ASME 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.

STONESTEEL Lining

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.

Stainless Steel Vessel

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.

Stainless Steel Threaded Connections

CEMLINE SSH water heaters are constructed with solid 316-L stainless steel openings. This grade of stainless steel is chosen for its proven long life and corrosion resistance.

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 loss.

20 gauge steel jacket with hammertone enamel finish

CEMLINE packaged 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

CEMLINE packages are provided with ASME pressure-temperature relief valves sized to relieve the total BTU input of the heating coils.

Digital Thermometer

CEMLINE 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 boiler water).

Water Pressure Gauge

CEMLINE packaged heaters are supplied with a large, easily readable pressure gauge.

Control Valve

CEMLINE package units are offered with several options of control, depending on specific requirements or desired preferences. Valves can be provided of the pilot operated, pneumatically operated or electronic type. 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.

Brazed Plate or Plate and Frame Heat Exchanger

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 applications.

Integral Bronze Circulator

Bronze 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.

Alarm Bell

An alarm bell is furnished to sound an alarm in the event that either the primary or secondary high temperature limits are 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.

Remote Start/Stop

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.

BOILER WATER AS THE ENERGY SOURCE

STANDARD EQUIPMENT

CONTROL VALVE

Electronic Control Valve

Electronically operated control valves use a solid state temperature sensor which is wired to an electronic control module. The electronic control module has an adjustable set point. The control module compares the set point with the sensed temperature and sends an electric signal to a magnetic linear actuator on the control valve. The magnetic linear actuator modulates the control valve and regulates the amount of boiler water through the valve to maintain the set point of the controller. When the set point is achieved, the controller sends a signal to the valve actuator and the valve closes. In the event of high temperature or loss of building power, the limit control closes the electric power to the controller which closes the valve.

Two way Valve

A two way valve modulates from fully closed to fully open varying the amount of hot water circulated through the coil to maintain the desired output temperature. When closed the two way valve may cause a change in the heating water loop pressure.

Three way valve

A three way valve modulates from directing all heating water through the coil to directing no heating water through the coil, varying the amount of hot water circulated through the coil to maintain the desired output temperature. The pressure drop in the heating system will be relatively constant with a three way valve.

OPTIONAL EQUIPMENT

Double Safety System

An optional safety system, which will deactivate the main control valve as described in solenoid safety system, will also activate a second solenoid valve to drain excessively heated water from the heater. The controller is designed to permit different set points for the valve closure and draining.

Double Wall Brazed Plate or Plate and Frame Heat Exchanger

Double wall brazed plate or plate and frame heat exchangers have inner and outer plates with a vented leak path. If either the inner or outer plate fails, no cross contamination of potable water is possible and a visible indication of the leak will show.

Advantages of CEMLINE® Vertical Packaged Storage Boiler Water Fired Plate Heat Exchanger Water Heaters

Cemline Vertical Packaged Storage Boiler Water Fired Plate Heat Exchanger Water Heater (SPH) is a perfect solution for domestic water heating systems using hydronic boilers including cast iron, copper tube, water tube, or specialty high efficiency condensing boilers. The SPH heat exchanger allows high efficiency condensing boilers to operate more efficiently since the SPH heat exchanger can return the boiler water to the hydronic boiler at lower temperatures than the traditional u-bend heat exchanger. The boiler water can be returned to the boiler as low as 90°F from the SPH water heater.

The SPH heat exchanger has a high heat transfer rate allowing for maximum heat transfer between the boiler water and the domestic water. As the heat is transferred from the boiler water to the domestic water, the boiler water can experience large temperature drops through the heat exchanger using less boiler water without experiencing laminar flow on the boiler water side of the heat exchanger. The heat exchanger can even allow for temperature crosses between the boiler water outlet and the domestic water outlet temperature, meaning the domestic water outlet temperature can be greater than the returned boiler water temperature.

This heater can be used in many hydronic heating style applications including those systems using low temperature boiler water. The SPH heater can also be used in condensate systems by recovering heat from the condensate to produce hot water.

Cemline Vertical Packaged Storage Boiler Water Fired Plate Heat Exchanger Water Heaters (SPH) are completely packaged and ready for use. The tank allows for storage of hot water and all components are sized, mounted and piped prior to shipment. The heaters come complete and require only connection to services.

Cemline Corporation © Storage Plate Water Heaters are available with Cement Lined STONESTEEL© or 316-L stainless steel vessel in sizes 60, 120, 200, 300, 500, and 680 gallon capacity. The time tested STONESTEEL lining is a unique formulation of hydraulic cement that is durable, reliable, trouble-free lining know for hot water storage. Optionally, the 316-L stainless steel is corrosion resistant and with solid 316-L stainless steel vessel no lining is required.

The Cemline SPH comes factory standard with a either a 2 or 3-way electronically operated boiler water control valve. The 3-way electronically operated control valve allows for close temperature control of the water heater by modulating flow of the boiler water through the heat exchanger. The 1000:1 turn down ratio of the control valve allows for accurate control of these water heaters.
