Hielkema Stability Chamber


The Hielkema Stability Chambers are available as standard stability chambers with fixed dimensions or as custom built walk-in stability chambers.
The standard Hielkema stability chambers are ideal for conducting stability tests and for maintaining constant climate conditions. Areas of application include the pharmaceutical, packaging and food industries. In addition, these stability chambers can be combined with special lights to use them for growing insects and plants.

The standard stability systems feature a stainless steel interior chamber with stainless steel wire grates (or perforated platforms if required) and are delivered with 4 stainless steel adjustable legs as standard. The stability chambers also feature an internal air circulation system that consists of a back panel with special air outlet slots and ceiling-integrated air extraction. This ensures homogeneous and direct air circulation across the wire grates, resulting in higher temperature accuracy and a shorter recovery time after opening and closing the door.

The walk-in stability chambers are available in sizes of 1700 litres or more and are installed and certified on site. These chambers are all custom built. Would you like to know more about the possibilities? Please feel free to contact us.
