Introdução do produto

This smallest selected DX build combines four scroll compressors in two refrigerant circuits with three 2.9 kW EC fans. The 3100 x 890 x 1980 mm cabinet delivers 6.9 m3/s for medium clean electronics or test suites requiring packaged precision cooling.

Características-chave

Two-circuit DX staging

Four compressors divided between two circuits allow the refrigeration output to respond in steps to changing load.

Three EC supply fans

The fan set delivers the documented air volume with speed-control capability for the distribution system.

Narrow deep cabinet

The 890 mm depth helps preserve aisle space along the long 3100 mm equipment face.

Applications

Medium electronics cleanrooms, precision test suites, controlled technical rooms and manufacturing areas with high sensible heat.

Solutions for Your Application

A comfort air conditioner cannot maintain conditions as process heat changes rapidly.Use staged scroll compressors and EC fan control around the measured precision load.

One refrigeration stage would provide coarse capacity steps at part load.The four-compressor, two-circuit arrangement divides output across several operating combinations.

Opções disponíveis

Upflow or downflow discharge, electric reheat, humidifier, filter upgrades, glycol heat rejection, leak detection and communication interfaces are available.
