Stability walk-in rooms are an ESPEC North America specialty, designed for light-duty testing or long-term steady-state evaluation of pharmaceuticals and other products.
Our panelized walk-in chambers use urethane-foam panels in a stainless steel or galvanized skin. The panels are locked together with internal cam latches. This is the same construction used for walk-in coolers in restaurants and supermarkets, but of a higher quality.
ESPEC has standard air conditioning systems, called Modular Air Plenums (MAP). These MAPs are designed with the proper heating, refrigeration, and humidity control to achieve your desired performance and capabilities. The MAP simply rolls-up to an assembled panel chamber to complete installation.

In addition, the SCP-220 programmer makes running an ESPEC environmental test walk-in chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand.
