Industrial-quality chambers for combination testing with vibration systems

For years Temp.humidity and vibration compatible Chambers have been the workhorses of the environmental test chamber industry. Originally created to meet military test standards, their flexible design has made them suitable for a wide variety of applications. Fast temperature changes of 5 to 25°C/m. are possible, even with significant loads. The chambers have a removable floor, allowing integration with vibration test systems. Custom designs are common, allowing configuration to meet your exact requirements.

Special model can interface with both vertical and horizontal vibration systems

In addition, the touch-screen controller makes running an Grande environmental test chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand. The Touch Screen Controller can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB/Lab View.

Nearly every Agree chamber we build is designed per the application. Here is a review of what is possible with a custom designed chamber from Grande.

Feature

Capacity: 63 L to 6000L

Temperature Range: -70 to 180C

Humidity Range: 10-99%RH

Cooling rate: 2-3C/min (standard), 5C/min, 10C/min , 20C/min as option

Vibration: maximum up to 5000kgf , 100g

Cabinet

Full-opening door with multi-panel heated window & interior light

Chamber floor designed to be changeable to accommodate different “floor plugs” for vibration systems. Standard floor plug provided is “solid” for non-vibration applications (other floors optional). Embedded perimeter heaters in floor plugs to avoid condensation and freeze-up, plus Teflon glides in floor slot make floor replacement very easy.

One 50mm cable port with flexible plug centered in the left hand wall (additional ports optional)

Refrigeration and Plenum

Rear-mounted plenum with cooling coil and nichrome wire heaters

Two ¾ h0p blower motors with one-piece stainless steel shafts

Non-CFC cascade refrigeration system using semi-hermetic Copeland Discus compressors

Hinged service access doors with lockable snap-action latches
