Hidden Costs of Acrylic Enclosures

Compared to acrylic, static-dissipative PVC offers three benefits that reduce operating expenses and drive down overall ownership cost of a clean room, glove box, hood, desiccator, or other enclosure.

Contamination Control

Acrylic is a prolific static generator. The back-and-forth motion of wiping an acrylic surface creates positive and negative surface charges that attract and hold small particles.

The resulting static cling makes it difficult to remove contaminants from the charged surfaces without the use of ionizing equipment or frequent cleaning with special anti-static solutions. Variations in the surface charges can lead to unpredictable release of aggregated particles, threatening contamination-sensitive material.

For this reason, expect acrylic to drive up the cost of keeping an acrylic enclosure contamination-free.

Don't Turn Your Clean Enclosure into a Particle Magnet! Non-dissipative plastics quickly accumulate surface charges that attract contaminants. If the panel on the left clings to this many test spheres, just imagine how many micro-particles it attracts!

Germ Control

An aseptic environment requires frequent sterilization with disinfectants such as alcohol. Unfortunately, most common biocides, including industry-standard IPA solutions, degrade acrylic, causing cracks and discoloration.

Static-dissipative PVC, on the other hand, resists alcohol and most other sterilizing solutions, supporting standard disinfecting procedures and extending the life of your enclosure.

ESD Control

Acrylic’s most serious hidden cost becomes apparent when static-sensitive materials are destroyed or degraded by unpredictable electro-static discharge (ESD).

Whether it results from hand-wiping the acrylic surface or from the micro-frictional effects of a strong airflow, surface static charge poses serious threat to semiconductor, electronics, and other sensitive materials. In fact, acrylic supports the accumulation and discharge of up to 20,000 volts. This danger is especially acute in a low-humidity environment like a nitrogen-purged glove box or desiccator.

Why Consider Acrylic?

Despite these disadvantages, acrylic is widely used in clean rooms and other critical environment applications. Its low initial cost, light weight, transparency, and strength make it an attractive choice in many situations, and Terra offers most of its enclosures in acrylic in order to provide a competitive option.

In critical applications, however, acrylic should be avoided. Lower total ownership costs – due to easier cleaning, sterilization, and ESD control – quickly justify the initial expense of a static-dissipative PVC enclosure.

Cleanroom Power Distribution Diagram

Terra’s Power Distribution Modules (PDM's) drastically simplify connection of FFUs, lights, and control panels. They also allow room for growth. FFUs and lights use quick-connect fittings so they can be added at any time to existing PDMs, without the need for an electrician or hard-wiring.

Clean and Durable Powder Coat Finish

Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

WhisperFlow Quiet Operation Reduces Distracting Background Noise

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).

Seismic Safe Cleanroom Design

Terra’s modular cleanrooms are designed with seismic safety in mind. Rigid steel frames and ceiling grids are designed with sufficient factors of safety to provide vertical and lateral strength recommended by professional engineers. Both hardwall and softwall designs can be installed to adhere to local seismic codes. Optional seismic and structural calculations can be drafted and stamped by a licensed PE to help meet municipal permitting requirements.

Highest Standards For Electronic Components

Terra’s electronic components are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.
