ADVANTAGES

Cemline Packaged Plate Boiler Water Fired Water Heaters are a perfect choice for domestic water heating systems using hydronic boilers including cast iron, copper tube, water tube, or specialty high efficiency boilers. The BPH uses a brazed plate heat exchanger for smaller loads, while the PFH uses a plate & frame heat exchanger for larger loads.  The BPH/PFH heat exchanger allows these boilers to operate more efficiently since the BPH/PFH 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 BPH/PFH water heater.

Cemline Packaged Plate Water Heaters (BPH/PFH) are completely packaged and ready for use. The BPH/PFH can be used in conjunction with an existing tank or used as an instantaneous water heater. The heaters come complete and require only connection to services.

The BPH/PFH 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. The BPH/PFH can achieve larger temperature drops through the heat exchanger requiring less gallons per minute of boiler water than a traditional U-bend heat exchanger that is performing a 20°F delta T on the boiler water side. The large temperature drops occur without 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.

The boiler can be run at lower temperatures with the BPH/PFH's ability to perform temperature crosses and to take large delta T's as a lower boiler water temperature can be used to make domestic hot water.

Cemline Corporation Brazed Plate Water Heaters are available with a storage tank either a cement lined STONESTEEL® or 316-L stainless steel vessel in sizes 60, 120, 200, 300, 500, and 680 gallon capacity. See Cemline SPH brochure for more details.

The Cemline BPH/PFH comes factory standard with a 2-way electronically operated control valve. The 2-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 BPH/PFH can achieve +/-2°F with a steady state flow and +/- 4°F under normal operating conditions.  The 1000:1 turn down ratio of the control valve allows for accurate control of these water heaters.

The Cemline BPH/PFH can be used for a variety of heat recovery systems or in hot water or chilled water systems.

WARNING: BPH/PFH water heaters are not recommended for water with hardness over 140 parts per million. If water hardness exceeds 140 ppm, either put a water softener in the system or use Cemline SEH, SSH, or SWH series water heaters

STANDARD EQUIPMENT

Plate heat exchangers are extremely efficient allowing for close or cross temperature approaches between the boiler water and heated water. Cemline offers either a single wall or double walled brazed plate style heat exchanger.

CEMLINE packaged units are neatly and attractively packaged on a 16 gauge steel frame. The frame protects the unit, and is professionally painted with superior quality enamel to allow the added importance of an easy to maintain surface.
 

CEMLINE plate heaters are mounted on structural 4”channel support skids designed as a permanent base. This skid is pre-engineered to allow correct support for the heater.
 

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 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 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.
 

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.
 

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
 

CEMLINE provides clean out ports on the inlet and outlet piping of the BPH/PFH allowing for cleaning of the plate heat exchanger.
 

CEMLINE plate heaters are supplied with a boiler water strainer on the boiler water inlet. Strainers are "Y" type with blow down connection and easily removable stainless steel strainer screen.
 

CEMLINE plate heaters are supplied with a domestic water strainer on the domestic water inlet. Strainers are "Y" type with blow down connection and easily removable stainless steel strainer screen.
 

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

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.
 

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 temperature control of the water heater.
 

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 temperature or secondary high temperature. The CEM-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.
 

Only one 120 VAC connection required to the unit, integral circulation pump is pre-wired to the control panel.
 

The CEM-TROL^® features an easy to read LED digital readout of the operating temperature.
 

In the event of high temperature, the CEM-TROL^® will close the source steam or HTHW supply valve and sound an alarm.
 

In the event of the secondary high temperature set point has been exceeded, the CEM-TROL^® will open an optional water solenoid to dump over heated water down the drain.
 

Building Automation System can remotely set the operating temperature using a 4-20 mA signal.
 

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