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 Chilled water circuitings 5 standard serpentine circuitings Counterflow water circuits Unique or universal hand of connection Evaporator coil circuitings NOTE: See page 24 for exact number and location of coil connections.

HEADERS - Extra-heavy seamless copper tubing. Tube holes are intruded to provide the maximum brazing surface for added strength. Header end caps are heavygauge, die-formed copper. Cupro-nickel headers and Monel end caps are available for special applications. CONNECTIONS - Unique hand or universal connections can be provided. Connection type must be specified. Water Coil Connections: Steel male pipe supply and return connections. Other materials available on request (red brass connections recommended on type 5W coils when used with non-ferrous piping). Evaporator Coil Connections: Male sweat...

Coil Selection General Considerations The cooling process should always be plotted on a psychrometric chart to be sure that desired psychrometric changes are feasible. When selecting a coil, it should be remembered that if the required leaving wet bulb temperature is attained, the total load is satisfied and vice versa. Also, when the required leaving dry bulb temperature is met, the sensible load requirement is satisfied. A coil must meet both the total and sensible load requirement in order to achieve the conditions desired in the space to be cooled. Normally, the total load capacity is checked...

HI-F5 & E-F5 water cooling coils HI-F5 and E-F5 water cooling coils are designed for use with chilled or well water on comfort cooling, process, dehumidifying and special applications. All water cooling coils have vents and drains to aid drainability. 5W Water Cooling Coils are designed for general purpose cooling. All 5W coils have heavy-gauge seamless drawn copper tube headers with carbon steel connections. This proven header design can lengthen coil life by providing necessary header flexibility to compensate for normal expansion and contraction during operation. Intermediate drain headers...
