Refrigeration System - Multi-Circuit, Copper Tube Coil Extra large surface provides maximum cooling efficiency, excellent heat transfer and low air resistance

Precise circuiting gives uniform refrigerant distribution

Refrigeration System - Coil is constructed of precisely spaced ripple edged aluminum fins fitted to durable seamless, rifled copper tubes

Rifled tubing provides enhanced heat transfer which results in maximum coil performance when combined with fin design

Fins are strengthened to resist bending and are equipped with collars that grip tubing for maximum contact area

Flared tubing connections and silver soldering provide tight, leak-Proof joints

Long life copper tubing is corrosion-resistant and easy to field service

Coil is thoroughly factory tested under high pressure to ensure leak-Proof construction

Expansion Valve

Refrigerant Piping and Drain Connections - Refrigerant line inlets (knockouts) are provided on both sides of the cabinet

Refrigerant lines require sweat connections and are made internal to the cabinet
