Insulated Water Tanks for Cold Weather

PHIL Insulated Water Tanks for Cold Weather Climates are specifically designed to house the water pump and all necessary valving within the confines of the water tank footprint. Additional enhancements include a three-layer sandwiched double-wall skin providing excellent insulation, minimizing the chances of internal water freezing. For use in extreme environments, such as when our tanks are used in building ice roads in Alaska and in Canada, which meant to keep the water and plumbing from becoming frozen.

For the most versatile water tank in cold weather applications, PHIL has engineered unique versions that are insulated to protect against frigid, arctic environments, optionally with a fully integrated heating element included. PHIL engineers each tank to maximize its size based on the truck it is going on - we do not undersize our tanks to generically fit multiple trucks - that's not our style. We offer, what we believe to be the safest, biggest, most stable and trouble-free water tanks available, globally. Our reputation and over a half-century of success in the off-highway truck customization market proves that we achieve what we set out to do.

Our high-volume cold weather water tanks range from 6,000 to 60,000 gallons + for most articulated and rigid frame off-highway trucks to assist with dust suppression, building ice roads, fire protection, road construction, wash down, and other applications.


We consider safety paramount, which is why we build safety into every corner of our water tank design.

The interior of each PHIL water tank is engineered to minimize confined space concerns. Our patented external/internal access door system incorporates front and rear bulkhead access man doors, top of tank access points, and built-in interior access baffle doors. This allows safe, easy internal access so service personnel can move comfortably and safely throughout the tank interior with an unrestricted passage from front-to-rear.

Our water tank's external construction includes a unique flat top that is sloped at only 1 1/2 degrees. By building the top flat, it minimizes the chances of losing one's footing. In addition, our exclusive integrated lifting eye design provides precise placement for perfect balance when raising the tank.


We build our Water Tanks using the highest strength steel available - and when put into corrosive environments, we offer enhanced corrosive-resistant steel or sacrificial anodes to provide long tank life. In fact, the steel we use is five times stronger than ordinary mild steel and a minimum of three times stronger than steel typically used in water tanks. Use of this higher strength steel ensures you'll receive a tank with the lowest weight and greatest water carrying capacity.


Our patented fluid tank baffling system ensures solid vehicle control in any application. This exclusive anti-surge stabilizing system provides front-to-back baffling and a full-height/full-length center Bacbone™ structure. Internal baffling, in conjunction with the internal fluid surge stabilizers, minimizes side-to-side fluid movement for maximum vehicle stability at all normal haul road speeds.

The tank support structure consists of an exclusive exterior frame rail and cross bolster tank-to-chassis mounting system that parallels the truck chassis frame for a lower center of gravity. This ensures uniform chassis loading while providing a solid foundation for the tank-to-chassis interface. We use 165,000 psi minimum yield steel to provide the strongest, best subfloor structure on the market.


Our Water Tank comes equipped with an in-cab controlled water cannon that allows the disbursement of water from 90 to 150 feet with absolute control and accuracy. Long-wearing, specialized spray heads are rear-mounted and operate independently so you can run one, all, or any number in between to meet your needs. The entire tank plumbing system utilizes off-the-shelf Victaulic®/Gruvolk® style fittings throughout for easy maintenance.

The water pump system employs an exclusive and patented "Soft-Start/Soft-Stop" single combination hydraulic valve that allows you to safely start and stop the water pump at any engine RPM. If you need to suddenly turn the water on at full throttle, this system makes it possible to do so without causing damage to your pump.

The tank's exclusive "Variable Volume" adjustment allows you to adjust the water volume of the tank with a simple adjustment. On days when less water is required for controlling dust, etc., the water tank can be "downsized" to a lesser, pre-adjusted volume. Switching from full volume to a lesser volume is easily accomplished in less than five minutes.
