A pioneer in corrugated fin development HI-F Means High Efficiency A principal factor governing fin heat transfer efficiency is the boundary layer film of air adhering to any fin surface. This boundary layer insulates the fin, severely reducing the rate of heat exchange. The advanced rippled-corrugated HI-F design creates a state of continuous turbulence which effectively reduces the boundary layer formation. The exclusive rippled edge instantly deflects the incoming air to create initial turbulence. A succession of corrugations across the fin depth, in conjunction with the staggered tubes, increases...

Circuiting arrangements Hot water coil circuitings Type 5WB, 5WQ, and 5WH coils are designed to produce high capacity with limited water quantity. High performance is achieved by the increased water velocity obtained from the circuiting of these coil types. Type 5WL and 5WS coils are designed and engineered to meet most applications requiring normal water quantities and normal water pressure drop. Type 5WM and 5WD coils are designed specifically for applications that require high water quantities and low water pressure drop. Hot water (booster) coil circuiting Type 5BB, 5BS and 5BD hot water...

Design features A variety of fin spacings Standard water heating and booster coils are available with 06, 07, 08, 09, 10, 11, 12, 13 or 14 fins per inch. The wide variation in fin spacing permits accurate balancing of coil capacities with the design load. Copper tube headers To provide extended coil life, 5W water heating coils are manufactured from heavy-gauge seamless drawn copper tube. Intruded tube holes provide maximum brazing surface for maximum strength. Copper tubes brazed to copper headers offer a combination of similar materials which eliminates unequal thermal expansion and greatly...

General specifications - 5W and 5B coils (1) Primary surface Round seamless copper tubes on 1-1/2" or 3" centers. Cupro-nickel tubes are recommended for high pressure coils and for applications where water conditions tend to be corrosive. (2) Secondary surface Rippled-corrugated aluminum or copper, dieformed plate type fins. 2A. Fin collars are fully drawn to completely cover the tubes for maximum heat transfer and to provide accurate control of fin spacing. (3) Headers Extra-heavy, seamless copper tubing. Tube holes are intruded to provide maximum brazing surface for added strength. Header end...

Application recommendations 1. Piping should be in accordance with accepted industry standards. 2. When drainable coils are desired, tubes should be installed in a horizontal position. Use a spirit level. If the tubes cannot be installed level, special drain headers are available on request. 3. Connect the water supply to the leaving air side and the water return to the entering air side of the coil. Connecting the supply and/or return in any other manner will result in a reduced performance. 4. Hot water coils are not normally recommended for use with entering air temperatures below 40° F; however,...

Sample coil selection Given: Assuming a 1-row type 5WB coil will meet the requirements, the proper fin series must be determined as follows: 8. Determine heat transfer value, Mt: a. Air Temp. Rise = 36.7 = .237 Ent. Water Temp. - Ent. Air Temp 200 - 45 b. Water Temp. Drop Air Temp.Rise Solution: 1. Determine coil face area: 24 x 72 = 12.0 sq. ft. 144 With values from steps a. and b. above, proceed to Figure 3, page 11, and find Mt = .33 2. Determine coil face velocity: SCFM = 6,000 = 500 FPM 12.0 Face Area Determine heat transfer value, Rft: Rows Deep = Rft x Mt x FPM 100 3. Determine air temperature...

Conversion of air volume to standard air Figure 1. TEMPERATURE CONVERSION FACTOR - FT 1.25 TEMPERATURE CONVERSION FACTOR EXAMPLE: To convert 15,900 CFM of air at 95°F and at 3,000 feet altitude to standard conditions: When the specified air volume (CFM) is given at any temperature other than 70° F or any altitude other than sea level, these charts should be used for correction before using the capacity and pressure drop tables which are based on CFM at standard air conditions. TEMPERATURE CONVERSION FACTOR Where: FT = Temperature Conversion Factor from Figure 1 FA = Altitude Conversion Factor...
