Boilers + water heating
Condensing boilers
KN Series
Cast iron boilers with packaged systems and HeatNet controls.
Steam / hot water
Smith Cast Iron Boilers
Sectional cast iron boilers for steam and hot water applications.
Steam / hot water · Columbia legacy
Pottstown Engineered Products
Rugged firetube and vertical tubeless boilers for steam and hot-water applications.
Industrial boilers
PowerMaster
Industrial firetube boilers for hot water and high pressure steam.
Electric boilers
Reimers Electra Steam
Packaged electric steam and hot water solutions.
Steam generation
Thermogenics
Up to 600 horsepower Ohio Specials. Industrial coiled watertube steam generators for demanding steam applications.
02 /
Burners + controls
Power burners
Webster Combustion
Burners for boilers, ovens, and air handling applications; new equipment and retrofits.
Total boiler room solution
Siemens Combustion Controls
From burner to boiler to deaerator: combustion, sequencing, water level, and feedwater controls working together across the room.
Boiler plant controls
Heat-Timer
Let the boilers follow the load. Outdoor reset and multi-boiler sequencing match heat to demand, with optional remote monitoring.
03 /
Venting + chimney automation
Stainless steel venting
Enervex PowerStack
One vent family for a complicated room. Listed for Category I–IV appliances, with a welded corrosion-resistant 316L-PCM liner and single- or double-wall options.
Venting systems
Security Chimneys
Chimney, vent, grease duct, and generator exhaust systems.
Chimney automation
Enervex
Mechanical draft, modulating combustion air, and plume management.
04 /
Mechanical room accessories
Pumping / feed
Shipco
Condensate return and boiler feed equipment, surge tanks, and deaerators.
Steam / heat exchange
ThermaFlo
Steam-fired water heating, clean steam, condensate recovery, and heat transfer.
Air separation
Spirotherm
Engineered air, dirt, and magnetic separation for hydronic systems.
ASME expansion tanks
ELBI of America
Floor-standing HTL hydronic expansion tanks with replaceable bladders absorb heated-water expansion and help control system pressure. Storage vessels and related tank equipment complete the line.
Boiler return protection
Fluid Power Energy
Let the system reset lower without chilling the boiler. A self-acting wax thermostat routes flow to help protect the heat exchanger’s specified return minimum—often 130–140°F—with no wiring or motor.
Feed / blowdown
PEP · Pottstown
Horizontal and vertical feed systems automate makeup water and boiler feeding; blowdown separators cool hot discharge and help remove efficiency-robbing solids.
05 /
Heat recovery
Boiler economizers
HeatSponge
Put exhaust heat back to work. Serviceable economizers preheat boiler feedwater; two-stage systems can also heat makeup or process water.
Integrated heat recovery
Enervex
Capture heat leaving the stack. VHX economizers combine flue-gas heat exchange with a modulating bypass, and can serve single or multiple boilers.
06 /
Specialty applications
Radiant / snowmelt
Roth North America
Radiant and snowmelt tubing, manifolds, panels, and controls.
Makeup air
Rapid Engineering
Industrial makeup air, building pressurization, heat recovery, and exhaust.
Kitchen / bath / dryer exhaust
ENERVEX
Demand-controlled exhaust systems for multi-story kitchens, bathrooms, and clothes dryers modulate fan speed with building load.
