The Thermaxx name is synonymous with steam systems. Removable reusable insulated jackets are seen in wide use today bearing the Thermaxx name in boiler rooms all over the USA and abroad. But what about keeping the cold out?
Thermaxx offers insulated coolant jackets that will do just that. During the cold winter of 2013 the Midwestern and Southern states around the US experienced record freezes that lasted for weeks, the Polar Vortex had hit our nation hard and industries were sourcing a way to help protect sensitive equipment and pipe systems. Freeze protection was a must and when Thermaxx was asked for solutions we delivered with our Antifreeze line of insulated jackets.
The Antifreeze line is very similar to our regular hot side of insulated jackets. In fact the same materials are used in different ways to achieve a custom fit insulated jacket designed to keep the cold out. Aerogel insulation combined with superior PTFE/Silicone-coated Fiberglass jacketing (sometimes combined with needled fiberglass) offers unique insulating properties to protect each component. In combination with an electric heat trace cable, provided by the end user, the Thermaxx Jacket has proven to be a winner in this area of need.

Multiple types of pipes are prone to freezing for various reasons. Luckily, from heat tapes and firm seals to insulation jackets, many solutions are available. If you’re looking to prevent different types of pipes from freezing, consider the following options.
Preparing all hot water pipes for cold weather is essential. Start by checking for leaks and ensure the pipes are working properly. Seal any leaks with caulking to ensure your pipes are working properly.
Another solution is to invest in heat tape — wire that has heating elements to help warm pipes up enough to stop them from freezing.
Insulating hot water pipes is also critical. One of the most effective ways to do that is by investing in hot water pipe insulation jackets. Insulation can help keep heat in, however, sometimes insulation alone is not enough. If exterior temperatures are low enough, a heat source may be required to maintain temperatures above freezing.
For outdoor boilers, you might consider building an enclosure around all or part of the equipment to help keep it from freezing — especially if you install an external heating source.
You should also install appropriate heat tracing systems and drain any unnecessary lines when the boiler is not in operation. Remove snow and ice from the outdoor boiler periodically.
Insulation jackets are another easy option to help prevent outdoor boilers from freezing during the winter. Get insulated pipes for outdoor boilers with easy-on, easy-off insulation jackets. Insulation jackets will also help distribute an even temperature throughout the unit, and decrease the amount of energy the heater tapes will require to operate.
For exterior condensate lines, you can consider several options to prevent freezing. If you make the drain pipe shorter, the water will have less space where it can freeze. You will also need to check the pitch of your condensate lines in order to ensure the condensate drains properly. Finally, you will want to keep snow or any other obstructions away from the drain line so it cannot cause freezing. Using weatherproof insulation allows you to prevent freezing in your exterior condensate lines.
Our antifreeze insulation jackets are high-quality and offer the insulation you need for various types of piping. Our antifreeze jackets can help reduce the amount of British Thermal Units (BTUs) the fluid will lose to the ambient air. The science behind our insulation jackets makes them a practical choice for a variety of industries.
The overall concept for designing your Antifreeze Jacket is achieved by closely working with your engineers and our design team. Industry Engineers along with our trained sales staff gather information about the component being protected. Weather is always a concern, questions like normal area winter temperatures, on site location, wet or dry location and even wind speed can determine which materials we use. If a heat trace cable is being used on the component before jacketing we will ask what type, size and wattage to once more guarantee the proper design and fit for your Antifreeze Jacket.
Your company can rely on Thermaxx to deliver the best designed Antifreeze Jacket system. We offer a full warranty on our products and also offer on-site field measuring when needed. We want to keep you warm this winter!
Antifreeze insulation jackets are designed to protect outdoor pipes, valves, water system components, and equipment from freezing. Our durable outdoor insulation covers are specifically designed for protection from the cold. When needed, we also provide belt loops, sewn to the interior side of the jacket, to allow for easily “snaking” of heat trace material. This allows for easy removal when component needs to be inspected or maintained. When the jacket is removed, the heat trace comes off with it!
✔︎ Protect Your Backflow Preventers
Backflow prevention devices perform a critical function by protecting water from contamination. Backflow preventers such as atmospheric vacuum breakers, and pressure vacuum breakers are often located outdoors and could be at risk for breaking due to freezing. Installing an antifreeze insulation jacket can mitigate this risk to help keep drinking water safe and avoid costly repairs and replacements of backflow preventers.
✔︎ Extend the Life of Water Meters & Air Release Valves
Water meters may be utility company property, but it is often the customer who is billed for water meter repair and replacement. Water meters have a reputation for freezing and breaking but can easily be protected by insulation covers. Air release valves are important water system components that are often also at risk for freeze damage.
✔︎ Insulate Components from the Elements
✔︎ Additional Components to Insulate:
✔︎ Stop Wasting Energy
Antifreeze jackets will keep the cold out and keep heat from radiating away from equipment so you can reduce your gas or electricity consumption.
✔︎ Avoid Damages Due to Freezing
Outdoor valves and pipes may be at risk for bursting due to expansion within the pipes if the water freezes. Burst pipes can result in costly repairs and expensive cleanup and damage control. Other outdoor equipment may also be at risk for sudden breaking due to freezing. Freezing and thawing causes expansion and contraction that can degrade equipment integrity. Antifreeze jackets can provide insurance against the harsh elements.
✔︎ Reduce Service Interruptions
A burst pipe or broken backflow preventer can cause an entire water system to be put temporarily out of commission. If run cold, an outdoor motor could blow and cause an outage. Severe cold can cause service interruptions in many ways. Exterior insulation jackets can help keep service running smoothly despite the harshest winter conditions.
✔︎ Remove Easily for Servicing
Our insulation products are specifically designed to be removed and replaced in a matter of a few short minutes. Thus, our removable outdoor insulation have all the benefits described above without making the maintenance of your equipment more difficult.
✔︎ Save Money
By saving time, saving energy, and reducing the risk of costly damages and outages, our outdoor insulation saves you money.
