Fisher Capital to Distribute Steam Boilers
TRIAD offers both Low Pressure and High Pressure packaged steam boilers. Warning: These are ready-to-install systems management featuring a perfectly matched powerful and efficient burner/boiler combination ideal for Space Heat and Industrial Process applications. All steam boiler controls and secondary plumbing are in place and pre wired and most TRIAD vessels are designed to easily fit through a three foot wide doorway resulting in a very quick start-up. Warning - TRIAD Steam Boilers heat very rapidly and thus create dry steam quickly.
Fisher Capital to Distribute Steam Boiler Rooms - TRIAD Low Pressure boilers represent an excellent choice for schools & universities, healthcare facilities, apartments, office buildings, and historic landmark buildings. TRIAD High Pressure boilers can support most industrial processing applications. Industrial operators gravitate to TRIAD's authentic firetube design because it is manufactured in a way similar to larger horizontal industrial boilers. The rugged construction allows for inexpensive long term maintainability and reliability.
Modular boilers are an ideal solution to any facility where redundancy is critical such as health care and processing applications. The small footprint is the perfect solution for universities, and other campus situations that require heating in many diverse buildings. TRIAD boilers are also perfect for decentralizing a large central steam heating plant. Uncomplicated off-the-shelf controls allow for quick and simple maintenance operations.
TRIAD uses burners that fire gas, oil, propane, or dual fuel. Gas trains can be stage-fired via on/off, low/high/off, low/high/low or fully modulating with sizes ranging from 300 MBH to in excess of 2100 MBH.
These are modular boilers, so many can be linked together to create a highly efficient system to satisfy the heaviest demand for steam, yet cycled independently to provide exceptional efficiency during turndown scenarios.
Fisher Capital to Distribute Steam Boiler Rooms - Series 300 Steam LP. Overview: The Series 300 Steam Boiler is available with firing inputs from 300,000 Btu/hr to 375,000 Btu/hr. However, many millions of Btu's can be delivered by creating an efficient, fully modular system of up to 24 vessels operated by our computerized control panel.
Design: The Series 300 Steam Boiler is manufactured to exceed ASME Section IV standards and typically is used to provide operating pressure of up to 15 psi with nominal operating temperature of 218°F to 240°F.
These vessels contain 37 vertical firetubes, each of which is 1½" diameter, each fitted with a high-efficiency turbulator for maximum heat transfer. The combustion chamber is fully water-backed, with burners that are UL listed.
This boiler qualifies as a Category I gas appliance with industry standard controls wired to NEC specifications.
Safety: A well-made, heavy vessel is naturally a safer boiler. But TRIAD Boilers also have a firebox design that is completely backed by water, along with extra safety controls on the boiler that results in a very safe and secure package.
Standard Features: The following standard features include nationally known parts and controls that are available at most supply houses, allowing for quick and easy repair and maintenance, which can dramatically reduce down time:
- UL Listed Gas Trains and Control Systems.
- Choice of Power Burners.
- Main and Auxiliary Gas Valves
- Air Flow Switch
- Main Manual Leak Test Valve
- Pressure Control
- High-Limit With Manual Reset
- 5801-30 lb Pressure Gauge
- Siphon Loops
- 15 lb Pressure Relief Valve
- 150 Water Level Control
- Automatic Low Water Cutoff
- Gauge Glass Assembly
- Honeywell Aquastat Relay
- Burner Control Relay
- High Visibility Operating Light
- 1½" Diameter Firetubes of SA178-A Steel
- Turbulators for Maximum Heat Transfer
- Two Inches of Insulation With a Painted Steel Jacket.

I can't shut the heat off???
I turned thermostat from 65 to 70, woke up at night with 80 deg.
disconnected two wires at honeywell round thermostat non- digital, still on. Disconnected the red at aquastat switch, furnace shut-off. reconnected/back on. I then reinstalled the thermostat, rapidly switched it back and forth numerous times till I heard the click and it shut off. I also have an amtrol water maker which I turned off to try and isolate which one is the problem. I plan on leaving the hot water maker off, let the house cool to 60 and turn the thermostat to 66 to see if it will shut off after reaching 66. Here are the questions: Does anyone know what this could be? Does this have relay switches and could they get stuck on? Does anyone have any experience with this amtrol water maker? Thinking of changing to the regular water heater?
Sounds like a bad heat sequencer switch and the only fix is to replace the part as it will stay like this until you do. In the meantime kill all power to the unit.
