15-6	Heat Generation/Refrigeration/Heat Transfer

A.	Heating Coils

1.	Water is the preferred media for heating coils. Steam or electric heating coils must be discussed with Capital Projects (CP).
2.	Provide hot water heating coils with copper tubing and copper or aluminum fins.
3.	If steam is selected, provide distributing type coils. Take particular care with the piping, trap and control installation details to prevent flooding of the coils with condensate.
4.	Heating coils shall have a maximum of 12 fins per inch. Use of this spacing reduces early coating with airborne dust, eventual plugging and facilitates cleaning when necessary.
