The Busiest Part of the Range
The busiest part of the range. Most commercial hydronic, domestic hot water and light process duty lands here, and so does the most widely stocked frame SWEP makes.
- Most commercial hydronic, domestic hot water and light process duty lands in this band, and so does the B25T - the most widely stocked frame SWEP makes.
- Five frames share the 526 x 119 mm envelope: B25T, B28, B80, B85 and B86 differ in channels and plate ceilings, not in the space they occupy.
- The B80 plate is also the plate behind the F80, P80 and V80 evaporators - the same envelope with a refrigerant distributor fitted at the inlet.
- The B16 carries All-Stainless construction into this band: stainless plates and stainless braze, with no copper anywhere in the wetted path.
- Asymmetric channels on the B26 give refrigerant duty a tight side and the water circuit an open one, in a single pack.
- The B10T's 140 plates in a 289 mm envelope make it the heat recovery frame - tight approaches without moving up a size class.
Choosing Within the Band
Several frames in this middle band overlap on flow, so capacity will not pick between them. Plate pattern, channel volume and the materials in the pack will: an H plate buys heat transfer at the cost of pressure drop, an L plate does the reverse, and the material code decides which fluids the unit can carry.
Do not size to the maximum flow figure - the ports set it, and a working duty normally sits below it. Before moving up a frame, see what more plates on the smaller one would do; the longer pack usually closes the approach temperture and takes less pump head. A duty close to the bottom or top of the band should be run against the neighboring band as well. Give us flows, temperatures and fluids, and the answer names the frame, the number of plates and the pressure class.
