· The Prima-Flo coil features a parallel 5/8-inch tube pattern. The energy efficient Prima-Flo E fin surface is designed to decrease static pressure loss through the coil. This fin is ideal for systems where airside pressure drop is a major concern. Reducing pressure drop through the coil results in lower fan brake horsepower and system energy

· Electric and hot water reheat coils are provided on many types of VAV terminals. There are selection criteria for each that should be considered both to ensure proper unit performance and to distribute the heated air properly into the space. With all however the engineer should assure that the discharge temperatures and air quantities will provide a comfortable space and provide ventilation

· Reheat does not dehumidify. That is my biggest pet-peeve of misconception of HVAC people. Reheat does not dehumidify. It removes NO moisture. It does reduce the RH of the supply air but the ONLY thing that removes moisture is a cold coil. The reheat allows the cooling coil to run and supply dehumidified air without overcooling the space.

· Automatic ResetThis safety feature is included on all Electric Coil units. This is the first line-of-defense for thermal protection of the coils. The Automatic Reset will trip if the air surrounding the coils is too hot often caused by insufficient airflow through the duct. The Automatic Reset will trip at an air temperature of approximately 130 °F which will break the control signal to the heater. Once tripped the Automatic Reset will reset

· Without the reheat the room will get too cold in order to satisfy the dehumidification setting. The reheat does have an added advantage in that it assists in the dehumidification process but that is not it s main purpose. Typically any heating coil located in a fresh air supply (OA) is usually called a preheat coil.
