HD-548-17 - Temperature with Humidity

Overview

HD-548 Models are available in multiple performance levels giving you the rise and pull-down rates you need to meet test requirements and manage live load testing. Built on swivel brake casters, this floor-style environmental test chamber with temperature and humidity functionality still offers flexibility in your lab space or on the production floor.  

All large floor models, over 13 cubic feet, are available with escalating performance speeds, for more rate information see specifications below.

STRUCTURE.  The exterior cabinet design is an engineered sheet metal frame that is precision laser cut and formed with powder coat bone color and matte finish.

The internal workspace walls are type 304 stainless steel for vapor-tight internal construction. The exterior has a durable powder-coat finish over heavy-gauge steel for a long-lasting clean look. And between the two layers, you’ll find highly efficient, low k-factor thermal insulation. This chamber is built to last for many years.

CIRCULATION SYSTEM.  Air circulation is crucial for environmental testing. The airflow system has a proprietary baffle/fan design combination to optimize temperature and humidity conditions within the workspace. Air flows into a plenum behind the back wall of the internal workspace for conditioning to the required setpoint. Pushed by large stainless steel blower wheels, air enters the workspace through a four-inch area at the top of the workspace’s back wall. A directional baffle forces the conditioned air across the ceiling toward the front door, redirecting and dispersing the airflow throughout the workspace. An intake vent on the workspace floor along the back wall returns air to the plenum for reconditioning to the precise temperature and humidity. 

Variable-speed airflow control is included allowing you to adjust airflow to meet your test requirements and reduce noise.

HEATING SYSTEM.  HD test chambers feature heating systems equipped with several finned nichrome sheath bars that operate independently within the plenum for reliable and accurate temperature control within ±0.5°C.

HUMIDITY SYSTEM.  The humidity system has a standard range between 10% and 95%. To extend your humidity range, see the optional features section. View RH Chart.   

COOLING SYSTEM. The cooling system in the HD Series consists of a self-contained, compact, single-stage, mechanical refrigeration system with an air-cooled condenser. An optional water cooling condenser is available.

Add boost cooling with liquid LN2 or CO2 to shorten pull-down times; it's a great option for stress tests that require rapid cooling.

INSTRUMENTATION.  HD Series Test Chambers have incorporated AESONE CONNECT, creating a robust connected device for a standard and uniform interface, making monitoring and operating easier. See the Instrumentation Tab below for more details.
