Test Navi

The most energy efficient ever: Energy savings of up to 70% over previous models.

Technology allying high performance and energy-savings

Thanks to various means of refrigeration control, and optimization of the heating/ cooling capacities via the N- instrumentation, our chambers can achieve up to 70% energy-saving.

New refrigeration circuit

Extended water flow control and minimum refrigeration capacity are achieved thanks to our "Smart Refrigerator & Dehumidifier system". This technology allows reducing electrical consumption while creating a very accurate environment inside the chamber.

Sub-circuit for further savings

Models equipped with a sub-refrigerator achieve great eco operation. The refrigeration circuit switches between refrigerators to optimize the chamber consumption according to the minimum required power.

Make your own chamber with a variety of options

A variety of options to modify flexibly

Create your "just-fit" chamber by ordering only what you need. To take door as an example, choose a door with or without window, with or without hand-in ports, the number of hand-in ports, etc. Numerous options are also available as retrofit kits.

Wide-view door compatibility extended (Option) PL/PR/PU-2,3,4

Dew controlled all-glass door is ideal for physical observation; now available for several models. Multi-layer EC glass able to withstand temperatures from -40 to +120°C. Hand-in ports on the glass can be an optimum choice (patent no. 4137894)

Electrochromic viewing window

Switches opacity to transparent state by chamber lamp. The test area can be observed while the lamp is on.

Cable ports on both sides (option)

Possible to install a cable port on the right side (option), thanks to a redesign of the internal space (machinery, customized space, etc.)

Trace-back function and online diagnostic service

A feature in the controller allows to automatically save test data tracing back just before the chamber error occurs. The test data can be exported to USB flash drive. Send data to the Customer Support Desk via our website for effective and quick troubleshooting. Save time and money by minimizing on-site visits and analysis time.
