The 335 DHW hot-water jetting unit from NLB Corp. has a dependable triplex pump capable of 15 gpm at 3,500 psi; a Kubota v3600 66 hp engine provides the power in a direct-drive configuration that eliminates the PTO and PTO maintenance. Its 700,000 Btu burner unit addresses the demands of the many cycles, long hours, and transportation requirements in the life of a typical hot-water unit. An overhead-mounted water tank is easy to winterize and has integrated water lubrication lines and a 75-micron inlet strainer that can be rinsed or cleaned, eliminating the traditional filter. A rupture disk has also been eliminated from the unit’s design and replaced with a self-resetting pop-off valve, saving time and money for the operator. 800/227-7652; www.nlbcorp.com.
