ESPEC North America builds dozens of walk-in test chambers every year for top companies testing automotive, electronics, communications, aerospace, and other products. Drive-in test 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 panelized walk-in test 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 Controller

In addition, the P-300 touch-screen controller makes running an ESPEC environmental test chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand. The P-300 touch-screen controller can be managed remotely via our new Ethernet/LAN-based Web Controller or RS-232 serial port. USB access is standard.

Features for Panelized Walk-in Chambers

• Modular panel test chamber featuring stainless steel interior
• Exterior is embossed galvanized steel, stone white coating
• Insulated panel floor with non-slip surface and multiple drains
  - Loading up to 600 psf, suitable for foot traffic or small carts
  - Optional: No floor, medium-duty (900 psf), or heavy-duty (1,500 psf)
• MAP service doors are hinged for easy access to refrigeration components
• Reliable steam generator system for humidity applications
• Adjustable vanes in supply grille allow directing of airflow as needed

The exclusive 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.

USB port for upload/download of test profiles and test data

• Test programs can uploaded or downloaded from the P-300 via USB thumb drive.
• Create, edit, and store programs on a PC using the included Pattern Manager Lite software.
• Accurate, repeatable testing by uploading the same program to multiple chambers.
• Create your own back-up archive of programs, and get additional profiles from ESPEC's library.
• Retrieve and download test operation data via USB thumb drive. Data timeframe is selectable.
• For integrity, viewing test data on a PC and exporting to Excel requires included Pattern Manager Lite software.

Energy-saving operation

Invisible to the end user, the P-300 uses advanced cooling control via an electronic expansion valve, saving energy and improving temperature stability. Sophisticated future-looking algorithms make temperature ramping faster and smoother. These high-end features are unique to ESPEC. Additional improvements in refrigeration and heater operation will make the next generation of ESPEC chambers the most energy efficient ever.

Additional capabilities

• Store up to forty programs, as well as three different constant-mode set-ups.
• Multilingual display in English, Japanese, Chinese, or Korean.
• Alarm diagnostics and history, plus a ‘back trace’ feature for troubleshooting.
• Three programmable timers allow the user to set reminders for maintenance or other actions.
• Energy saving by using only one compressor when testing above -10°C (for cascade refrigeration models).
• Optional Ethernet/browser-based Web Controller access can also be used to upload and download programs, as well as data.
• Optional Product Temperature Control allows faster ramping to the desired conditions on the sample.
• Computer interface options for specialized programs: RS-232/serial or GP-IB.
