HL Series-3

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 kitchens,...

HL Series-4

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 Temperature...

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 compressed...
