ACS Altitude Test Chambers
Product Overview
Since 1953 ACS has been designing and developing a complete series of standard chambers for vacuum tests up to 1 mbar (equivalent to 150,000 feet altitude)
ACS Altitude Chamber at 150L, 500L, 1000L is available in both thermostatic (temperature and pressure control) and climatic (temperature, pressure, and humidity control) versions.
Also available in ES Version, allowing environmental performance, whilst maintaining the same footprint and volume of the lower specification versions.
Contains a special wall thermoregulation system (optional) which guarantees the best functioning below 300 mbar, thermoregulating the test environment by radiation.

Key Features
This range of altitude test chambers is available in both versions: thermostatic (temperature and pressure control) and climatic (temperature, pressure and humidity control) in volumes of 150, 300 and 1000 liters. The 500 and 1000 l models are also available in the 5 K/min version. A special wall thermoregulation system (optional) guarantees the best functioning below 300 mb, thermoregulating the test environment by radiation.
BENEFITS
- Heated inspection window ensures clear visibility of the test compartment
- Excellent thermoregulation performance and control of pressures inside the test compartment thanks to the thermoregulation of the walls
- Remote control
- Remote support
- Robust structure.
- Top-of-sector performance, in terms of both the breadth of the regulation field and the speed of the temperature and pressure variations.
- Optimized system for the thermoregulation of the walls of the test chamber in both the heating and cooling phase, even for pressures close to the minimum value (optional).
- All-in one MyKratos TM software: all functions in one application.
- The new control system – including MyAngel24TM – makes it possible to control, monitor and assist the chamber in any place at any time in multiple ways (WiFi, Ethernet, mobile networks) via mobile and desktop devices. Industrialization of the control, cooling, humidification, and pumping devices, in order to guarantee maximum quality and reliability as well as ease of access to the various maintenance points.

Software
Control System
The chamber is equipped with a PLC (Programmable Logic Controller) for managing all the chamber’s functions and safety interlocks.
The chamber basic control is supplied by Weazy™, a very flexible HMI accessible on the 10 inch on board display.WinKratos (optional) allows the complete management of the chamber functions: from manual control to the creation (through the graphic editor) of test profiles, including monitoring and recording, processing, graphical representation and analysis of data.
MyAngel24™ (optional) is the Advanced Services Platform developed by ACS to offer fast, effiicient and secure remote activities, allowing Automatic Reporting and Preventive Maintenance.
Weazy™ main features:
- Ethernet connection to the chamber
- Visualization of measures and recordings
- High configurability of chamber parameters
- Program and Manual chamber operation modes
- Delayed start of a program
- Automatic notifications of events and alarms
- 7 days data storage
- System available in several languages
The MyKratos™ management software is embedded in the machine in built-in and completely dedicated hardware, which allows the control and management of the chamber functions. No installation is required, and it can be accessed from a PC via web browser or via the free app developed for tablets and smartphones. MyKratos™ allows multiuser and multilevel connections, even from different devices.
