Hydroexcavation tools offer efficient digging and debris removal, especially in challenging environments. These tools often feature hot-water systems to improve performance in colder climates or clay-heavy areas. Innovations like advanced water heaters and automated water flow systems enhance safety and operational efficiency by offering precise control over water pressure and flow rates. Portable and compact solutions are also available, providing flexibility for smaller jobs while maintaining the necessary power for deeper excavation tasks. Take a look at some product options below.
Dynablast HV590FLS-12VRED
The HV590FLS-12VRED hydrovac water heater from Dynablast produces 590,000 Btus with an output temperature of 175 degrees F at 7 gpm. An optional electronic 12-volt thermostat can hold a more precise water temperature. The unit is suitable for colder climates and improves digging in clay-filled areas, according to the maker. It enables fuel savings of 3/4 gph and a weight reduction of 250 pounds over the current 690,000 Btu model. It comes with extract transform load certification for safety, which also includes certification on the coil for higher efficiency and heat transfer, stainless steel target plate for increased coil life and serviceability with momentary override control. 905-867-4642; www.dynablast.ca
Easy-Kleen Pressure Systems hot-water heaters
Oil-fired hot-water heaters from Easy-Kleen Pressure Systems are install-ready for vacuum and hydrovac trucks. These rugged, heavy-gauge frames offer durability even in severe road and weather conditions, according to the maker. A full range of heater options is available including dry steam, redundancy packages, schedule 80 and 160 stainless steel or A53 boiler pipe, and fine-tuned temperature and flow control systems. Their coils are manufactured in-house. (Canadian Registration Number boiler approved coils now available). These heaters can be mounted in a cabinet or supplied as a completed cabinet unit. 800-315-5533; www.easykleen.com
Pressure Lift HydraBore
The HydraBore equipment attachment from Pressure Lift fits on the end of any vacuum hose used for hydroexcavation. Place the stinger on the far end of the tool, then hook the HydraBore to the end of the snorkel. Connect the air supply and high pressure water supply systems, turning the air on first, then the water supply, open the vacuum system and begin hydroexcavating. Contractors no longer need additional manpower holding a lance-powered high-pressure water supply. It also removes the need to wear a rain suit to remain clean as the user begins every job from several feet away using the lanyard or from the safety of the side of the rig at the other controls. Once hydroexcavation begins, the user can control the boom in an up-and-down motion, then when the HydraBore becomes submerged, can excavate faster and go deeper than before, reducing wear and tear on vacuum equipment. 866-504-6596; www.pressurelift.com
RNV Hydrovac2
The RNV Hydrovac2 can be placed on an RNV-approved 6-cubic-foot steel construction-grade wheelbarrow to create a portable hydrovac. It can vacuum down vertically to 12 feet to convey effluent sludge, sand and small aggregate. It can be combined with a pressure washer or air spade for another excavation solution. The unit weighs 42 pounds, requires a 120-vac, 15-amp power outlet and will run on a 2,200-watt generator or inverter. 607-786-2139; www.rnvac.com
TRUVAC DigRight Technology
TRUVAC’s DigRight Technology offers a sophisticated variable water flow pump, designed to precisely tailor the water flow to the specific requirements of the nozzle in use. The pump operates within strictly defined parameters for optimal performance without risk of damage to the nozzle, surrounding utilities or the pump mechanism, according to the maker. Should water pressure inadvertently exceed predetermined boundaries, a relief valve activates for safety. The system permits programming of three distinct pressure upper limits, which operators can modify on the fly with a handheld wireless controller, eliminating concerns over accidental limit breaches. It safeguards against the accidental disruption of underground utilities and ensures operator safety. The automation of water flow adjustments according to nozzle size is designed to provide smoother and more effective hydroexcavation. 815-672-3171; www.truvac.com
