Brazed Plate Heater Cemline Packaged Brazed Plate Boiler Water Fired Water Heater

Advantages of Cemline® Packaged Brazed Plate Boiler Water Fired Water Heater
Cemline Packaged Brazed Plate Boiler Water Fired Water Heaters (BPH) 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 heat exchanger allows these boilers to operate more efficiently since the BPH 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 water heater.

Cemline Packaged Brazed Plate Boiler Water Fired Water Heaters (BPH) are completely packaged and ready for use. The BPH 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 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 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.

By taking large boiler water temperature drops less boiler water is used to heat domestic hot water. This reduces the BTU load on the boiler by the water heater, which ultimately reduces the boiler size required for the hot domestic water load. 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 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 1000:1 turn down ratio of the control valve allows for accurate control of these water heaters.

AC Series
Cemline Condensate After Coolers / Leg Assembly are designed to cool condensate or hot water. The after cooler assembly mixes hot water with cold water resulting in liquid temperatures acceptable for municipal sewage and per the local code. This packaged after cooler is perfect to be installed after a flash tank, blow down tank, or condensate receiver as condensate should be flashed before entering the condensate after cooler.

This unit is versatile as it can be supplied to be mounted either in a horizontal or vertical position.

The Condensate After Cooler is supplied with check valve, cooling valve, and thermometer. The self-acting thermostatic cooling valve can be field adjusted to the desired set point between 77 and 150 oF. The valve opens as temperature increases on the bulb.

Standard Items:
After Cooler
Check Valve
Cooling Valve (1/2", ¾", and 1")
Thermometer

System Efficiency Buffer Tanks (SEB series)
CEMLINE® Primary/Secondary Buffer Tank, Air Separator

• Improves Efficiency of the Heating System
• Eliminates the Need for an Air Separator
• Primary/Secondary Hydraulic Separator

Cemline primary/secondary buffer tanks improve system efficiency by preventing the problem of short cycling boiler(s).
Low water content boilers operating at low loads will short cycle leading to sooting, premature component failure, and nuisance shut downs. If the boiler is allowed to fire for a minimum of several minutes the full efficiency of the boiler can be achieved preventing sooting, premature component failure, and nuisance shut downs.
Boiler systems are sized to heat the building on the coldest days. When the outside temperature is above minimum outside design conditions the boiler may only require a short period of firing to warm the building causing short cycling of the boiler. Installing a Primary/Secondary buffer tank prevents this short cycling. Many boiler manufactures do not recommend firing the boiler(s) more than 6 cycles per hour.

Cemline primary/secondary buffer tanks remove air from the heating system, thus eliminating a separate air separator.
Boiler systems require a low velocity area in the system to allow entrained air to be separated from the boiler water. A Primary/Secondary Buffer tank will have extremely low velocity and is used as the air separator, thus eliminating the need for a separate air separator.

Cemline primary/secondary buffer tanks act as a hydraulic separator by separating the primary and secondary sides of the boiler system.
The primary/secondary hydraulic separator allows for variable volume systems to operate with the modern boiler as instructed in ASHRAE 90.1.

Cemline Primary/Secondary buffer tanks come complete with insulated jackets [R-12.5] with Velcro closures for simple field installation.

Cemline Primary/Secondary buffer tanks have a well to accept Building automation system or customer supplied temperature sensors. As an option a factory supplied digital electronic thermostat can be supplied to cycle the boilers on call for heat. This digital electronic thermostat has a LCD temperature display and can be easily field programmed for a minimum of 2 oF and maximum of 30 oF temperature differences.

The SEBs are vertical tanks, which come in 120, 200, 300, and 500-gallon capacities. The standard options on an SEB include ASME Pressure vessel (125 psi working pressure @400 F), an air vent, a field installed insulated jacket, and thermometer. Optional equipment is a digital electronic programmable thermostat.
