Need help finding the right ESPEC chamber?
Try our new chamber selector tool ⏩

Over 70 different Global-N models allow you to choose the size and performance best suited for your test applications. Temperature cycling rates from 5 to 20°C/min. are possible. Two different ultimate low temperatures are available: -35°C or -70°C. The Global-N series require the least amount of floorspace for this level of performance.

  • Five chamber sizes: 114, 380, 470, 800, and 1000 liters (4, 12, 16, 28, and 35 cubic feet)
    NEW: Four cubic foot model has the interior size of a benchtop, but rates up to 30°C/m
  • Temperature cycling as fast as 20°C per minute
  • Reliable Scroll compressors on most models
  • Humidity testing capability also available
  • Casters, shelf, and cable port are standard
  • CE-mark or ETL-listed electrical panel conforming to UL 508A

These chambers feature the classic ESPEC look of stainless steel with a new, modern style. The control console is on the door, making the footprint of the unit even more compact. A simple, but secure, door latch is easier than ever to use.

ESPEC can add safety options for testing lithium-ion batteries or other products. See the options tab for a list or the Battery brochure below.

In addition, the P-300 programmer 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 can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB. USB access for saving programs and data is standard.

Features for Global-N Temperature Cycling Chambers
  • P-300 touch-screen programmer with USB port
  • High performance, reliable Copeland Scroll compressors*
  • Lower sound levels, even for air-cooled models (click on model numbers to see specs)
  • One 4" (100mm) diameter cable port with flexible silicone plug
  • Heavy-duty casters with adjustable feet for leveling unit
  • Refrigeration gauges and hinged service panels for easy maintenance
  • Non-metallic thermal break around the doorframe for thermal integrity
  • Dew tray on the door to catch drips when opened
  • Adjustable stainless steel shelf with heavy-duty support rails, supports 100 lbs.

* Models without 'L' suffix have Copeland Discus compressors

New P-300 controller with USB

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.

DEMO: See how easy the P-300 is

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.
