The IAC Climate Chamber (Dycometal model CCMM-20/8000) was originally installed in 1993 and completely renovated in 2017. Its main features are listed below.:
The main features of the camera are:
The following is a brief description accompanied by photographs of the various components that make up the Climate Chamber.
The Main Module is the Climate Chamber itself. Its useful inner dimensions are 1890 mm (height) x 1890 mm (width) x 2200 mm (depth), and equipment to be tested is placed inside the chamber. It is planned to install a general-purpose
stainless steel work table for the mounting of optical benches or similar equipment. The two halves of the double door are closed together. On the upper part of the right door (identified in the photograph by the handle which is turned first
when opening) is a safety switch which halts the operation of the chamber when the door is opened. It is therefore impossible to enter the chamber without interrupting any test in progress.
The control panel hangs on the left side of the Climate Chamber. Its main element is the Eurotherm-2604 commercial controller, with which we communicate via an RS232 series port connected to the control PC. The Climate Chamber is plugged directly into the triphase voltage box on the wall.
The refrigeration unit is located outside the Testing Room and is connected to the Climate Chamber via two holes drilled in the wall. It consists basically of a compressor and an R-452 A (without CFCs) refrigerant gas deposit. The
electrical cables also traverse the walls. The unit is started automatically under the general control of the chamber.
The chamber is controlled by a PC dedicated exclusively to the Climatic Chamber via an RS-232 series port. The control program is called 'iTOOLs' (from Eurotherm).
The chamber also permits the passing of electrical cables through the left wall to external recording,measuring, or control equipment. There are four drilled apertures of different diameters and heights. Any unused apertures
must remain sealed with their respective threaded teflon stops. Moreover, to ensure the air-tightness of the system, those apertures that are used for passing cables must be rendered as air-tight as possible through the use of,
for example, Armaflex-type sealant. For equipment support inside the chamber, a 90 cm x 75 cm stainless steel antivibration optical table is provided (see photograph)
