Product overview

K-Series cabinet air-handling equipment includes horizontal, vertical, ceiling-mounted and slim ceiling-mounted arrangements. The reviewed I-type four-row hydronic coil tables distinguish chilled-water cooling and hot-water heating, with separate return-air and fresh-air duties. Full order codes and selected fan/coil conditions must be established for each project.

Key technical specifications

K-Series: horizontal, I type / 4-row coil references

Printed HGI table reference codes are not complete order codes. Air direction, water side, H return-air / X fresh-air duty, filter and non-standard static pressure must be specified separately. II type and other coil configurations are not represented.
