Heat, cooling, exhaust
Radiators, exchangers, silencers, and aftertreatment as one package — not a catalog of parts.
Est. 1991 · Greater Philadelphia
Balance of plant,
engineered to the site.
Custom heat transfer, exhaust emission control, cogeneration, and cooling for the world’s premier stationary generators — data centers, hospitals, and mission-critical plants across the U.S.
Permit-ready emissions
SCR, oxidation catalyst, NSCR, and DPF systems sized to the engine and the air permit.
Field-backed engineering
Submittals, 3D design, commissioning, and SCR service from the same office that sold the job.
Boulden Industrial Cooling
Custom coolers, heat exchangers and package solutions.
See packages →Shop-built remote coolers, heat exchangers, and closed-loop packages — framed, piped, and shipped as one unit for stationary generator sites.
Pump skids
Duplex pump packages, piped and controlled.
Shop-built pump skids for closed-loop cooling — dual motors, strainers, gauges, and an HMI panel on a common steel base.

Solutions for distributed power
Heat transfer & cooling
Remote and engine-mounted radiators, charge-air coolers, plate-and-frame and shell-and-tube exchangers, fuel-oil coolers, and closed-loop packages sized to site load.
Emission control
Complete exhaust aftertreatment for diesel and natural-gas engines — SCR, oxidation catalyst, NSCR, DPF, and urea/DEF distribution — engineered to permit and performance.
Exhaust systems
Residential, critical, and hospital-grade silencers, low-profile enclosure units, stainless construction, thimbles, flex, and expansion joints fabricated to spec.
Cogeneration & heat recovery
Hot-water and steam cogen, process heat recovery, load balancing, feedwater economizers, and ASME-code vessels — designed around the thermal loop, not just the engine.
How we work
Forward-thinking sales engineering
Boulden Energy Systems is a manufacturer and manufacturer’s representative. We size balance of plant to site constraints — noise, envelope, heat rejection, and emissions — then coordinate the order through commissioning.
- Site-specific sales engineering
- Balance-of-plant design and sizing
- Full electronic submittals
- AutoCAD and 3D design
- Order tracking through commissioning
- Local East Coast field support
