Precision Boilers
PCW Electric
50 MBH to 1,500 MBH (1.5 BHP to 44 BHP) @ 99.5% efficiency Developed specifically to fit through a 30” door, the standard PCW’s compact footprint can fit where a fuel-fired boiler cannot. When extra options require a larger cabinet, Precision can customize the assembly to supply the boiler in a ‘knock-down’ condition to preserve the design advantages that make the PCW ideal for retrofits, or where venting a fuel fired boiler is not an option.
HW Electric
1,638 MBH to 8,735 MBH (48 BHP to 260 BHP) @ 99.5% efficiency Nearly identical in design and operation to the PCW, but in a larger footprint to deliver higher heating capacity utilizing a horizontal vessel configuration. Like the PCW, standard models can be customized to meet unique installation and control requirements. It can be installed where venting a fuel-fired boiler is not an option. The HW can be configured to communicate with any building management system.
FPH Vertical Firetube
330 MBH to 4,100 MBH (9.5 BHP to 120 BHP) @ up to 86% efficiency Traditional vertically configured fire-tube design with better overall efficiency due to under-fired power burner. In addition to the simplicity of the 4-piece design, the FPH includes many advantages over other vertical configured boilers. For example, its larger water volume results in both a low pressure drop thru the unit and reduced cycling, to improve overall efficiency.
FTH Flexible Watertube
860 MBH to 17,220 MBH (25 BHP to 500 BHP) up to 86% efficiency Flex-tube forced draft design offers high fuel-to-output efficiency in a compact, maintenance-friendly design that harnesses natural heat convection to ensure consistent internal heat distribution and complete internal water circulation. Noted for their small footprint compared to a horizontal fire-tube, the FTH accommodates up to 150oF temperature differences from the supply and return, and offers virtually instantaneous hot water. The FTH can be configured to communicate with any building management system. Other available options include construction under ASME Section I/VIII for high temperature hot water applications.
ST Electric
100 PPH to 10,000 PPH (10 BHP to 300 BHP) @ 99.5% efficiency Despite its compact footprint, the Model ST’s large steam chest delivers high quality, dry steam with minimum carryover. Fuel-oil or propane boiler retrofits are simpler with a Precision Model ST that requires no vent stack or combustion air louvers and can be supplied in a ‘knock-down’ condition to fit through narrow entries to the old boiler room. The standard ST models can be customized with a variety of factory installed options or configured to connect with field mounted interfaces, giving you exceptional flexibility in design and specification. Adding an SCR creates a boiler with 100:1 turndown to […]
FPS Vertical Firetube
330 PPH to 3,440 PPH (9.5 BHP to 100 BHP) @ up to 83% efficiency Raditional vertically configured fire-tube design with better over-all efficiency due to a bottom-fired power burner. In addition to the simplicity of the 4-piece design, the FPS includes many advantages over other vertically configured boilers, including: large water volume and steam chest that reduces cycling, and an internal feedwater pre-heater to improve overall efficiency and reduce the risk of thermal shock.
FTS Flexible Watertube
863 PPH to 17,255 PPH (25 BHP to 500 BHP) up to 85% efficiency Flex-tube forced draft design offers high fuel-to-output efficiency in a compact, maintenance-friendly design that harnesses natural heat convection to ensure consistent internal heat distribution and complete internal feedwater circulation. The upper steaming chamber is connected to the lower feedwater return vessel via individual serpentine configured carbon steel tubes, to form a 5-pass heat transfer area of 5 sq. ft. per BHP. Separate down-comers connect the upper and lower vessels outside the boiler cabinet to optimize natural circulation and heat transfer.
Skid Package Steam Systems
The most customized solution available, our ‘boiler room on a skid’. This complete steam generating system is custom designed by Precision’s engineering team: pre-piped and pre-wired with controls on a common base, fully functioning and factory tested. The skid packaged steam system simplifies procurement with one-source equipment purchasing, saves time and increases efficiency by reducing uncertainty and potential delays. With Precision skid packs on the job, there’s no need to hire a third-party engineer, coordinate multiple vendor production schedules, or schedule multiple deliveries, with the associated crane rental costs.
STH High Pressure Electric Steam
100 PPH to 10,000 PPH (10 BHP to 300 BHP) @ 99.5% efficiency When specification calls for higher pressure process steam (> 200 psi operating), the STH delivers high quality process steam in a compact footprint. Custom models can be supplied in a ‘knock-down’ option to fit narrow entries. Optional SCR control provides near infinite modulation to precisely follow heating load. Requires no vent stack, breeching, or combustion air louvers. The STH is perfect for high pressure process steam installations, and saves time and money, with no need for custom ventilation.
HVJ High Voltage Jet Electrode Boiler
2,700 PPH to 140,000 PPH (80 BHP to 4,200 BHP) @ 99.5% efficiency The HVJ is configured to operate from one of three different 3-phase power supplies: 4160 volt, 6900 volt, and 13.2 KV, and its standard operating pressures range from 100 psi to 400 psi; for higher pressure models consult factory. Particularly well-suited as an auxiliary boiler for power generation facilities and central steam plants, or as a pony boiler for industrial process expansions or additions. The HVJ provides virtually instant steam when needed, ramping up from standby to full output in minutes or even seconds, and can dramatically reduce energy costs using off-peak power. It is commonly used […]
ISH Instantaneous Superheater
Provides super-heated steam for high temperature process or power generation applications. ISH electric instantaneous superheaters are custom designed to fit nearly any steam re-heat requirement. Standard SCR control provides near infinite modulation to maintain steam set-point temperature. Requires no vent stack, breeching, or combustion air louvers.
CF Boiler Feedwater Systems
20 gallons to 950 gallons, support 15 BHP to 720 BHP size boilers Non-code condensate receiver tanks are recommended when there is a high rate of condensate return and minimal make-up water is required. Our CF systems are designed to receive condensate and prepare it for return to the boiler. They can also be paired with a DA to accommodate condensate surges that would otherwise be lost through the DA’s overflow drain. Precision CF systems are custom designed to include the appropriate pump and control packages that best fit the application requirements.
SP-DA
Spray deaeration-5,000 PPH to 300,000 PPH Storage-140 nominal gallons to 6,000 nominal gallons of feedwater to overflow Deaerators (DAs) are recommended when the steam system requires significant volumes of make-up water that must be treated to remove free oxygen and carbon dioxide from boiler feedwater. Precision’s Spray-Type DA relies on internal spray valves, a vent condenser, and fresh steam to create conditions by which the make-up water releases the O2 and CO2 naturally, reducing the consumption of costly oxygen scavenging chemicals otherwise required to prevent corrosion leading to premature steam system failure.
TR-DA
Tray deaeration-5,000 PPH to 500,000 PPH Storage-110 gallons to 10,000 gallons of feedwater to overflow Deaerators (DAs) are recommended when the steam system requires significant volumes of make-up water that must be treated to remove free oxygen and carbon dioxide from boiler feedwater. Precision’s Tray-Type DA is the best choice for large stream flows where limited condensate return creates a large demand for makeup water. The Tray Type DA relies on internal spray valves, a cascading series of trays, a vent condenser, and fresh steam to create conditions for large flows of make-up water to release the O2 and CO2 naturally. Investing in a Tray-DA reduces dramatically the consumption of […]
Chemical Feed
Precision chem feed packages offer an extra measure of protection against corrosion and scaling in your steam system, to maintain peak efficiency and improve the performance of your entire boiler package. When treatment chemicals are required to protect your boiler system, our chem feed packages save time and money with complete packages and easy installation.
Surge Tanks
20 gallons to 950 gallons, support 15 BHP to 720 BHP size boilers Usually paired with a deaerator to provide additional condensate storage capacity when operating conditions cause a sudden surge of condensate return that would otherwise overwhelm the storage capacity of the DA and be lost through the overflow to the drain. Our Surge Tanks are essentially CF packages without the preheater. Precision surge tanks are pre-mounted, piped, and wired condensate receiving storage tanks, with a float activated make-up water valve that adds fresh water to replace condensate lost through the steam loop to maintain sufficient water level inside the tank.
BD Blowdown Tank
30 gallons to 1,200 gallons The Precision standard, used where there is ample space for a large tank to collect and hold boiler blowdown, allowing the effluent time to cool below 140oF before releasing it to the facility drain. The portion of blowdown that flashes to steam vents to atmosphere or can be recovered to preheat boiler feedwater.
BDS Blowdown Separator
10 gallons to 50 gallons, suitable for boiler operating pressure up to 800 psi A blowdown separator is the best choice when space limitations preclude using a large tank to collect and hold the effluent while it cools to an acceptable drain temperature. The blowdown separator accepts boiler blowdown, vents the portion that flashes to steam, but does not store the effluent until it cools. Instead, a temperature controlled mixing valve mounted in the tank’s discharge piping adds cold make-up water to cool the effluent as it immediately discharges to the drain.
HWS Electric Commercial Water Heater
125 gallons to 5,000 gallons When you need a lot of domestic hot water, quickly and reliably. The HWS commercial volume storage water heater is designed for industrial, commercial and institutional users who require large quantities of service water at preset temperatures. Two different NSF-61 compliant lining options are available: our standard PS lining is a two-part epoxy that delivers service performance that is superior to glass; the aluminum silica cement is recommended for water temperatures above 190oF and offers the longest service life. Standard models are configured with a vertical vessel; horizontal models can be ordered.
FPW Vertical Firetube Water Heater
100 gallons to 1,500 nominal gallons Conventional fire-tube construction in a water heater design. The FPW offers 84% efficiency with reduced burner cycling, proven fire-tube reliability, simple installation, and easy access for servicing with its simple 4-pc. design.
PHWS Indirect Fired Water Heater
125 gallons to 4,000 gallons of actual capacity; contact us for larger options available The PHWS uses existing thermal energy sources to heat domestic hot water.
