Nine Frames for Plant-Scale Duty
Commercial plant scale - chiller circuits, heat recovery and the larger domestic hot water stations, including the copper-free frames for ammonia and pure water.
- From 104 to 192 GPM, this band covers packaged chillers, mid-size process skids and the district substations that most buildings actually need.
- The B45, B120T and B200T share one 525 x 243 mm footprint - same mounting, different pass options and plate generations.
- The B120T is the stock habit of the band: 304 plates for ordinary water, with counts of 50, 60 and 70 commonly held.
- The B185 is the largest transcritical CO2 frame, asymmetric and rated past 64 bar from the brazed pack alone.
- The FI190 answers the low-GWP refrigerants - R32, R454B and R290 - where every liter of hold-up volume counts against a charge limit.
- All-Stainless arrives at plant scale with the B221 and B222: copper-free construction past 100 GPM.
Choosing Within the Band
At these flows the pump matters as much as the exchanger. Two frames in the band may both pass the flow, yet one does it at a pressure drop the pump cannot spare. So compare them on channel volume and on the highest plate count each accepts, and check the construction against the fluid - on larger frames the material code can read NSC, which is 316 channel plates with 304 cover plates.
The maximum flow published for a frame marks where the ports run out; it says nothing about the thermal duty. Adding plates to a mid-size frame is often the cheaper route to a close approach temperature than jumping to the next frame, and it lowers the pumping cost too. If the duty falls near either end of the band, look at the adjacent band as well. With the duty and the fluids in hand we return the frame, the plate count and the class letter.
