Standard Equipment
Tankless Water Heating Specifications
Keltech, Inc. 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.
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.
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.
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, 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)
