Six Frames Under 500 mm Tall
The smallest frames in the SWEP range - single-digit to eighteen gallons a minute, in packages under 500 mm tall. Appliance duty, small hydronic loops, and the three sizes rated for transcritical CO2.
- Six frames from 193 to 468 mm tall cover single-digit to 17.61 GPM duty - appliance hydronics, instantaneous hot water and small process loops.
- The B4 and B18 carry SWEP's transcritical CO2 ratings, with the U class reaching 140 bar from the brazed pack alone.
- The B8T is the copper-free option at this size: nickel brazed for ammonia, deionized water and streams too hot for a copper filler.
- The E6T was designed around wall-hung boiler hot water and prices accordingly - specify it for what it was built for and it is hard to beat.
- Four-pass builds are common on the B5T and B15T, recovering channel velocity when the flow alone would leave the plate underused.
- Particle ceilings run 0.4 to 1 mm across the band, so the strainer is part of the specification on every one of these frames.
Choosing Within the Band
These are the compact frames, and the choice between them is mostly a question of port size and how many plates each will take. A small frame with a long plate pack and a slightly larger frame with a short one can carry the same duty; they differ in pressure drop, in internal volume, and in where the connections land on the existing piping.
Read the published maximum flow as the limit of the ports, not as a design point. On a new duty, give the plate count room before stepping up a frame, since extra plates tighten the approach temperture and ease the pumping together. Units this small tend to get hung on their own pipework - support the lines so the connections carry no load. Tell us the duty and both fluids and we will come back with the frame, how many plates, and the class.
