SWEP P200T

Refrigerants on one side, and clean water or a glycol solution on the other, are what it is built for. 304 plates with copper braze is the NC construction - ordinary water, lower cost.

The limits follow from the two metals. Ammonia attacks copper. Deionized and ultrapure water leach it. Chlorides pit stainless steel, and the remedy for chloride-bearing water is SMO 254 plates, not 304. Plate and Brazing Materials lists the copper-free and high-alloy constructions.

Not by size. All of the 200T models measure 525 x 243 mm, so the outline only confirms the family. The first letter of the designation is the distinguishing mark, and the trailing T matters too - it marks a plate generation, and a T plate is physically different from a plate without it.

If the letter is gone, look at the connections and at the machine. The P200T is published with solder connections and for evaporator duty, so a unit with threaded water ports or one installed as a condenser is unlikely to be a P200T. The machine's own parts list is the surest source. The Model Number Guide explains the remaining fields.

Published empty weight is 9.45 kg plus 0.45 kg per plate: about 32 kg (70 lb) at 50 plates, 108 kg (239 lb) at 220 plates and 122 kg (269 lb) at the 250-plate maximum.

Yes, it needs support of its own. Solder connections are the weakest place to carry load - copper tube brazed into the ports will hold the unit up for a while and then crack at the joint once compressor vibration works on it. Set the unit on a bracket or shelf under the plate pack, strap it back to the frame, and make sure it is mounted vertically.

The F200T is its closest relative: an evaporator optimized for high performance with long thermal length, also in 304 stainless with copper braze, on the same 525 x 243 mm footprint. The V200T is a further evaporator on that footprint, described as optimized across many refrigerants, with 316 channel plates and 304 cover plates. The three letters identify different models, so none should be exchanged for another without a rating.

The DP200, DV200 and DB200 share the outline but are True Dual models with two refrigerant circuits, and their published maximum flow is about 119 GPM against 192 GPM for the P200T. A single-circuit machine takes the P200T; a two-circuit machine takes a True Dual model.

These models are catalogued alongside the P200T. Each has its own page with its dimensions, materials and part numbers.
