what we have to offer in the flesh.



Cold Fire Firefighting

We have a range of Cold Fire wetting agents for firefighting. Each offers the same incredible extinguishing abilities and will provide the very best firefighting wetting agent. You can rest assured Cold Fire is not be one of the many firefighting agents being removed across the globe due to their high level of toxic chemicals. Cold Fire is and always will be GREEN and 100% Naturally Made.

We offer a premix Winterised version of Cold Fire. Depending on your requirements, this remarkable blend can work between temperatures from -28°C (-20°F) and right down to a rather chilly -53°C (-65°F).

So we supply Cold Fire to the following industries;  Commercial. Emergency Services. Motor and Marine. Aviation and Military.



Custodian Fire Suppression

Here you will find out why many manufacturers are now swapping out their existing AFFF (aqueous film-forming foam) and moving over to Cold Fire in their fire suppression systems. For many years their options have been limited to Water, AFFF or Dry Powder! Now there is another option, Cold Fire.

Motorsport has been using Cold Fire for many years. IndyCar, NASCAR, Drag Racing, Now for the first time ever, the Fédération Internationale de l’Automobile (FIA) use Cold Fire in one of their Holmolagation FIA 8865 in-car vehicle suppression systems.

From in-car vehicle systems to fixed automated cannon fire suppression systems. One of the hardest-hit industries for fires has been Waste Recycling. Today, many sites are protected by systems using Cold Fire. It is one of the only firefighting agents that can deal with and extinguish lithium-ion batteries. There are so many more areas where fire suppression systems can benefit from Cold Fire. Some of these might just surprise you.

Fire suppression comes in many forms. We can supply small portable Bag-on-Valve units right through to fully automated systems that monitor heat variations across an area. But sometimes suppression can mean stopping the material igniting in the first place. We can do that also.


We have another truly remarkable product called Fire Block that protects nearly anything it is applied to. This simple to use pre-mixed product is also 100% naturally made. It protects against FLAME SPREAD and SMOKE DEVELOPMENT. All you do is spray and allow it to dry. Like everything we provide, it has also been through some of the hardest tests for this type of product. US NFPA 225 & ASTM-E84 tests are large scale tests for flame spread and smoke development, this has also been independently tested by SGS (Standard Global Services) the world’s leading testing groups for Class A materials. It also has NFPA701 (fabric retardancy) for textile fabrics. It also has BS 5867-2:2008 Part 2 (Fabrics for curtains, drapes and window blinds) and BS 7177:2008 + A1:2011 (Flammability Testing of a mattress – Natural latex).

There are many new exciting developments happening in this part of our business, so pop back often for updates.



Acid-Stop Decontaminant

Acid-stop was developed for industries that on a daily basis use some of the most toxic and caustic chemicals. Sometimes through no fault of the manufacturing process, these can spill, spray or leak from seals during the production process. As you can imagine, the people who work with these chemicals dress in the type of protective clothing that, on any other occasion, you could mistake them as astronauts. They have some of the highest levels of safety procedures, but they still have to deal with this and need a product that can safely minimise this risk.

There are products on the market that work with the above and they use different methods to achieve similar results. Some use chemicals that react with the spill and produce a less harmful finished chemical, others use highly porous minerals that enhance absorption and provide neutralising characteristics and, some use the process of ‘wicking’ and remove the chemical from the surface. Acid-stop is different from all of these. Our range can be carried on you in small units, or used via our range of pressurised sealed units or pump-to-use units.

Acid-stop is different from all of these, In that, it immediately decontaminates the affected area and/or person. Our range is powerful enough to be available in belt-mounted small canisters for personal use or used via a range of pressurised sealed units or pump-to-use units.

Due to the unique nature of Acid-stop, we were fortunate to get government funding to carry out extensive trials. We were incredibly excited to learn that not only did Acid-stop neutralise acids, but it also neutralised alkalines.

This places Acid-stop in a unique list of products that can work across the whole pH Spectrum (0 – 14) and neutralise both ACIDS and ALKALIS.


Acid-stop was developed for industrial applications, but you may be aware that the UK has one of the highest cases of CORROSIVE attacks in the world; this is both startling and true. London has the ominous title of the ‘acid attack hotspot‘ of the western world, and the youngest victim was just ten years old. Just writing these words for our website is incredibly concerning, but the level of devastation an attack brings to everyone involved is immeasurable and due to the method of the attack and its visible results, last a lifetime. Due to the complete safe-to-use nature of Acid-stop, the UK Police are looking at possible front-line use to help with these types of attacks.



Green and Clean Solutions

Here you will find a range of cleaning, water decontaminants and bio-stimulants all designed to support nature. We are trialling something new and exciting called BioPlus 600™. As diseases are ravaging our incredible range of trees across the UK, we have something that we hope will give them a boost and support their immune system to fight against diseases like Ash Dieback (Chalara fraxinea). If we don’t save our trees and the rivers, our landscape will change forever.
