Terra Universal Product Desiccators

Terra Universal Smart Desiccator systems maximize yields of sensitive materials with an automatic monitoring and control system that works by the operator setting the humidity Level.

The feedback system continuously monitors the cabinet’s relative humidity and then regulates the dry nitrogen supply. This is more economical than a constant purge system that is slightly more cost effective in the capital outlay.

smart-desiccator

It has an LED display and sensor module making it very user friendly.  The only installation considerations are one Nitrogen supply and one low voltage power supply. The Nitrogen inlet fitting is 3 mm-OD tubing, set to 100 PSI.

Made from 304 stainless steel construction. Rugged design for clean room environments with catches for the door designed for constant use. The cabinet is designed with a gasket that holds a tight seal and will withstand low humidity over the service life of the cabinet.

Prices include the humidity control module, sensor, and Automatic RB® Valve, which ensures safe pressure release. Order racks and shelves separately, call us for a complete package quotation.

Nitrogen Purge Cabinets

State of the Art and cost effective

A nitrogen membrane provides a low-cost, highly efficient means of separating air into its component gases. Because this technology requires no moving parts and consumes relatively little energy, it is surprisingly economical to operate and maintain—the main expense is the energy required to provide a stream of compressed feed air. Each system contains gas pressure control valves and instruments, a coalescing filter and carbon filter (which removes particles and liquid vapors from the feed line), and the nitrogen membrane module.

This Nitrogen Generator will make a fast return on investment if you are running multiple cabinets.

  • State of the art membrane separation technology produces dry nitrogen up to 99.9% purity
  • Eliminates drawbacks of conventional nitrogen sources—gives you control of rate and purity of nitrogen production
  • Delivers gas flows up to 400 SCFH or more depending on nitrogen purity requirements (even higher flows possible if only dryness is desired)
  • Compact, lightweight design allows set-up wherever there’s a compressed air supply
  • Ideal for the complete range of cleanroom applications—from glove boxes to automatic storage systems
  • Simplicity of field-proven design ensures completely reliable, economical operation, virtually eliminates maintenance
  • Three models available with three flow ranges.

Design Simplicity Means Easy, Reliable Operation


Because the heart of the system, the membrane module, contains no moving parts, it requires no maintenance. The only attention a system typically needs is an occasional recalibration of the oxygen analyzer and filter change. Even if one module’s performance should drop below purity specifications, it can simply be valved off until it can be repaired or replaced

Once the system is set up, you simply switch to START and push the RESET button to open the feed valve. After about three minutes, when gas purity levels are met, a product valve opens to deliver the nitrogen gas to your process line.

Each Nitrogen Generator consists of a membrane module, controls and instrumentation, and coalescing filters and traps to remove oil and liquids, organic contaminants, and other particulates from the feed air. Installation merely requires piping compressed air to the system, piping the nitrogen and oxygen-rich streams to their destinations, and calibrating the system’s oxygen analyser from time to time.
