Vertical Packaged Storage Plate Water Heaters

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 SSH water heaters are 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 SSH water heater with a 316-L stainless steel vessel will give the customer many years of service without concern of corrosion or tank failure.

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.

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.

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.

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.

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

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).

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

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.

CEMLINE manufactures a complete line of boiler water, steam, and high temperature hot water heating coils, which are constructed of copper or copper nickel or stainless steel tubing. The tube sheets for these coils are copper lined, and units provided with circulating pumps are designed with a copper wrapper surrounding the coil to provide an efficient means of providing the best heat transfer from the coil to the water to be heated. Recovery systems are quickly and efficiently sized to handle specific load requirements to meet any need.

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.

Standard 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.

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 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.

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.

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 loss or loss of building power, the limit control closes the electric power to the controller which closes the 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.

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.

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 coils have inner and outer tubes with a vented leak path. If either the inner or outer tube fails, no cross contamination of potable water is possible and a visible indication of the leak will show. Double wall coils are only available in 3/4″ OD tubing.

PID Control Signal used to modulate an electronic control valve or to control I-P transducer modulating an air operated control valve. The PID controller allows for precise pressure control of the unfired steam generator.

The STEAM-TROL® features an easy to read and operate LCD touch screen display. The STEAM-TROLdisplay indicates pressure set point, operating pressure, PID voltage output, and level control output. The STEAM-TROL® touch screen display has an easy to navigate menu system for adjusting the settings of the unfired steam generator.

Allows for local on-off and is convenient for service in the unlikely event service is required.

The alarm horn will sound and fault LED will light on high pressure, low water, or low pressure. The STEAM-TROL® also features an alarm silence relay which will silence the alarm but not the fault light when the generator is being serviced. When the fault is cleared, both the alarm and fault light will automatically reset.

If the timed blowdown option is selected, the interval and duration of blow down can easily be selected in the STEAM-TROL®.

The STEAM-TROL® operates in conjunction with the level control to signal the feedwater solenoid or feedwater pump to maintain the correct water level in the unfired steam generator.

The STEAM-TROL® operates in conjunction with the level control to signal the to a modulating feedwater valve to maintain the correct water level in the unfired steam generator.

The STEAM-TROL features an easy to read LCD digital readout of the operating pressure.

In the event of high pressure the STEAM-TROL® will close the source steam or HTHW supply valve and sound an alarm.

If activated, the STEAM-TROL® will sound an alarm if a low pressure condition occurs.

The STEAM-TROL® is designed for the user to tell at a glance how the system is operating. The built in LED displays make troubleshooting simple.

Built-in Remote Pressure Setting Building Automation System can remotely set the operating pressure using a 4-20 mA signal.
