Tankless Eye/Face Wash Heaters provide warm water intended to supply safety fixtures. The heaters uniquely perform in applications with low line pressure, while still accommodating ANSI standard flow rates. The durable plumbing components withstand higher pressures which result in a longer service life, while ensuring the delivery of precise output temperature within ±1°F. Keltech's durable electrical components withstand power abnormalities found in industrial environments and ensure tepid water standards are never exceeded (100°F), with its three-tier anti-scald protection. Keltech Tankless systems do not require the installation of an emergency thermostatic mixing valve. The NEMA 4 Enclosure (General Area) is durable and waterproof. NEMA 4X Enclosure offers the same features as a NEMA 4 Enclosure, with the added benefit of corrosion resistance. CLE-Series units are also suited to applications where 3 Phase Delta 480V or 600V, 50/60 Hz is required. Construction Temperature Controller Keltech's PID Temperature Controller is more energy efficient and reliable than traditional microprocessors using staged elements. 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. Electrical The CLE-Series requires only one service feed per unit. Includes internal fusing as standard. Internal fusing provides superior protection. Keltech protects both sides of each heating element with fusing. Cabinet Enclosure The wall- or floor-mounted standard cabinet enclosure is NEMA 4 rated and made from 16 gauge mild steel and powder coated with ANSI 61 gray, corrosive resistant paint. The optional NEMA 4X enclosures are for harsher environments and made from 16 gauge 304 stainless steel. The NEMA 4X enclosure can also be specified with 316 stainless steel. Independent Safeties The controller alarm sends a signal to disconnect power to the elements if the temperature reaches 90°F (32°C). The internal thermostat with auto reset high limit switch ensures that when the temperature limit is reached (factory preset at 80°F/27°C), the unit will power down a bank of elements; when the temperature returns to the set point, power is restored. The surface mounted bi-metal thermostat with manual reset acts as a fail-safe and must be manually reset before power can be restored to the elements if the temperature limit is exceeded. Temperature Safety Values: Internal thermostat with auto reset high limit switch: 95°F (35°C) Surface mounted bi-metal thermostat with manual reset: 100°F (38°C) Code Compliance and Certifications Lead-Free Products marked with the Lead-Free logo comply with the Safe Drinking Water Act (SDWA) requirements of a weighted average of less than 0.25% lead content on wetted surfaces of pipes, pipe fittings, plumbing fittings, and fixtures. Heating Element Each heater features a heavy duty, low watt density, incoloy 800 sheathed resistive element. The Keltech design ensures greater protection, durability and resistance to scaling from hard water because water is only heated when flowing; this means sediment will not collect in the heat exchanger. ETL listed to UL499 ETL listed to UL 50E ETL listed to NFPA 496 (Requires EXP2 Option) Solid State Relays The liquid cooled solid state relays provide silent switching, which has a fast response and works in conjunction with the PID controller to infinitely modulate and add to the life of the heater.

Product Options Fused Disconnect Internal fused disconnect interlocks with enclosure door when energized, prohibiting access to a live cabinet. Select the FDS option for an additional level of safety and convenience at the heater location. Alarm Selections Keltech offers two levels of building communication alarm options. The AL3 option provides dry contacts that open to signal flow >1.5 gpm has activated the heater. The AL3-SL option provides these dry contacts and additionally activates a local audible and visual alarm on the heater. Alarms activate at 1.5 gpm flow or greater. Freeze...
