Code Constructed National Board Registered storage tank
CEMLINE® tanks are
designed and constructed in accordance with the latest A.S.M.E. Code
regulations using pressure vessel quality plate and certified welders.
An A.S.M.E. code certificate is provided and all vessels are registered
with the National Board of Boiler and Pressure Vessel Inspectors. Vessels
are normally built for 125 psig maximum working pressure but can be
furnished for pressures as low as 15 psig and as high as 500 psig.
CEMLINE has held
the original patent for STONESTEEL hydraulic cement lining since 1936.
This proven design prevents rust and corrosion common to metal tanks.
The STONESTEEL lining is applied as a continuous arch against the metal
wall and has the same thermal coefficient of expansion as the steel
tank shell. This is an advantage in that even extreme and rapid temperature
changes have no ill effect on the STONESTEEL lining. Tanks 36" and larger
in diameter are provided with wire mesh welded to inside tank walls
to insure a permanent bonding of the lining to tank.
CEMLINE SPH water
heaters can be constructed with a solid 316-L grade stainless steel vessel.
316-L stainless steel is acknowledged as the most corrosive resistant
stainless used for water heaters. A CEMLINE SPH water heater with a
316-L stainless steel vessel will give the customer many years of service
without concern of corrosion or tank failure.
steel threaded connections
tanks are manufactured with stainless steel threaded openings and all
non-corrosive piping. This design insures that the water never contacts
corrosive metal, and offers the owner the guarantee of exceptionally
long tank life.
3" Fiberglass insulation
CEMLINE heaters are
furnished with 3" thick Fiberglass insulation. This high quality insulation
conforms to the latest ASHRAE standards for commercial water heaters,
and has proven to be an extremely reliable means of minimizing heat
20 gauge steel jacket with hammertone enamel finish
units are neatly and attractively covered with a 20 gauge steel jacket
over the Fiberglass insulation. The jacket protects the insulation,
and is professionally painted with superior quality enamel to allow
the added importance of an easy to maintain surface.
Structural I-beam support Skid Base
CEMLINE heaters are mounted on structural I-Beam support skids
designed as a permanent base. This skid is pre-engineered to allow correct
support for the heater.
ASME Relief Valve- pressure and temperature
packages are provided with ASME pressure-temperature relief valves sized
to relieve the total BTU input of the heating coils.
heaters are provided with a digital tank thermometer with LCD readout
to monitor temperature of the water within the vessel. The thermometer
will be console mounted with a compound steam pressure gauge to monitor
steam pressure at the coil. (Units heated with boiler water will be
supplied with a boiler water thermometer to monitor temperature of incoming
Water Pressure Gauge
packaged heaters are supplied with a large, easily readable pressure
package units are offered with several options of control, depending
on specific requirements or desired preferences. Valves can be provided
of the pneumatically operated or electronic type.
Brazed Plate or Plate and Frame Heat Exchanger
Control valves are factory sized and installed so the owner may rest
assured that the valve provided with the heater is correctly fitted
and engineered to meet the specific job requirements.
Plate heat exchangers are extremely efficient allowing for close or
cross temperature approaches between the boiler water and heated
water. Cemline offers a brazed plate style for single wall
applications and a plate and frame style for double wall
Integral bronze circulator
fractional circulating pump circulates the water over the coil, thereby
maximizing the heat transfer efficiency of the coil. The pump is selected
to match the operating conditions of the water heater.
Single safety system
This is an over-temperature safety system which will close the main
control valve upon an over-temperature condition. This system utilizes
a digital electronic adjustable thermostat with LCD readout which monitors
the temperature of the water and if an over-temperature condition is
detected, sends an electric signal to the valve, thereby closing the
valve. This system requires a 120 volt 5 amp circuit.
Solid State operating control
The CEMLINE CEM-TROL® incorporates operating and limit functions in one solid state controller. The controller features a LED display of the temperature and on board operating PID temperature control along with high temperature safety cut offs and alarm indications. The CEM-TROL® simplifies the control of the Packaged Water Heater, enhances the look of the product, and follows industry trend to solid state controls.
An alarm bell is furnished to sound an alarm in the event that either the primary or secondary high temperature limit is exceeded. An alarm silencing relay allows manual pressing of a button to silence the alarm bell, but red warning light remains on until the alarm condition is corrected.
This feature allows the Packaged Water Heater to be started or stopped from a remote location. Typically this would be accomplished from the Building Automatic System (BAS). Requires a dry contact suitable for 24 Vac and 1 amp.
