How One Northeast OEM Relies on Air Cooled Heat Rejection for Their CHP Systems

In the Northeast, where winters are long and energy costs run high, Combined Heat and Power (CHP) systems are becoming a go-to solution for efficiency. One of our OEM partners, based right here in New England, has built its reputation on delivering CHP packages that not only cut utility bills but also provide reliable backup power. At the heart of their design is a cooling system built around DMI Coolers.

Why Cooling Matters in CHP

A CHP system works double duty: it generates electricity and captures the waste heat to provide hot water or heating for the facility. This efficiency depends on one simple fact, the engine driving the system can’t run hot. If it overheats, performance drops, efficiency suffers, and uptime is at risk.

That’s why our customer turned to BA Associates and DMI. These units are designed for high thermal loads, ensuring that their CHP packages can run 24/7, even in demanding industrial environments or remote campuses.

What the OEM Likes About Our Coolers

• Reliability Under Load
  Their CHP units often run near full capacity, especially during winter peaks. The radiators provide steady heat rejection, keeping engines in the safe operating zone.

• Flexible Mounting & Compact Design
  With many installations in tight mechanical rooms or rooftop enclosures, these radiators give the OEM multiple mounting options. This style, in particular, provides extra versatility when airflow or space is a challenge.

• Ease of Service
  The OEM’s technicians appreciate the straightforward maintenance instructions, , bearing lubrication, and core cleaning are all simplified. Less downtime means happier end users.

• Built for the Northeast
  From freezing winters to hot, humid summers, these radiators have proven they can take on the region’s wide temperature swings. Paired with proper glycol mixes and surge tank designs, the systems stay online year-round.

Real-World Results

One recent installation was at a large manufacturing facility in Massachusetts. The CHP package delivered by our OEM partner cut the plant’s utility costs by nearly 30%. Operators reported that the radiator system required minimal adjustment after startup and has been running smoothly since. The reliability of the DMI cooler gave the plant confidence that their investment would pay back quickly.

We’ve seen  first hand how these coolers deliver in CHP, backup power, and other industrial applications. For OEMs, the combination of durability, flexibility, and service support makes the DMI-style radiators a smart choice when reliability is critical.
