Alfa Laval Spiral Heat Exchanger. Model: 1-HC. S/N: 18058. Nat'l Bd: 13696. MAWP: 150 psi @ -20 to 625 °F. Surface: 60 sq. ft. Head material: SA-516-70 carbon steel. Head thickness: 1.35 in. Shell material: SA-516-70 carbon steel. Shell thickness: 0.1875 in. The spiral heat exchanger consists of a strip of metal wound around a central core to form two concentric spiral channels - one for each of the fluids between which heat is to be transferred. Normally intended for liquid/liquid services or condensing smaller rates of vapor. Flows are normally counter-current. Inlets: (1) 2 in. dia. cold-side flanged port, (1) 6 in. dia. hot-side flanged port. Outlets: (1) 2 in. dia. cold-side flanged port, (1) 6 in. dia. hot-side flanged port. Overall dimensions: 40 in. L x 32 in. W x 32 in. H.
(4) Cherry-Burrell Spiratherm Coiled Tube Heat Exchangers. Spiral tube outer diameter: 5 in. Spiral tube inner diameter: 4 in. Shaft dimensions: 64 in. L x 3 in. dia. Inlets: (1) 1 in. dia. female ferrule for spiral tube, (1) 1-1/4 in. dia. FPT for refrigerant, (1) 1-1/2 in. dia. FPT. Outlets: (1) 1-1/4 in. dia. FPT for refrigerant, (1) 1 in. dia. female ferrule for spiral tube. Coiled tube heat exchangers have a single tube coiled inside a shell. Designed to operate at very high pressures with high heat transfer rates allows products to flow through the tube at high velocities which reduces fouling and increases run times. Typical applications include viscous products such as: BBQ sauce, slurries and puddings. Overall dimensions: 7-1/2 in. dia. x 6ft. 5 in. L.
