Panelised Walk-in temperature and humidity testing rooms

ESPEC 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.

Panelized Chamber/Room

Our panelised 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.

Temperature and Humidity Control

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.

Easy-to-use Programmer

The ESPEC P-300 controller has USB and Ethernet features to make programming and data collection easier than before. The user interface uses tabs for faster access to any screen. Standard USB and optional Web Controller/Ethernet interfaces make programming and data acquisition much simpler. In addition, improved algorithms make operation faster and smoother.
