Brief Introduction

Air Cooled Heat Exchanger (ACHE) is a heat rejection equipment where the excess process heat is rejected to the atmosphere. It works on the principle of convection and conduction to dissipate heat from process fluid to air.

Primary Surface :
Round seamless copper tubes are mechanically expanded into the fin collars of the secondary surface. The mechanical expansion provides a permanent metal to metal bond for efficient heat transfer.

Tubes are staggered in the direction of airflow and only return bends are used – NO reduced tube wall in the bend radius by using hairpin bends.

Secondary Surface:
Corrugated plate type fin that is die-formed. Fin collars are full-drawn to provide accurate control of fin spacing and maximum contact with tubes

Fin Material Options:

5/8″ tubes comes standard with aluminum fin 0.2 mm thick with optional (0.254). Optional copper fin thicknesses available are (0.15) (0.2) and (0.254). Fins per inch available 8 through 14.
1/2″ tubes come standard with aluminum fin 0.15 mm thick with optional copper fin (0.15). fins per inch available 8 through 14.
3/8″ tubes comes standard with aluminum fin 0.15 mm thick with optional thicknesses available. Copper fin thicknesses available start 0.15 mm
Fins per inch available 6 through 16. Other fin types available: Lance, Sine, Flat.
Contact us for availability of other patterns, fin materials, and/or thicknesses.

Headers:

Seamless copper with die-formed holes that provide a parallel surface to the coil tube for strong brazing joints.

Connections:

Copper O.D. sweat interchangeable nozzle type refrigerant distributors. Standard coil has one distributor for one compressor circuit. An INTERTWINED coil has two distributors that provide full-face control using two compressor circuits.

A FACE SPLIT coil has two or more distributors for multiple compressor circuits.

Casing Material Options:

Galvanized steel standard with optional stainless
