HD-202 Model is a floor-style environmental test chamber with temperature and humidity functionality.
STRUCTURE. The internal workspace is lined with type 304 stainless steel for a vapor-tight internal construction . The exterior has a durable powder-coat finish over heavy-gauge steel for a long-lasting clean look. Between the two layers is 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 HD-202 Test Chamber has a proprietary baffle and fan design combination. This optimizes temperature and humidity conditions within the workspace.
HEATING SYSTEM. HD test chambers feature heating systems equipped with open ceramic-core nichrome heaters for reliable and accurate temperature control within ±0.5°C.
HUMIDITY SYSTEM. The humidity system has a standard range between 20% and 95%. To extend your humidity range, see the optional features section.
COOLING SYSTEM. The cooling system in the HD-202 consists of a self-contained mechanical refrigeration system with a cascade configuration, and an air-cooling condenser. An optional water cooling-condenser is available.
Add boost cooling with liquid LN2 or CO2 for even faster pull-down rates. It's a great option for stress tests that require rapid cooling. Even without boost cooling, AES standard cascade refrigeration systems have the fastest standard change rates of any environmental test chamber manufacturer. See Basic Specifications tab below.
INSTRUMENTATION. HD Series Test Chambers have incorporated the AESONE CONNECT creating a robust connected device for a standard and uniform interface making operation easier. Learn more in the Instrumentation Tab below.
