Especially designed for steady-state operation

Stability walk-in rooms are an ESPEC specialty, designed for light-duty testing or long-term steady-state evaluation of pharmaceuticals and other products.

Panelized Chamber/Room

Our panelized walk-in chambers use urethane-foam panels in a stainless steel or galvanized interior 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.

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.


  • Stainless steel interior (or galvanized for savings)
  • Painted galvanized steel exterior for long life
  • MAP service doors are hinged (no tools or lifting)
  • Easy access to components
  • Reliable steam generator system for humidity applications
  • Sheathed electric heaters for safety and reliability
  • Adjustable vanes in supply grille allow directing of airflow as needed
