Overview

The ESPEC Global-N Series Temperature Cycling Chambers are advanced environmental test chambers designed for fast temperature and humidity cycling to validate the quality and reliability of electronic and other products. These chambers support production and qualification level testing with temperature change rates up to 20°C per minute.

Global Features

• Available in two interior volumes: 380 liters (12 cu. ft.) and 800 liters (28 cu. ft.).
• Compact footprint: 380L model is 0.8m wide; 800L model fits within 1.2m by 2m space (except -15CW models).
• Fast temperature cycling capability up to 20°C/min.
• Controlled humidity available on select models.
• Modern stainless steel design with adjustable controller pod for ergonomic use.
• Lower sound levels, including air-cooled models.
• Compliance with international standards such as JEDEC, IEC, and MIL-STD.
• CE-marked for safety and compliance.
• Service-friendly design with hinged access panels and three levels of overheat protection.
• System controller provides detailed alarm messages and troubleshooting guidance.
• Analog refrigeration gauges for system monitoring.

Standard Features

• Non-metallic thermal break around doorframe to prevent temperature transfer.
• One 4" (100mm) cable port with flexible silicone plug; additional ports optional.
• Dew trays to catch condensation during humidity testing.
• Adjustable stainless steel shelf supporting up to 45 kg (100 lbs).
• Heavy-duty casters with adjustable feet for leveling and securing the unit.

Performance and Model Options

Models vary by size and performance, offering temperature cycling rates from 5 to 20°C/min. They meet international test standards and can be customized based on specific test plans.

ESPEC offers performance evaluation services to guarantee model suitability based on customer test requirements.

System & Performance Options

• Humidity control modes (EGNL & EGNX models) with extended low and ultra-low humidity ranges.
• Attached air-cooled condensers for water-cooling impractical environments.
• Product temperature control for faster and more accurate temperature cycling.
• Data logging via chart recorders, paperless recorders, Ethernet, or computer interfaces.
• ECA modification for conditioning remote equipment outside the chamber.
• Dry air purge to maintain extremely low moisture levels (requires compressed air).
• Liquid nitrogen injection to boost cooling rates.
• Additional accessories such as shelves, cable ports, inner glass doors, humidity water filters, and emergency stop buttons.

Advanced Control Features

• Adjustable height controller pod with ESPEC’s SCP-220 touch-screen programmable controller for easy setup and monitoring.
• Optional product temperature control monitors actual product temperature, enabling faster ramp rates and shorter soak times by overshooting air temperature setpoints.
• Web Controller embedded server/software allows remote monitoring and programming via any PC with a web browser and LAN access, requiring no local software installation.
