HL Series Designed to accommodate most commercial fluid heating applications where demand is ≤ 18 kW and total flow is ≤ 7 GPM (26.5 L-Min). For environments where lower activation flows are required, standard units are 0.5 GPM (1.9 L-Min) with options as low as 0.15 GPM (0.6 L-Min). Heaters are also suited to applications with single phase service or 3-Phase 208V, 240V and 480V. Standard units include a NEMA 1 enclosure, with NEMA 4 and 4X options available. Whether you need intermittent hot water, low flow control, booster heating or deionized water in schools, hospitals, or commercial...

PID Temperature Controller More energy efficient and reliable than traditional microprocessors, Keltech heaters hold temperature as demand changes regardless of incoming ground water temperature. Power is infinitely variable, with no fixed inputs. The PID controller makes it possible to modulate the amount of power applied to the elements while also dispersing the required power evenly across all elements. This unique feature increases the product’s life cycle. Simple Touch Operation Digital LED screen with touch pad for easy operation shows set point and output temperature. Precise...

Minimal Pressure Drop Keltech's best in industry low pressure drop reduces or eliminates the need and expense associated with adding pressure booster pumps. Durable Plumbing Assembly All units consist of brazed joints, brass and copper heat exchanger, industrial-grade flow switch & brass castings/fittings at all directional changes. Premium Materials All waterways consist of high-quality copper & brass construction tested to 300 PSI (20.7 bar). Robust lead-free brass castings and flanges are CNC cut from solid brass blanks for precision fit. High-quality copper & brass construction extend...

NEMA 4 Enclosures NEMA 4 enclosures are constructed for either indoor or outdoor use. The enclosure protects the components of the commercial heater from dust and water. Enclosures are made from 18 gauge electrogalvinized and powder coated steel with ANSI 61 gray, corrosive resistant paint. NEMA 4X Enclosures For harsh environments, NEMA 4X watertight enclosures are available for an additional level of protection. Enclosures are made from 304 or 316 stainless steel. Building Management Systems Integration Transfers control of the heater to a Building Management System (BMS). The heater is...

HL SERIES OPTIONAL FEATURES Explosion-Proof Purge System HL Series water heaters in NEMA 4/4X enclosures can be equipped with an explosion-proof purge system. The type of purge system determines the classification or division the enclosure will meet; HL Series use a system that conforms to Class 1, Division 2 hazardous area standards. Electrical components installed in NEMA 4/4X enclosures allow the system to be pressurized by clean instrument air or inert gas. Heat, moisture, dust and corrosion are eliminated by providing the enclosure with a slow but continuous flow of inert gas or dry...
