Extreme and Hazardous
Environments
Tough Enough for the
Most Extreme Environments on Earth
Keltech tankless water heaters are built to last. We design
and manufacture each custom built heater using rugged industrial
strength components made of high quality copper and brass construction
to extend the life of the heat exchanger.
 |
|
To protect your investment,
the entire unit is safely cocooned inside a NEMA certified
stainless steel enclosure. It’s a commercial grade,
self-contained, tankless water heating solution designed
to meet your specs and the challenges of performing in
the most rugged, most extreme industrial and corrosive
environments. It’s the perfect water heating solution
for the most extreme environments. There are no exposed
or moving parts. There are no mixing valves and no re-circulation
loops. |

Keltech tankless water
heaters are tough enough to perform in Canada, Alaska,
and in the Rockies where temperatures can get as cold as
-30ºF. |

|
Keltech products are
tough enough to survive with no or low maintenance in caustic
or corrosive environments like strip mines, petro-chemical
sites, or industrial manufacturing facilities where airborne
dust, debris, and fluids shorten the life of other types
of machinery. |

CONDITIONS

NEMA 4X ENCLOSURES MADE FROM STAINLESS STEEL
For the most extreme
environments, Keltech uses NEMA 4X enclosures. NEMA 4X water-tight,
corrosion resistant enclosures are constructed from stainless
steel for indoor and outdoor use and provide an additional level
of protection for the heater against corrosion. They also provide
protection for the heater against falling dirt, rain, sleet,
snow, windblown dust, splashing water, hose-directed water, and
the external formation of ice on the enclosure. NEMA 4X enclosures
also protect people against access to hazardous parts of the
equipment.
COMPUTER INTERFACE OPTION FOR REMOTE MONITORING
Extreme environments
may not allow on-site access to the heater. In these instances,
Keltech can provide a computer interface option to keep your
employees safe. A LED controller that can be programmed and monitored
by connecting it with a personal computer or programmable logic
controller (PLC) via serial communications.

EXPLOSION PROOF PURGE
SYSTEM
For extreme environments that require
explosion proof protection, Keltech’s tankless water
heaters in NEMA enclosures can be equipped with a purge system.
Heat, moisture, dust and corrosion are eliminated by providing
the enclosure with a slow but continuous flow of inert gas
or dry compressed air. This process removes flammable gases
or prevents the accumulation of ignitable dusts within the
protected enclosure.
The Purge System:
- Reduces heat build-up in the enclosure
- Inhibits metal
corrosion and reduces moisture buildup
- Provides continuous
monitoring capabilities
- Eliminates large, heavy explosion
proof enclosure

FREEZE PROTECTION
Keltech’s freeze protection option protects
the heater and internal components in sub-zero conditions. It
allows the unit to function at –30ºF with an 11 mph
wind. Freeze protection is only available with NEMA 4 or NEMA
4X options.
GROUND FAULT
This safety feature detects electrical leakage
from external sources to protect the equipment, electronics and
the heat exchanger from being damaged in the event of a power
fault.
DE-IONIZED
WATER SOLUTIONS
Keltech’s tankless hot water heaters
are A-rated for de-ionized water, chlorides, saltwater solutions,
reverse osmosis water, caustic alkalis and many other applications.
All Keltech large commercial/industrial heaters are available
with an optional Teflon® like fluorocarbon protective coating
on internal passageways. Fluorocarbon coatings protect the heat
exchanger from corrosive environments.

WHEN CORROSION IS A CONCERN
The TE2 Protection System protects
all heat exchanger surfaces that come in contact with heated
fluids. The caustic and acid resistance of TE2 is very good and
the solvent resistance is excellent. To protect the heater from
corrosion, Keltech constructs its electric heating elements of
electro-polished and passivated Incoloy 800 sheathing. All plugs
and fittings are stainless steel.
WHEN FLUID PURITY IS CRITICAL
Keltech has developed a unique
and exclusive protection system that meets the requirements for
ultra pure water. To conform to FDA regulations governing direct
food contact applications, the TE3 Protection System includes
a fluorocarbon coating similar to the FDA approved Teflon® PFA
on all surfaces and internal passageways that come in contact
with the heated media. This is critical when you need to heat
de-ionized water or to heat reverse osmosis water.
ETL/cETL CERTIFIED
The registered label for ITS Corporation,
an international safety testing laboratory that tests and certifies
Keltech tankless water heaters to UL499 and corresponding CSA
standards. Keltech tankless water heaters are ETL/cETL certified.
