In the last years the energy saving subject has become increasingly important as the burning of fossil fuels for power generation is the largest source of CO2 emissions. This gas is now considered the major accused of global warming. The topic raised in the agenda of many private and public stakeholers who committed in providing subsidies to those companies investing in the use of energy-saving machines.
ACS paved the way to energy saving operations in the environmental testing field in 2004, obtaining flower® patent: the first energy-saving chamber.
Focusing as always on continuous improvement, today ACS is proud to present the NEW flower® with even higher performance, which can guarantee up to 70% energy savings compared to a conventional machine of similar performance.
With the new flower®, when the requested cold is less than that available, the exceeding cooling capacity is stored and later recovered in the following cooling phases, increasing efficiency and decreasing energy wasting.
Protecting and preserving the environment is one of our company's highest priorities, which is why it is certified to ISO14001. In line with its sustainability policies, ACS has been conducting research and development to reduce energy consumption and to increase the use of ecological and recyclable materials in order to develop products that reduce environmental damages at all stages of the product lifecycles.
The chamber, “flower®”, is the first result of this research, a truly innovative product in the field of climatic test chambers, thanks to its special design.
Reduced energy consumption up to 70%
It consumes about 70% less energy during the stabilization phases due to the unique and “patented” system which includes:
Reduced noise level at 50%
50% noise reduction is obtained due to:
These advantages are combined with the use of “environmentally friendly” materials during the production phase:
* The “cold sink” consists of a mixture of water and glycol having a specific solidification temperature of around -20°C. There are two heat exchangers inside the cold sink; one acts as an evaporator and the other as a super-cooler. When the cooling powers required are very low, the control system of “flower®” chamber keeps the rotation speed of the mechanical compressors at the minimum allowed values, and the excess coolant evaporates in the evaporator situated inside the cold sink; in this way the chamber accumulates a reserve of "cool" to be used at a later stage.

Control and management system and interfaces
Controlled by PLC and Advanced HMI
There is a wide range of possibilities thanks to the built-in MyKratos™ and MyAngel24™; multichamber control also available upon request
Electromagnetic closing system
Ensures the security of environmental tests
Air treatment system
Ensures a precise control of the climatic parameters inside the chamber with minimal thermal inertia; an axial fan allows rapid temperature variations of both air and specimen.
Humidification system (only climatic version)
The humidifier with a self-contained heater and dedicated controlling S/W offers two great advantages:
- it does not require distilled or demineralised water to operate properly
- it uses ‘dry’ vapour in order to avoid condensation on the specimens and to reproduce real environmental conditions
Comparison with a similar performing chamber
ACS has tested its chambers, comparing them with its competitor’s best product, both in stationary conditions and according to international standards.

24 hours climatic test, which combines conditions of high humidity with ascending and descending ramps and subsequent stabilization period
25% ENERGY SAVING!
System includes the following components:
Mechanical cooling based on single stage system (-40°C) or cascade systems (–70°C). The cooling system is realized with semi-hermetic alternative type compressors including an automatic injection-type protection system. This protects the compressors when they are cooling down from high temperatures.
The chamber is heated by means of electrical heaters, protected by safe thermostats that disconnect overall chamber main power components (such as compressors, fans and heaters) in case of accidental over-temperature.
Direct humidification occurs through an electrical vapour humidifier.
The chamber is equipped with a water storage tank (about 18 l capacity) and a water connection on the back of the chamber for automatic refilling.
There are three ways to ensure the water supply needed for any kind of climatic tests:
In order to reduce water consumption, water recycling can be activated through a button on the control panel (only possible when the specimen does not contaminate the water during the test).
Dehumidification is performed by the condensation cooler (dew point cooler) directly connected to the refrigeration circuit. This principle permits high stability of parameters in conjunction with energy-efficient dehumidification.
Temperature Measurement with Pt100 thermal probe Class A, max precision 0,3K.
Relative humidity measurement with Assmann psychrometric system complete with Pt100 thermal probes.
Relative Humidity range from 10% to 98% within the temperature range [+10°C; +95°C].
Dew Point range:
The values refer to the basic version at ambient temperature of +22°C, with temperature and humidity measurement made in the air inlet.
The chamber is equipped with a PLC (Programmable Logic Controller) for managing all the chamber’s functions and safety interlocks. The HMI system consists of a 10'' on-board panel and a remote control via mobile and desktop devices. MyKratos™ software (including MyAngel24™ Interactive Assistance System), is available both from the on the on-board panel and remote devices with the same user-friendly graphical interface.
On-Board Panel: 10'' Touch Panel, 16 M colours with a touch menu with related pop up screens, allowing the control of all the chamber functions.
