Chambers with a carefully controlled internal climate are crucial for experiments which need to be carried out under set temperature and humidity conditions.
The values of temperature and humidity might need to be kept constant for days on end, or may need to be varied continuously to follow natural daily cycles.
Whether for research on greenhouse gasses from livestock production, animal behaviour and nutrition or for industrial processes, no pollution’s latest line of Controlled Climate Chambers give technicians the possibility to replicate specific conditions, with great flexibility.
Chambers are typically constructed in AISI 304 or AISI 316 food grade stainless steel, to resist corrosion even in the harshest environments. Chambers usually need to be washed and sanitised frequently, so great care is taken in the design and construction to make sure that no build-up of dirt or deposit of water is allowed on horizontal surfaces.
Materials are carefully chosen for the chamber construction and for all accessories, and rubber seals and sealants used to make the system air-tight are tested in house before the use on site, and have been validated by years of successful installations.
A solid construction and use of robust accessories like hinges and door handles guarantees years of continuous use. Transparent sections can be realised in single or double glazing, depending on the level of thermal insulation required, and always make use of security, shatter-proof laminated glass panels. When glass cannot be used for safety reasons, scratch resistant polycarbonate panels are used instead.
Sealing from the outside is of critical importance for maintaining internal conditions and for making sure that no gas escapes. All hatches and doors are fitted with rubber seals on the whole perimeter, and all passages are carefully sealed during installation. The chambers, depending on the experiment, can be kept at a slight positive or negative pressure by controlling the airflow.
In order to maintain the desired internal conditions, the chambers are fitted with powerful and independent Air Handling Units. These not only maintain the set point Temperature; Humidity is also controlled, and drying or humidification can be carried out.
Typically Temperature can range from 0°C to 45°C and above, depending on the needs.
Relative Humidity can range from 30% to 99% and saturation.
To achieve these ranges a careful control of airflow, both re-circulating and extracted, has to be achieved. This is done by a combination of high efficiency fans and blowers, all independently regulated through frequency controllers.
Fresh air inlet ports and exhaust air outlets are typically shutter controlled.
All parameters are governed by a custom-designed software, operating on a PLC. Operation can be local or from a PC based supervisory system, which also takes care of regularly downloading and storing all critical data from the chambers.
In case of experiments involving housing animals for prolonged periods of time, safety becomes a priority. All chambers are fitted with one or more emergency hatches which open to allow fresh air inside the chambers in case of failure of the control system. The system has a built in redundancy, so also if a major failure occurs, the well being of the animals is guaranteed.
Depending on the level of complexity required, the Control System can manage daily temperature cycles, night and day lighting conditions and even sudden events like heat waves and cold spells.
All critical parameters are remotely accessible through internet based communication, so the operation of the chambers can be remotely monitored. Alarms can be sent through e-mail or SMS to supervising technicians, and the system can be checked by our service team to make sure it is always operated at it’s maximum efficiency.
A number of accessories can be delivered with the chambers, depending on experiments and specific needs. These include feed bins and water troughs for continuous intake measurement, stanchions and guarding rails for housing the animals and excreta collection trays for subsequent analysis.
