ESPEC North America builds dozens of walk-in chambers every year for top companies testing automotive, electronics, communications, aerospace, and other products. Drive-in chambers for automobiles are one of our top specialties. Stability walk-in rooms are another 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 that lock together with cam latches. This is the same construction used for walk-in coolers in restaurants and supermarkets, but of a higher quality. The panels we use have a stainless steel interior skin to be stronger and impervious to extreme conditions. The seams between panels are carefully sealed to protect from leaking that may affect performance or damage the panels. Doors and windows have embedded heaters, as well.
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.
