STJH-CLEANROOM-DX-AIR-CONDITIONING-81KW

Cleanroom Direct-Expansion Air Conditioning Unit 81 kW

An 80.7 kW gross-cooling precision DX unit with 7.2 m3/s airflow and two 2.41 l/s glycol heat-rejection paths.

80.7 kW gross cooling
7.2 m3/s airflow
Two 2.41 l/s glycol paths

Introduction de produit

The mid-capacity DX selection increases gross cooling to 80.7 kW and nominal airflow to 7.2 m3/s. Its documented twin 2.41 l/s glycol flows and R410A refrigeration match a larger coil and compressor selection for cleanrooms with medium-to-high sensible load.

Key Features

Higher mid-range output

The coil and compressor combination adds cooling capacity above the 73 kW build without moving to the largest selection.

Twin heat-rejection flows

Two glycol paths support the dual refrigeration circuits and their external heat-rejection connection.

Precision air-volume control

EC fan speed can be matched to the 7.2 m3/s distribution requirement and filter condition.

Applications

Medium-to-high-load cleanrooms, electronics production, precision laboratories and technical suites requiring close temperature and humidity control.

Solutions for Your Application

The process load sits above the smaller DX model but does not justify the largest cabinet selection.Apply the 80.7 kW build at the verified sensible and latent design point.

Heat-rejection pressure loss can differ between the two glycol branches.Balance both 2.41 l/s paths and provide accessible strainers and isolation at the unit connections.

Options disponibles

Air discharge direction, reheat, humidification, filtration, glycol pumping accessories, compressor controls and monitoring interfaces can be selected.
