SWEP V200T

SWEP publishes 9.45 kg plus 0.45 kg per plate (20.84 lb plus 0.992 lb per plate). The largest configuration on file, 140 plates, comes to about 72 kg (160 lb); the 250-plate maximum to about 122 kg (269 lb). Both are dry weights.

Support the unit under the plate pack on a bracket or base. The 2 in water lines and the large suction line should each have their own hanger within a short distance of the unit, so the connections see neither the pipe weight nor the vibration.

The published channel volume is 0.241/0.241 - per channel, the same on each side. Multiply by the number of channels on a side, close to half the plate count, for the hold-up.

It matters most when the plate count changes. Going from a 60-plate unit to a 110-plate unit nearly doubles the refrigerant held in the evaporator, which changes the charge and can matter where a refrigerant charge limit applies to the equipment. Keep the original plate count unless the duty has changed.

Start with 525 x 243 mm (20.67 x 9.57 in) and port centres of 448.5 x 163.5 mm. Those confirm the frame and that the lines will meet the ports.

Next, the refrigerant connections. The catalogued V200T units come two ways: a 28U inlet with a 54.3&60 combo outlet, or a 35.1 inlet with a 66.8 outlet, both with 2x2" water connections. Measure the suction connection on the old unit to tell which you have. A 28U takes 1 1/8 in and 28.75 mm pipe.

Last, depth. It grows with plate count, and the configurations on file span 40 to 140 plates.

By the nameplate, not by size - all of them are 525 x 243 mm. The V200T, F200T and P200T are single evaporators at 192.41 GPM; the F200T and P200T are listed with 304 plates, while the V200T is published with 316 channel plates and 304 covers. The B200T is the base model, in 316/316L.

The DV200 and DP200 are True Dual evaporators and the DB200 a True Dual condenser, at 118.88 GPM. They belong to chillers and heat pumps built around a True Dual exchanger and do not replace a V200T.

The listed approvals are PED, UL and KHK. For an installer the practical point is that the approval and the rating stamped on the individual unit are what an inspector checks, so the replacement has to carry the same marks as the unit the equipment was certified with.

If the job needs something beyond those three - an ASME stamp or a CRN, for example - state it with the quote request and we will confirm what can be supplied. Do not assume it from the model name. Approvals and Certifications explains each mark.

It is built to evaporate refrigerant against water or glycol in chillers and heat pumps, and to serve as an economizer.

It is the wrong choice in four cases. For plain liquid-to-liquid duty, an evaporator model buys nothing over the B200T. For ammonia or deionized water, the copper braze rules it out. For chloride-bearing water, 316 plates pit. And for a machine built around a True Dual exchanger, the DV200 or DP200 is the unit that fits. See Evaporators for evaporator selection.

These models are catalogued alongside the V200T. Each has its own page with its dimensions, materials and part numbers.
